The environmental consulting services market size was valued at US$ 41.40 billion in 2024 and is projected to reach US$ 63.94 billion by 2031; it is expected to register a CAGR of 6.5% during 2025-2031.

The environmental consulting services market is segmented into five major regions-North America, Europe, Asia Pacific (APAC), the Middle East & Africa (MEA), and South & Central America. North America dominated the environmental consulting services market in 2024. Europe is the second-largest contributor to the global environmental consulting services market, followed by Asia Pacific.

The environmental consulting services market in APAC is segmented into China, India, Japan, Australia, South Korea, and the Rest of APAC. Australia, China, Japan, India, South Korea, and the Rest of APAC are the major contributors to the environmental consulting services market in this region. The Asia Pacific region is emerging as one of the fastest-growing markets for environmental consulting services, fueled by a rapid surge in the demand for environmental consulting services, fueled by industrial expansion, urbanization, environmental degradation, and increasing government focus on sustainable development. As developing economies such as China, India, Indonesia, and Vietnam pursue aggressive infrastructure and energy growth, the environmental implications of these projects have necessitated robust consulting support to meet both domestic and international environmental standards. Furthermore, governments across the region are adopting stricter environmental regulations. For instance, China's Dual Carbon Goals aim to peak carbon emissions by 2030 and achieve carbon neutrality by 2060. India has implemented the National Action Plan on Climate Change (NAPCC), driving demand for climate advisory and clean energy transition services. Multinational corporations operating in the region are also under pressure to meet global ESG expectations, creating additional demand for environmental due diligence and compliance audits.

Key sectors such as construction, manufacturing, mining, and agriculture face significant environmental scrutiny, leading to heightened consulting activity in soil remediation, air and water quality assessments, and waste management planning. Additionally, the impact of climate change-including rising sea levels, floods, and typhoons-has highlighted the urgent need for disaster risk reduction and climate adaptation consulting. For instance, according to the World Meteorological Organization (WMO)'s State of the Climate in Asia 2024 report, the year 2024 ranked as either the hottest or second hottest year ever recorded. The report highlights that the region experienced intense and extended heat waves, contributing to significant climate stress. It also notes that the warming trend from 1991 to 2024 was nearly twice as strong as the trend observed between 1961 and 1990, underscoring the accelerating pace of climate change in the Asia region. This alarming rise in temperatures and extreme weather events has heightened demand for environmental consulting services. As governments, industries, and communities seek to adapt and respond to climate-related challenges, the environmental consulting services market is experiencing substantial growth. These services are now essential for developing climate resilience strategies, conducting environmental impact assessments, and supporting sustainability goals across sectors affected by rising climate volatility.

Based on the service type, the environmental consulting services market is segmented into monitoring and testing, investment assessment and auditing, permitting and compliance, project and information management, and others. The monitoring and testing segment held the largest environmental consulting services market share. Monitoring and testing services include the sampling and testing of air, soil, water, ecosystem, and noise for researching and identifying the effects of the same on the environment. This is an inevitable part of environmental impact assessment in certain industries. Government organizations also adopt these services for analyzing the load of pollutants in the ecosystem, as well as their effect on the same. Several municipalities hire environmental consultancies for monitoring and testing the water from lakes and rivers for chlorine and ammonium content, and turbidity levels prior to the activation line. The water is also monitored and tested during the water main/replacement projects. The other segment is expected to hold largest CAGR during the forecast period. The Water is one of the most essential raw materials in manufacturing facilities of the food & beverages, oil & gas, power generation, chemicals and petrochemicals, metal processing, semiconductors, and pharmaceutical industries. The water used for manufacturing can be highly contaminated and needs to be treated for the removal of toxic compounds before discharging it into water streams. Water management services offered by environmental consulting firms allow manufacturing facilities to set up water management systems that adhere to the emission laws applicable at the respective locality. Thus, with the growing concerns for preserving water bodies such as rivers, lakes, and streams, the demand for environmental consulting services for water management is also increasing.
