Reducing Short-lived Climate Pollutant Emissions from the Waste Sector through the Climate and Clean Air Coalition

Abt Associates is supporting the U.S. Environmental Protection Agency (EPA) in its role as a lead partner in the Climate and Clean Air Coalition (CCAC) Municipal Solid Waste Initiative. The CCAC is a voluntary partnership uniting governments, intergovernmental and non-governmental organizations, and representatives of civil society and the private sector in the first global effort to address emissions of short-lived climate pollutants (SLCPs), including methane and black carbon.

Through the CCAC’s Municipal Solid Waste Initiative, lead partners such as EPA are working with stakeholders in developing country cities – for example, government officials, sanitation engineers, and private entrepreneurs – to build capacity to improve waste management in ways that help reduce SLCP emissions.

The EPA has partnered with several developing country cities through this initiative, including Accra, Ghana; Addis Ababa, Ethiopia; Amman, Jordan; Coimbatore, India; Dhaka, Bangladesh; Jakarta, Indonesia; Pune, India; and Rio de Janeiro, Brazil.

In each of these cities, Abt Associates assists EPA in:

  • Working with local stakeholders to collect and evaluate data on waste management activities;
  • Analyzing waste management practices and opportunities to mitigate SLCP emissions;
  • Developing city-specific work plans for improving solid waste management and reducing SLCP emissions;
  • Planning and facilitating capacity building trainings and workshops; and
  • Enabling the dissemination of best practices through networking and city exchanges.

Abt also supports EPA in a number of cross-cutting technical, analytical, and outreach activities such as:

  • Evaluating methodologies for quantifying black carbon and methane emissions from the waste sector;
  • Developing a tool for quantifying SLCP emissions from city waste management activities;
  • Designing infographics, fact sheets, posters, and presentations on opportunities and barriers to mitigating SLCP emissions from the municipal solid waste sector; and
  • Facilitating regional and global meetings to enable initiative participants to exchange ideas and lessons learned.

This work is closely related to assistance that Abt is providing to EPA, in support of its role as a lead partner in the Global Methane Initiative.
