A World without Landfills? It’s Closer than You Think

A World without Landfills? It’s Closer than You Think | Zero Footprint |
Two recipients of this year’s Goldman Environmental Prize are working to abolish the practice of sending trash to landfills and incinerators. And the idea is catching on.


Padilla and Ercolini’s stories show that zero waste is not only a personal choice, but also an organized system that works at multiple levels including the community, municipality, nation, and region. Zero waste systems include:

composting, recycling, reuse, and education on how to separate materials into these categories;door-to-door collection of recyclable and compostable stuff; swap meets, flea markets or freecycle websites to exchange reuseable goods and encourage people to buy less;policy change, including bans on incineration and single-use plastic bags, and subsidies and incentives for recycling;regulation of corporations to require them to buy back and recycle their products once they are used by consumers (glass soda bottles and tires are examples of products subject to this regulation in some countries).

Zero waste systems are designed with the goal of eliminating the practice of sending trash to landfills and incinerators. Not only is this possible, it’s already beginning to happen. Ercolini’s hometown of Capannori, Italy, has already achieved 82 percent recycling and reuse and is on track to bring that figure to 100 percent by 2020.

Daniel LaLiberte's insight:

Zero Waste must include all industries, all homes, everything.  We waste so much that it should be relatively easy to cut our waste significantly, until we are on a par with undeveloped and developing parts of the world where they are already much better than us.

Renewable Energy Could Fully Power Grid by 2030

Renewable Energy Could Fully Power Grid by 2030 | Zero Footprint |

Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College. A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found.

“These results break the conventional wisdom that renewable energy is too unreliable and expensive,” said co-author Willett Kempton, professor in the School of Marine Science and Policy in UD’s College of Earth, Ocean and Environment. “The key is to get the right combination of electricity sources and storage—which we did by an exhaustive search—and to calculate costs correctly.”

Unlike other studies, the model focused on minimizing costs instead of the traditional approach of matching generation to electricity use. The researchers found that generating more electricity than needed during average hours—in order to meet needs on high-demand but low-wind power hours—would be cheaper than storing excess power for later high demand.


“Aiming for 90 percent or more renewable energy in 2030, in order to achieve climate change targets of 80 to 90 percent reduction of the greenhouse gas carbon dioxide from the power sector, leads to economic savings,” the authors observe.

Top Renewable Energy Author “Bullish” on the Future

Top Renewable Energy Author “Bullish” on the Future | Zero Footprint |
"There are many possible events that could accelerate the demise of fossil fuels—but none is required to phase them out in favor of renewables, a process that will be driven primarily by pure market economics—and far faster than most people understand." - Craig Shields, 2015


Though Craig Shields was pleased that his first two books became #1 best-sellers in their respective categories on, looking back, he has some reservations about their content.

With his current release, however, all that has changed.  “Bullish on Renewable Energy - Fourteen Reasons Why Clean Energy Investors Can’t Lose” takes a radically different tack.   [...] the book points to a remarkable truth: according to Shields, “The battle has been won. The forces of market economics are in the process of changing so rapidly that planet Earth is headed for a clean energy future far faster than anyone could have predicted.”

80% of the world’s energy is derived from burning hydrocarbons—processes that are clearly unsustainable—but I contend that we’re living in a time where fossil fuels will be replaced with clean energy in a very short period of time. But the final nail in the coffin of fossil fuels will prove to be simple economics, rather than changing public sensibilities.  ... Under the right conditions (that are becoming more prevalent every day), we can generate clean energy far less expensively than we can generate electricity with coal-fired power plants. 

Daniel LaLiberte's insight:

The inevitable demise of the fossil fuel industry can't happen soon enough.  How long will it take?  Since declining renewable energy prices are becoming increasingly more competitive than fossil fuels, the transition to 100% renewable energy is likely to happen as fast as the renewable energy sector can ramp up.   If we merely continue the growth rates we've seen over the last several years, we could be there in as little as 15 years.

Sustainability over growth: the paradigm shift at the heart of Green economics

Sustainability over growth: the paradigm shift at the heart of Green economics | Zero Footprint |
With the Green Party now polling at record levels, the predictable media backlash arrived this week.


The major stumbling block appears to be what a Green economy might look like. Many commentators seem to have grabbed hold of the fact that the Green Party, unlike other parties, doesn't condition all of its policies on the premise of economic growth.

