Simultaneously Mitigating Near-Term Climate Change and Improving Human Health and Food Security

The authors identified 14 emission control measures targeting methane and black carbon that could reduce projected global mean warming by approximately 0.5°C by 2050. These measures are estimated to prevent 0.7 to 4.7 million premature deaths annually from outdoor air pollution and increase annual crop yields by 30 to 135 million metric tons from 2030 onwards. The economic benefits of methane reductions (USD 700 to USD 5,000 per metric ton) significantly exceed their marginal abatement costs (under USD 250). Combining these short-term pollutant controls with carbon dioxide reduction measures substantially lowers the risk of exceeding the 2°C warming threshold.

• The authors identified 14 specific measures to control methane and black carbon emissions that could lower projected global mean warming by approximately 0.5°C by the year 2050.
• Reducing tropospheric ozone and black carbon is projected to prevent between 0.7 and 4.7 million premature deaths per year from outdoor air pollution and boost annual crop yields by 30 to 135 million metric tons starting in 2030.
• The economic value of reducing methane emissions, estimated at USD 700 to USD 5,000 per metric ton, is considerably higher than the typical marginal abatement costs, which are less than USD 250.
• Implementing controls for short-term climate pollutants alongside carbon dioxide reduction measures significantly decreases the likelihood of crossing the 2°C warming threshold.
