Driving PA Forward
Cleaner Transportation for Cleaner Air

Reducing emissions from diesel engines is one of the most significant air quality challenges facing the Commonwealth of Pennsylvania.
The Driving PA Forward grant and rebate programs were developed to improve air quality statewide by driving transformation from older, high-polluting diesel engines to clean transportation technologies.
New engine technologies, including electric, compressed natural gas, propane, and clean diesel significantly reduce pollutants from freight and delivery trucks, transit and school buses, port cargo handling equipment, forklifts, tugboats, and freight switchers that rely on older diesel technology.
Clean air is the cornerstone of a clean, healthy environment. When Volkswagen cheated on its emissions equipment, it undermined that cornerstone. Through our new Driving PA Forward initiative, we will begin to remedy that by driving the transition towards advanced zero-emission and low-emission vehicles and accelerating the build-out of infrastructure necessary to support the next generation of transportation options.
Goals
According to the Environment Protection Agency (EPA) 2017 National Emissions Inventory, mobile sources (transportation) account for more than half of oxides of nitrogen (NOx) emissions in Pennsylvania (50.2 percent). NOx is a precursor in the formation of ground level ozone and fine particulate matter (PM2.5). At elevated levels, ground level ozone and PM2.5 adversely affect the environment and human health.

Health effects include premature death in people with heart or lung disease, nonfatal heart attacks, aggravated asthma, and increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing. At elevated levels, these pollutants damage vegetation, the diversity of ecosystems and building facades and monuments.
The goal of the Driving PA Forward Initiative is to substantially and permanently reduce lifetime NOx emissions from mobile sources of diesel emissions. Of the mobile source NOx emissions, diesel sources, including aviation, marine, and rail sources, account for almost 57 percent of the mobile source NOx emissions.
Health Benefits
The transportation sector accounts for over 52 percent of total oxides of nitrogen (NOx) emissions in the United States. When NOx and volatile organic compounds combine in the presence of sunlight, ground level ozone is formed. Emissions of NOx can also act as precursors to the formation of fine particulate matter (PM2.5). Both ozone and PM2.5 pose significant risk to the health of the public and the welfare of the environment.
Breathing ozone can create a variety of health problems, especially for children, the elderly, and others with lung diseases such as asthma. Air containing ozone also affects people who are active outdoors, particularly those that work outside. Breathing ozone can cause chest pain, coughing, throat irritation, shortness of breath, and can reduce lung function and harm lung tissue. It can worsen bronchitis, asthma, and emphysema, and make the lungs more susceptible to infection. This leads to increased medical care, missed work and school, and the need for medication. For more information, see: EPA’s Health Effects of Ozone Pollution. For information on ozone nonattainment or maintenance areas in Pennsylvania, see EPA's Nonattainment for Criteria Pollutants (Green Book).
Exposure to PM2.5 can also create health problems, particularly for people with heart or lung disease, children, and older adults. Some impacts of PM2.5 exposure include premature death in people with heart or lung disease, heart attacks, irregular heartbeat, asthma, chronic obstructive pulmonary disease (COPD), and other symptoms of respiratory distress such as irritation of airways, wheezing, coughing, and shortness of breath. For more information, see EPA's Health and Environmental Effects of Particulate Matter (PM). For information on PM2.5 nonattainment or maintenance areas in or maintenance areas in Pennsylvania, see EPA's Nonattainment for Criteria Pollutants (Green Book).
According to the Pennsylvania Department of Health’s 2021 Asthma Prevalence Report, in their lifetime, one out of every six adult Pennsylvanians will be diagnosed with asthma. The American Lung Association estimated that asthma cost Americans approximately $60 billion in 2019- mostly due to costs associated with medical care, prescription medicines, and indirect costs like lost pay and commercial/industrial productivity.
- There are estimated to be 306,930 children in Pennsylvania who reported receiving an asthma diagnosis at some point in their lifetime.
- As of 2019, approximately one in eight children and one in six adult Pennsylvanians reported an asthma diagnosis at some point in their lifetime. This is currently higher than the per-capita asthma rate for the entire U.S.
- Lifetime asthma prevalence is highest among individuals living in low-income communities with an average, annual household income of less than $15,000. In many instances, low-income communities are located near high-pollution areas such as industrial/manufacturing facilities, freight distribution centers, railyards, and transportation corridors.

