Sustainability Consulting Services Market Trends

Increased Focus on the Reduction of Carbon Footprint and Fulfilment of Net Zero Targets

The increasing focus on reducing carbon footprint has emerged as a primary driver of the sustainability consulting services market, with governments and businesses worldwide recognizing the urgent need to reduce greenhouse gas emissions. According to the GHG emissions report, global greenhouse gas emissions increased from 52.40 billion metric tons in 2018 to 53.79 billion metric tons in 2022, highlighting the critical need for expert guidance in emissions reduction strategies. This trend has been reinforced by significant initiatives such as the U.S. Department of Energy's July 2023 announcement of USD 23.4 billion funding for 16 projects across 14 states, aimed at providing technical assistance for carbon management technologies and increasing stakeholder participation.

The commitment to carbon reduction is further exemplified by major institutional investments and initiatives. In November 2023, CalPERS announced a USD 100 billion investment in climate solutions by 2030, coupled with a comprehensive strategy to reduce carbon intensity by 50% by 2030. This initiative includes corporate accountability measures through the divestment of investments lacking credible emission reduction plans. Additionally, in April 2023, global professional services company GHD expanded its sustainability agenda by committing to set net-zero greenhouse gas emissions targets through the Science Based Targets initiative (SBTi), demonstrating the growing trend of organizations seeking professional guidance to achieve their carbon reduction goals.

National Goals Across the Globe to Combat Climate Change

Nations worldwide are implementing ambitious climate action plans and policies, creating substantial demand for sustainability consulting services.

The Biden-Harris Administration has allocated USD 250 million for creating innovative plans to reduce climate pollution and establish clean energy businesses through the Climate Pollution Reduction Grants (CPRG) program, demonstrating the government's commitment to addressing climate challenges.

The global commitment to climate action is further evidenced by international collaborations and initiatives. During COP 27 in Sharm el-Sheikh, the Global Shield Against Climate Risks was launched as a joint effort between the G7 and V20 Group of 20 vulnerable nations. This initiative has garnered significant financial support, with France pledging 20 million euros for 2023, and a collective commitment of 210 million euros from Canada, Germany, the United States, France, Denmark, and Ireland. Additionally, the UK's participation in IDB Invest and the establishment of the UK Sustainable Infrastructure Programme (UKSIP) in March 2023 demonstrates the growing international cooperation in addressing climate challenges, with anticipated private funding exceeding £150 million for sustainable infrastructure projects.
