The reporting of greenhouse gas emissions by major sources of these pollutants is gaining momentum.

The U.S. Environmental Protection Agency (EPA) is finalizing requirements under its national mandatory greenhouse gas (GHG) reporting program for underground coal mines, industrial wastewater treatment systems, industrial waste landfills and magnesium (more…)

As good stewards of the planet we live on, it is often a good idea to measure our impact on the Earth and adjust accordingly. One of the best ways to do this is to calculate our carbon footprint. A carbon footprint is a rough measurement of greenhouse gases (GHG) that an individual, organization, event, or product produces. In this case we are looking at an individual assessment of GHG.

Luckily there are many online tools that will calculate your carbon footprint for free. (more…)

Growing algae for biofuels is an energy-intensive process that can generate more greenhouse gases than the process sequesters, according to a new study.

Examining the life cycle of algal biofuels, researchers from the University of Virginia found that the process emits high levels of greenhouse gases because algal production requires using large amounts of fertilizer.

Global emissions of carbon dioxide will drop 3 percent in 2009, including a 5.9 percent decrease in the United States, as a result of the economic recession, according to energy forecasts.

A decrease in industrial activity accounts for three-quarters of the global emissions decline, the International Energy Agency reported at United Nations climate talks in Bangkok. The rest of the decline is the result of nations switching to renewable energy sources and nuclear power.

In the U.S., coal demand will likely drop 9 percent this year as electricity demand slips and more states switch to natural gas in the face of stiffer government oversight of greenhouse gas emissions, according to the U.S. Energy Information Administration. Economic recovery would likely reverse the trend, and the agency predicts a 1.1 percent increase in CO2 emissions in 2010.

The Obama administration has announced it will use its regulatory powers to limit CO2 emissions from 14,000 major sources, a move that puts pressure on Congress to pass a climate bill and signals to other nations the U.S.’s willingness to slow global warming.

Lisa Jackson, administrator of the Environmental Protection Agency (at left), said her agency would begin regulating CO2 as a pollutant at coal-burning power plants, refineries, and big industrial complexes, which account for 70 percent of U.S. greenhouse gas emissions.

The EPA will initially use its authority to force these emitters to employ “best available technology” to implement energy-efficiency measures and reduce emissions, but eventually the agency could place emissions caps on these facilities.

“We are not going to continue with business as usual,” Jackson said. “We have the tools and the technology to move forward today, and we are using them.”

Rapid population growth in the developing world does not significantly contribute to rising greenhouse gas emissions and focusing on the population explosion in poor countries diverts attention from the far more serious issue of over-consumption in rich countries, according to a new study.

The study, conducted by the International Institute for Environment and Development, analyzed population growth and CO2 emissions from 1980 to 2005 and concluded that rising populations in sub-Saharan Africa and other poor regions have had a negligible impact on global warming.