Driving PA Forward in Action
As of July 1, 2022, Driving PA Forward awarded over $70 million to nearly 1,100 diesel emissions reduction projects throughout Pennsylvania. Many of these projects are complete and already bringing real, tangible benefits and air quality improvements to communities across the Commonwealth.
Moreover, these completed projects have catalyzed additional diesel emissions reductions projects, as fleet operators and other stakeholders realize the environmental, health, and financial benefits to making similar fleet transitions. A great example of what the Driving PA Forward Program is doing to improve air quality in PA is this recently completed grant-funded project in Chambersburg, Franklin County .
Driving PA Forward: Improving Air Quality in Franklin County; heavy-duty truck, zero emission vehicle (HD-ZEV) replacement project
Of the $70 million awarded to-date, Driving PA Forward has already funded the installation of over 1,700 electric vehicle (EV) charging plugs in communities and along travel corridors, across the Commonwealth. By building out Pennsylvania’s network of Level 2 and DC fast chargers, Driving PA Forward is not just helping to expand a reliable charging network for existing light-duty EVs, but also encouraging large-scale adoption of light- to heavy-duty battery-electric and hybrid-electric vehicles.

Driving PA Forward: New Roads
Since the launch of the Driving PA Forward Initiative in 2018, consumers have demonstrated increasing interest in zero-emission transportation, and transportation markets in the Commonwealth have begun responding. With rising awareness of the growing climate change crisis and degraded air quality in their communities, many Pennsylvanians are starting to demand cleaner, more efficient zero-emission vehicle purchase options- not only for light-duty passenger cars and trucks, but also for medium- and heavy-duty commercial, industrial, and municipal vehicles. This is especially true for high-polluting, older diesel vehicles operating in priority areas, such as Environmental Justice Areas, which bear a disproportionate share of excessive diesel emissions from mobile sources in Pennsylvania.
Building on the continuing successes of the Driving PA Forward Initiative - and in response to the increased public demand to transition away from traditionally-fueled trucks to zero-emission technologies - the Wolf administration developed the Medium- and Heavy-Duty Zero-Emission Vehicle (MHD-ZEV) Fleet Pilot Grant Program.
MHD-ZEV Fleet
Electrifying Truck Fleets for Cleaner Air in Our Communities
Medium- & and Heavy-Duty Zero-Emissions (MHD-ZEV) Fleet Pilot Grant Program Initiative
DEP offered this $12.7 million competitive grant initiative to replace aging fleets of diesel-powered medium- and heavy-duty (MHD) local freight trucks with new zero-emission MHD local freight trucks, with top priority given to projects that serve Environmental Justice communities. For this grant, the term “local” is defined as operating predominantly within the Commonwealth of Pennsylvania.
Replacing aging diesel fleets with new zero-emission vehicles will reduce emissions by as much as 100 percent, helping to significantly improve air quality in communities that currently have some of the poorest air quality in Pennsylvania. It will also lead to savings in vehicle lifetime operating costs for fleet owners and operators.
Model year 1992–2009 Class 4–8 local freight trucks that operate predominantly in Pennsylvania are eligible for replacement. Eligible project vehicles must be replaced with new zero-emission trucks of similar class and vocation. After completing the project vehicle replacement phase, successful grantees will be required to collect operational data for their new zero-emission fleet vehicles for two years and provide the data to DEP for analysis. Funding applications will be evaluated and prioritized based on (but not limited to) the following criteria:
- Applicant status as a business, non-profit, government entity, planning organization, and Act 47 designee. An applicant’s performance for previous grant and rebate awards will also be considered.
- Proposed project fleet size and the degree to which the applicant will pilot new MHD-ZEV technologies in their operations.
- Project location, with priority given to areas that experience high levels of pollution – Environmental Justice Areas, EPA priority counties (National Ambient Air Quality Standards, or NAAQS), and high traffic density areas.
- Projected diesel emission reductions from the proposed project, with the focus being on NOx reductions.
- Cost-effectiveness of the project, in terms of grant dollars requested per ton of expected lifetime NOx reductions.
- Remaining useful life of the proposed project fleet vehicles, based on the applicant’s normal attrition schedule. Higher remaining useful life of vehicles leads to higher lifetime NOx reductions, and an increased cost-effectiveness score.
- The degree to which the applicant proposes to utilize Pennsylvania-based vendors and labor to complete their project.
- The quality and thoroughness of the applicant’s data collection and reporting plans.
Vehicles being replaced must be scrapped in accordance with Program Guidelines. Maximum reimbursement rates are defined in the Program Guidelines and in the Reimbursement Table linked below.
For more detailed information on the all-new MHD-ZEV Fleet Grant review the Program Guidelines and watch the short informational webinar posted below.
