Environmental markets: Why early planning can unlock long-term value
For many farming businesses, environmental markets are no longer a future concept; they’re becoming an increasingly important part of long-term business planning.
Whether it’s biodiversity net gain (BNG), nutrient neutrality, carbon projects or habitat creation, opportunities to generate income from environmental assets continue to grow. While the commercial potential is attracting plenty of attention, it’s important not to overlook the practical considerations that come with these emerging markets.
The decisions made before an agreement is signed can have lasting implications for taxation, succession planning and the future structure of the business.

A new income stream, but not a simple one
Environmental projects can provide valuable opportunities to diversify income at a time when many farming businesses continue to face pressure from rising costs, changing agricultural policy and volatile commodity prices.
However, every opportunity is different.
Some projects generate a one-off capital receipt, while others provide recurring income over many years. Others involve creating an environmental asset that may eventually be sold or entering into long-term management agreements.
Each arrangement brings its own commercial, tax and succession considerations.
“Environmental markets represent an exciting opportunity for many farming businesses, but they’re not something to enter into lightly,” says Louis Smith, Adviser within Old Mill’s Rural team. “We’re increasingly having conversations with clients who want to understand not only what these agreements are worth today, but how they’ll fit into the long-term future of the business and the family.”
Looking beyond today's opportunity
When discussing environmental projects, it’s easy to focus on the immediate commercial return.
However, these decisions often have implications that extend far beyond the initial agreement.
As values for environmental credits become more established and the market matures, businesses will need to consider not only how income is generated, but also where that income should sit within the business.
Questions around ownership, business structure and long-term objectives become increasingly important.
For some families, environmental assets may support wider succession plans or provide opportunities for family members who are not actively involved in the farming business. For others, they may become an important part of future investment or retirement planning.
“One of the biggest mistakes we see is businesses viewing environmental agreements in isolation,” says Louis. “These decisions can have implications across the whole business, from tax and business structure through to succession planning. Looking at the bigger picture from the outset usually leads to much better long-term outcomes.”
Tax and succession should form part of the conversation
As environmental markets evolve, so too does the tax landscape surrounding them.
Questions around how income is taxed, how environmental assets are valued and which reliefs may be available are becoming increasingly important.
Inheritance Tax also remains firmly on the agenda for many farming families, making it essential to understand how environmental projects could affect wider estate and succession planning.
Recent HMRC consultations have highlighted that the tax treatment of environmental assets continues to evolve, reinforcing the importance of taking advice before agreements are entered into.
“The commercial opportunity is only one part of the equation,” Louis explains. “It’s equally important to understand how environmental assets fit within the ownership structure of the business, what they might mean for future succession plans and whether today’s decisions could have unintended consequences further down the line.”
Valuing an emerging asset
Environmental markets remain relatively new, and valuation approaches are still developing.
As more transactions take place, the market is likely to become more established, giving businesses greater confidence when assessing the value of environmental assets.
However, values may also change over time as agreements mature. Understanding how those values could evolve will become increasingly important, particularly where environmental assets form part of succession planning or future business transactions.
Taking a joined-up approach
Environmental opportunities shouldn’t be viewed as standalone projects.
The strongest outcomes are usually achieved when commercial, tax and succession planning are considered together.
Before entering into an agreement, businesses should ask themselves:
- Does this opportunity support our long-term business objectives?
- Is our current business structure still the right one?
- How will future income or capital receipts be treated?
- What impact could this have on succession planning?
- Have we considered the long-term implications as well as the immediate commercial return?
Taking the time to answer these questions early can help businesses maximise opportunities while avoiding unnecessary complications later.
Planning for the future
Environmental markets are creating exciting new opportunities for the rural sector, but they also introduce complexities that many businesses haven’t encountered before.
“This is a fast-moving area,” concludes Louis. “No two businesses are the same, which means there isn’t a one-size-fits-all solution. The businesses that will benefit most are those that take the time to understand both the commercial opportunity and the wider implications before making long-term commitments.”
As environmental markets continue to evolve, early planning will help businesses protect value, preserve flexibility and ensure these new opportunities support the long-term ambitions of both the business and the family.
