Grants and Fellowship Information

National Clean Diesel Campaign (NCDC)

  • Grants and Funding Overview - Tribal Grants and Funding Overview
  • EPA's National Clean Diesel Funding Assistance Program awards competitive grants to fund projects that implement EPA or CARB verified and certified diesel emission reduction technologies.
  • EPA's Clean Diesel Emerging Technologies Program provides an opportunity to foster the development of cutting-edge technologies to reduce emissions from the existing fleet of heavy-duty diesel engines. The program promotes the deployment of innovative technologies by providing funding to develop and evaluate these technologies in the field.
  • EPA's SmartWay Clean Diesel Program issues competitive grants to establish national low-cost revolving loans or other financing programs that help fleets reduce diesel emissions.
  • EPA's State Grant Program allocates funds to participating states to implement grant and loan programs for clean diesel projects. Base funding is distributed to states using a specific formula based on participation, and incentive funding is available for any states that match their base funding.

Landfill Methane Outreach Program

EPA's Landfill Methane Outreach Program (LMOP) is a voluntary assistance program that helps to reduce methane emissions from landfills by encouraging the recovery and beneficial use of landfill gas (LFG) as an energy resource. While LFG recovery offers significant environmental, energy, and economic benefits to the public and private sector, there are still barriers to project development. The LMOP Funding Guide focuses on one barrier in particular: financing for LFG energy project development. Included in the guide are many innovative funding programs and strategies that can help developers overcome financial barriers. These programs and strategies include, among other things, loans, grants, renewable portfolio standards, renewable energy trust funds, and property, sales, and use tax exemptions.

Water & Energy Efficiency in Water and Wastewater Facilities

Reducing energy use at drinking water and wastewater systems reduces the emission of greenhouse gases. Upgrading and retrofitting for energy conservation can be expensive for any size facility, and may seem out of reach for small communities. This EPA site provides funding opportunities from federal, state, and private sources, including grants, loans, renewable credits, rebates, stand-by and other special rates for energy conservation practices at water and wastewater facilities.

SmartWay Innovative Financing

The SmartWay Clean Diesel Finance program aims to accelerate the deployment of energy efficient and emission control technologies by helping vehicle/equipment owners overcome financial obstacles. SmartWay also provides a financial clearinghouse web site with access to private lenders who help carriers obtain a loan for a SmartWay Certified Tractor, SmartWay Certified Trailer or SmartWay approved fuel savings and emissions reducing technologies. The purpose of this site is to efficiently and conveniently disseminate information on financing that is available for purchasing cleaner trucks and trailers, and emissions reducing and fuel saving technologies (such as auxiliary power units). All loan information contained in this site represents private company loans. These are not Federal government loans.

Smart Growth

The EPA Smart Growth program sometimes offers grants to support activities that improve the quality of development and protect human health and the environment.

Partnership for Sustainable Communities

The Partnership for Sustainable Communities, a partnership between the U.S. Department of Housing and Urban Development (HUD), U.S. Department of Transportation (DOT), and US EPA, works to coordinate federal housing, transportation, water, and other infrastructure investments to make neighborhoods more prosperous, allow people to live closer to jobs, save households time and money, and reduce pollution. The partnership agencies incorporate six principles of livability into federal funding programs, policies, and future legislative proposals.

US Climate Change Technology Program

The US Climate Change Technology Program is a multi-agency research and development program for the development of climate change technology.

Department of Energy (DOE)

Advanced Research Projects Agency—Energy (ARPA-E)

  • ARPA-E Funding Opportunities
    ARPA-E is modeled after the successful Defense Advanced Research Projects Agency (DARPA). ARPA-E is charged with the following objectives: to bring a freshness, excitement, and sense of mission to energy research; focus on creative “out-of-the-box” transformational energy research; utilize an ARPA-like organization; and create a new tool to bridge the gap between basic energy research and development/industrial innovation.

Office of Energy Efficiency and Renewable Energy (EERE)

The Office of Energy Efficiency and Renewable Energy (EERE) works with business, industry, universities, and others to increase the use of renewable energy and energy efficiency technologies. One way EERE encourages the growth of these technologies is by offering financial assistance opportunities for their development and demonstration.

Clean Cities

Securing funding is critical to the success of efforts to reduce petroleum use in transportation. Financial opportunities for Clean Cities projects are available from many sources inside and outside the U.S. Department of Energy (DOE).

Database of State Incentives for Renewables and Efficiency (DSIRE)

Incentives and policies for renewables & efficiency in Arizona, California, Hawaii, and Nevada.

Tribal Energy Program

The Tribal Energy Program promotes tribal energy sufficiency, and fosters economic development and employment on tribal lands through the use of renewable energy and energy efficiency technologies.

Loan Programs Office (LPO)

The Department of Energy’s Loan Programs—administered by LPO—enable DOE to work with private companies and lenders to mitigate the financing risks associated with clean energy projects, and thereby encourage their development on a broader and much-needed scale. The Loan Programs consist of three separate programs managed by two offices, the Loan Guarantee Program Office (LGP) and the Advanced Technology Vehicles Manufacturing Loan Program Office.

U.S. Small Business Administration (SBA)

Small Business Innovation Research (SBIR) Program

SBA's Office of Technology administers the Small Business Innovation Research (SBIR) Program and the Small Business Technology Transfer (STTR) Program. Through these two competitive programs, SBA ensures that the nation's small, high-tech, innovative businesses are a significant part of the federal government's research and development efforts. Eleven federal departments participate in the SBIR program; five departments participate in the STTR program awarding $2billion to small high-tech businesses. The U.S National Science Foundation administers the SBIR.GOV site on behalf of the federal government.

Federal Agency SBIR Links

Find links to SBIR programs at federal agencies including the Department of Agriculture, Department of Commerce, Department of Defense, Department of Energy, Department of Transportation, and US Environmental Protection Agency.

Department of Transportation (DOT)

Reducing pollution and other adverse environmental effects of transportation projects and transportation system inefficiency have been long‐standing DOT objectives.

Congestion Mitigation and Air Quality (CMAQ) Program

The CMAQ program supports transportation projects or programs that will improve air quality and relieve congestion in areas that do not meet National Ambient Air Quality Standards. CMAQ funds may be used to establish new or expanded transportation projects or programs that reduce emissions, including capital investments in transportation infrastructure, congestion relief efforts, and diesel engine retrofits. Other CMAQ projects include operating assistance for new transit services, travel demand management strategies, traffic flow improvement programs that reduce emissions, and bicycle/pedestrian facilities and programs.
