The need for urgent action has been emerging as a primary theme of the Copenhagen Climate Congress this week—including urgent action on mitigation strategies that complement aggressive cuts in CO2 emissions. “Everyone must understand the urgency of this matter and the potential costs,” Danish Minister of Climate and Energy Connie Hedegaard said in her opening remarks.

With reducing carbon emissions on the national agenda, a group of expert panelists will discuss methods, markets, testing and policy issues on how carbon sinks or carbon sequestration may be used to reduce atmospheric CO2.

Nissan Motor Co., Ltd. will apply a series of breakthrough technologies in its manufacturing paintshops worldwide. This will translate to a lower impact on the environment through reduced energy consumption, CO2 emission and waste-solvents (VOC) compared to existing methods.

Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today.

The Government of Portugal and the Renault Nissan Alliance today announced a partnership to promote zero-emission mobility across that country. The partnership was launched today in Lisbon, in the presence of Mr. José Sócrates, the Prime Minister of Portugal, and Mr. Carlos Ghosn, President and CEO of Renault and President and CEO of Nissan.

In future, climate change will bring an increase in salty surfaces on the Earth and in the concentration of CO2 in the atmosphere. However, this higher CO2 has some positive effects on the physiology of barley plants and increases its tolerance to salinity.

For the past three years, the European Union has been operating the world's largest emissions trading system and the first system to limit and to trade carbon dioxide emissions.

Dell today announced aggressive plans to further reduce the energy consumption of its products, avoid millions of tons of CO2 emissions worldwide and drive unprecedented customer value.

Around 400 Denver residents, including the city's mayor, are part of an experiment called "Driving Change." The program has been running since mid-March, and on Monday participants were able to check their "scores" online for the first time.

Add university research to the long list of human activities contributing to global warming.

The potential of no-tillage (NT) soils for increasing the soil organic carbon (SOC) pool must be critically and objectively assessed. Most of the previous studies about SOC accrual in NT soils have primarily focused on the surface layer (<20-cm soil depth), and not for the whole soil profile. The lack of adequate data on the SOC profile is a hindrance to conclusively ascertain the effects of NT farming on SOC sequestration and off-setting CO2 emissions.

Levying a price on carbon dioxide released by electric generators could considerably reduce greenhouse gas emissions — even before the deployment of any environmentally friendly technology — according to scientists in Pennsylvania. Their report is scheduled for the May 1 issue of ACS’ Environmental Science & Technology, a semi-monthly journal.
