Environmental Consulting Services Market Report 2025

The environmental consulting services market size has grown steadily in recent years. It will grow from $57.89 billion in 2024 to $60.01 billion in 2025 at a compound annual growth rate (CAGR) of 3.7%. The growth in the historic period can be attributed to low interest rates, strong economic growth in emerging markets, impact of e-waste, increased government regulation and a rise in shale oil and gas production.

The environmental consulting services market size is expected to see steady growth in the next few years. It will grow to $72.54 billion in 2029 at a compound annual growth rate (CAGR) of 4.9%. The growth in the forecast period can be attributed to the faster economic growth, increasing investments in smart cities, global collaboration for environmental protection, sustainable development and an increase in global construction activity will drive the growth. Major trends in the forecast period include adoption of innovative technologies and diverse services to increase market share, develop alternative solutions, offering AI/ML-based services, offering IoT related advisory solutions, offering drone services.

The forecast of 4.9% growth over the next five years reflects a modest reduction of 0.1% from the previous estimate for this market. This reduction is primarily due to the impact of tariffs between the US and other countries. Tariff barriers are expected to hamper U.S. sustainability advisors by increasing costs for GIS mapping tools and ecological risk assessment platforms imported from Canada and Australia, potentially delaying environmental impact studies while raising consulting fees. The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The environmental consulting services market is anticipated to experience growth in the future, driven by the increasing demand for water and waste management consulting services. Water and waste management consulting services involve providing professional advice and guidance to both companies and individuals regarding issues related to water and waste management. Collaboration between environmental consulting services and water and waste management consulting services is essential for effectively managing hazardous waste, minimizing its environmental impact, and offering guidance to businesses on adopting sustainable practices. This includes initiatives such as green building, proper waste management, utilization of renewable energy, and reduction of pollutants and emissions. For example, as per the Bureau of Labor Statistics, a US government agency, the waste management and remediation services subsector, encompassing waste treatment and disposal, employed around 372,000 people in May 2022. Therefore, the growing demand for water and waste management consulting services is a key driver of the environmental consulting services market's growth.

Sustainable development refers to the economic growth of a country or region with minimal depletion of natural resources. The United Nations Organization has established Sustainable Development Goals for all its members, outlining an agenda for responsible growth until 2030. These goals include ensuring equitable access to drinking water, enhancing water quality by reducing pollution and preventing hazardous waste dumping, constructing safe and resilient infrastructure, incorporating measures to address climate change in national policies, and promoting the sustainable use of marine and terrestrial resources. Investments aimed at achieving these targets are expected to generate demand for the services offered by environmental services companies.

Major players in the environmental consulting services market are actively pursuing strategic investments to establish their presence in the industry. Companies are making these investments in response to the expanding market and to address environmental concerns while complying with regulations. As an example, in April 2022, the UK-based professional services network, Deloitte, allocated a $1 billion investment in Deloitte Sustainability and Climate - a global practice dedicated to assisting clients in navigating towards a more sustainable future. This practice integrates various services, including advisory, assurance, audit, consulting, finance, and tax, providing clients with tools and insights essential for managing the transition to a sustainable future.

Environmental consulting firms are increasingly advocating for the adoption and implementation of Internet of Things (IoT) technologies to assist businesses and governments in monitoring and preserving the environment. For instance, environmental sensors are employed to measure particles causing pollution in the air and water, enabling the monitoring of air and water quality. These sensors can also identify radiation and hazardous chemicals in the environment. IoT technologies offer efficient solutions for waste collection and disposal as well. Smart waste collection systems have the capability to monitor waste levels in garbage bins, offering optimization for transport and operational analytics, ultimately contributing to savings in government assets and fuel consumption.

The sharp rise in U.S. tariffs and the ensuing trade tensions in spring 2025 are taking a toll on the professional services sector, especially within legal, consulting, architectural, and engineering fields. Increased duties on imported technology, software, office hardware, and digital infrastructure have pushed up operational costs for firms that rely on global systems and resources. Cross-border consulting engagements are experiencing delays and higher expenses due to elevated travel costs and limited access to international data and tools. Moreover, industries heavily impacted by tariffs such as manufacturing, construction, and logistics are reducing their reliance on outsourced services, dampening demand for professional support. In response, service providers are reassessing pricing models, strengthening ties with domestic vendors, and accelerating the adoption of AI and automation to maintain profitability and client satisfaction in an increasingly volatile environment.
