One proposed solution is to extract CO2 out of the air by sequestration: capture and store CO2. But that technology is unproven and even if it worked, would require billions of dollars to build.
It would help a lot if we could, at least, remove the carbon from the natural gas used to heat our homes, cook our meals and heat water. Fifty per cent of Canada’s household energy needs come from natural gas, with electricity at 45 per cent in second place, and heating oil at 4 per cent.
