18 states sue EPA over greenhouse gas pollution
April 3, 2008 08:41 AM - Reuters

WASHINGTON (Reuters) - Eighteen states sued the Environmental Protection Agency on Wednesday for failing to limit greenhouse gas emissions from new cars and trucks, one year after the Supreme Court ruled that the agency had the power to do so. The suit seeks EPA's response to the high court's April 2, 2007, ruling, a landmark decision seen as a sharp defeat for the Bush administration's policy on climate change.

Beijing pollution risky for endurance athletes
April 2, 2008 06:41 AM - Reuters

BEIJING (Reuters) - Endurance events at the Beijing Olympics could pose a health risk if they are staged on heavily polluted days, the International Olympic Committee said on Wednesday, although it was prepared to reschedule such events. Hein Verbruggen, chairman of the IOC coordination commission, said there was a small chance of athletes suffering some damage to their health if they took part in events lasting longer than an hour, such as the marathon and cycling road races.

Australia trials underground carbon storage
April 2, 2008 12:53 AM - Reuters

CANBERRA (Reuters) - Australia on Wednesday began pumping 100,000 tons of carbon dioxide underground in a test of carbon storage that environmentalists said would do little to tackle climate change. The CO2 is stripped from a natural gas well but the idea is to see if the scheme can be expanded to capture CO2 from coal-fired power stations, whose emissions are blamed in part for global warming.

GreenDisk: a viable e-waste solution?
April 1, 2008 09:11 AM - , Triple Pundit

Computers are becoming cheaper and easier to manufacture by the minute. Intel's new Atom processor is bound to create a whole new set of net-enabled devices at extremely low cost. While the processor is not out yet and prices are not set in stone, rumors price new "net-top" computers below $200. Cheaper computers make electronic recycling all the more relevant. Computers and gadgets are being replaced more frequently as electronics become obsolete in a matter of months.

EPA criticized over new lead paint rule
April 1, 2008 12:20 AM - Reuters

WASHINGTON (Reuters) - The U.S. Environmental Protection Agency offered a new rule on Monday aimed at shielding children from the risks of lead-based paint, but a watchdog group said the rule needs to be tougher. The rule affects professional contractors who renovate or repair homes, schools or child-care centers built before 1978, when lead-based paint was banned for residential use. Ordered by Congress in 1992, the rule takes effect in April 2010.

Invention: Diamond-cooled nuclear reactor
March 31, 2008 09:37 AM - New Scientist

Nuclear plants can fail when the heat from the reactor is not removed quickly enough from the core. This can happen in pressurised water nuclear reactors if the water in the cooling system boils, because steam is a much poorer conductor of heat than liquid water. These reactors have a primary water cooling system that directly takes heat away from the reactor. It is sealed under huge pressure to prevent it boiling and conducts heat to a secondary water cooling system that is not sealed.

65 Million Square Feet of Solar Rooftops: Powering 162,000 Homes

In an ambitious move, a Californian utility plans to create a massive, distributed “powerplant” by installing a total of 2 square miles of solar cells on the roofs of businesses. Southern California Edison plans to install 250 megawatts’ worth of solar power, generating enough electricity to power 162,000 homes.

Beijing aims to cut down smoking for Olympics
March 31, 2008 01:33 AM - Reuters

BEIJING (Reuters) - Beijing will ban or restrict smoking in most public venues in May as part of its pledge to hold a smoke-free Olympics, local media reported on Monday, citing the city's legal office. New legislation to take effect on May 1 will forbid smoking at government offices and on public transport, the Beijing Morning Post said, but falls short of setting outright bans at restaurants, bars and clubs.

A Close Look at the Current State of Mattress Recycling
March 28, 2008 11:39 PM - , Green Lodging News

Usually when people think of recycling, they think of smiling trash cans eagerly welcoming happy bottles and cans. However, most people don’t really think about mattresses. With a number of major landfills starting to run out of space, discarded mattresses have been a thorn in the side of landfill operators. How big of a thorn? A single mattress can take up to 23 cubic feet of space. Over the past few years, the concept of mattress recycling has begun to gain traction. There have been a number of drivers towards mattress recycling, including legislation and the increasing burden that mattresses cause landfill operators.

Someday soon, probably sooner than we think, we’ll have to get serious about removing carbon dioxide from coal-fired power plant exhaust, perhaps even extracting it from the atmosphere as well. The Arctic ice cap is shrinking in area and thickness. Another state-sized ice shelf is breaking away from Antarctica as this story is being written. Global warming is blamed for the dramatic changes going on at the extremes of the planet — our home.
