Pittsburgh Regional Transit is building on ten years of sustainability initiatives to establish the agency's first climate action plan. This document will be a roadmap for how PRT reduces its greenhouse gas emissions to zero by 2045. Check back this spring for more information and to follow our progress as we start to implement the plan.

Help us implement the plan!

PRT is hiring its first Sustainability Director to coordinate Climate Action Plan implementation. We are planning great things and need your help!

Climate action plans (CAPs) are documents that detail the sources of greenhouse gas (GHG) emissions of an organization or municipality, set targets for reducing those emissions over time, and establish goals, strategies, and actions that will be taken to meet those reduction targets.

Yes! Riding transit is one of the most impactful actions an individual can take to reduce their contribution to climate change. Investments in transit are also one of the top actions that the federal, state, and local governments can take to reduce transportation-related emissions. The intent of transit agencies creating Climate Action Plans is to recognize that the service we provide fights climate change, but it also comes with its own emissions that we can eliminate through the vehicles and electricity we purchase, and how we operate as a large government entity. PRT's Climate Action Plan will focus on reducing greenhouse gas emissions (GHGs), but will also include other actions that allow us to help the region become more sustainable including better management of our stormwater, waste, and energy.

The largest source of our emissions is from the burning of fossil fuel diesel in our 722 buses. These emissions are far less than what would happen if all our riders drove gasoline fueled cars or even electric vehicles, but they can still be eliminated. PRT's 2021 long-range plan, NEXTransit, committed the agency to transitioning to a zero emission fleet by 2045. PRT put its first battery electric buses into service in 2022 and is developing a plan to transition the entire fleet to this technology or others such as hydrogen fuel cells to meet our adopted goal.


PRT has many buildings throughout Allegheny County that use a significant quantity of electricity. These buildings can be more efficient through new systems and practices, but we are also committed to transitioning the source of our electricity to low or no emission sources. Another significant use of energy is our fully electric light rail vehicle fleet. As PRT replaces rail cars and improves light rail infrastructure, we can reduce our energy consumption.


Buildings and vehicles require refrigerants to operate and maintain comfortable temperatures. Refrigerant use and leaks are relatively small but have a significant impact on climate change and must be managed.

Other Vehicles

It takes a lot of work to keep our transit system operating and safe. PRT's non-revenue fleet vehicles include police cars, pool cars, various classes of trucks, construction and other maintenance vehicles. Their emissions can be addressed by careful management that reduces the need for heavy duty vehicles and transitioning to low or zero emission technologies as they become available.

Scope 3 Emissions

PRT's first Climate Action Plan is focused on the emissions we are directly responsible for which is largely the fuels we burn, the electricity we use, and our refrigerants. These are referred to as Scope 1 and 2 emissions. Scope 3 emissions that are due to services and the production of goods PRT uses. PRT is working to better capture information about these emissions to inform the next update to our greenhouse gas (GHG) inventory and the actions in our next plan.
