Projected number of heat emergency days. Baseline: 29 days. 2020: 50 days, 2050: 70 to 80 days, 2080: 75 to 105 days. 75% of the District's GHG emissions come from buildings. 1 metric ton of GHG emissions is equivalent of 2.451 miles driven by an average car. The District's GHG emissions are down 29% from the 2006 baseline. The District is already experiencing the impacts of human-made climate change. Climate change refers to long-term changes in global temperature, precipitation, wind patterns, and other aspects of climate. These global changes have serious consequences at the District level. In the past few years, the District has seen record-breaking extreme weather (like heat waves and snowstorms), higher tides caused by rising sea level, heavy rains and flooding, and warmer average temperatures and two to three times as many dangerously hot days.

The District Government is approaching climate change from two sides: mitigation and adaptation. Mitigation refers to reducing the following greenhouse gas emissions (GHGs)—carbon dioxide, methane, and nitrous oxide. The District’s Clean Energy DC plan is the roadmap to achieve the Sustainable DC goal of reducing GHGs by 50% by 2032. The District is also committed to becoming carbon neutral by 2050. Progress toward this goal is measured by an annual inventory of the city’s GHGs. Since the District began tracking GHGs in 2006, emissions have fallen by approximately 29 percent. This is progress, but there is much more work to do. Adaptation means being prepared for the impacts of climate change. The District Government has outlined how the city will adapt in the Climate Ready DC plan.

Sustainable DC 2.0’s actions on climate have real-world benefits for the District at all levels:

  • Individual: Climate change will impact all residents, but the impacts for some may be more serious, based on a number of factors: age, income level, geographic location, and other characteristics. The actions in Sustainable DC 2.0 focus on helping all residents adapt to climate change, especially those most at-risk economically and physically, and shows that mitigation efforts shouldn’t unfairly burden people with low incomes.
  • Neighborhood: Climate change may impact parts of the District differently. Low-lying neighborhoods near the Potomac and Anacostia Rivers are more likely to be impacted by sea level rise and coastal flooding, while neighborhoods without green vegetation are more likely to be impacted by heat waves. Sustainable DC 2.0 focuses on improving the adaptive capacity of neighborhood building blocks—transit, energy, water, and telecommunications—so communities can bounce back quickly after extreme weather events.
  • District: Sustainable DC 2.0 helps set climate adaptation and mitigation priorities for the entire city. These requirements include specific policies tailored toward the District Government and stakeholders, such as real estate developers, whose work impacts many people.

Sustainable DC Climate Goals:

The Sustainable DC 2.0 goals are to:

  • Reduce greenhouse gas emissions from all local sources to put us on track to eliminate emissions by 2050.
  • Advance physical adaptation and human preparedness to increase the District’s resilience to climate change.

Where We Are

The District has appointed a Chief Resilience Officer to help coordinate resiliency efforts, including climate, and developed the Resilient DC plan. In 2020, the Chief Resilience Officer also took on the role of Chief of Resilience and Emergency Preparedness. The District has also developed a detailed climate mitigation plan (Clean Energy DC) and a climate adaptation plan (Climate Ready DC). DC participates in several international and national programs helping combat climate change, most notably 100 Resilient Cities, the American Cities Climate Challenge, and C40. However, District Government is focusing much of its attention at the hyper-local level with community advisory groups working on resiliency hubs in Far Northeast Ward 7 and hosting ongoing community discussions on renewable energy and equity in Ward 8. While the District Government puts out a GHG inventory each year, we are looking out even further to determine how we will reach Mayor Bowser’s commitment to becoming carbon-free by 2050.
