Everyone in the field of Saturday's Petit Le Mans will be competing in the first Green Challenge, a competition to highlight fuel efficiency and lower emissions.

Brookhaven Lab has issued its 2007 Site Environmental Report. Highlights include significant progress on the environmental cleanup of the site, recognition of pollution prevention initiatives, and reduced environmental effluents and emissions.

An energy and environmental system expert has shown it is possible to reduce carbon dioxide -- the main greenhouse gas that contributes to global warming -- using a relatively simple machine that can capture the trace amount of carbon dioxide present in the air at any place on the planet.

The technology could dramatically reduce emissions from transportation.

Mayor Richard M.

Daley has announced a plan to dramatically slash emissions of heat-trapping gases, part of an effort to fight global warming and become one of the greenest cities in the nation.

The diminutive Zenn is silent and has no emissions, but will small electric cars with limited speed and range catch on?

Could combustion without flames be used to build industrial gas turbines for power generation that are much more efficient than current models and produce almost no polluting emissions?

Researchers in the Middle East now provide a possible answer in the International Journal of the Environment and Pollution.

Using data from an environmental satellite, scientists have for the first time detected regionally elevated atmospheric carbon dioxide -- the most important greenhouse gas that contributes to global warming -- originating from manmade emissions.

A long-term study by the Wildlife Conservation Society, the BioDiversity Research Institute, and other organizations has found and confirmed that environmental mercury -- much of which comes from human-generated emissions -- is impacting both the health and reproductive success of common loons in the Northeast.
