The level of deployment of carbon capture, utilisation and storage technologies, for both coal and gas, is another crucial factor for future emissions from those two sectors. The International Energy Agency ( IEA ) has said methane emissions from the oil and gas industries could be halved on average , at no cost to the sector , by switching from oil to gas . The announcement coincided with the release of the Agency 's methane emissions tool , which offers up - to - date estimates of oil and gas emissions in eight industries across five countries . In a separate report , the Agency said policies and practices that supported a switch to gas using existing infrastructure would bring carbon dioxide emissions back to 2013 levels .
