Climate Program

In order to transform LA County through a regional commitment to environmental sustainability, Metro plans and designs infrastructure and assets with changes to climate and stewardship of natural resources in mind.

Metro's guiding document for the climate program is the Climate Action & Adaptation Plan originally released in 2012. The 2019 CAAP outlines how Metro is both fighting climate change and preparing for a changing climate. Below are some of Metro’s resources in the areas of mitigation, and resiliency:


Mitigation is taking action to reduce activities that contribute to climate change. The most prevalent approach for climate change mitigation is reducing greenhouse gas (GHG) emissions. On behalf of Metro, ECSD inventories GHG emissions resulting from operations and is working to reduce these emissions.

  • GHG Accounting: ECSD calculates annual GHG emissions created by Metro’s operations to target strategies for further reducing emissions.
  • Biomethane Implementation Plan (2013): Metro currently operates the largest alternatively fueled fleet in the nation and is committed to explore ways to go beyond compressed natural gas (CNG) to reduce carbon intensity and GHG emissions.
  • GHG Emissions Cost Effectiveness Study (2010): This study explores the costs and impacts of strategies that could be used to reduce agency emissions.


The ability to provide core functions in the face of threats and recover quickly from major shocks or changing conditions. Metro integrates the concept of resilience throughout the Agency as an organizational priority by anticipating, countering, and managing the eventual (or unavoidable) risks associated with a changing climate.

  • Climate Vulnerability Assessment: This assessment evaluates potential system-wide risks to specific climate stressors including extreme heat, wind, storm surges and wildfires, providing a framework for the agency to assess climate-related impacts to assets across its network.
  • Monetizing Environmental Benefits: To date, Metro has generated about $100M from the sale of carbon credits for reinvestment in sustainable infrastructure.
  • Resiliency Indicator Framework Report (2015): The indicators provide a mechanism to measure and prioritize the actions necessary to ensure that assets and networks are resilient in the face of a changing climate. This report is being updated in 2019.
  • Creating a more resilient workforce: Metro is training employees and the greater community in the principles and concepts of environmental resilience.

Additional Resources

Climate Metrics Report (2013): A joint research project with Occidental College, created the foundation for the Resiliency Indicators Framework . This project furthered Metro thinking about how climate resilience could be monitored and measured.

Climate Change Adaptation Pilot Project (2013): Developed in partnership with the FTA, this report outlines how the Agency has taken the initiative to adapt the transit system to make it more resilient to changing climate conditions, identified Metro’s vulnerable assets and discussed the process for prioritizing improvements to develop a more robust and resilient system.

Building Resilience Los Angeles (2016): A guidebook created in partnership between Metro and BRLA to help owners and operators of buildings integrate resilience into our daily lives.
