Tamtam tracks 2,448 environmental services companies headquartered in Europe. This list ranks the 100 largest by number of employees on LinkedIn, led by FCC, Veolia and ACCIONA. Their median headcount is 4,260. Half of them were founded in 1963 or later. The most common headquarters are Madrid (10), London (6) and Paris (4).

These are large environmental services companies in Europe, focusing on waste management, water solutions, and sustainable infrastructure. Key players include Veolia, which works on environmental security and resource regeneration, and SUEZ, providing water and waste management.

The companies listed are predominantly large groups, many with a long history of operation, such as FCC (founded 1900) and Veolia (founded 1853).

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
