Several researchers have commented on the Intergovernmental Panel on Climate Change (IPCC)’s report, stating that it has “significantly underestimated the technological challenges of reducing CO2 emissions.” Hence, global emission reductions will be tougher to achieve than previously believed.

Carbon dioxide emissions caused by UK consumers increased by almost a fifth between 1992 and 2004, research revealed today.

China has clearly overtaken the United States as the world’s leading emitter of carbon dioxide, the main heat-trapping gas, a new study has found, its emissions increasing 8 percent in 2007. The Chinese increase accounted for two-thirds of the growth in the year’s global greenhouse gas emissions, the study found.

Based on business as usual, the International Energy Agency has predicted that global carbon dioxide emissions will increase 57% by 2030 (from 2005 levels).

Berlin and Paris have agreed to support a European Commission proposed deal to reduce carbon dioxide emissions from new cars. The goal is to limit CO2 emissions from new cars to an average of 120 grams per kilometer from 2012.

Idling wastes about 4 percent of a car’s gasoline, experts say. So eliminating idling would cut a car’s greenhouse gas emissions – carbon dioxide and other byproducts scientists believe cause climate change – by the same amount.

The Guardian

A group of US scientists led by Klaus Lackner, a physicist at Columbia University, says they have created a “breakthrough” device that can capture about a tonne of CO2 a day from the air.

A report by researchers at the Brookings Institution states that city residents in the United States produce less carbon dioxide from energy consumption than their country counterparts.

Coral reefs will be the first global ecosystem to collapse in our lifetimes. The one-two punch of climate change that is warming ocean temperatures and increasing acidification is making the oceans uninhabitable for corals and other marine species, researchers said at a scientific symposium in Spain.

According to the Society of Motor Manufacturers and Traders report in Britain, there has been a 13% reduction in average CO2 emissions from new cars since 1997.