First, it is important to point out that Green supporters as a whole reject Gross Domestic Product (GDP) as a reliable or informative economic indicator.

GDP is misleading in all sorts of ways. It only measures certain types of transactions that occur within the formal economy, so for example a million pound personal injury claim would contribute to GDP growth whereas unpaid community work wouldn't. 

A Green government would look to different types of economic indictors as barometers for prosperity. For example, it would consider increased growth and technological advancements in priority industries such as renewable energy as a sign of success. On the other hand, growth in sectors that damage our health and social fabric would be seen as a bad thing.

Therefore the key to a Green economy is sustainability, which would always take precedence over growth. The definition of a sustainable economy is one that meets society's current needs without compromising the ability of future generations to meet their needs.

Why solar costs will fall another 40% in just two years

Why solar costs will fall another 40% in just two years | Zero Footprint |
Even the world's biggest fossil fuel producers recognise that solar is winning the cost war. In the next two years, solar costs will fall even further - as much as 40 per cent. Here's how.


It’s been one of the big themes at the World Energy Future Conference here in Abu Dhabi. Solar, and other technologies such as wind power, are no longer more expensive than traditional fossil fuels in many parts of the world. Indeed, they are cheaper.


A day earlier, the International Renewable Energy predicted that solar costs would fall substantially in coming years, underlying its competitiveness with fossil fuels. If government policy makers did not understand this, IRENA said, then they risked making bad decisions about their energy future.


While much of the cost reduction over the last 5-10 years has resulted from polysilicon price reductions, future cost reductions will necessarily come from non panel related balance of system costs.


Inverter and racking cost are also declining.

Installation costs will fall by one third in the US.

Sales/Customer Acquisition Cost will fall even further.


Daniel LaLiberte's insight:

As renewable energy continues to grow even cheaper, fossil fuel costs are either going to go up because of reduced supply of cheaply exploited resources, or fall due to collapsing demand, or some of both.  Fossil fuels ought to cost enough to pay for the clean up all the CO2 and other pollution that results from burning. But regardless, the encroaching competition from renewable energy will eventually catch up and "clean up".  The question is not whether it will happen but how soon?

Sustainability challenged as many renewable resources max out

Sustainability challenged as many renewable resources max out | Zero Footprint |

The days of assuming natural resources can be swapped in and out to solve shortages - corn for oil, soy for beef - may be over. An international group of scientists demonstrate that many key resources have peaked in productivity, pointing to the sobering conclusion that "renewable" is not synonymous with "unlimited."


For Jianguo "Jack" Liu, who is director of MSU's Center for Systems Integration and Sustainability, this is strong reason for integration—to approach sustainability problems holistically, rather than searching for a "one for one" substitution to offset shortages.


"People often talk about substitution. If we run out of one resource, we just substitute another. But if multiple resources are running out, we've got a problem," Liu said.

Daniel LaLiberte's insight:

Bio-renewables have a recovery rate limitation, but wind and solar energy are limited only by how much we can collect at once, which is thousands of times more than we currently need.

Deutsche Bank Predicts Solar Grid Parity In 80% Of Global Market By 2017

Deutsche Bank Predicts Solar Grid Parity In 80% Of Global Market By 2017 | Zero Footprint |

Investment bank Deutsche Bank is predicting that solar systems will be at grid parity in up to 80 per cent of the global market within 2 years, and says the collapse in the oil price will do little to slow down the solar juggernaut.

“We believe the trend is clear: grid parity without subsidies is already here, increasing parity will occur, and solar penetration rates are set to ramp worldwide,” Shah notes.


In the US, solar demand is expected to jump five fold to 16,000MW in 2016, making it the biggest market in the world ahead of China (which is expected to be about 13,000MW a year).


Daniel LaLiberte's insight:

The rapid acceleration of solar energy deployment has already started, and grid parity means there's no stopping it now.

Peru lifts renewable energy target to 60% by 2025, aims for 100% long term

Peru lifts renewable energy target to 60% by 2025, aims for 100% long term | Zero Footprint |
Peru is looking to lift its renewable energy target from 46% to 60% over the next 10 years, and use solar - not coal - to solve energy poverty.


The plans include a program to install 500,000 solar arrays to lift the access to electricity to 99 per cent from the current level of 92 per cent by 2019. Most of these are in rural areas. Of course, they see no need to use coal to end energy poverty.

