Short-lived climate pollutants, such as methane, black carbon and hydrofluorocarbons are up to thousands of times more potent than carbon dioxide. 

The member countries of the Summit of North America agreed joint actions to reduce these pollutants, which will bring entail significant benefits for climate and health in the short term and in the future, and support the goal of limiting global warming in this century.

"Today, Mexico joins Canada and the United States in committing to reduce its methane emissions in the oil and gas sector, the world’s largest methane source, by 40-45 per cent by 2025, to achieve the goals of reducing greenhouse gases covered by our national defined contribution (NDC)”: EPN

To achieve this goal, the three countries commit to develop and implement federal regulations to reduce emissions from new and existing sources in the oil and gas sector, as soon as possible.

They commit to develop and implement national strategies for methane reduction in key sectors such as oil and gas, agriculture and waste management, including food waste.
 
The countries in the region commit to continue to work internally and with international partners with major national actions to reduce black carbon emissions in North America.
