The United States is the single largest market for environmental technologies in the world, making up 25% of the $1.2 trillion global market. The industry is composed of around 114,000 enterprises and 1.6 million workers. As of 2021, the U.S. market was valued at $552.1 billion, with services accounting for 55%, equipment for 21%, and resources for 24%.

Small and medium-sized businesses make up the majority of the industry, accounting for 99 percent of private sector activity. Despite this, they generate only 18 percent of the total revenue. In contrast, large companies represent just 1 percent of the private sector but generate 44 percent of the revenue. Public-sector municipalities and similar entities dominate water utilities, wastewater treatment works, and solid waste management, making up the remaining 38 percent of the industry.

The environmental technology industry in the United States has seen significant growth over the past 15 years, despite undergoing restructuring and consolidation. This change in ownership and structure is expected to continue, particularly in the water sector where investment opportunities are available due to gaps in infrastructure.
