Reuters: Biofuel producers will be subject to rules regulating carbon emissions, a U.S. appeals court ruled on Friday, in a decision hailed by environmental groups. The U.S. Court of Appeals for the District of Columbia Circuit vacated a three-year deferral put in place in 2011 by the Environmental Protection Agency (EPA) that temporarily exempted paper and wood product manufacturers and ethanol producers from curbing the release of greenhouse gases. The EPA wanted to further study how much of the emissions...
Europes carbon credit oversupply could worsen

Energy Live: The oversupply of carbon credits in the European Unions carbon trading scheme could worsen. Thats the view of ratings agency Fitch in response to the MEPs` decision to temporarily withdraw 900 million permits in the EUs Emissions Trading System (ETS) last week. Giving its verdict on the European Parliaments vote to hold back carbon credits, Fitch suggested that in the short term is likely to push their prices up if the move gains traction but wont kill off coal power. It pointed...

Reuters: The United States and China, the world's top emitters of greenhouse gases, agreed to five initiatives on Wednesday to cut carbon output from the largest sources, including heavy duty vehicles, manufacturing and coal-fired plants, the State Department said. The US-China climate change working group, which officials from both countries formed in April, will work with companies and non-governmental groups to develop plans by October to carry out the measures aimed at fighting climate change and cutting...

Trees Using Water more efficiently Due to Carbon Dioxide Increase
2013-07-11 10:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Trees are using water more efficiently now than they did two decades back, according to a new study from Harvard University and the U.S. Forest Service. Researchers said that increased levels of carbon dioxide along and lower levels of water in many parts of the world have increased the efficiency of water usage in trees. Plants use carbon dioxide from the atmosphere via a process called photosynthesis, where they lose water through leaves. The ratio of water loss to fixed carbon is important...

In the Greenhouse: Forests Get More Water Efficient as Carbon Dioxide Levels Rise
2013-07-11 04:46:00| Climate Ark Climate Change & Global Warming Newsfeed
Time: The response to climate change has two sides: mitigation and adaptation. Mitigation means reducing greenhouse gases in an effort to slow the pace of warming and lessen its effects. Adaptation means responding to those effects, working to blunt climate change as it unfolds. It`s offense versus defense. Mitigation gets most of the attention because it mostly involves changing the way we use energy, something that we spend trillions of dollars on. Such shifts can have a huge impact on the economy--for...
