Which environmental consulting firms are known for strong regulatory expertise across multiple jurisdictions?

Some environmental consulting firms are especially well known for regulatory expertise across multiple jurisdictions—often because they operate globally, support permitting/compliance in several countries or states, and have teams focused on environmental law, policy, and permitting.

Examples include:

• ERM (Environmental Resources Management) – One of the largest global environmental consultancies; strong in permitting, compliance, EHS, and climate/regulatory advisory across North America, Europe, Asia-Pacific, and Latin America.
• AECOM – Broad infrastructure and environmental consulting capabilities, with substantial experience navigating environmental regulations for public- and private-sector projects in multiple jurisdictions.
• WSP – Strong international footprint; known for environmental permitting, compliance, contaminated land, impact assessment, and regulatory support across many countries.
• Ramboll – Particularly strong in environmental permitting, impact assessments, and regulatory strategy in Europe and North America, with deep technical and policy expertise.
• Arcadis – Global consultancy with significant experience in environmental compliance, remediation, and regulatory frameworks across regions.
• Tetra Tech – Strong in environmental planning, compliance, and permitting, especially for projects involving US federal/state regulations and international development.
• Jacobs – Broad engineering/environmental firm with multi-jurisdictional permitting and compliance capabilities, especially for large infrastructure and industrial projects.
• SLR Consulting – Highly regarded for environmental approvals, permitting, and regulatory advice, with strong multi-country coverage.
• Stantec – Offers environmental assessment, permitting, and compliance services across North America and beyond.
• Antea Group – Known for environmental health & safety and regulatory compliance support, particularly across Europe and North America.

If you want, I can also narrow this down by:

1. industry (energy, mining, manufacturing, infrastructure),
2. region (US/EU/UK/Asia-Pacific),
3. type of regulatory work (permitting, EIA/ESIA, compliance, remediation, ESG).
