To see beyond the hype to urban agriculture's true potential to meet the growing need for healthy food in cities, a recent study published by IOPScience looked at how much food (specifically vegetables) the world's “urban clusters” could actually produce.
Limiting greenhouse gas emissions globally over the next 15 years is both economically feasible and likely to save money, according to a new report from the Global Commission on the Economy and Climate. Between 2015 and 2030, nations are expected to invest roughly $90 trillion in urban, land-use and energy infrastructure, the analysis estimated. Steering those investments toward renewable energy, efficiency improvements, and other low-emission technologies would make that global infrastructure investment more costly, the panel of government and business leaders conceded — but only marginally, adding about $4 trillion overall. But these costs could eventually be offset by the lowered operating costs associated with renewable power, the report suggested. Although they are difficult to quantify, health care savings associated with improved air quality would also offset costs. The biggest challenges for governments will be enacting stronger rules and economic policies that favor low-carbon development, such as cutting the $600 billion that countries currently spend on fossil fuel subsidies. The report highlights the plunging costs of renewable energy — solar technology costs have been cut in half since 2010, for example — and argues that limiting urban sprawl and deforestation are essential steps in combating climate change.
It's a question that's perplexed philosophers for centuries and scientists for decades: Where does consciousness come from? Neuroscientist Christof Koch, chief scientific officer at the Allen Institute for Brain Science, thinks he has an answer.
Researchers have developed a new method for mapping global carbon emissions for individual cities on an hourly basis — a major improvement over previous techniques, which quantified greenhouse emissions less accurately and at coarser scales,...

City leaders have a key role to play at next week’s UN Climate Summit in New York City, which brings together heads of state, mayors, business leaders, and civil society representatives to build momentum towards an international agenda to tackle climate change and build resilience.
The window of opportunity to make meaningful progress in the battle against climate change is shrinking. This is especially true in cities, which are set to gain 1.4 billion people by 2030 and develop trillions of dollars in new infrastructure. Since 70% of global greenhouse gas emissions originate in cities – and these same cities are expected to bear the brunt of climate change impact – any international climate agreement must address urbanization to address the full scope of the challenge.
The Climate Summit places cities high on an agenda packed with different ideas for reducing the world’s emissions. Specifically, municipal leaders will narrow in on three lines of action for low-carbon, sustainable cities: adaptation and resilience; greenhouse gas accounting; and closing the finance gap for sustainable urban development.
Four Dutch engineers have started a revolution. They have developed plan production units the size of a city block and just a few stories high capable of producing the same volume of crops as a large farm.
Chef Dan Barber says the farm-to-table movement that he helped build has failed to support sustainable agriculture on a large scale. To do that, he says in a Yale Environment 360 interview, we need a new way of looking at diverse crops and the foods we eat.
NEW YORK//WASHINGTON (September 16, 2014)—The Global Commission on the Economy and Climate launched a new report, Better Climate, Better Growth: The New Climate Economy, that brings together research by leading global economists showing that the world can achieve economic growth and tackle climate change at the same time.

An RFP issued in February 2014 is paying off in spades for the solar industry with Duke Energy today announcing that it is making a $500 million commitment to solar power in North Carolina. Duke said that the announcement furthers its commitment to renewable energy, helps diversify its energy portfo
