The top 10 sustainability salary increases for the year ahead 

Sustainability remains an important business agenda for organisations, and employers are seeking out professionals who can align their operations with ever-growing legislation, frameworks and stakeholder expectations. 

We surveyed nearly 11,000 employers and employees across the UK, including 186 sustainability professionals, for our Hays UK Salary & Recruiting Trends 2025 guide. In addition to offering a comprehensive look into salaries across the sector, the guide uncovers some of sustainability’s key hiring challenges and industry trends. 

Here, though, we’re addressing three key questions: 

• What’s driving salary inflation across the sustainability sector?
• Which sustainability roles have seen the highest salary increases? 
• What are the hiring trends for the year ahead in sustainability? 

Salaries continue to grow amid skills shortages 

Green roles have seen strong salary growth, with 94% of sustainability employers increasing pay over the last 12 months – and as was the case the year prior, not a single employer we surveyed cited a decrease. 

Salaries across the sector have climbed by an average of 2.6% over the last year, edging above the UK average (2.4%). This upward trend looks likely to continue into 2025, with 84% of employers expecting sustainability salaries to increase in the coming year. 

Employers may feel compelled to keep salaries competitive amid ongoing skills shortages, which most organisations (88%) have experienced. Mid-level roles were the most difficult for employers to recruit for (57%), meaning hiring managers may be required to broaden their parameters when securing sustainability professionals. The sustainability sector is still a relatively new one, and employers cannot expect all the required experience to be readily available. In this vein, 75% say they’re likely to hire a professional who does not possess all the required skills for a role, with the intention of upskilling them. 

Significant pay rises for specialist sustainability roles  

While sustainability salaries have increased across the board, some fields have exceeded this average increase. Social impact and nature-based solutions have heightened in profile, and green professionals that can report on and fulfil these growing functions have seen an uplift in demand. 

Among the highest of these pay rises have been for ESG specialists (4.4%) and energy managers (3.6%), reflecting the need for professionals who can help organisations navigate the latest regulations and sustainability frameworks. 

Top 10 highest salary increases in sustainability: 

1. ESG specialist (experienced) 
2. ESG specialist (early career)  
3. Energy/carbon manager (early career) 
4. Environment manager (experienced) 
5. ESG specialist (senior leadership) 
6. Environmental consultant (early career) 
7. Environmental consultant (experienced) 
8. Energy/carbon manager (experienced) 
9. Sustainability consultant
10. Sustainability manager

Competitive pay just part of the talent attraction picture 

Our research shows that nearly half (48%) of sustainability employees plan on moving jobs in the coming year. Of those looking to make a move, a lack of future opportunities (42%) and dissatisfaction with salary and benefits (42%) are the main drivers. 

However, higher salaries and greater career prospects are not the only factors influencing candidate movement. It’s also clear that sustainability professionals desire greater flexibility from a job, with over half (51%) saying that they would not consider a role that doesn’t offer hybrid working. 

Beyond these considerations, sustainability staff are prioritising organisations with a clear purpose (85%), and unsurprisingly, those committed to sustainability (83%). Effectively communicating these credentials during recruitment and onboarding processes will be key when attracting in-demand green talent in 2025. 

And for professionals dissatisfied with their current pay, flexibility or long-term career prospects, now’s the time to tap into a buoyant sustainability hiring market. With four in five employers (80%) looking to take on green professionals in the next 12 months, you’ll want to keep an eye on our latest vacancies when considering your next move.
