America is the biggest source of CO2 in the world.
The technique developed by Liquid Light needs a relatively pure source of CO2.
Despite recent pronouncements on Heathrow and Stansted, aviation remains the fastest growing source of CO2 emissions in the UK.
But what of the rest?The fastest growing source of CO2 emissions is traffic.
And that's not all: although fossil fuel combustion is the main source of CO2, we also release the same gas by clearing forests and producing cement.
The key source of CO2 is the burning of fossil fuels such as coal, oil and gas, though deforestation is also a very significant contributor.
Even so, current plans for energy saving will not meet the 20% target on their own.That leaves reducing emissions from power generation, currently the biggest source of CO2.
The US Environmental Protection Agency states that, while fossil fuel use is the primary source of CO2: "The way in which people use land is also an important source, especially when it involves deforestation".
I'm sure that it would still be the largest point source of CO2, but since CO2 emissions have grown faster than projected in 1989, it would probably account for a smaller fraction of global CO2 emissions," Bernstein wrote.
The 1,000 fossil fuel-fired power plants in US are by far the largest source of CO2 emissions in the country, making up 32% of total greenhouse gas emissions.
Coal utilization is the main source of CO2 emission.
