Sustainability Signal Q3 2026: Follow the Risk

What moved in sustainability this quarter, and what it means if you run a small business or manage land.

This was the summer the planet's limits stopped being a report and started arriving as weather. Western Europe had its hottest June and July on record. About 71% of England was in drought by August. A war in the Gulf closed the Strait of Hormuz to many shippers from early March, and oil peaked at about $126 a barrel at the end of April.

Risk moved up: from farms and water sources to supply chains, then onto balance sheets, insurers and boards. And money began to come back down to reduce it. That, more than any new rule, is the story of the quarter.

We read each quarter through our Landscape Sustainability Framework. This quarter the framework changed too: we added risk as a fourth flow, beside capital, data and materials, because this summer risk behaved like one. Here is what that means if you run a small business or manage land.

The boundaries arrived as weather

In September the Planetary Health Check, from the Potsdam Institute for Climate Impact Research, found seven of the nine planetary boundaries crossed, and all seven at their highest recorded levels. Those boundaries rarely arrive as a science report. They arrive as a dry field, a hot workshop or a nutrient rule that stalls a planning application.

Water came first. With about 71% of England in drought, the Prime Minister chaired Cobra in mid-August, and on 14 August the government announced a £65m package under the headline "Farmers should not carry the risk of a changing climate alone": £50m for the Sustainable Farming Incentive and up to £15m for on-farm reservoirs.

Heat followed. The Climate Change Committee puts the chance of 40°C somewhere in the UK at about 4% a year, twenty times the rate of the 1960s. In June the Health and Safety Executive reminded employers that they already have to assess heat risk under existing health and safety law. There is no legal maximum working temperature, but there is a duty of care.

Nutrients showed how a boundary becomes a local rule. In Norfolk, nutrient pollution in the Broads and the River Wensum has been holding back new homes. Natural England's draft Environmental Delivery Plan, out for consultation until 27 October, would let developers pay a levy to Natural England (a draft £2,675 a home) instead of arranging their own mitigation, across up to 15,780 homes.

In practice: a small business names the one weather risk that would stop it (heat in the workplace, water, a supplier in a dry region) and who carries it. A land manager knows which boundaries show up on the holding: water, heat, nutrients.

The money followed the risk

Look at who paid for nature this year and a pattern appears. The government framed its drought money as sharing farmers' risk. Insurers, Zurich and Admiral among them, are backers of the Big Nature Impact Fund. Developers pay through Biodiversity Net Gain, where registered off-site gains now rank equally with on-site gains for smaller developments (since 6 August), and major infrastructure projects join the market from 2 November. In Norfolk, they may soon pay through a nutrient levy.

Lenders are pricing the same risk. In August, Moody's (as reported by Bloomberg) put nearly $2 trillion of rated debt across eight sectors at high or very high water-management risk.

The money also got stricter about proof. Programmes meeting the Core Carbon Principles now cover over 95% of voluntary carbon issuance (ICVCM, August 2026). For water, the World Resources Institute's revised accounting method ties a company's stewardship claim to the project still working and the company staying invested.

Public money, meanwhile, was rationed. The second window of the Sustainable Farming Incentive opened to all farmers on 22 September and closed the same afternoon once its budget was allocated. New agreements across both 2026 windows total £310m, capped at £100,000 a year each, and the next scheme is planned for 2027. Defra's forecast for 2025/26 has farm incomes falling for the majority of farm types. The public floor is thinner, so the private buyers matter more, and what they buy is risk reduction.

In practice: a land manager asks who carries the risk the land reduces (a water company, a developer, a food buyer, an insurer) and who is convening the catchment. A small business checks whether its customers, bank or insurer now ask about water or heat.

The law slowed; the questions didn't

Some rules settled this quarter. The Science Based Targets initiative published version 2 of its net-zero standard in June, moving companies from one-off targets to continuous delivery. The EU adopted a Voluntary Standard for smaller companies in July, and its revised reporting standards apply from financial year 2027. The UK's Seventh Carbon Budget became law in June.

Mandatory reporting slowed. The UK's sustainability reporting standards are voluntary for now; decisions on making them mandatory run through a consultation that closes on 30 November, and the FCA's rules for listed companies are still expected this autumn. In the EU, the Omnibus package cut its main reporting law to a fraction of its former scope.

The questions came anyway, and from closer to home. The British Business Bank's 2025 research found that 20% of small and 37% of medium businesses had been asked for carbon data by their customers. Surveys by CIPS, the procurement profession's body, reported in ISEP's Transform magazine, show responsibility for delivering ESG commitments moving into procurement teams. Lenders are pricing water. And in July ISEP warned that directors who ignore climate risk could breach their legal duties under section 172 of the Companies Act 2006.

One rule works in a small supplier's favour. From financial year 2027, an EU company reporting under the Corporate Sustainability Reporting Directive may not ask a supplier with up to 1,000 employees for more than the EU Voluntary Standard covers. The standard sets a ceiling on what a big customer can ask for.

In practice: a small business answers its customers rather than waiting for the law, and uses the EU Voluntary Standard as the shape of the answer. A land manager treats a buyer's supplier questionnaire as a request for evidence the farm may already hold.

Proof got cheaper

The carbon-accounting rulebook is settled for now. On 29 July the GHG Protocol and ISO announced that their corporate standards will fold into one consolidated standard, with a draft in 2027 and the final version in late 2028; the GHG Protocol has indicated that current guidance remains in force until then. A footprint built on today's rules will stay valid for years.

Proof is also becoming continuous. SBTi's new standard asks for annual progress reports. Water claims now depend on the project still working. The EU's Digital Product Passport registry went live on 20 July. And a new EU rating scheme will require data centres of 500 kW or more to disclose their energy and water use, including water use against local water stress, with first labels expected in 2027.

Measurement is within reach of a small team. Free satellite tools, Google DeepMind's AlphaEarth among them, now read crops and habitats at field scale. The step that matters for a farm or estate is to hold it in one place: a natural capital account, one record of the holding's soil, habitats, water and carbon, built from the schemes it already runs.

In practice: a land manager starts a natural capital account and settles the terms before that data enters anyone else's system. A small business builds an activity-based footprint once, on today's rules, and reuses it for every customer who asks.

The autumn: two COPs and a deadline

COP17, the UN biodiversity conference, opens in Yerevan, Armenia, on 19 October and runs to 30 October. It holds the first global review of progress against the 2030 targets for halting and reversing nature loss, and finance is the open fight. The ISSB's draft rules on nature-related disclosure are expected around the same time.

Closer to home, the Norfolk delivery plan consultation closes on 27 October and Biodiversity Net Gain reaches major infrastructure on 2 November. COP31, the UN climate conference, meets in Antalya in November. The UK reporting consultation closes on 30 November, and the shape of the 2027 farm scheme will follow. In Surrey, a proposed extension of the Surrey Hills National Landscape, about 129 km², now sits with the Secretary of State, with no timescale for a decision.

The practical takeaway is the one that runs through the whole quarter. The risk reaches the land, and the people who steward it, first. Follow it, and it leads to the buyers who will pay to reduce it. Resilience first. The markets are the upside.
