Oil and gas exploitation in combination with fracking releases large amounts of methane gases
. Methane (CH4) is a main natural gas component and 25 times more potent in trapping heat in the atmosphere compared to carbon dioxide (CO2). A study
ran by the National Oceanic and Atmospheric Administration (NOAA) monitored gas wells in Weld County, Colorado – one of many fracking regions – and discovered that 4% of the methane produced is leaking into the atmosphere. That amount equals representatively carbon emission of 1-3 million cars. In conclusion, methane leakage from wells is much higher as expected further increasing the environmental impact as initially estimated. This is all happening right now and we should not forget that methane persists for about 12 years
in our atmosphere until removed by natural chemical processes. With regards to the Paris agreement, this represents a very critical period requiring humanity to reach a turning point and keep global average temperature rise below 2°C. Compared to pre-industrial times
, global methane emissions has risen from 722 parts per billion (ppb) to 1800 ppb by 2011.
