Most corporate boards in the UK have been having discussions on carbon for the past ten years. However, there is a paradigm shift in the conversation. The water supply is stretched, the soils are becoming poorer in Britain’s agricultural land, and businesses relying on such resources are beginning to feel the pinch.
This is where sbtn enters the picture.
The Science Based Targets Network has built a methodology that pushes companies beyond climate alone. It asks something harder: what is your business actually doing to nature, and what are you prepared to measure? For UK firms operating across food, fashion, finance, and infrastructure, this question is no longer optional. Investors are asking. Regulators are circling. And the early movers are already pulling ahead.
Here is what setting and validating nature-based targets actually involves, step by step.
Why Nature Targets Now Sit Alongside Carbon
Carbon targets were the gateway. They taught corporate finance teams how to measure something invisible and convert it into strategy. But nature is messier. You cannot reduce a freshwater catchment, a pollinator population, and a peat bog to a single tonne-equivalent metric.
That complexity is exactly why the sbtn framework matters. It splits nature into four realms: freshwater, land, ocean, and biodiversity. Each has its own measurement logic, its own pressure indicators, and its own action pathway.
For a British retailer sourcing cotton from water-stressed regions, or a London-listed bank financing palm oil expansion, the implications run deep. Your supply chain has a nature footprint whether you measure it or not.
Step One: Assess And Prioritise
The first stage of the sbtn process is materiality. You map your operations and value chain against environmental pressures, then identify where your impact is most significant.
This is rarely intuitive. A skincare brand might assume its packaging is the issue, only to discover that ingredient sourcing in semi-arid catchments dwarfs every other pressure on its books. A construction firm might find that aggregate extraction matters less than the embodied biodiversity loss in its timber supply.
You will need spatial data. Tools like the WWF Water Risk Filter, ENCORE, and the Global Forest Watch platform feed this stage. The output is a shortlist of issue-location-value-chain-stage combinations that genuinely warrant target setting.
Skip this step and everything that follows will be misdirected effort.
Step Two: Interpret And Prioritise Further
Once you have your materiality map, you sharpen it. Step two asks you to consider the local ecological context. A textile mill drawing water in Yorkshire faces a different reality from one drawing in Tamil Nadu. The same volume, different consequence.
Companies often resist this stage because it forces uncomfortable specificity. You can no longer say “we use water responsibly.” You have to say where, how much, and against what local threshold.
The reward for that specificity is credibility. When you eventually publish targets, they will withstand scrutiny in a way that generic pledges never could.
Step Three: Measure, Set, And Disclose Targets
Here is where most of the operational work happens. You establish a baseline, define a target boundary, and commit to a measurable outcome by a stated year.
The sbtn methodology currently has validated guidance for freshwater and land. Ocean and biodiversity targets are still progressing through technical development, though pilot work is underway. UK companies entering the process today typically begin with:
- Freshwater quantity and quality targets in priority basins
- No-conversion commitments for land in high-risk sourcing regions
- Land footprint reduction targets aligned with science-based thresholds
Each target needs a numerical baseline, a measurable indicator, and a clear timeline. Vague aspirations do not qualify.
Step Four: Act
Validation is not the finish line. It is the starting gun. After targets are formally accepted, you build the action portfolio that delivers them.
| Action Category | What It Looks Like In Practice |
| Avoid | Removing high-impact materials or suppliers from procurement |
| Reduce | Cutting water withdrawal in priority basins through process change |
| Restore | Funding catchment restoration where you operate |
| Transform | Reshaping sector-wide practices through coalition work |
The strongest corporate strategies combine all four. Avoidance and reduction sit closest to your operations. Restoration and transformation sit further out, often requiring partnership with NGOs, farmers, or local communities.
Step Five: Track And Report
Annual disclosure closes the loop. You publish progress against each target, refresh your data, and adjust where the science evolves. The Taskforce on Nature-related Financial Disclosures provides the reporting architecture most UK firms are already aligning with, and the two frameworks dovetail neatly.
Boards should expect this to become as routine as climate reporting within three to five years. The firms treating it as a tick-box exercise will be exposed when standardised assurance arrives.
Conclusion
A target is not science-based simply because you say so. The sbtn validation team reviews your submission against published technical guidance, checks methodology rigour, and either accepts the target, requests revisions, or rejects it.
This external check is the entire point. It transforms a corporate ambition into a credible commitment that auditors, investors, and procurement teams can rely on.
Nature is now a board-level concern in the UK, and the firms that learn this methodology early will negotiate the next decade from a position of strength. The ones that wait will find the rules written without them.
