But if they make cuts while the poor go on a carbon-heavy growth binge, the climate will suffer anyway.
He pointed out that carbon emissions are heavy, and finding a place to deposit them will not be easy.
And a new study confirmed suspicions that electric cars that are powered by energy from coal plants have a heavy carbon footprint.
By tuning the laser very precisely to the frequency of one particular sort of bond (such as that with a heavy carbon atom at one end), a molecule containing that bond can be shaken up.
The Anthropocene's equivalent of iridium is nitrogen - although there will be other candidates (such as heavy metals, and carbon isotope ratios characteristic of fossil fuel emissions) for geochemists of the far future to identify as the chemical signature of the new epoch's dawn.
Right now, at our current low levels of carbon dioxide, plants are paying a heavy price in water usage.
WSJ: Harrison H. Schmitt and William Happer: In Defense of Carbon Dioxide
Glass--despite being cheap, easy to produce and easy to recycle--is very heavy and racks up the carbon-emission counts during transportation.
The 787, the first jetliner made from a majority of lightweight carbon fiber composites, eliminates hot, heavy and hard-to-maintain pneumatic systems that power key parts of the jet.
Light ones are more easily deflected than heavy ones, so the two forms of carbon get separated, and when each atom reaches a detector at its expected arrival spot, it can be counted.
By analysing the isotopic composition of hydrocarbon molecules from plant waxes of the period, he found what looks like a spike in the amount of recently non-biological carbon (which has a distinctive ratio of light isotopes to heavy ones), lasting between 10, 000 and 20, 000 years.
ECONOMIST: A geological burp may have led to the dinosaurs�� domination
They are managing to use less energy, but because they are so reliant on coal and because they are in a phase of heavy industry right now - emitting an awful lot of carbon, and that is probably set to continue.
Carbon cap-and-trade system for electric utilities starting in 2013 and for heavy manufacturing starting in 2016.
Using gas cookers, or burning candles, for example, both result in indoor levels of carbon monoxide and particulate matter that are just as high as those to be found outside, amid heavy traffic.
That means ethanol (inefficient because of heavy subsidies and high tariffs on imports of foreign ethanol) or liquefied coal (filthy because of high carbon emissions).
