Black carbon, which absorbs heat from the sun, also accounts for anywhere from 10% to more than 45% of the contribution to global warming, and is also linked to accelerated losses of glaciers in Asia, because the soot deposits darken, ice making it more vulnerable to melting.
One study estimates that 26% of black
carbon
emissions are from stoves for heating and cooking, with more than 40% of this amount from wood burning, roughly 20% from coal, 19% from crop residues, and 10% from dung.
Some companies have developed stoves that use passive air flows, better insulation, and 60% less wood to reduce black
carbon
emissions by around 70%.Mass introduction of such stoves could deliver multiple green-economy benefits.
While CO2 can remain in the atmosphere for centuries, other pollutants, including black
carbon
and ozone, remain for relatively periods – days, weeks, months, or years – so that reducing or ending emissions promises almost immediate climate benefits.
This technology is now making its way around the globe, allowing other societies to increase their energy production and decrease both their reliance on costly imports and their
carbon
emissions.
The Kyoto Protocol created a mechanism for trading
carbon
dioxide emissions, which promises to manage the risks of an even bigger potential disaster: global warming.
The costs of a hypothetical project – including construction, resettlement of people living in the dam’s way, and
carbon
emissions – would come to about $3.1 billion.
Benefits from power generation, downstream irrigation,
carbon
offsets, and reduced floods would be worth roughly twice as much.
The state’s extensive environmental and energy regulation, including micromanaging
carbon
emissions, in combination with globalization, has driven away much of California’s manufacturing and many of its middle-class jobs.
The US also is set to become energy independent, owing to the rise of shale oil and gas, with diminishing reliance on coal already bringing down per capita
carbon
emissions.
Notably, the business sector is asked to take a more active role to reduce its
carbon
footprint, commit to 100% renewable energy and zero emissions, shift investments into renewable energy, adopt more sustainable business models, and assist in the divestment from fossil fuels.
Indeed, it is important to remember that the earth’s surface is primarily ocean, which plays a critical role as both a
carbon
sink and a regulator of the climate.
The
carbon
dissolved in the ocean has altered its chemistry, driving up acidity by 30% since the beginning of the Industrial Revolution.
It is flawed economically, because
carbon
taxes will cost a fortune and do little, and it is flawed politically, because negotiations to reduce CO2 emissions will become ever more fraught and divisive.
In Copenhagen this December, the focus will be on how much
carbon
to cut, rather than on how to do so.
Green and Galiana examine the state of non-carbon-based energy today – nuclear, wind, solar, geothermal, etc. – and find that, taken together, alternative energy sources would get us less than halfway toward a path of stable
carbon
emissions by 2050, and only a tiny fraction of the way toward stabilization by 2100.
Today’s politicians focus narrowly on how high a
carbon
tax should be to stop people from using fossil fuels.
The market alone is an ineffective way to stimulate research and development into uncertain technology, and a high
carbon
tax will simply hurt growth if alternatives are not ready.
Green and Galiana propose limiting
carbon
pricing initially to a low tax (say, $5.00 a ton) to finance energy research and development.
Compare this to other analyses showing that strong and immediate
carbon
cuts would be expensive, yet achieve as little as $0.02 of avoided climate damage.
Another idea is to try to raise more revenue from
carbon
permits or taxes.
That means a decisive shift from carbon-emitting energy sources like coal, oil, and gas, toward wind, solar, nuclear, and hydroelectric power, as well as the adoption of
carbon
capture and storage technologies when fossil fuels continue to be used.
Per capita
carbon
emissions in US coal states tend to be much higher than the national average.
But energy-intensive industries usually benefit from exemptions on
carbon
charges.
In the European Union,
carbon
prices have been low for several years, and for now market participants seem to be following the herd in believing that they will remain so.
At the least, companies should earn
carbon
credits for the CO2 they capture and store.

dioxide into the atmosphere, since peaking in 2007, have fallen by 12% as of 2012, back to 1995 levels.
A Healthy, Climate-Friendly DietBERLIN – This December, world leaders will meet in Paris for the United Nations Climate Change Conference, where they will hammer out a comprehensive agreement to reduce
carbon
emissions and stem global warming.
Taken together, schooling and family planning could translate into a 120-gigaton reduction in
carbon
dioxide emissions over the next three decades, as fewer people consumed fewer resources.
First, G20 countries must acknowledge that energy, climate, and development are closely interrelated and stop subsidizing
carbon
emissions.
