Sustainable Consulting Global Market Report 2025

The sustainable consulting market size has grown rapidly in recent years. It will grow from $13.95 billion in 2024 to $15.35 billion in 2025 at a compound annual growth rate (CAGR) of 10.1%. The growth during the historic period can be attributed to regulatory compliance pressures, corporate social responsibility efforts, heightened environmental awareness, increased stakeholder scrutiny, and early adoption by large enterprises.

The sustainable consulting market size is expected to see strong growth in the next few years. It will grow to $22.3 billion in 2029 at a compound annual growth rate (CAGR) of 9.8%. The growth projected for the forecast period is driven by carbon neutrality goals, expansion of ESG investments, integration of green supply chains, climate risk disclosure mandates, and net-zero policy requirements. Key trends expected in the forecast period include AI-powered sustainability analytics, alignment with circular economy strategies, an emphasis on biodiversity and natural capital, growing demand for scope 3 emissions consulting, and the emergence of sustainability-as-a-service platforms.

The increasing emphasis on environmental, social, and governance (ESG) investing is expected to drive the expansion of the sustainable consulting market going forward. ESG investing is an approach that evaluates a company’s environmental impact, social responsibility, and governance practices alongside its financial performance when making investment decisions. This growing focus on ESG investing is largely due to heightened awareness among investors regarding the long-term financial and reputational advantages of supporting sustainable, ethical, and socially responsible business conduct. Sustainable consulting facilitates ESG investing by offering expert advice and data-driven strategies that align ESG practices with sustainable financial outcomes. For example, a report by Bankrate, LLC, a US-based financial service firm, in January 2023 highlighted a significant rise in interest in ESG investing in recent years as more investors emphasize the social and environmental impact of their investments. By the end of 2022, global ESG fund assets had increased to roughly $2.5 trillion, up from $2.24 trillion at the end of Q3. Consequently, the growing focus on ESG investing is propelling the sustainable consulting market’s growth.

Leading companies in the sustainable consulting market are concentrating on developing innovative solutions such as integrated ESG platforms to assist clients in streamlining reporting, enhancing compliance, and efficiently achieving sustainability objectives. Integrated ESG platforms are digital systems that consolidate environmental, social, and governance data into one tool for monitoring, reporting, and analysis. These platforms support sustainability consultancies by enabling more precise assessments, efficient reporting, and data-driven strategies that help clients meet regulatory and sustainability goals. For instance, in February 2025, HPX Group, a professional services firm based in Australia, launched Materra, a specialized ESG and sustainability consultancy providing comprehensive services in sustainability strategy, ESG compliance, climate change advisory, and sustainable finance. The firm is led by Linda Romanovska, a former RSM partner and recognized expert in sustainable finance and corporate sustainability, with extensive experience from PwC and various government and nonprofit roles. Materra aims to assist businesses in navigating changing ESG regulations, improving investor relations, and integrating long-term sustainability objectives into their core operations by delivering practical, tailored strategies.
