The growing focus on environmental, social, and governance (ESG) investing is expected to drive the growth of the sustainable consulting market going forward. ESG investing refers to an investment approach that evaluates a company's environmental impact, social responsibility, and governance practices alongside its financial performance when making investment decisions. This growing focus is largely driven by increasing investor awareness of the long-term financial and reputational benefits of supporting sustainable, ethical, and socially responsible business practices. Sustainable consulting supports ESG investing by offering expert guidance and data-driven strategies that align environmental, social, and governance practices with long-term financial performance. For instance, in February 2024, according to Bloomberg L.P., a US-based financial information company, global ESG assets surpassed $30 trillion in 2022 and are on track to exceed $40 trillion by 2030. Therefore, the rising emphasis on ESG investing is fueling growth in the sustainable consulting market.

These platforms support sustainability consultancies by enabling more precise assessments, efficient reporting, and data-driven strategies that help clients meet regulatory and sustainability goals.
