The reduction of global methane emissions is critical to keeping global heating within 1.5°C and preventing climate tipping points from irreversibly changing the planet’s climate system. Without mitigation, methane emissions from all three sectors are projected to continue to increase steadily, by up to 150 per cent of 2010 emissions in 2100.
Methane emissions are a threat to global climate and human health. Atmospheric methane concentrations are at their highest ever, having risen by almost 10 per cent in the past 20 years.
COP27 will take place in Sharm-El-Sheikh from the 6th to the 18th of November, a crucial time to put methane at the center of discussions.
This report, produced jointly with Changing Markets and GAIA, provides recommendations for governments on immediate actions that can be taken in national action plans, identifying specific measures and policies to cut methane in the main methane-emitting sectors: energy, agriculture and waste.
The expected expansion of plastic production will emit greenhouse gases (GHG) equivalent to an estimated 56 Gt CO2e between 2015-50, representing 10-13 per cent of the entire remaining carbon budget. Addressing plastic production is therefore a climate priority and the adoption of a new global plastics treaty which promotes a circular economy for plastics and controls plastic production is a key climate strategy.
To stay well below 2°C and limit global warming to 1.5°C, the global community must take decisive action to reduce methane emissions from the energy sector and transition to alternative energy sources.