In the longer term, Peru says it aims to substitute gas with a mix of renewables including hydro, solar, wind, and geothermal. It is estimated that Peru has some 3,000GW of geothermal energy potential, but this has yet to be exploited.

Daniel LaLiberte's insight:

Increasingly, "no need for coal" will lead to the demise of that part of the fossil fuel industry.

World Bank to ditch coal for clean energy

World Bank to ditch coal for clean energy | Zero Footprint |

The World Bank will invest heavily in clean energy and only fund coal projects in “circumstances of extreme need” because climate change will undermine efforts to eliminate extreme poverty, says its President Jim Yong Kim.

Kim was backed by Rachel Kyte, World Bank group vice president and special envoy for climate change. “It will only be in circumstances of extreme need that we would contemplate doing coal again. We would only contemplate doing [it] in the poorest of countries where their energy transition as part of their low-carbon development plan means that there are no other base load power sources available at a reasonable price,” she said.

“The bank has taken an important first step in essentially stopping its support for coal-fired power plants, but climate change is caused by more than just coal,” said Stephen Kretzmann, director of Oil Change International. “The vast majority of currently proven fossil fuel reserves will need to be left in the ground if the world is to avoid dangerous climate change, but last year the bank provided nearly $1 billion in support for finding more of these unburnable carbon reserves.”

Recycling Opens the Door to a Circular Economy

Recycling Opens the Door to a Circular Economy | Zero Footprint |

Recycling is critically important, but it's only one part of a larger, globally emergent environmental paradigm known as the Circular Economy. 


The name is literal, referring to an industrial economy that goes far beyond recycling and which only creates secondary materials from primary ones. The Circular Economy is restorative by intention and based on eliminating material loss. To that end, it employs renewable energy, minimizes or eliminates toxic chemicals and avoids waste through careful design. It looks closely at how we design, make, sell, re-use and recycle products to determine how to secure the maximum value, both in use and at the end of their life.


With this all-encompassing approach, the Circular Economy aims to eradicate waste -- not just from manufacturing processes but systematically, throughout the life cycle of products and their components. Consciously designing durable goods to be restorative will keep components and products in longer use, and ensure that biological materials can re-enter the biosphere at the end of their lives.


Can it work? "Towards the Circular Economy," a 2014 report from the World Economic Forum, the Ellen MacArthur Foundation and McKinsey & Company, estimates that shifting to this model could add over $1 trillion a year to the global economy by 2025 and create 100,000 new jobs within the next five years if companies put their energies behind developing circular supply chains and increase the rate of recycling, reuse and remanufacture.

Biodiversity for a Livable Climate - Conference 2014

Biodiversity for a Livable Climate - Conference 2014 | Zero Footprint |

Promoting the power of nature to remove excess carbon from the atmosphere where it does untold damage, and restore it to the soils where it supports abundant life and helps reverse global warming.


Our primary urgent goal in the face of widespread breakdown in addressing climate change is to further the understanding necessary to embark on the global regeneration process made possible by enabling the forces of biology. Collectively we will present affordable strategies for eco-restoration that local, national and international governments, agencies, communities and individuals may rapidly implement in order to reverse global warming.


There is a way, which has yet to take its rightful place at the heart of the climate debate: the capacity of the natural world to actively remove carbon dioxide from the atmosphere and store it in soils worldwide.


The biosphere is a powerful geological force. While it is not yet widely understood, the life force has been terraforming the earth for the past 3.5 billion years, from vast rock formations to an oxygen atmosphere to soils and weather and everything in-between. Forces of living systems, managed for healthy biodiversity and natural cycles, will capture prodigious amounts of carbon dioxide. If we set up favorable conditions, nature will store greenhouse gases in complex and stable biomolecules in soils, the largest terrestrial carbon sink on the planet, as it has done for eons.


We already have the knowledge and experience to move ahead confidently with all due haste. Scientists and practitioners of eco-restoration have decades of experience, repeatedly having demonstrated dramatic successes in bringing dying lands back to life in only a few years, regenerating ecosystems such as dry grasslands, humid jungles, and temperate forests.


To accomplish this on a global scale would not only address a rapidly deteriorating climate, but restore flourishing habitats for the millions of species that we depend upon across the world, and bring untold benefits, including food production and economic security, to people everywhere. Best of all, it is low-tech and low-cost – and when given a chance, the biodiverse life in the world’s soils will do 99% of the work.

