By focusing on SLCP mitigation, international partnerships, regulatory actions, and technological advancements, Mexico is on a path toward achieving its Black Carbon reduction goals and creating a cleaner and healthier environment for its citizens.

Mexico is working with the CCAC to identify primary emissions sources and create a national SLCP inventory

Mexico has been working closely with the Climate and Clean Air Coalition (CCAC) to address its air pollution crisis. As part of this collaboration, Mexico has participated in the Supporting National Planning for Action on Short-Lived Climate Pollutants (SNAP) initiative. This initiative aims to help countries develop national planning exercises on SLCP mitigation.

To facilitate Mexico's participation in the SNAP initiative, the CCAC supported the creation of institutional capacity within the National Institute of Ecology and Climate Change (INECC). This enabled SLCP mitigation activities to be coordinated across all relevant ministries, agencies, and research institutions in Mexico. An extensive consultative process was then initiated to identify primary emissions sources, data gaps, and information gaps.

Following this consultative process, Mexico, with the support of the CCAC, created a national SLCP inventory. This inventory serves as a comprehensive record of the country's SLCP emissions and provides critical data for developing effective mitigation strategies. The development of the national SLCP inventory was a significant step towards creating targeted and informed policies to reduce SLCP emissions and improve air quality in Mexico.

In addition to creating the national SLCP inventory, Mexico's collaboration with the CCAC has led to the launch of the Special Programme on Climate Change in 2014, with a specific focus on SLCP reductions. Mexico has also been an active partner in global initiatives to reduce emissions, such as the 2013 Global Strategy to Introduce Low Sulfur Fuels and Cleaner Diesel Vehicles, which aims to significantly reduce small particulate and black carbon emissions from vehicles.

Through its partnership with the CCAC and the implementation of various initiatives, Mexico has demonstrated its commitment to addressing air pollution and mitigating the impact of short-lived climate pollutants. The creation of the national SLCP inventory is a crucial tool in this process, enabling the country to identify priority areas for intervention and develop data-driven policies to improve air quality for its citizens.

The government has implemented emissions testing for vehicles, with restrictions on driving for high-polluting vehicles

Mexico has implemented a range of measures to tackle air pollution, with a particular focus on vehicle emissions. Air pollution has been a significant issue in Mexico City for decades, largely due to the city's high altitude, which causes oxygen levels to be 25% lower, and the proliferation of vehicles.

In recognition of this problem, the Mexican government has introduced various policies and regulations to reduce vehicle emissions and improve air quality. One key measure is the implementation of emissions testing for vehicles. The government has set standards for acceptable emissions levels, and vehicles are required to undergo testing to ensure they meet these standards.
