Sustainability In The Accounting Industry Statistics

Accounting firms are cutting their own emissions while also stepping up the harder parts of sustainability work, from a 28% Scope 1 drop over 2019 to 2023 and Scope 2 purchased-energy emissions down 51% from 2020 to 2023 to remote auditing saving 1.2 million tons of CO2e across the sector in 2023. The page puts that progress under pressure with measurable gaps and knock-on effects, including only 22% full compliance with TCFD recommendations among mid-tier firms and rapidly expanding ESG verification, risk modeling, and nature and human rights disclosures.

Accounting firms have cut their own operational emissions by 28% on average from 2019 to 2023, but the bigger shift is happening in how work is done and verified. Remote auditing alone saved 1.2 million tons of CO2 equivalent in 2023, while renewable cloud deployments reduced data center energy use by 53%. The result is a sector where sustainability is no longer a side project but something measured across offices, fleets, suppliers, and even assurance standards.
