United States Carbon Emissions: An Interactive Heat Map & New Research

United States Carbon Emissions: An Interactive Heat Map & New Research | Sustain Our Earth | Scoop.it

When it comes to carbon emissions, don’t blame big cities -- blame the suburbs, says a new study from the University of California, Berkeley. The study, released Monday, found that population-dense cities contribute less greenhouse-gas emissions per person than other areas of the United States. However, these cities’ suburbs are so damaging to the environment that they effectively wipe out any climate benefits. The study will be published in science journal Environmental Science & Technology.

 

Using dozens of variables, researchers found that greenhouse-gas emissions -- largely from cars, trucks and other vehicles -- in the suburbs account for about 50 percent of all household emissions in the nation, even though less than 50 percent of the population lives in these areas.

Wooden Skyscrapers: A New Level of Sustainability?

Wooden Skyscrapers: A New Level of Sustainability? | Sustain Our Earth | Scoop.it

A new breed of high-rise architecture is in the process of being born, thanks to the collaborative efforts of modern design pioneers. Envisioned as the best sustainable option for meeting world housing demands and decreasing global carbon emissions, wooden mega-structures are now one step closer to becoming a reality.


“Big Wood,” a conceptual project to the eVolo 2013 Skyscraper Competition, builds on the premise that wood, when harvested responsibly, is one of the best tools architects and engineers have for reducing greenhouse gas emissions and creating healthy communities. Aspiring to become one of the greenest skyscrapers in the world, Big Wood challenges the way we build our cities and promotes timber as a reliable platform to support tomorrow’s office and residential towers...

Fascinating place. Must of been a lot of wood to be created.

Bubba Muntzer's comment, May 13, 2013 11:44 AM
It takes around 30 years for a seedling to grow into the kind of wood that can be used in construction. A little maintenance is required during that period. Meanwhile it's soaking up CO2 and making oxygen. The only industrial processes required are to cut it down and cut it into boards and 2 x 4s. If you stagger your planting you have an endless supply.

Infographic: Companies unprepared to address resource scarcities

Infographic:  Companies unprepared to address resource scarcities | Sustain Our Earth | Scoop.it

New research shows that many businesses around the world won’t start planning until 2018. Is this too late?

Despite widespread warnings of resource scarcity over the next few decades, a significant proportion of global businesses are not prepared to address the predicted shortfall, according to new research by Carbon Trust.
The U.K.-based organization’s survey of 475 executives in the U.S., Brazil, China, Korea and the U.K. revealed while a majority acknowledged that their companies would have to charge more for their products and services as a result of resource constraints, 43 percent are not monitoring risks posed by incidents such as energy price increases and environmental disasters. Over 50 percent have not developed goals to reduce their company’s consumption of water, waste production or carbon emissions...

The earth is bounded and its resources finite. Hopefully it will be a proactive and not reactive decision to do what is critical to the sustainability of the earth. Spread the word....

Southern Ocean is the largest ocean carbon sink soaking up about 40% of the mankinid's CO2 absorbed by the oceans, staudy finds

(Reuters) - From giant whirlpools to currents 1,000 km wide, scientists said on Monday they have uncovered how vast amounts of carbon are locked away in the depths of the Southern Ocean, boosting researchers ability to detect the impact of climate change.

 

Oceans curb the pace of climate change by absorbing carbon dioxide emissions from burning fossil fuels. The Southern Ocean is the largest of these ocean carbon sinks, soaking up about 40 percent of mankind's CO2 absorbed by the seas.

 

But until now, researchers were unsure what mechanisms were involved because of the remoteness and sheer size of the Southern Ocean.

 

"By identifying the mechanisms responsible for taking carbon out of the surface layer in the ocean, we're in a much better situation to talk about how climate change might impact that process," said oceanographer Richard Matear, one of the authors of the Southern Ocean study published in the journal Nature Geoscience.

 

The team of British and Australian scientists found that currents that take carbon from the surface to the depths occur at specific locations, not uniformly across the ocean as previously thought.

 

They found that a combination of winds, currents and whirlpools create conditions for carbon to be drawn down into the deep ocean to be locked away for decades to centuries. Some of the plunging currents were up to 1,000 km (600 miles) wide.

 

In other areas, currents return carbon to the atmosphere as part of a natural cycle.

Green and Healthy Buildings: monitoring consumption & ecology in the built environment

Green and Healthy Buildings: monitoring consumption & ecology in the built environment | Sustain Our Earth | Scoop.it

According to the United Nations Environment Programme, buildings account for approximately 40 percent of worldwide energy use and are responsible for 30 percent of greenhouse gas emissions. They also play an important role in the health and wellbeing of those who inhabit them each day.

The mass of information about what makes a building green tends to concentrate on new and innovative designs that create beautiful photo spreads. While such examples are inspiring, they make up a very small percentage of all buildings in operation.

Green Buildings Alive is an environmental initiative aimed at collecting and sharing data on existing buildings between 10 and 60 years old. The data is collected from office towers in Australian Central Business Districts (CBDs) and shared on a public website.

How Urban Farming can Transform our Cities & our Agricultural System

How Urban Farming can Transform our Cities & our Agricultural System | Sustain Our Earth | Scoop.it

As concerns mount over the accessibility and quality of meals in cities, urban agriculture is becoming a practical solution to give communities more choice—all while helping address greenhouse gas emissions from centralized agriculture.
With more than 80 percent of the American population living in metropolitan centers, urban farming has the ability to dramatically enhance economic growth, increase food quality and build healthier communities.
