which together account for some 45 percent of the globe total carbon dioxide emissions, pledged to make significant efforts in the next 10 to 15 years to limit their CO2 EMISSIONS.

It the first time China has committed publicly to halting the decades-long rise of its CO2 EMISSIONS.

However, due to economic factors and policy shifts, China may be poised to achieve this goal even earlier than promised.

China meanwhile promised that its annual CO2 EMISSIONS which have increased by 257 percent since 1990, would stop rising by 2030 or earlier.

and carbon emissions could level off sometime between 2025 and 2030. But, says Karplus, there is still uncertainty over

#Blame the Weather for Last Year s Rise in U s. Carbon dioxide emissions A colder winter was one of the main reasons carbon dioxide emissions from energy use rose in the United states by 2. 5 percent in 2013

since cement production is responsible for more than 5 percent of all man-made carbon dioxide emissions. The Norcem Brevik cement works tucked into a scenic harbor south of Oslo has used waste heat to drive a process called amine scrubbing that at test scales removed between 30 and 40 percent of the total emissions

Some more far-out ideas for capturing carbon from cement making include using concentrated sunlight to drive the production process (see New Cement-Making Method Could Slash Carbon emissions.

A new device could reduce that waste cutting fuel consumption and carbon emissions by as much as 3 percent and saving companies millions of dollars.

Three percent might not seem like much but for context air travel accounts for 2 percent of worldwide carbon dioxide emissions.

They have acknowledged also the current trend of greenhouse gas emissions is over the threshold the Intergovernmental panel on climate change says will keep global temperature rise below the current 2 degrees Centigrade figure.

In it, they also expressed a strong role for natural gas in reducing carbon emissions. The subject of natural gas raises many eyebrows because although that fuel is currently available and inexpensive,

and more energy-efficient process for removing greenhouse gas from power plant emissions has been developed by a multi-institution team of researchers.

Power generating plants are the single largest source of carbon dioxide (CO2) a greenhouse gas that traps heat

According to the U s. Environmental protection agency coal-and natural gas-fired plants were responsible for one-third of U s. greenhouse gas emissions in 2012.

That's why the agency has proposed rules mandating dramatically reduced carbon emissions at all new fossil fuel-fired power plants.

Capturing the world's carbon emissions is a huge job; we need technology that can be applied to many kinds of carbon dioxide sources with the public's full confidence in the safety and sustainability.

Aines says that the MECS-based approach can also be tailored to industrial processes like steel and cement production significant greenhouse gas sources.
