Generally overshadowed by discussions on the essential reduction of carbon dioxide (CO2), methane (CH4), another powerful greenhouse gas, is at the heart of a World Forum being held in Geneva this week.
The objective: to
“
promote reproducible successes
”
in reducing emissions linked to human activity and
“
mobilize action
”
to accelerate their decline.
The main component of natural gas, methane has a warming power 28 times greater than CO2 over 100 years.
Satellites allow us to know more about its origins: if 40% of it comes from natural sources such as wetlands such as peat bogs, the majority of emissions are linked to human activity.
Agriculture, with bovine digestive fermentation or rice cultivation, constitutes the first anthropogenic source of emissions, followed closely by energy, particularly due to leaks from fuel extraction, storage and transport infrastructures, etc.
