The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
The increase from 2012 to 2013 was due to an increase in the carbon intensity of fuels consumed to generate electricity due to an increase in coal consumption, with decreased natural gas consumption, according to the report. By sector, power plants were the largest source of emissions, accounting for 31% of total US greenhouse gas pollution.
billion barrels of liquid fuels and chemicals from coal and natural gas. GTL fuels are virtually free of sulfur and aromatic compounds and reduce emissions of particulates, nitrogen oxides, carbon monoxide and other pollutants and will improve air quality. Gas to Liquids Life Cycle Assessment Synthesis Report (2004).
A team of atmospheric scientists and environmental engineers from Harvard University and Tsinghua University in Beijing have continuously measured atmospheric CO 2 and carbon monoxide (CO) levels in rural Miyun, about 100 km northeast of Beijing, since November 2004.
This partnership was led by EPA’s Design for the Environment (DfE) Program, in the Office of Pollution Prevention and Toxics, and the National Risk Management Research Laboratory, in EPA’s Office of Research and Development. The Abt authors noted that over time, the manufacturing process for SWCNTs will become much more energy-efficient.
Plug-In Hybrids Are Cleaner (Even on a Coal Grid) [ to top ] This entire section is finally obsolete -- because we now have a definitive study by the Electric Power Research Institute and the Natural Resources Defense Council. But theyve needed definitive proof that PHEVs wont increase pollution. The GREET 1.6
Power and Associates 2004 report ]. Dont PHEVs just shift pollution from gasoline cars to power plants? But its monumentally less pollution , even on the national (half-coal) grid. At the moment, only 2004-2007 Priuses , and to a limited extent, the Ford Escape/Mercury Mariner Hybrids.
A study conducted before and after the 2004 closure of a coal-burning power plant in Tongliang, China, found that children born before the closure had shorter telomeres than those conceived and born after the plant stopped polluting the air. the local coal-burning power plant to improve community health. 2018.01.005.
Several dozen prototypes on 15-passenger van since 2004; now in second generation development; no production plans. Kwong said Toyota is concerned PHEVs might just replace gas problems with more coal emissions, since the cars will require more electricity from utilities. Showed BlueZERO E-CELL PLUS series PHEV concept in December 08.
Experts predict that by the year 2060 global warming, if left unchecked, could result in a temperature rise of seven degrees Fahrenheit higher than temperatures before the Industrial Revolution when man started widespread use of coal and other fossil fuels. The fact is, about half the world’s electricity comes from coal.
July, 2009 : A NASA satellite study found that Arctic sea ice had thinned dramatically between the winters of 2004 and 2008, with thin seasonal ice replacing thick older ice as the dominant type for the first time on record ( earlier post ).
