New technology to capture gas from coalfields has recently boosted supplies, which could help keep prices down.
The rules, stronger than earlier proposals, are aimed at reducing methane emissions from the US by 40%to45%5% over 2012 levels by 2025 by requiring companies to capture gas from oil wells, and find and plug pipeline leaks.
Luckily it's easier to capture gas from landfills than from cows.
Alternative energy usage (wind, solar, hydro) must come into play alongside improved environmental-sound use of hydrocarbons (i.e. advance efforts to capture gas from flaring so it can be used as an additional energy resource).
Projects for a technology called carbon capture and sequestration — which are ineligible for Mr. Branson's prize because they aim to capture gases from gas and coal power plants before they are released into the atmosphere — have also fallen behind schedule.
The AI Group also notes that the "safeguards mechanism" – which is supposed to ensure that industrial emissions do not rise and cancel out any reductions bought primarily from avoiding tree-clearing and capturing gases from landfill – would need "substantial amendment" if it was to help reduce greenhouse emissions.

Space-bound printers will also eventually need to capture gasses emitted from the extruded plastics, be able to print their own parts for self-repairs and have some abilities to recycle printed products into new ones.
But capturing the gas from coal plant smokestacks or switching to fuels that produce less of it when burned goes only so far.
We estimated the total potential reductions in emissions from capturing methane gas from anaerobic digestion of dairy, swine and poultry manure and substituting methane for liquefied petroleum gas (LPG) at 308 GgCO2Eq.
