New analysis finds Asia produces twice as much mercury emissions as previously thought

Green Car Congress

While its increased burning of coal was known to exacerbate mercury emissions and air pollution, the MIT-led team estimates that Asia produces more than double the mercury emissions previously estimated. Given the pollution in China and India and increased use of coal, it does make sense. It was higher than we expected.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

Congress has provided hundreds of billions of dollars to speed the deployment of clean-energy technologies. As legislation worked its way through Congress, Jenkins’s team provided elected officials, staffers, and stakeholders with a running tally of the possible trade-offs and payoffs in emissions, jobs, and economic growth.

Perspective: Shoddy Environmental BookkeepingBiofuels and Indirect Land Use Change

Green Car Congress

The basic idea behind ILUC is that biofuels use crops that might otherwise go to traditional uses, such as animal feed. Indirect effects analysis concludes that a new coal-burning power plant will supply the lost electricity, with a huge resulting GHG release. The polluter does not pay. Finally, let’s look at a policy example.

$12+M awarded to 4 projects seeking to design crops with ability to fix their own nitrogen; no artificial fertilizers

Green Car Congress

Four teams of researchers in the United States and the United Kingdom recently were awarded more than $12 million to begin a program of novel research to revolutionize current farming methods by giving crops the ability to thrive without using costly, polluting artificial fertilizers. NSF solely awarded one of the four projects.

CAS researchers propose decoupling gasification reactions for greater control and optimized outcomes

Green Car Congress

Gasification is emerging as a core technology for the production of chemicals and cleaner power, and refers to a process for converting solid fuels, including coal, biomass, and wastes, into either fuel gas (containing CH 4 and some N 2 usually) or syngas (containing mainly H 2 and CO) for subsequent conversion into fuels and chemicals.

Berkeley Lab team building new total cost of ownership model for fuel cells; intrinsic and external benefits

Green Car Congress

Our model will give an idea of the big picture savings, and whether there are incentives that can be provided to make sure the savings are captured. For example, are the benefits of fuel cells the same in Washington state, which gets much of its power from hydroelectricity, as in West Virginia, which is dominated by coal?

NASA GISS Study Finds That Methane Has an Elevated Warming Effect Due to Interactions With Aerosols

Green Car Congress

As a result of their findings, published in the 30 October issue of the journal Science , the authors argue that assessments of multigas mitigation policies, as well as any separate efforts to mitigate warming from short-lived pollutants, should include gas-aerosol interactions. —Drew Shindell. —Drew Shindell.
