The calculated relative amounts of well-to-wheels emissions of greenhouse gases from eight different energy sources are shown in the table below. These results indicate that coal and oil are the energy sources leading to most emissions, and that hydro, wind, and nuclear are the energy sources leading to least emissions.
Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.

Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The burning of coal releases more carbon dioxide than other fossil fuels, as well as comparatively high levels of other pollutants, including sulfur dioxide, nitrogen oxides, and particles such as ash.
The European Community’s air pollutantemission inventory report released by the European Environment Agency finds that in 2007, sulphur oxides (SO x ) emissions were down by 72 % from 1990 levels. EU-27 emissions of all four pollutants were lower in 2007 than in 2006.
Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. —Mark Jacobson.
In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. But the rapid reduction of PM 2.5
In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. emissions are less important because of the low contribution of light duty vehicles to national PM 10 and PM 2.5

in 2030 even if India were to comply with its existing pollution control policies and regulations. However, aligning sustainable development policies to the implementation of advanced emission control technologies could provide NAAQS-compliant air quality to about 85% of the Indian population. levels by 20-30% over the next five years.

My favorite part of this next CicLaVia is t he Bike Parade coming from my friends at Greenpeace and Sierra Club which they’re calling ROLL AGAINST COAL.
In addition to keeping anthropogenic CO 2 out of the atmosphere, this technology will lead to benefits and trade-offs for air pollution, according to a new report from the European Environment Agency (EEA). The report shows that while CCS may have an overall positive effect on air pollution, emissions of some pollutants may increase.

The proposed rulemaking establishes separate standards for natural gas and coal plants. Background. In the decision in Massachusetts v. Earlier post.)
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).
Plastics are on track to contribute more greenhouse gas emissions than coal plants in the US by 2030, according to new report by Beyond Plastics, a nationwide project based at Bennington College in Vermont.

The study’s findings highlight the importance of considering exposures—especially the proximity of emissions to people—when evaluating environmental health impacts for EVs, the team said. For EVs, combustion emissions occur where electricity is generated rather than where the vehicle is used. 90% is from coal.
A new report from the European Environment Agency (EEA) warns that the health of Europe’s most vulnerable citizens remains disproportionately affected by environmental hazards such as air and noise pollution and extreme temperatures, especially in Europe’s eastern and southern regions, despite overall improvements in Europe’s environmental quality.

Consider this fair and legal warning, world’s largest and most polluting oil company - I’m giving you 10 years to pack up and hit the road. It’s the 2nd biggest product Exxon/Mobil and their pals in the oil, coal and gas industries pump out. Maybe they should just go take their lies and pollution somewhere else.
Total toxic air releases in 2011 declined 8% from 2010, mostly because of decreases in hazardous air pollutant (HAP) emissions, even while total releases of toxic chemicals increased for the second year in a row, according to the US Environmental Protection Agency (EPA) annual Toxics Release Inventory (TRI) report published today.
