The Sustainability Consulting Market in 2025
Sustainability: A few years ago, it dominated business conversations, but the future hasn’t turned out to be as “green” as everyone expected.
Source has been gathering data on the global sustainability consulting market since 2022. Then, over half of businesses told us their goal was to be a leader in sustainability; now, just 31% say so, and clients are three times more likely to say they’re aiming to do the legal minimum. What’s more, one in eight businesses now say sustainability isn’t relevant to them at all.
There’s no doubt that this is a challenging market for sustainability consultants—but our latest data reveals that, while demand for sustainability consulting services might be harder to see, it’s not disappeared. In fact, a hefty 77% of clients say they intend to increase their investment in sustainability support in the next year alone.
“While we’re talking about a world that may be less likely to invest in sustainability, people are still prepared to do so,” explains Joel Bradbury, Senior Consultant. “It’s like going from Everest to Kilimanjaro—still a big, unmovable mountain of demand.”
