“This figure shows concentrations of carbon dioxide in the atmosphere from hundreds of thousands of years ago through 2013, measured in parts per million (ppm). The data come from a variety of historical ice core studies and recent air monitoring sites around the world. Each line represents a different data source.” - United States Environmental Protection Agency ... Read more about Global Atmospheric Concentrations of Carbon Dioxide Over Time

So much for China's change of heart when it comes to taking care of the environment.

The Chinese government recently approved construction on nine of 40 large-scale plants that will convert coal into synthetic natural gas — a process that produces seven times more greenhouse gas emissions than regular natural gas production, and uses as much as 100 times the water as shale gas extraction, according to a new study by Duke University. ...

Algae-derived biofuel can reduce life cycle CO2 emissions by 50 to 70 per cent compared to petroleum fuels, according to a new peer-reviewed paper published in Bioresource Technology journal.

As reported in Scienceblog, the study, which is the first to analyse real-world data from an existing algae-to-energy demonstration scale farm, shows that the environmental and energy benefits of algae biofuel are at least on par, and likely bett ...

Total vehicle miles traveled (VMt) and VMt per capita declined slightly from 2007 to 2010 (-1% and -3.2%, respectively), though both increased compared to 2009 (Figure 34). Greenhouse gas emissions from transportation dropped by a much wider margin, with a ten percent drop in per capita emissions between 2007 and 2010, and a continued improvement since 2009 in both overall transportation emissions (-0.3%) and per capita transportation emissions (-1.1%).