Why dedicating land to bioenergy won't curb climate change

Why dedicating land to bioenergy won't curb climate change | Zero Footprint |

A new WRI paper finds bioenergy can play a modest role using wastes and other niche fuelstocks, but recommends against dedicating land to produce bioenergy. The lesson: do not grow food or grass crops for ethanol or diesel or cut down trees for electricity.

Even modest quantities of bioenergy would greatly increase the global competition for land. People already use roughly three-quarters of the world’s vegetated land for crops, livestock grazing and wood harvests. The remaining land protects clean water, supports biodiversity and stores carbon in trees, shrubs and soils—a benefit increasingly important for tackling climate change. The competition for land is growing, even without more bioenergy, to meet likely demands for at least 70 percent more food, forage and wood.

Some institutions have called for producing 20 percent of human energy needs from bioenergy of all sorts by 2050. That would require an amount of biomass equal to all the plants harvested annually across the entire world today: all the crops, crop residues, wood and grasses eaten by livestock. The world does not have the room.

Solar Cells Offer an Alternative

The good news is that standard solar cells available today can generate more than 100 times as much usable energy per acre (hectare) as bioenergy even using optimistic projections for bioenergy’s future. When used with electric engines in cars with more efficient batteries, solar benefits can rise to 200 or 300 times the efficiency biofuels. And unlike bioenergy, solar energy works great in deserts and on rooftops without competing for fertile land.

Daniel LaLiberte's insight:

The solar energy we can derive from plants is such a small fraction of what we can get more directly, without completing for fertile land, that there should be no question how to proceed.  There may be value in storing energy in biofuels, but we'd have to do that much more efficiently.

5 Reasons the Future of Clean Energy Investing Looks Stronger than Ever

5 Reasons the Future of Clean Energy Investing Looks Stronger than Ever | Zero Footprint |

1. Clean energy investment has been – and continues to be – on the rise


Recent buzz around clean energy investment has centered on a new Bloomberg New Energy Finance (BNEF) report detailing the global clean energy industry’s strong 2014 investment results, results that even “beat expectations”. 


2. Wind and solar energy costs continue to drop precipitously


According to Lazard, the levelized cost of energy (LCOE) for solar and wind energy have decreased 78 percent and 58 percent, respectively, since 2009.


As costs of wind, solar, and other forms of clean energy decline, improved economic viability will likely lead to growth in clean energy investment.


3. Clean energy investment in the developing world is growing explosively – and just getting started


As costs drop, renewables promise to catch and become even more desirable in the developing world. 


Among the many reasons clean energy resources are ideal for developing nations are:


* Many of these countries lack infrastructure for large, traditional power plants; and, distributed generation (like rooftop solar) requires far less infrastructure;

* Many developing countries are at sunny, equatorial latitudes, which are ideal for solar power; and

* In regions characterized by energy poverty, upscaling usage of renewables is far less politically sensitive because there are not established fossil-fuel lobbies fighting to preserve the status quo.


4. Promising policy advances for clean energy integration


U.S. and global policy momentum is trending toward the creation of a global economy that is increasingly favorable toward renewable energy integration.


5. Countries around the world are already seeing the benefits of clean energy adoption


Positive experiences from countries pursuing clean energy integration prove the viability of upscaling renewables, as well as provide motivation and blueprints for others to follow. 


While 2014 was an especially strong year for clean energy investment, it was not an outlier so much as an indication of what is to come. Investors, take note: clean energy has clearly been trending upward at an impressive rate. Money has and will continue to be made through the industry in 2015 and onward.

Citi: Battery storage to hasten demise of fossil fuels

Citi: Battery storage to hasten demise of fossil fuels | Zero Footprint |

Investment bank says wide deployment of battery storage will hasten the demise of fossil fuels and utilities that remain focused on centralised generation. It tips rapid fall in costs and a $400bn storage market by 2030.

The issue is therefor rapidly moving beyond those with a narrow focus on utilities and energy markets, it is now part of mainstream financial thinking, and because of that will have a profound influence on capital flows across the globe.


And on the technology front, the increased penetration of electric vehicles should continue to push down the cost of batteries for cars with parallel effects for energy systems battery costs.


It cited projects such as Tesla’s Giga-factory in Nevada 

with plans for 2020 battery production (in GWh) from that plant alone to exceed today’s global production. Over and above this, a number of independent companies all have ambitious commercial plans.

