The climate change consulting market size is expected to see strong growth in the next few years. It will grow to $12.6 billion in 2030 at a compound annual growth rate (CAGR) of 8%. The growth in the forecast period can be attributed to increasing demand for science-based climate strategies, rising investments in climate resilience planning, growing use of ai-driven climate analytics, expansion of carbon markets advisory services, increasing integration of climate risk into enterprise planning. Major trends in the forecast period include increasing demand for climate risk advisory services, rising adoption of emissions reporting and disclosure solutions, growing integration of data-driven climate modeling, expansion of corporate net-zero strategy development, enhanced focus on climate adaptation planning.

The increasing levels of greenhouse gas emissions are expected to drive the growth of the climate change consulting market going forward. Greenhouse gas emissions include gases such as carbon dioxide, methane, and nitrous oxide that are released into the atmosphere and trap heat, contributing to global warming and climate change. The rise in these emissions is largely driven by expanding industrial activities, higher fossil fuel consumption, rapid urbanization, and growing energy demand across sectors including transportation, power generation, and manufacturing. Climate change consulting assists organizations in measuring, managing, and reducing emissions through initiatives such as energy-efficiency improvements, carbon-reduction strategies, sustainability and regulatory reporting, and climate-risk mitigation planning. For example, in September 2024, according to the Emissions Database for Global Atmospheric Research (EDGAR), an Italy-based European Union scientific database, global greenhouse gas emissions reached 53 Gt CO₂eq in 2023 (excluding land use, land-use change, and forestry), representing the highest level on record and reflecting a 1.9% increase, or 994 Mt CO₂eq, compared with 2022. Consequently, the continued rise in greenhouse gas emissions is contributing to the expansion of the climate change consulting market.

Leading companies and key players in the climate change consulting market are increasingly focused on developing advanced solutions, such as global climate and sustainability centers of excellence, to strengthen their capabilities in predicting, assessing, and managing climate-related risks and sustainability strategies across industries. A global center of excellence for climate insight brings together multidisciplinary expertise in climate science, public policy, and corporate strategy to deliver actionable guidance on decarbonization pathways, regulatory compliance, and sustainable growth initiatives. For instance, in March 2023, Boston Consulting Group, a US-based management consulting firm, launched its global Center for Climate and Sustainability Policy and Regulation. The center provides in-depth analysis of emerging climate and sustainability regulations, develops sector-specific decarbonization and circularity strategies, and supports organizations in embedding low-carbon and nature-positive approaches into their operations and long-term business planning.
