NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

New NASA satellite images released this week demonstrate the reduction of air pollution across the US. Nitrogen dioxide is one of the six common pollutants regulated by the US Environmental Protection Agency (EPA) to protect human health. It’s also a good proxy for the presence of air pollution in general.

EPA report shows progress in reducing urban air toxics across US; 50% reduction from mobile sources since 1990

Green Car Congress

The US Environmental Protection Agency (EPA) released the Second Integrated Urban Air Toxics Report to Congress—the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics (also referred to as hazardous air pollutants or HAPs).

MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

BNEF: Oil price plunge to have only moderate impact on low-carbon electricity development, but likely to slow EV growth

Green Car Congress

With wind and even solar power increasingly competitive with coal and natural gas without subsidies, with many utilities needing to meet renewable portfolio standards, and with new EPA rules forcing coal plant retirements, the impact of lower oil prices on renewable energy in the US is expected to be insignificant.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

This includes the estimates in the 2007 Intergovernmental Panel on Climate Change (IPCC) Assessment, which were based on the best available evidence and analysis at that time. Reducing emissions from diesel engines and domestic wood and coal fires is a no-brainer, as there are tandem health and climate benefits.

House Chairmen Waxman, Markey Release Draft of Energy and Climate Legislation; Among the Many Provisions Are Cap-and-Trade, Harmonization of CAFE and California Vehicle Regulations, and Low Carbon Fuel Standard

Green Car Congress

The draft promotes development of carbon capture and sequestration (CCS) technologies to establish a continuing place for coal in the US energy mix. The draft includes a CCS early demonstration program, incentives for the wide-scale commercial deployment of CCS, and performance standards for new coal-fired power plants.