“The more they grow in customer numbers and partnerships, the more likely it is that battery storage costs will be declining,” the analysts write.

Ocean warming now off the charts

Ocean warming now off the charts | Zero Footprint |

The big climate news last week was NOAA and NASA announcing that 2014 was the hottest year on record, breaking the highs of 2005 and 2010. But the bigger story got buried: Global warming has continued unabated in recent years.

Remember, more than 90 percent of human induced planetary warming goes into the oceans, while only 2 percent goes into the atmosphere, so small changes in ocean uptake can have huge impact on surface temperatures. That’s a key reason surface temperatures haven’t appeared to warm as fast as many had expected in the past ten years — although ocean warming has sped up, and sea level rise has accelerated more than we thought , and Arctic sea ice has melted much faster than the models expected, as have the great ice sheets in Greenland and Antarctica


But here’s where the media’s sometimes single-minded focus on one statistic — the hottest year on record — misses the real story from the latest scientific data and analysis. The human-caused rise in surface air temperatures never paused, never even slowed significantly. And that means we are likely headed toward a period of rapid surface temperature warming.

Cradle-to-cradle design - Wikipedia, the free encyclopedia

Cradle-to-cradle design - Wikipedia, the free encyclopedia

Cradle to Cradle design (also referred to as Cradle to Cradle, C2C, cradle 2 cradle, or regenerative design) is a biomimetic approach to the design of products and systems. It models human industry on nature's processes viewing materials as nutrients circulating in healthy, safe metabolisms. It suggests that industry must protect and enrich ecosystems and nature's biological metabolism while also maintaining a safe, productive technical metabolism for the high-quality use and circulation of organic and technical nutrients.

Put simply, it is a holistic economic, industrial and social framework that seeks to create systems that are not only efficient but also essentially waste free. The model in its broadest sense is not limited to industrial design and manufacturing; it can be applied to many aspects of human civilization such as urban environments, buildings, economics and social systems.


In 2002, Braungart and William McDonough published a book called Cradle to Cradle: Remaking the Way We Make Things, a manifesto for cradle to cradle design that gives specific details of how to achieve the model.


The Cradle to Cradle model can be viewed as a framework that considers systems as a whole or holistically. It can be applied to many aspects of human society, and is related to Life cycle assessment. See for instance the LCA based model of the Eco-costs, which has been designed to cope with analyses of recycle systems. The Cradle to Cradle model in some implementations is closely linked with the Car-free movement, such as in the case of large-scale building projects or the construction or redevelopment of urban environments. It is closely linked with passive solar design in the building industry and with permaculture in agriculture within or near urban environments. An earthship is a perfect example where different re-use models are used, cradle to cradle and permaculture.

How it took just one generation to stuff the planet

How it took just one generation to stuff the planet | Zero Footprint |

In just a single life-time, unchecked human activity has put life on Earth in peril, according to two new research papers. 

The first paper identifies nine planetary processes that are indicators of the health of Earth, and regulate the stability and resilience of the planet.

In four of these, the boundaries have already been crossed – the loss of biodiversity through an unprecedented rate of species extinction, and the overuse of fertilizers such as phosphorus and nitrogen already put those markets in the “red zone”.

Australian scientist Will Steffen has also led research in the creation of a “dashboard” that document the  “Great Acceleration” in human activity since the 1950s. And it concludes that the main driver is the global economic system.

Steffen says there is growing confidence that things can be done differently, and rampant economic growth can be disconnected from rises in greenhouse gases – this will happen with the growing adoption of clean energy, and the electrification of transport. And scientists know that more people can be fed with less phosphorous and nitrogen.


Steffen says the climate talks in Paris this year will be crucial to address how many of these issues are addressed, particularly in relating to climate. And he says his graphs point to the issue of equity – the developed nations with just 18 per cent of the population account for 70 per cent of the economic growth most of the changes documented in his dashboard.

“Have we stuffed the planet yet? Not entirely,” Steffen says. “But there is a very high risk we will in coming decades if we don’t change direction.”

Daniel LaLiberte's insight:

Note that the driving force of our problems is not population growth but unsustainable economic growth.   A small percentage of the population, namely us, accounts for most of the economic activity that results in the detrimental consequences.


We know how to do everything sustainably.  We know how to repair the damage already done.  The question is only how fast will we change direction and act responsibly to avoid the worst of the problems ahead?

