‘Pledge Fatigue’: From Net Zero Targets to Transition Credibility
In recent years, corporate sustainability has been defined by the boldness of its pledges. From ambitions to go carbon neutral by 2030, to reaching net zero by 2050, to adopting Science Based Targets as a marker of future intent, the message has been clear: Companies want to signal their commitment to climate action.
In the UK, the 2025 Carbon Budget and Growth Delivery Plan details policies aimed at getting the country to net zero by 2050, reflecting this same ambition at a national level.
Yet since these pledges have soared in popularity, so too has scepticism regarding them. Much of this stems from the failure of many organisations to translate bold words into tangible action.
The Issue
ClientEarth argues that the UK's net zero strategy merely pushes the issue into the future, avoiding the critical short-term actions recommended by the Climate Change Committee. Too often, targets are set and press releases issued, while the underlying business model remains unchanged.
This has led to a new phase in corporate sustainability, one where ambition without execution has become a liability, rather than a showcase of leadership.
The concept of "pledge fatigue" has taken hold. Stakeholders are tired of hearing about distant horizons when progress on the ground is invisible.
Investors are increasingly voting against weak transition plans. Regulators are demanding true substance over exaggerated claims and glossy marketing campaigns. Environmental NGOs are scrutinising loopholes with greater precision.
The question has shifted from "what are you aiming for?" to "what did you actually do last year?"
Credibility, in short, is no longer conferred by the end goal announced by a company. Instead, it is earned through the ongoing progress that they can demonstrate.
The Anatomy of a Credible Transition Plan
A credible transition plan is not a press release, nor is it a brief sustainability report designed for public relations. It is an operational, financial and governance blueprint for how a company will fundamentally change the way that it operates, produces, and remains profitable in a low-carbon economy.
A robust plan must demonstrate credibility across several interconnected dimensions, including:
1: Closer Milestones
A 2050 target is meaningless without interim goals (e.g., for 2030, 2035, 2040 and 2045). Showing a consistent improvement on emissions reductions is crucial to eventually meet the future goal, particularly when it is over two decades away. According to the Science Based Targets Initiative, a company aiming for net zero by 2050 should be able to demonstrate a 42% reduction in emissions by 2030. This provides a clear, measurable benchmark against which progress can be assessed.
Example: Tesco achieved a 65% reduction in emissions from its operations in 2024-25 (against a 2015 baseline).
2: Captial Allocation
Understanding where the money is going is vital; a credible transition plan should tie capital expenditure and operational budgets to decarbonisation activities.
This could include investment in research and development for low-carbon products, funding for supplier transition programmes, or even the early retirement of high-carbon assets. Ultimately, a target without a budget is a hope, not a plan.
Example: The Green Earth Group cites that British Airways is investing heavily in Sustainable Aviation Fuel, with a target of powering 10% of its flights by this method in 2030.
3. Governance and Accountability
Assigning a named executive-level owner to each workstream ensures that there is a specific individual answerable for delivery, rather than allowing responsibility to dissolve across teams.
Board oversight should be explicit and documented, while remuneration structures should be linked to the achievement of key transition milestones. Without clear accountability at these levels, there is no mechanism to ensure that ambition translates into action.
Example: Bloomberg stated that in 2021, Apple began adjusting bonuses for executives by up to 10% (as an increase or decrease) based upon progress towards ESG targets. However, just days ago Apple confirmed it has now removed this link between ESG targets and pay.
4. Scope 3 Coverage
Many corporate targets only cover Scope 1 and 2 emissions. Yet the Carbon Trust states that, for most sectors, Scope 3 emissions (those generated across the value chain) account for between 70-90% of the total carbon footprint.
Addressing this requires deep supplier engagement, influencing customer behaviour, and fundamental product redesigns.
Example: ISS Corporate Climate Analytics Data shows that, as of August 2025, only 29% of publicly traded companies in their global coverage reported Scope 3 emissions, rising to 48% for firms with a market cap exceeding $10 billion.
5. External Alignment
External dependencies must be acknowledged. Grid decarbonisation, policy support, and technological availability all sit partially outside of a company's direct control. However, a credible plan ensures advocacy alignment, meaning a company’s lobbying activities must match its stated climate ambitions.
