New York

The urban mobility emissions trajectory is moving in the right direction, but more efforts are needed for the city to achieve the 1.5°C target by 2030.

Introduction

New York has a well-balanced mobility network that offers a variety of options

New York offers a great mix of mobility services, with a balanced modal share between cars (28%), public transit (41%), walking (28%), and other modes. Mobility demand in New York accounted for 60 billion kilometers (37 billion miles) traveled in 2022, generating 3.7 MtCO2e.

More than a quarter of distance traveled was by car, contributing to 68% of city mobility emissions in 2022. And while reducing car emissions is a key lever to reaching the Paris Agreement target, New York is already less car reliant than many other cities due to its balanced mix of mobility services.

New York City pledged in 2023 to improve infrastructure that can help boost active mobility modes like cycling and walking. The NYC Department of Transportation is expanding bike lane infrastructure and e-bike accessibility as ridership reaches record levels, as well as “super sidewalk” re-designs of major pedestrian spaces.

Current situation

New York is on the right path to reaching the Paris Agreement goals, but more sustainable action is needed

Based on city plans, mobility demand is expected to grow by 9% by 2030 while CO2 emissions are forecasted to decrease by 25% due to greater electric vehicle adoption.

New York City’s 80x50 Plan proposes to cut emissions by 80% by 2050 through state-wide grid emission reduction, increased electric vehicle uptake due to the 2035 ban on the sale of gasoline-powered cars, increased investment in public transit, and other initiatives such as instituting a congestion charge for cars in 2024.

One of New York’s greatest assets is its comprehensive public transit network, which offers buses, trains, metro, trams, and ferries. Starting in July 2023, New York’s Metropolitan Transportation Authority (MTA), its public transit operator, kicked off a $35 million project to expand 12 subway lines. The MTA has plans both to increase frequency of trips on current lines and improve subway station infrastructure. New York also is expanding some incentive programs, like temporarily offering various free bus service lines across the city.

However, New York’s commitments to address transport emissions are still roughly 0.8 MtCO2e short of the target, requiring an additional 30% decrease in emissions on top of current government commitments by 2030 to stay within 1.5°C of warming.

Optimization

How New York can reach the 1.5°C climate change target by 2030

We explored four different optimization scenarios:

  • Default: Minimizes mobility behavior changes
  • Electrification: Accelerates the transition from gasoline and diesel vehicles to electric vehicles
  • Multimodal: Encourages the use of shared services and public transit
  • Active Mobility: Promotes walking and cycling as alternative modes of transport

All the optimization scenarios get New York to the 1.5°C target, but to do so requires significant shifts in behavior or reductions in demand. For example, the active mobility scenario would require each person to walk an additional six kilometers, or four miles, per day. The electrification and multimodal scenarios are the best fit for New York, due to the strong public transit infrastructure and a power grid that is transitioning to sustainable energy.

Modal Shifts Required To Achieve 1.5°C (By Scenario)

When simulating realistic modal shifts, achieving 1.5°C would not be possible. When allowing larger shifts, achieving 1.5°C would require extreme changes: a reduction in total mobility demand of 4% or approximately 1.1 kilometers (0.7 miles) per person per day compared to 2022.

Reduce personal car use:

  • Institute low-emission zones (beyond freight) and car-free areas
  • Introduce barriers to personal cars (for example, congestion pricing, limited parking)

Increase active mobility such as cycling:

  • Promote active mobility by implementing the 15-minute city concept
  • Continue NYC DOT investments in cycling infrastructure and build on bicycle sharing programs like CitiBike by pushing for improved incentives and expanding the network

Promote shared mobility:

  • Increase the number of shared mobility car, and moped providers while incentivizing these services

Modal Shifts Required To Achieve 1.5°C (By Scenario)

When simulating realistic modal shifts, achieving 1.5°C would be possible, requiring a reduction in total mobility demand of 2% or approximately 0.8 kilometers (0.5 miles) per person per day compared to 2022.

Reduce personal car use:

  • Institute low-emission zones (beyond freight) and car-free areas
  • Introduce barriers to personal cars (for example, congestion pricing, limited parking)

Accelerate electrification of the fleet:

  • Accelerate fleet electrification (cars and buses) to swiftly achieve the NYC Clean Fleet Plan goal of 50% reduction in greenhouse gas emissions by 2025 and 80% by 2035 from a 2005 baseline

Increase active mobility:

  • Promote active mobility by implementing the 15-minute city concept
  • Continue investing in cycling road infrastructure and bicycle sharing programs through “super sidewalks”

When simulating realistic modal shifts, achieving 1.5°C would not be possible. When allowing larger shifts, achieving 1.5°C would require extreme changes: a reduction in total mobility demand of 4% or approximately 1.1 kilometers (0.7 miles) per person per day compared to 2022.

Modal Shifts Required To Achieve 1.5°C (By Scenario)

When simulating realistic modal shifts, achieving 1.5°C would not be possible. When allowing larger shifts, achieving 1.5°C would not require a reduction in total mobility demand but would require extreme increases in active mobility compared to 2022.

Reduce personal car use:

  • Institute low-emission zones (beyond freight) and car-free areas
  • Introduce barriers to personal cars (for example, congestion pricing, limited parking)

Increase cycling:

  • Promote active mobility by implementing the 15-minute city concept
  • Continue investing in cycling road infrastructure and bicycle sharing programs through “super sidewalks”

Increase walking:

  • Continue investing in walking infrastructure, promoting pedestrian safety, and ensuring accessibility to all