Poor Nations Go for Solar, Wind at Twice the Pace of Rich Ones

Poor Nations Go for Solar, Wind at Twice the Pace of Rich Ones | Zero Footprint |
Emerging markets are installing renewable energy projects at almost twice the rate of developed nations, a report concluded


The boom in renewables is often made for economic reasons, Ethan Zindler, a Washington-based Bloomberg New Energy Finance analyst, said in an interview. An island nation like Jamaica, where wholesale power costs about $300 a megawatt-hour, could generate electricity from solar panels for about half as much. Similarly, wind power in Nicaragua may be half as expensive as traditional energy.


“Clean energy is the low-cost option in a lot of these countries,” Zindler said by telephone. “The technologies are cost-competitive right now. Not in the future, but right now.”


The International Energy Agency said Oct. 13 that renewable energy and hydropower will supply almost half of the generation required for growth in Africa through 2040, as the sub-Saharan economy quadruples. Energy use in that region, up 45 percent since 2000, is expected to climb 80 percent through 2040.

Via Pol Bacquet
Daniel LaLiberte's insight:

So Yes the developing world needs to continue developing, and they will use much more energy than they do now, but it can be mostly renewable, if not entirely so.  


And while the world population may grow by up to 50%, the much larger growth of renewable energy will be fueled NOT by population growth, but by the enormous need to replace 100% of OUR fossil fuels while also reducing the extreme disparity between rich and poor countries.

Soil's large carbon stores could be freed by increased CO2, plant growth

Soil's large carbon stores could be freed by increased CO2, plant growth | Zero Footprint |

Researchers based at Princeton University report in the journal Nature Climate Change that the carbon in soil—which contains twice the amount of carbon in all plants and Earth's atmosphere combined—could become increasingly volatile as people add more carbon dioxide to the atmosphere, largely because of increased plant growth. The researchers developed the first computer model to show at a global scale the complex interaction between carbon, plants and soil, which includes numerous bacteria, fungi, minerals and carbon compounds that respond in complex ways to temperature, moisture and the carbon that plants contribute to soil.

Although a greenhouse gas and pollutant, carbon dioxide also supports plant growth. As trees and other vegetation flourish in a carbon dioxide-rich future, their roots could stimulate microbial activity in soil that in turn accelerates the decomposition of soil carbon and its release into the atmosphere as carbon dioxide, the researchers found.

This effect counters current key projections regarding Earth's future carbon cycle, particularly that greater plant growth could offset carbon dioxide emissions as flora take up more of the gas, said first author Benjamin Sulman, who conducted the modeling work as a postdoctoral researcher at the Princeton Environmental Institute.

"You should not count on getting more carbon storage in the soil just because tree growth is increasing," said Sulman, who is now a postdoctoral researcher at Indiana University.

More consumption not necessary for human well-being, says UN report

More consumption not necessary for human well-being, says UN report | Zero Footprint |

Greater food system efficiency and curbs to the expansion of cropland are necessary to prevent the collapse of global ecosystems, says a report presented today (24 January) by the UN at the World Economic Forum in Davos, Switzerland.


The report, by the UN Environment Programme’s science think tank the International Resource Panel (IRP), says that policymakers must break the link between greater resource consumption and human well-being.


The IRP calls on governments to take immediate action to prevent the degradation of land and soils and to carry out measures to regenerate destroyed areas, rather than moving agricultural production to new sites, through deforestation, for example.

“Today’s report shows how Europe is consuming more than its fair share of land, at the expense of other world regions, and suggests that Europe needs to reduce its consumption of cropland by around a third,” read a statement by Friends of the Earth Europe (FOEE), an environmental campaign group.

The United States can reduce greenhouse gas emissions by 80 percent by 2050, using existing or near-commercial technologies, according to researchers with the Deep Decarbonization Pathways Project. The study analyzed scenarios with four types of decarbonized electricity: renewable energy, nuclear energy, fossil fuel with carbon capture and storage, and a mixed case.


The energy efficiency of buildings, transportation, and industry would need to increase through the use of smart materials and energy-efficient designs, and vehicles will need to be fueled with electricity generated from wind, solar, or nuclear, as opposed to coal, the researchers said. They project the net costs would be on the order of 1 percent of gross domestic product per year.

