Many countries have begun the readiness process, but they have had little incentive to see it through to completion. Lloyd Gamble, the Senior Forest Carbon Program Officer for WWF-US, says the new framework offers both an incentive to move forward and clarity on how to proceed. "Tropical forest nations can now move forward and engage in REDD+ with a clear understanding of what they need to deliver in order to receive valuable performance-based payments for the conservation of their tropical forests,” he says.

The development and deployment of cleaner energy technologies have become globalized phenomena. Yet despite the fact that energy-related goods account for more than ten percent of international trade, policy makers, academics, and the business community perceive barriers to the global diffusion of these emerging technologies. Experts point to problems including intellectual property concerns, trade barriers, and developing countries' limited access to technology and funding.

"Climate change is only half of the story," said Raymond, who also is an associate professor of political science at Purdue. "We need to consider how different societies are threatened by these physical changes in unique ways. Impoverished areas have fewer resources to deal with environmental stress, while wealthy areas have a greater amount of infrastructure that could be lost, and areas with larger populations have more lives at stake."

Democrats blame record drought. Republicans blame Obama. But one thing both parties agree on is that food prices are going up. In his acceptance speech at last week's GOP convention, Mitt Romney openly mocked tackling climate change as the opposite of helping working families, yet pointed to food prices in his long list of ongoing concerns: "Food prices are higher. Utility bills are higher, and gasoline prices, they've doubled," he claimed.

The most recent round of UN climate negotiations ended last month in Warsaw, and the outcome was familiarly inconclusive: Nations agreed to keep negotiating and making voluntary efforts to reduce emissionsof greenhouse gases. After nineteen years of negotiations little has changed. Or has it?

California’s landmark renewable energy policy, the Renewables Portfolio Standard (RPS), establishes a clear blueprint for clean energy investment in the short-run: by 2020, all utilities are required to source 33 percent of their retail electricity sales from renewables. The big question now is what happens after that? What role should renewables play in California’s long-term goal to reduce greenhouse gas emissions 80 percent below 1990 levels by 2050? Read more

Energy efficiency is particularly critical in affordable housing developments, says Jeremy Hays, Chief Strategist for State and Local Initiatives at Green For All, a sustainability advocacy group with offices in Oakland and Washington, D.C. According to Hays, apartment buildings built before 1970 use 55 percent more energy than those built after 1990, while low-income residents spend 400 percent more of their monthly income on utility bills than the average American.

Measuring the greenhouse gas (GHG) intensity of biofuels has become increasingly important in recent years. Studies have shown a significant amount of variation in biofuels made from different feedstocks. In some cases, biofuels are only marginally better than fossil fuel counterparts. In other cases, there are significant improvements in GHG performance.

Last week BBC News published the first results from a year-long project launched at London’s Science Museum in March, 2013. The study found that people were more likely to take positive steps towards reducing climate change when presented with action steps in game form rather than in the midst of a deluge of gloomy facts and figures.