Example: In 2025, Reuters reported that companies including ExxonMobil and Glencore were found to be lobbying for policies that directly conflict with their own climate pledges, with nearly 60% of net zero committed firms at risk of greenwashing due to such lobbying activities.
The Framework Shift
The organisations that once rewarded ambition are now rewarding transparency and delivery. CDP has fundamentally shifted its scoring methodology to assess transition plan quality rather than the mere existence of targets.
Some things that CDP now looks for include:
● Governance structures and board oversight
● Clearly articulated strategy aligned with climate science
●Risk management processes integrating climate considerations
● Detailed metrics and third-party verification of data
This evolution, from simple disclosure to the assessment of transition credibility, reflects a broader trend. Frameworks such as the Task Force on Climate-related Financial Disclosures, the Taskforce on Nature-related Financial Disclosures, the UK Transition Plan Taskforce, and the EU Corporate Sustainability Reporting Directive are all converging on the same fundamental point:
“Show us your plan, not just your promise.”
The nuance here matters. This is about making transition plans comparable, investable and accountable.
When investors can compare plans across sectors, they can then allocate capital with greater confidence.
When regulators can assess plans against clear standards, they can enforce with greater precision.
And when the public can scrutinise plans with consistent metrics, they can hold companies to account.
Data as the Foundation
A transition plan is only as credible as the data that it rests upon. If a company cannot accurately measure its current emissions, any future target lacks a solid foundation. The scale of this challenge is significant.
Sustainalytics claimed in 2023 that 60% of Scope 1 and 2 data, and more than 75% of Scope 3 data, is not reported by companies in their ESG scope.
Where companies do report, reliability remains a concern. Figures often rely on estimates and assumptions rather than direct measurement, leaving room for error.
Normative claims that a 2021 survey of executives across nine major industries revealed an estimated error rate of up to 40% in their emissions calculations.
These inaccuracies can lead to overestimated progress and overambitious goals, fuelling further scepticism.
The Cost of Inaction
The absence of a credible transition plan is not merely a reputational risk. It carries tangible and escalating consequences.
Investor action is becoming more assertive. Shareholders are voting against directors where transition plans are deemed inadequate. Some are divesting entirely.
Others are excluding companies from ESG funds, cutting off access to capital.
A 2025 Natixis survey of European investors representing over €8.5 trillion in assets found that 75% now assess a company's financial commitment to decarbonisation as a decisive factor in judging transition credibility.
Companies without funded, credible plans risk exclusion from the growing pool of transition-focused capital.
Regulatory risk is mounting. Fines, mandated corrective action, and in extreme cases, the loss of license to operate in certain markets are all real possibilities. In 2025, BBC News reported that the UK Advertising Standards Authority banned adverts for Nike, Superdry and Lacoste due to greenwashing.
Market exclusion is a growing threat. Major buyers are increasingly requiring suppliers to demonstrate credible transition plans as a condition of contract renewal. Companies without them risk being deselected from supply chains altogether. In the UK, this is already government policy. Since 2021, suppliers bidding for public contracts worth over £5 million must publish a Carbon Reduction Plan. Those that fail to do so, or cannot prove meaningful progress toward net zero, are excluded from consideration.
And finally, litigation is on the rise. A growing trend of greenwashing lawsuits targets companies with ambitious targets but weak delivery. The gap between promise and performance is becoming a legal liability.
In 2025, a Paris court ruled that TotalEnergies engaged in misleading commercial practices by claiming ambitions to achieve carbon neutrality while continuing to expand fossil fuel projects. Withers Law Firm reported that the company was ordered to remove the misleading statements from its website within one month or face fines of €10,000 per day.
The New Benchmark
The corporate sustainability leader of the future will not be defined by the earliest net zero pledge or the most ambitious goal.
They will be defined by three things: The quality of their transition plan, the integrity of their data, and the honesty of their progress reporting.
Companies that openly report both progress and setbacks will build more trust than those claiming perfection.
This is a generational shift in how corporate climate action is assessed. Targets remain important, but they are no longer sufficient.
The question is no longer what you promise for 2050, but what you delivered last year, what you will deliver next year, and how you can prove both.
