UK corporations face significant pressure to make progress on decarbonisation. Simply setting targets is no longer enough. Regulators, investors, and customers are increasingly expecting corporations to have more robust carbon emission measurements, proof of delivery against decarbonisation targets, and a better understanding of how to decarbonise in a way that generates financial value.

Measure: Many UK companies are still early in the journey of measuring and disclosing their climate impact. Of the approximately 1,450 UK-headquartered companies that disclosed through CDP on climate (including approximately 91% of FTSE 100 companies), only around 70% of those disclosed actual Scope 1 and 2 emissions data. Only around 50% disclosed Scope 3 emissions data, of which approximately one-third use no primary data to calculate emissions. Though some of this is promising, success requires companies to understand and quantify their emissions across all scopes. CDP’s supply chain membership program can help companies collect primary Scope 3 data, analyse it, and engage with their suppliers to reduce their Scope 3 emissions.

Set Targets: Target-setting is on the rise, but is still limited. A growing number of UK companies are setting decarbonisation targets, with an average 52% per annum growth in target-setting from 2020 to 2022. The targets set are ambitious, with an average of approximately 6.5% per annum absolute reduction in Scope 1 and 2 emissions, which is above the 4.2% per annum reduction required for the Science-Based Targets Initiative’s 1.5°C pathway. However, only around 26% of UK companies disclosing through CDP have active Scope 1 and 2 targets. This falls further for Scope 3, to only around 15% of UK companies. As a result, targets only cover 31%–36% of the base year emissions reported by UK corporations. Target-setting is clearly still insufficient.

Deliver: Delivery of targets is challenging. Companies are not always underpinning their decarbonisation commitments with robust, quantified, and costed transition plans. This manifests in under-delivery: of the UK companies that disclosed through CDP and that have targets, 26% failed to meet their targets for 2021 and around 20%–30% are off-track against their pre-2030 targets. This challenge is seen across industries, particularly on Scope 3. Once all companies are accounted for—even those not disclosing—the scale of the challenge is far larger.

To successfully decarbonise, companies need to embed decarbonisation into their core business and link it to financial value.

To understand what it takes to decarbonise, we analysed the practices of companies that have effectively done so. We defined “effective decarbonisers” as the companies whose progress is aligned to the 1.5°C pathway (i.e., decarbonising their absolute Scope 1 and 2 emissions by 4.2% or more per annum).

Though there is no silver bullet to decarbonisation, we found that effective decarbonisers proactively embed decarbonisation into their core business and link it to financial value.

Specifically, effective decarbonisers: a) develop a transition plan with a wide range of initiatives, b) deploy incentives to bring people along, and c) incorporate decarbonisation into their core value proposition and link it to financial value.

Figure 2

However, above and beyond simply having a transition plan, the quality and robustness of the transition plan is of critical importance. In February 2023, CDP released a transition plan report which analyses the credibility of companies’ transition plans and found that less than 1% of the entire disclosure sample in 2022 reported sufficient detail to all 21 key indicators that align with a credible climate transition plan.

Companies that link decarbonisation to value expect to see financial benefit from their efforts.

Decarbonisation can create value from multiple sources: cost reduction, regulatory benefits, risk avoidance, access to financing, talent proposition, valuation, and revenue upside. CDP data shows that effective decarbonisers are likely to capture financial benefit from their efforts. They identify more financial opportunities from decarbonisation overall, identify higher value financial opportunities—and are particularly more likely to identify revenue-based growth opportunities from increased demand.

Recommendations for UK corporations

Measure: Disclose on Scopes 1, 2, and 3 and collect primary data to calculate Scope 3. Stakeholders are increasingly expecting companies to quantify and disclose carbon emissions.

Set Targets: Set a target for Scope 1 and 2 emissions (ideally an absolute target) and for Scope 3 as well (especially if Scope 3 represents a significant percentage of emissions). Underpin targets with quantified decarbonisation levers and use clear measurement to monitor (and project) progress against targets.

Deliver: Embed decarbonisation into your core business and link it to value.

• A. Develop a transition plan with a wide range of initiatives. For example, create a publicly available transition plan across Scopes 1, 2, and 3.
• B. Deploy incentives to bring people along. For example, deploy financial incentives for your executive and management teams and put an internal carbon price in place for several years.
• C. Embed decarbonisation to your core value proposition and link to financial value. For example, proactively search for green pricing premiums from existing products and/or monetize new low-carbon products.

By taking these actions to decarbonise, UK companies can drive better climate and financial outcomes.

About CDP

CDP is a global non-profit that runs the world’s only independent environmental disclosure system. As the founder of environmental reporting, we believe in transparency and the power of data to drive change. Partnering with leaders in enterprise, capital, policy and science, we surface the information needed to enable Earth-positive decisions. We helped more than 24,800 companies and 1,100 cities, states and regions disclose their environmental impacts in 2024. Financial institutions with more than a quarter of the world’s institutional assets use CDP data to help inform investment and lending decisions. Aligned with the ISSB’s climate standard, IFRS S2, as its foundational baseline, CDP integrates best-practice reporting standards and frameworks in one place. Our team is truly global, united by our shared desire to build a world where people, planet and profit are truly balanced. Visit CDP.net or follow us @CDP to find out more.
