Client Description:

In September 2014, New York City committed to reducing greenhouse gas (GHG) emissions by 80% from 2005 levels by 2050 (80 x 50), with an interim goal of a 40% reduction in greenhouse gases by 2030 (40 x 30). In late 2015, the Mayor’s Office of Sustainability (MOS) brought together a team of experts to develop the 80 x 50 pathway. GNA worked with MOS, the NYC Department of Transportation (DOT) and other City agencies, BuroHappold, and Sam Schwartz Engineering to develop the transportation components of the 80 x 50 plan.

Client Goals:

  • Create an integrated plan to achieve the 80 x 50 goal that combines strategies and actions from the energy, buildings, transportation, and waste sectors.
  • Ensure greenhouse gas reduction strategies also improve air quality and achieve critical policy objectives.

GNA Strategy:

  • GNA worked with MOS, other City agencies, and the other members of the project team to develop the transportation components of the City’s 80 x 50 plan.
  • GNA conducted a global survey of best practices in transportation policies and projects, focused on zero-emission and alternative fuel vehicles, low-carbon and renewable fuels and sustainable freight practices.
  • GNA produced the “Business-As-Usual” forecast of future transportation emissions for 2030 and 2050, which was then integrated into the City’s integrated modeling forecasts.
  • GNA generated a series of strategies and actions related to zero-emission vehicles and other alternative fuel vehicles, low-carbon and renewable fuels, and sustainable freight for consideration by MOS and the project team.
  • GNA created an emissions model that helped the City identify the transportation strategies and actions that would be necessary to meet the 40 x 30 and 80 x 50 goals.

Project Results:

  • The City of New York released its plan to meet the 80 x 50 goal in September 2016: The transportation component of the City’s 80 x 50 plan focuses on reducing the number of miles driven in New York City, while transitioning the remaining vehicle trips to zero-emission vehicles as much as possible.
    • As part of this commitment, the City has launched the NYC Clean Fleet initiative, which aims to create the largest zero-emission vehicle fleet of any U.S. city.
    • Where switching to zero-emission vehicles is not feasible, the City’s plan includes the increased use of low-carbon and renewable fuels.
    • The plan also commits the City to a more sustainable freight strategy through the implementation of the NYC Department of Transportation’s Strategic Plan 2016: Safe-Green-Smart-Equitable.
