AI Article Synopsis
- No comprehensive analysis has assessed the potential warming reduction from better solid waste management, particularly in relation to the Paris Agreement's temperature targets and the Global Methane Pledge.
- Improved waste management could help achieve a net-zero warming scenario by 2050, possibly avoiding emissions equivalent to 11 to 27 billion tonnes of CO2 relative to 2020 levels.
- To meet these climate goals, significant changes must be implemented quickly, ideally within the next 9 to 17 years, to effectively reduce methane, CO2, and nitrous oxide emissions and curb rising temperatures.
Article Abstract
No global analysis has considered the warming that could be averted through improved solid waste management and how much that could contribute to meeting the Paris Agreement's 1.5° and 2°C pathway goals or the terms of the Global Methane Pledge. With our estimated global solid waste generation of 2.56 to 3.33 billion tonnes by 2050, implementing abrupt technical and behavioral changes could result in a net-zero warming solid waste system relative to 2020, leading to 11 to 27 billion tonnes of carbon dioxide warming-equivalent emissions under the temperature limits. These changes, however, require accelerated adoption within 9 to 17 years (by 2033 to 2041) to align with the Global Methane Pledge. Rapidly reducing methane, carbon dioxide, and nitrous oxide emissions is necessary to maximize the short-term climate benefits and stop the ongoing temperature rise.
