Pollution

Garbage is dirty, but is it a clean fuel?
May 21, 2008 08:18 AM - Reuters

About 45 minutes north of downtown Los Angeles, a machine the size of a small truck flattens tons of food scraps, paper towels and other household trash into the side of a growing 300-foot pile. To Waste Management, which operates the landfill, this is more than just a mountain of garbage. Pipes tunneled deep into the mound extract gas from the rotting waste and send it to a plant that turns it into electricity.

Honda to roll out cheap new hybrid model in early '09
May 21, 2008 03:53 AM - Reuters

TOKYO (Reuters) - Honda Motor Co <7267.T> said on Wednesday it would launch a new, low-cost hybrid car in Japan, North America and Europe in early 2009 as it seeks to cut the lead of Toyota Motor Corp <7203.T> in the green car race. Despite the pressure of record-high oil prices and concerns over climate change, fuel-efficient and low-emission hybrids still occupy a small niche in the global car market, partly due to their higher costs for both consumers and automakers.

30 Agrochemical Products Banned in Nigeria After Deaths
May 20, 2008 08:27 AM - , Organic Consumers Association

The National Agency for Food and Drug Administration and Control (NAFDAC) has banned the sale and supply of 30 different agrochemical products in the country. NAFDAC Director-General, Professor Dora Akunyili, explained in Abuja that the ban became necessary when it was discovered that the pesticides were causing food poisoning that had resulted in the death of many after they consumed food crops preserved with the chemicals.

Population and Climate Change: Can We Talk?
May 20, 2008 08:23 AM - Robert Engelman, Worldwatch Institute

ISTANBUL-The workshop I've been attending in this ancient city drew 31 people-ranging from a member of the British parliament to a Dutch women's rights advocate to a Hungarian environmentalist-to talk about whether it makes sense to bring population into the global debate on climate change.

Brazilian Companies Announce Global Warming Game Plan

The Brazil Greenhouse Gas Protocol Program was launched today and its 12 founding corporate members have voluntarily agreed to report their global-warming emissions. “The program provides options for sound measurement and allows members to take action to reduce their GHG emissions,” said Thelma Krug, secretary of climate change, Brazil Environment Ministry, at the launch event here in the IBAMA Auditorium.

China quake may cut carbon offset supply
May 15, 2008 09:29 AM - Reuters

China's deadliest earthquake in decades could cut by up to 5 percent the country's supply of carbon offsets under the Kyoto Protocol over the next 12 months, a market China dominates, Lehman analysts estimated on Thursday. Rich countries can meet Kyoto greenhouse gas limits by investing in emissions cuts in developing countries, earning carbon offsets in return.

Greenhouse gases highest for 800,000 years
May 15, 2008 08:15 AM - Reuters

Greenhouse gases are at higher levels in the atmosphere than at any time in at least 800,000 years, according to a study of Antarctic ice on Wednesday that extends evidence that mankind is disrupting the climate. Carbon dioxide and methane trapped in tiny bubbles of air in ancient ice down to 3,200 meters (10,500 ft) below the surface of Antarctica add 150,000 years of data to climate records stretching back 650,000 years from shallower ice drilling.

IdleAire: Reducing Trucker's Environmental Impact
May 14, 2008 09:07 AM - , Triple Pundit

If you've ever been on a road trip, you've probably seen this sight at a rest stop: one, or many big rig trucks, just...idling. Not going anywhere. What is this, like a computer on "sleep," ready to go? No. The answer may surprise you. At least in the US, truck drivers are required to rest 10 hours for every 11 driven. A reasonable thing, but this often necessitates them sleeping in their cabins. And that requires power for the heating or cooling, and other comforts of "home" on the road. Power that comes from a running truck.

Study sees threat from big-particle pollutants
May 14, 2008 08:15 AM - Reuters

On days when there is a lot of dust and other large-particle pollutants in the air, slightly more elderly people go to hospital emergency rooms with heart problems, U.S. researchers said on Tuesday. There was also an increase in hospital visits by elderly patients complaining of respiratory illnesses when "coarse," or large, particle pollution was plentiful, although the rise was not significant, the researchers said.

Carbon monoxide aids shift from active infection to a drug-resistant dormant TB infection
May 13, 2008 09:04 AM - University of Alabama at Birmingham

A toxic gas present in air pollution and tobacco smoke plays a significant role in triggering tuberculosis infection, according to a new study from researchers at the University of Alabama at Birmingham (UAB). The UAB study focused on carbon monoxide (CO), a colorless, odorless gas present in tobacco smoke, and vehicle and manufacturing plant emissions. Also, CO is produced naturally in brushfires and volcanic gas.
