Methane matters - A roadmap for the waste sector


CCAC and CCAC Waste Hub member GAIA invite you to join this webinar to learn about the roadmap to reduce methane emissions in the solid waste sector and share experiences of what cities are doing around the world.

As the climate emergency accelerates, efforts to avoid exceeding the 1.5C temperature goal must be reinforced urgently. Methane is a very potent but short-lived gas, responsible for about half of the warming we experience today, and tackling it represents a low-hanging fruit for reducing climate change emissions in the near term.

The new report, Methane Matters: A comprehensive approach to methane mitigation by GAIA, Changing Markets Foundation and Environmental Investigation Agency outlined that methane emissions in the solid waste sector can be cut by as much as 95% by 2030 through low cost, scalable and easy to implement measures focused on waste prevention and the separation and treatment of organic waste.

These measures are already well advanced in many cities with very diverse contexts. The webinar will share a glimpse of different models and policies being implemented by cities in the Global North and Global South.
