Concerns about methane emissions persist, but notwithstanding that challenge, two greater problems loom: First, shifting significantly away from coal to natural gas doesn't get the planet anywhere close to the carbon - reduction levels scientists say we must reach.

Methane emissions derive mostly from landfills, agriculture (particularly rice farming), livestock, and natural gas and coal extraction, while soot, otherwise called «black carbon», results from the incomplete combustion of fossil fuels and derives primarily from primitive cook stoves used throughout much of the developing world, as well as diesel engines and coal - burning power plants.

So, although methane leakage reduces the short - term emissions benefit of switching from coal to gas — and should be addressed for that reason — it does not limit natural gas's potential as a bridge fuel to a low - carbon future.

Naturally Occurring Methane Capture Carbon Offsets — Methane emissions may occur from land areas where coal or other high concentrations of un-extracted fossil fuels are present underground, resulting in a naturally occurring source of GHG emissions.

The tar sands in Canada are an environmental disaster in other ways, but the incremental emissions of greenhouse gases are small compared to the far greater threat of massive coal expansion in China, or potential fugitive emission of methane from fracking, or massive deforestation in Indonesia and Latin America, or any number of other major sources of greenhouse gases.

Methane recovery - Methane emissions, e.g., from oil or gas wells, coal beds, peat bogs, gas transmission pipelines, landfills, or anaerobic digesters, are captured and used as a fuel or for some other economic purpose (e.g., chemical feedstock).

Using a 20 - year GWP for methane, the 50 % goal would achieve reductions of over 2,300 MTCO2e (the equivalent of India and the EU's combined CO2 emissions from coal combustion in 2012) and the 75 % goal would reduce emissions by around 3,400 MTCO2e (nearly as much as all CO2 emissions from coal combustion from OECD countries in 2012).
