Federal blueprint outlines goals for cutting transportation greenhouse emissions by 2050
On January 10, 2023, the Departments of Energy, Transportation, Housing and Urban Development, and the Environmental Protection Agency released the U.S. National Blueprint for Transportation Decarbonization. It is a strategy for cutting all transportation sector greenhouse emissions by 2050. The blueprint breaks various goals up into sections before 2030, years 2030 to 2040, and years 2040 to 2050.
The following are some goals set for prior to 2030:
- Deploy 500,000 electric vehicle chargers by 2030 for light-duty vehicles;
- Ensure 100 percent federal light-duty vehicle fleet procurement be zero-emission by 2027;
- Decrease aviation emissions by 20 percent by 2030 when compared to a business-as-usual scenario; and
- Continue to support the Zero-Emission Shipping Mission goals to ensure that 5 percent of the global deep-sea fleet can use zero-emission fuels by 2030, 200 or more of these ships mainly use these fuels across the main deep sea shipping route, and 10 large trade ports covering at least three continents can supply zero-emission fuels by 2030.
The following are some goals set for the years 2030 to 2040:
- Ensure 100 percent federal medium and heavy-duty truck and bus fleet procurement is zero-emission by 2035;
- Have 100 percent of new medium and heavy-duty truck and bus vehicle sales be zero-emission by 2040; and
- By 2036, repair or replace 1,000 miles of high-risk, leak-prone, community-owned legacy gas distribution pipeline infrastructure, and an estimated reduction of 1,000 metric tons of methane emissions.
The following are some goals set for the years 2040 to 2050:
- Have a relationship with countries in the International Maritime Organization to adopt a goal of achieving zero emissions from international shipping by 2050;
- Achieve net-zero GHG emissions from the U.S. aviation sector by 2050; and
- Catalyze the production of at least 35 gallons of Sustainable Aviation Fuels per year by 2050, enough to supply the entire sector.
These are very ambitious goals with multiple of them being a full target of 100 percent. Based on these goals, it seems that federal agencies are targeting the largest shares of current transportation emissions first for completion. For example, light-duty vehicles make up 49 percent of current transportation emissions and those goals are all targeted for completion by 2030. Aviation makes up only 11 percent of current transportation emissions and those goals are mostly set for completion by 2050.
Key to remember: Federal agencies have aggressive goals for cutting greenhouse emission from the transportation sector with light-duty vehicles leading the pack.
