The report is based on data compiled for 35 of the leading international E&S consulting firms, who totaled a combined revenue of $35.3bn in 2023, and together account for 65% of the global E&S consulting market.

The latest data from the Global 35, or ‘G35’, leading companies featured in the report is based on their figures for the latest fiscal year end, submitted via an annual survey and verification process (and/or estimated based on publicly available annual reports and public information sources where there are data gaps). For all the G35 firms analysed, the data is based on their financial year ending in 2023 (2024 for the companies with FY ending in March).

Environment Analyst’s definition of environmental sustainability consulting (E&S) is: “The provision of specialist technical, management, risk, analytics and strategic advisory services to help organisations understand, manage, and minimise their impacts to protect and enhance the environment and communities, and proactively respond to climate change, the nature crisis and associated impacts”.

We are proud to be included in this leading global 35 ranking by EA, and more importantly, proud of the work this represents globally for our clients in accelerating a more sustainable future for all.
