Greenwashing apparently knows no boundaries, either geographically or by industry. For example, Korean supermarket aisles boast products touting their "well-being" attributes, without explaining how they could possibly make anyone well. The Shanghai Expo touts its green activities, as if all that frenzied construction could somehow be offset or mitigated.

Oil is no longer spewing into the Gulf of Mexico -- at least temporarily -- as BP Plc said it choked off the flow from its undersea well that ruptured in April and caused the worst offshore oil spill in U.S. history.

BP said it stopped the leak on Thursday with the tight-sealing containment cap installed three days earlier atop its blown-out well, and awaited on Friday the results of tests on whether the well remains intact.

Changing sea levels have happened before and will happen again in a dynamic world. Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Boulder. The study, which combined sea surface measurements going back to the 1960s and satellite observations, will threaten inhabitants of some coastal areas and islands.

The increasing costs of energy as a result of green policies could hit the UK's manufacturing sector - just as the country needs industry to help boost the economy, a think-tank warned today.

A report from Civitas said efforts to tackle climate change through cutting greenhouse gas emissions and increasing renewable energy generation would significantly push up energy bills for business.

Most of us know about carbon emissions and understand the idea of our own individual "carbon footprint," but here is a new concept that seems to be catching on: carbon offsetting. Carbon offsetting seems to be an indirect way to "reduce" one's carbon footprint - by paying someone else to support eco-friendly projects. Below is a fantastic article from Sierra Club Green Home that helps explain what carbon offsetting is, the projects it supports and other useful information, such as how to make a smart pick of company if you do want to support carbon-offseting.

A solar-powered plane designed to fly both day and night has succeeded in its first attempt at a 24-hour voyage.Taking off from its base in Switzerland, the Solar Impulse HB-SIA soared into the sky at 6:51 a.m. Wednesday local time (9:51 p.m. Pacific time Tuesday), intent on staying in the air nonstop for 24 hours by flying through the night powered purely by the solar energy captured during the day.
