The Truck and Engine Manufacturers Association (EMA) is a not-for-profit trade association that represents worldwide manufacturers of internal combustion engines and on-highway medium- and heavy-duty trucks. EMA works with government and industry to help the nation achieve its goals of cleaner air and safer highways and to ensure that environmental and safety standards and regulations are technologically feasible cost-effective, and provide safety and environmental benefits.
Our members manufacture internal combustion engines that are used in a wide variety of applications, including:
Trucks and buses
Farm, construction, and industrial equipment
Lawn, garden and utility equipment, and
Electric generators, and other stationary applications
Our members also manufacture medium and heavy-duty trucks with gross vehicle weight ratings (GVWR) over 10,000 pounds.
EMA serves as the voice of its 28 member companies on domestic and international public policy, legislative and regulatory issues. The Association works cooperatively with regulatory agencies, including the US Environmental Protection Agency (EPA), the California Air Resources Board (ARB), the National Highway Transportation Safety Administration (NHTSA), state governments and international regulatory agencies to develop and implement cost-effective and technologically feasible emissions, fuel efficiency and safety regulations that result in fewer emissions, better fuel efficiency, and enhanced safety.
Tracing its roots back to 1968, EMA's members include the leading engine and truck manufacturers from the United States, Europe, and Japan. As a member-driven trade association, the management of EMA is based on a committee structure that includes a Board of Directors composed of a representative from each member company, an Executive Committee appointed by the members to direct and manage EMA activities, and a series of committees that are organized along major engine and truck product-lines, such as heavy-duty on-highway trucks and buses, nonroad mobile equipment, marine and locomotives engines, grounds care and utility equipment, stationary engines, and fuels. Each committee is comprised of member company representatives.
Association operations are carried out by a small staff of professional and administrative personnel who represent and promote EMA positions with various outside organizations and government regulators. EMA is based in Chicago with a satellite international office in Germany.
EMA also sponsors scientific and technical research to improve engine and truck performance, reduce emissions, improve safety develop more accurate measurement and testing methods, assure the improvement and compatibility of fuels, and to improve the overall l performance of advanced engine and truck technologies.
Through research, development, and advocacy, EMA members have successfully worked with government and regulatory agencies to reduce emissions from internal combustion engines by over 99% since EMA was formed over 40 years ago. The Truck and Engine Manufacturers Association works with government and industry to help achieve the nation's goals of cleaner air and safer highways, and to ensure that environmental and safety standards and regulations are technologically feasible, cost-effective, and provide safety and environmental benefits.
