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 Advancement
GNHCCC 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 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 Security
Transportation accounts for about 71% of U.S. petroleum consumption
Reduce emissions impacting air quality and public health
Gasoline- 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.
As part of his Clean Cities mission, Grannis has developed projects and obtained federal and matching funding for compressed natural gas, liquefied natural gas, light duty electric vehicles, electric transit, hydrogen hybrid, and biodiesel projects, and related outreach project funding. He has provided alternative vehicle and fuel consultation and assistance to many organizations in Connecticut and outside the state, including several towns and cities, metropolitan transit authorities, utilities, community colleges, universities, laboratories, and airports. He serves as an on-call advisor to Connecticut state government staff and Connecticut’s U.S. Congressional and Senatorial staff. Recently, his coalition, in partnership with the three other Connecticut Clean Cities coalitions and 27 other partners, was awarded $29 million (including partner match) from the U.S. Department of Energy for alternative fuel infrastructure and vehicle deployment in Connecticut. Grannis was selected as the Northeast Region Clean Cities Coordinator of the Year in 2004 and 2008 and was inducted into the national Clean Cities Hall of Fame in 2012. Grannis retired after 23 years as a lieutenant colonel infantry from the U.S. Army. He held several combat and logistical positions, which included two combat tours in Vietnam. He attended several military schools and is a graduate of the U.S. Army Command and General Staff College. Grannis has a Bachelor of Arts Degree from Eastern Kentucky University in Political Science and a Master of Arts in Public Administration from Central Michigan University.
Paul worked his way up from Clean Cities stakeholder to board member to co-coordinator.
Wessel leads the Green Parking Council, a national 501(c)(3) organization fostering green parking practices through certification and credentialing programs, open-sourced standards, professional leadership and educational development. He was previously Deputy Economic Development Administrator and Director of Traffic & Parking for the City of New Haven, CT and served on the boards of the New Haven Parking Authority, the Greater New Haven Transit District and Greater New Haven Clean Cities. Under his leadership, New Haven introduced electric vehicle shuttle buses, upgraded parking enforcement and meter technology and increased parking revenue dramatically. He has experience in legislative and community advocacy, municipal economic development, engaging foundations and non-profits in community development and developing public-private partnerships. Wessel has a M.S. in Urban Policy Analysis and Management from New School University and a B.A. in History from Wesleyan University.
Almost 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.
Biodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant grease for use in diesel vehicles. Biodiesel’s physical properties are similar to those of petroleum diesel, but it is a cleaner-burning alternative. Using biodiesel in place of petroleum diesel, especially in older vehicles, can reduce emissions. To find out more about biodiesel, visit the US Department of Energy’s biodiesel 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.
Designed to run only on the alternative fuel.
Capable of operating on gasoline, E85, or a mixture of the two.
Designed with two separate fueling systems that allows for operation on natural gas or propane and conventional gasoline.
Requires both alternative fuel and diesel fuel storage and delivery systems. Mainly developed for heavy-duty applications-usually out of warranty.
