Greenhouse Gases

Drive Clean Seattle relies on carbon neutral electricity to power a growing fleet of EVs.

Reduce the amount of food you discard. Turn down the thermostat by three degrees for eight hours a day. Consume less meat.

Honda announces updates to Green Path, its big project to reduce GHG emissions by 50 percent by 2050.

The University of Michigan Transportation Research Institute calculates the average MPG of new cars sold in the US, and finds that June was worse than May.

You try to do a good thing, but someone always has to come around and say there's a down side. In this case, the good thing is AB 32, also known as California's greenhouse gas emission reduction law, and the potential down side is one that could generate a lot of bad publicity.

Among all the various factors playing into the collapse of bee colonies around the world, one of them could be your car. A UK study into how diesel exhaust fumes may affect bees' ability to pollinate flowers found that nitric oxide (NO) and nitrogen oxide (NO2) - NOx gases - change the chemical composition of floral odors, making it harder for them to identify and locate flowers that they're normally attracted to, Damon Lowney

Fuel-efficient cars might be nearly synonymous with Toyota here in the US, but in Mexico, the Japanese automaker is reportedly leading a fight in a dustup over more stringent automobile fuel efficiency regulations. Mexico's government is reportedly trying to make its own mile-per-gallon rules the same as those in the US as part of an effort to reduce greenhouse gas emissions throughout its economy, but Toyota isn't taking too kindly to the proposed legisl

It's got to be difficult to accurately measure and predict the amount of greenhouse gases in the atmosphere, but if tests by the World Meteorological Organization (WMO) are correct, then things are getting worse than people originally thought.

Operating an electric vehicle in China today emits more greenhouse gases than simply driving a gasoline-fueled equivalent, according to emissions expert Juerg Gruetter of Gruetter Consulting. The reason is that, despite the country's push to promote electric vehicles, China's power grid is so overwhelmingly fed by dirty coal that recharging the battery-powered rides will release far more emissions than just putting gasoline in the tanks of the nation's 200-plus million registered vehicles.

Tiny chemical particles emitted by diesel fumes could raise the risk of heart attacks, research has shown. Scientists have found that ultrafine particles produced when diesel burns are harmful to blood vessels and can increase the chances of blood clots forming in arteries, leading to a heart attack or stroke.

The Clean Air Act of 2007 gave the Environmental Protection Agency the right to regulate tailpipe emissions due to their dangers to public health. The law also gave states like California the right to set their own emissions policies; a move that could force automaker

The so called Climate Bill, formally referred to as the American Power Act (read it in PDF), contains a wealth of information that could impact the environment, transportation, offshore drilling, clean coal and so much more. Senators John Kerry (D-MA) and Joseph Lieberman (I-CT) presented the bill yesterday with hopes of passing it by the end of the year. Reuters prepared a rundown of some emissions and transportation-related aspects contained in the bill:

Ever since the idea of carbon capture and sequestration (CCS) was first proposed, everyone from politicians to Big Oil lobbyists have spoken of the technology as already up and running successfully and ready for large scale implementation. Well, a new report in the Journal of Petr

The U.S. media's political lens is focused pretty heavily on the health care debate right now, but that doesn't mean other items of interest aren't happening in Washington, D.C. For example, debate over the EPA's endangerment finding that found that greenhouse gases (GHGs), including those from on-road vehicles, threaten the public health and welfare of the American people is far fro

Last spring, the EPA ruled that it could regulate CO2 and five other greenhouse gases under the Clean Air Act because they are could be harmful to the health of humans. Automakers quickly Sebastian Blanco