Daniel LaLiberte's insight:

If we can do this, at a cost of only 1% GDP per year, that's good news, but then we can easily do a lot more, a lot sooner.  We really do need to cut emissions all the way down to 0 in only a couple decades, and we need to go further and sequester everything we have already emitted, and somehow cool the oceans where most of the excess heat is being stored.

Why it pays to join the circular economy - Forum:Blog

Why it pays to join the circular economy - Forum:Blog | Zero Footprint |

The circular economy in developing countries will explode over the coming decade, creating up to 7 million new jobs in China alone, writes Danish MP Ida Auken.


We all know that the current linear economic model is not sustainable. Materials are extracted, manufactured into products and then discarded into landfill – it’s a system that wastes valuable resources, causes environmental damage and will make it near impossible to satisfy the demands of the 3 billion new consumers in developing nations, who are expected to join the middle class by 2030.


The concept of the circular economy is about decoupling growth from resource consumption – and maximizing the positive environmental, economic and social effects. It’s about designing products so that they are easier to reuse or recycle, like Timberland’s Earthkeeper shoes. It’s about making sure that every product ingredient is biodegradable or fully recyclable, like the chemicals company that has replaced fossil-fuel feedstocks in their production methods. It’s about maximizing useful product life by repairing or remanufacturing, like Caterpillar’s parts-refurbishing programme.


There are those already catching on to this competitive advantage. Take, for example, anyone involved in the World Economic Forum and Young Global Leader’s first annual Circular Economy Awards, which recognizes ideas leading the transformation towards a truly restorative industrial economy.

One Solution to Climate Change and Growing Healthier Food Is Right Under Our Feet | Barbara Streisand Blog |

One Solution to Climate Change and Growing Healthier Food Is Right Under Our Feet | Barbara Streisand Blog | | Zero Footprint |

Imagine if we could quickly reduce the threat of climate change and grow healthier crops at the same time, without the sacrifice the coal and oil industry tells us are inevitable! Turns out we can, and the solution is literally right under our feet.


As we know now, too much carbon dioxide (CO2) in our atmosphere is disastrous for our planet. CO2 traps heat and results in the ice caps melting, more extreme weather, sea levels rising and a variety of consequences that will disrupt life as we know it.


Much of the CO2 in the atmosphere (as much as 30 percent) is leaked by industrial farming. Climate scientists tell us there should be no more than 350 parts per million of CO2 in the atmosphere and we are already at 400 ppm. What does this mean? We are racing against the carbon clock to combat climate change.


However... CO2 in the ground, where it naturally occurs, is in fact necessary for fertile soil, and results in healthier and more drought-resistant cropland. We can keep CO2 in the ground through a natural process that traps it in a "carbon sink." That process is organic or "carbon farming."


We all remember learning about photosynthesis in school. Plants manufacture much of their food from sunlight, water and CO2, turning those molecules into food. The CO2 is exchanged with the fungi and bacteria in the soil that need it to make richer soil and, in turn, healthier plants. In doing so, the CO2 is captured in the ground. In this natural ecological barter system, carbon is sequestered, helping plants grow while keeping the soil healthy. Industrial farming literally prevents this underground transaction from happening by releasing the CO2 into the atmosphere.


Organic farms, like the famous Rodale Farming System Trial in Pennsylvania, showed that building up soil carbon has other benefits too. It also acts like a water sponge and helps maintain crop yields when conventionally grown crops are dying of thirst during droughts. Unfortunately, extreme droughts may become the new normal as climate change alters our weather patterns, giving us yet another reason to implement organic farming on a large scale. According to the USDA-funded Marin Carbon Project, the overuse use of insecticides, herbicides and fertilizers also release what is normally sequestered carbon -- adding to the problems of climate change.


The good news is that if humans get out of the way, CO2 can be tucked back in the soil to do good, instead of being trapped in the atmosphere doing harm. A U.N. report noted using carbon sinks through natural farming methods could reduce the carbon in the atmosphere to pre-industrial levels in just 50 years!


The critics say we need industrial agriculture to feed the growing population of the world. We're told that we cannot go back to natural, regenerative, organic farming as the way we grow our food. In short, this isn't true.


The world has less of a food problem, than a food distribution problem, and studies show that yields are comparable between the two methods when done to scale. The United Nations Environment Program points out that "in the United States 30 percent of all food... is thrown away each year [and] about half of the water used to produce this food also goes to waste, since agriculture is the largest human use of water."
