Yeast is then added, converting sugar into alcohol and carbon dioxide gas.
Nematodes and bacteria capture and store carbon that otherwise contributes to global warming when allowed to overload the atmosphere in the form of carbon dioxide gas.
It was finally concluded that the lake's lower levels had become saturated by carbon dioxide gas (CO2) due to gaseous springs which bubbled up from the extinct volcano beneath.
In fact, the revenues raised by a carbon or gas tax could be used to fund the public-private partnerships that have so successfully spurred private sector innovation in the past.
FORBES: Raising Gas Taxes Wouldn't Cut Consumption, But It Still Makes Sense
They show that warming spells very like that of the past 100 years occurred repeatedly, long before the large-scale use of fossil fuels and the associated emissions of carbon dioxide gas were a possible factor.
It is thought that recent high rainfall had displaced the CO2-rich water at the bottom, releasing a massive bubble of carbon dioxide gas from the lake in a natural phenomenon now referred to as "lake overturn".
The scrubbed alkaline clay would then be combined with treated flue gas, which is a carbon-rich gas that is normally released into the atmosphere during the manufacturing process.
The company said all the vehicles would meet European emissions standards, while some would be low carbon hybrid or gas versions.
Which of the following countries had higher emissions of the greenhouse gas carbon dioxide, per capita, in 2008 than the other two?
Understanding the changes caused by the volcanic eruption will help researchers predict how the oceans will respond to certain levels of the greenhouse gas carbon dioxide, Fraile-Nuez said.

Clearing land to plant food for biofuel releases the greenhouse gas carbon dioxide (CO2) through ploughing and can involve deforestation, which reduces the "carbon sinks" - the trees that absorb CO2.
Government scientists said Tuesday that 2012 was among the top ten warmest on record globally and continues a trend of rising temperatures due to increasing emissions of the greenhouse gas carbon dioxide.
Another consideration is that while Noah is correct that carbon taxes and gas taxes are unpopular, so are the taxes that would be needed to raise the money for the research he wants.
"At this field site, we are very lucky to have two key bioenergy crops growing side-by-side, which is allowing us to make a comparison of their effects on soil carbon and greenhouse gas emissions from the soil, " he told BBC News.
BBC: Measuring bioenergy crops' carbon footprint credentials
Sir David King, Tony Blair's chief scientist, recently argued that one further generation of nuclear power stations is needed (in Britain at least) to buy time, in order to keep down emissions of carbon dioxide, the chief greenhouse gas, while new carbon-free non-nuclear technologies are developed.
Scientists presume that carbon sinks can slow the effects of global warming by trapping the main greenhouse gas, carbon dioxide.
The U.S. Energy Information Administration says increased use of natural gas has come at the expense of coal, which tends to emit significantly more carbon dioxide than natural gas.
The carbon combines with the hydrogen in water to make carbon monoxide and hydrogen gas--the old "town gas"--but then the catalyst prompts a rejiggering of the atoms into methane (one carbon atom attached to four hydrogen atoms).
When anticipated supply is sufficiently high, gas undercuts coal as the fuel of choice for electrical generation, which results in reduced carbon dioxide emissions, as natural gas produces only about 50% to 70% of the carbon dioxide per unit output (depending upon your metric) that coal does.
He added that there was a need to for "carbon capture in storage for gas-fired power stations" to ensure that the carbon is not released into the atmosphere.
The un-burned, leaked gas is 72 times more potent than carbon dioxide -- a greenhouse gas -- making it more damaging to the environment, Krupp said.
While natural gas is a fossil fuel that emits carbon dioxide, tapping into the gas hydrates assessed in the study is not expected to affect global warming, said Brenda Pierce, coordinator for the USGS Energy Resources Program.
Most studies to date suggest that shale-gas wells may lead to slightly higher carbon-dioxide emissions than conventional-gas ones because more wells are needed and fracking requires lots of power from diesel motors.
ECONOMIST: Shale gas��s poor image in Europe is largely unjustified
Gas is a hydrocarbon, albeit the cleanest, so burning gas releases carbon dioxide into the atmosphere.
Carbon emissions from natural gas are lower than alternative fuels and it is widely considered the fuel for the next generation.
As environmentalist Bjorn Lomborg notes, manufacturing and charging electric cars over their life cycle can produce more carbon than small, gas-powered vehicles.
Shell's gasification technique consists of partially combusting pulverized coal to yield carbon monoxide and hydrogen gas, which combine to form synthetic natural gas.
On top of that, a lot of methane (a far more potent greenhouse gas than carbon dioxide) emerges when all this food rots.
Carbon monoxide is a gas which is odorless tasteless and colorless.
Greenhouse gas (carbon) emission for these vehicles also must fall by 34 percent from the 2016 levels by 2025, according to the California Air Resources Board.
