Environmental Technology Spotlight

The Environmental Technology Industry in the United States


The United States is the single largest market for environmental technologies in the world, representing nearly a third of the $1.2 trillion global market. According to Environmental Business International, Inc., approximately 114,000 enterprises and 1.6 million workers make up the U.S. environmental technology industry. In 2018, the total U.S. market was estimated at $342 billion, with approximately 54 percent from services, 21 percent from equipment, and 25 percent from resources.

Small and medium-sized businesses account for 99 percent of the industry and generate approximately 20 percent of the total revenue. Large companies represent only 1 percent of private sector activity, yet account for 46 percent of revenue. Public-sector municipalities and similar entities make up the remaining 34 percent and dominate water utilities, wastewater treatment works and solid waste management.

The U.S. environmental technology industry has undergone significant restructuring and consolidation but has experienced growth over the past 15 years. Change of ownership and structure within environmental technology businesses is expected to continue, particularly in the water sector where the gap in infrastructure investment, offers significant investment opportunities.

Industry Subsectors

Water: The water sector encompasses potable water provision and wastewater treatment industries, with key segments including municipal drinking water delivery and treatment, municipal wastewater conveyance and treatment, ground and surface water remediation, industrial process water treatment, and industrial wastewater treatment. According to the American Water Works Association (AWWA), water utility management is relatively dispersed in the United States, with 3,900 utilities supplying about 80 percent of the nation's drinking water and treating almost half of all wastewater. Ownership structure vary from private concerns to state or municipally owned and operated facilities, with approximately 90 percent of all drinking water service, provided by public utilities.  Water consumption is declining in the United States based on increasing efficiencies in water management both at water utilities and by users. However, significant investment will be needed in the coming decades to maintain the quality of drinking water and continuing improvements in waste water management. Drinking water is delivered via one million miles of pipes across the country. Many of those pipes were laid in the early to mid-20th century, with a lifespan of 75 to 100 years. As a result, there are significant opportunities for investment in the subsector, with the AWWA estimating $1 trillion in public and private funds required to maintain and expand services to meet demand over the next 25 years.

Air Pollution Control & Monitoring: This subsector includes air pollution monitoring and control technologies for both stationary and mobile pollution sources. Stationary sources include emissions from thermal energy generation and industrial sources such as boilers, incinerators and smelters. Primary industries for air pollution monitoring and control include electricity, mining, cement, oil and gas refineries, and chemicals. There have been significant improvements in U.S. air quality over the last several decades. According to the U.S. Environmental Protection Agency, since 1970, aggregate U.S. emissions of six key air pollutants dropped by an average of 70 percent. The International Clean Air Coalition estimated the U.S. stationary air emissions control market at $16 billion in 2016.

Waste Management & Recycling: This subsector includes solid and hazardous waste management, recycling and resource recovery, and soil pollution prevention and remediation technologies. The technologies needed by this sector depend on the composition and properties of the waste generated. The recycling industry is driven by demand from the materials markets, and its growth is dependent on the price of raw materials.
