The Greater New Haven Clean Cities Coalition, Inc. (GNHCCC) is a 501(c)(3) non-profit organization that furthers the use of alternative fuels and advanced technology vehicles. We were first designated a U.S. Department of Energy (DOE) Clean Cities Coalition in October 1995. The GNHCCC covers New Haven County and other areas of Connecticut as it handles federal grant projects.
The GNHCCC brings together stakeholders in the public and private sectors to deploy alternative and renewable fuels, idle-reduction measures, fuel economy improvements, and emerging transportation technologies. The goal is to improve air quality, support economic development, increase energy security, and reduce dependence on petroleum. We do this by providing education and training, technical expertise, networking opportunities, and funding assistance to our stakeholders.
Over 20 Years of AdvancementGNHCCC was designated in October of 1995 as a coalition of the U.S. Department of Energy’s Clean Cities Program.
Nationally, there are nearly 100 Clean Cities coalitions that advance the nation’s economic, environmental, and energy security by supporting local actions to reduce greenhouse gas (GHG) emissions and cut petroleum use in transportation.

Why Clean Cities?
The United States relies heavily on foreign oil to power its transportation sector. Our country imported about 40% of the petroleum it consumed in 2012, and about two-thirds of these imports came from outside North America, according to the U.S. Energy Information Administration.
Support U.S. Economy and Energy SecurityTransportation accounts for about 71% of U.S. petroleum consumption
Reduce emissions impacting air quality and public healthGasoline- and diesel-powered vehicles are major sources of greenhouse gases, smog-forming compounds, particulate matter, and other air pollutants
Lee started the New Haven Clean Cities coalition in 1995 and has served as the coalition’s coordinator for the last 17 years.
Paul worked his way up from Clean Cities stakeholder to board member to co-coordinator.
GNHCCC StakeholdersAlmost 18,000 stakeholders contribute to Clean Cities’ goals and accomplishments through participation in nearly 100 Clean Cities coalitions across the country. Private companies, fuel suppliers, local governments, vehicle manufacturers, national laboratories, state and federal government agencies, and other organizations join together under Clean Cities to implement alternative-transportation solutions in their communities.

We work with fleets of all vehicle sizes, vehicle numbers, and vocations to find ways to reduce petroleum consumption through the use of alternative and renewable fuels, advanced vehicles, and other fuel-saving measures.
Alternative and Renewable Fuels
Many different fuel options exist which can help displace petroleum consumption and reduce emissions. These fuels are defined in the Energy Policy Act of 1992 (EPAct) including biodiesel, electricity, ethanol, hydrogen, natural gas, propane. Alternative fuels may include both renewable and non-renewable fuels, and interest in their use is expanding among the general public as well as large fleets. Although availability of different fuels has sometimes been a challenge in the past, refueling infrastructure is expanding throughout the country and specifically Connecticut to meet the growing demand.
Electricity can be used to power all-electric vehicles and plug-in hybrid electric vehicles. These vehicles can draw electricity directly from the grid and other off-board electrical power sources and store it in batteries. Hybrid electric vehicles use electricity to boost fuel efficiency. Using electricity to power vehicles can have significant energy security and emissions benefits. To find out more about powering cars with electricity, visit the US Department of Energy’s electricity website or you can download a PDF fact sheet to print out.
Natural gas is a domestically produced gaseous fuel, readily available through the utility infrastructure. This clean-burning alternative fuel can be used in vehicles as either compressed natural gas (CNG), liquefied natural gas (LNG), renewable natural gas (RNG), or biogas. To find out more about natural gas, visit the US Department of Energy’s natural gas website or you can download a PDF fact sheet to print out.
Propane, also known as liquefied petroleum gas (LPG) or propane autogas, has been used worldwide as a vehicle fuel for decades. It is stored as a liquid, and propane fueling infrastructure is widespread.

Alternative Fuel Vehicles
As vehicle technology continues to advance, the variety of vehicle types available is increasing rapidly. Consumers and fleets can now choose to purchase vehicles that use an alternative fuel, an advanced hybrid powertrain, all-electric vehicles, energy-efficient diesel, or simply a highly efficient conventional gasoline engine. More choices, such as fuel-cell vehicles are on the horizon. The Department of Energy provides a list of energy-efficient technologies that are offered on many vehicles available today. AFVs are available either as conversions or as original manufacturer equipment, and come in both light-duty passenger vehicles and heavy-duty vehicles and equipment. Alternative fuel vehicles (AFVs), as defined by the EPAct, include any dedicated, flexible-fuel, bi-fuel, or dual-fuel vehicle designed to operate on at least one alternative fuel. To the right are the definitions of each type.
DedicatedDesigned to run only on the alternative fuel.
Flexible-fuelCapable of operating on gasoline, E85, or a mixture of the two.
Bi-fuelDesigned with two separate fueling systems that allows for operation on natural gas or propane and conventional gasoline.
Dual-fuelRequires both alternative fuel and diesel fuel storage and delivery systems. Mainly developed for heavy-duty applications-usually out of warranty.
GNHCCC and its stakeholders have received several grants throughout the past few years! Click on the tabs below to find out what projects are being funded thanks to these awards.
