ERM Global

What ERM Global does

ERM Global (legal entity The ERM International Group Limited) is a London-headquartered, privately held sustainability consultancy founded in 1971, operating with people in over 38 countries and self-described as the world's largest pure-play sustainability consultancy. Its core service offering spans environmental, health, safety, risk, and social consulting, with practice areas including climate and net zero strategy, EHS management, energy transition, nature and water, capital project permitting, sustainable finance, reporting and disclosure (CSRD, SEC, TCFD, TNFD), supply chain decarbonization, and product stewardship. The firm's go-to-market is enterprise field sales to large multinationals, capital project developers, financial institutions, and sector-specific verticals (Energy, Mining & Metals, Chemicals, Pharma, TMT), with engagements structured as multi-year project or retainer-based professional services contracts priced by scope and team composition.

Beyond consulting, ERM has built a portfolio of technology-enabled offerings: ERM Libryo (sustainability compliance and reporting software), ERM CVS (independent assurance and certification), the Carbon Credit Portal (digital marketplace for carbon credit selection, purchase, and retirement), the ERM Sustainability Institute (research and thought leadership platform), and the Rate the Raters initiative (independent ESG ratings research). Distribution relies on direct consulting engagement teams supported by an extensive thought-leadership engine comprising the Annual Trends Report, Quarterly Trends Report, Global Regulations Radar, the 42+ episode Sustainable Connections podcast, and active participation in COP, Climate Week NYC, and London Climate Action Week. Documented scale signals include partnerships with 95% of the world's largest LNG projects, advisory support on over $85 billion in LNG project-finance debt, and 8,074 km of pipeline permitted. Strategic positioning is anchored on being the largest pure-play, independently owned, multi-decade incumbent in a market being structurally expanded by regulation (CSRD, SEC climate disclosure, TNFD, UK SRS) and by enterprise net-zero commitments, with recent strategic moves focused on AI-enabled Scope 3 (Carbmee), nature and water solutions (Natcap), and supply chain decarbonization (Clean Heat Program with Secaro and AstraZeneca).
