ERM

What ERM does

ERM is the world's largest pure-play sustainability consultancy, founded in 1971 and headquartered in London (with primary US operations in Malvern). The firm delivers environmental, health, safety, risk, social, and sustainability advisory services to global corporations, governments, and institutions across chemical, financial services, manufacturing, mining, oil & gas, power, renewables, technology, and pharmaceutical industries. Notable operational credentials include advising on 95% of the world's largest LNG projects, supporting $85B+ in LNG project-finance debt, and permitting 8,074 km of pipeline.

ERM operates a platform-plus-services model combining strategic consulting with proprietary technology products. Core branded platforms include ERM Libryo (cloud-based regulatory compliance management acquired in 2022), emissions.AI (AI-driven emissions analytics acquired via OPEX Group in 2021), the Carbon Credit Portal (launched 2024 for voluntary carbon market project evaluation), and ERM CVS (independent assurance and certification). Sub-brands such as the Sustainability Institute, Council on Sustainability Transformation, and ERM Foundation support thought leadership and ecosystem influence.

The firm generates revenue through project-based professional services engagements, typically multi-year, priced by scope and complexity under direct enterprise sales relationships. Distribution is exclusively direct: senior relationship managers and multi-disciplinary teams engage clients in 40 countries. ERM has scaled through an aggressive acquisition program — completing roughly 20 deals since 2011 — and has expanded its technology stack via partnerships with Carbmee, Jupiter Intelligence, Ecolumix, CEEZER, and Natcap. Ownership remains private under The ERM International Group Limited, with no disclosed institutional investors or public listing.
