Gaps in businesses’ climate action plans slow progress on net-zero goals as global uncertainty remains

• Two-thirds of businesses have climate action plans, and only one in ten have made progress in developing one
• However, less than half have targets that meet scientific standards
• Inaction on climate risks could cost businesses up to 15% of annual revenue
  

Many of the world’s largest businesses do not have climate transition plans that are robust enough to support global efforts to cap rising temperatures. While some progress is being made more needs to be done to guard against the biggest environmental risks, according to the latest EY Global Climate Action Barometer.

The report examines the views of more than 850 companies across 50 countries and 13 sectors, that have been identified as climate leaders and assesses the extent to which they are taking action to achieve vital climate goals, and whether they are disclosing their actions in climate reporting. It looks at the steps they are taking and where they are falling short.

The findings reveal that, while two-thirds of businesses (64%) have ‘net-zero’ transition plans in place, and only one in ten (12%) have made strong progress in developing or disclosing plans, there are gaps that threaten to undermine progress.

“We’re delighted to be continuing our sponsorship of the EY Easter Running Festival and committing our long-term support to the Guernsey Athletics Club. It’s a privilege to support the Guernsey Athletics Club with such a fantastic, inclusive community event that has a positive impact on the health and wellbeing of so many people. I always look forward to this weekend and would encourage you all to get involved; whether you’re new to running, a seasoned athlete, or coming along to support a loved one taking part, it’s always such a great weekend to be a part of.”

Less than half (48%) of organisations have kept their targets in line with scientific guidance on how to mitigate against the worst effects of global warming.

Almost two-thirds (63%) of companies with net-zero targets rely on carbon credits, highlighting a dependence on offsetting their emissions rather than actively decarbonising. This use of carbon credits is especially high in financial services (78%) and transportation (69%) sectors, which are struggling to decarbonise.

The research also shows that one-third (34%) of businesses interviewed have restated their climate targets, citing factors such as reduced funding or regulatory uncertainty. Of these restatements, more than two-fifths (44%) were weakened, either by being less ambitious or because of delayed timelines.

According to the Barometer, most companies (68%) have assessed both the transitional risks and physical risks they face related to climate change, including those faced as they move toward decarbonisation and those that arise directly from climate-related events. However, less than a fifth (17%) report on the financial impact of these risks, leaving their exposure to climate change is not clear or quantifiable. Participants who register before midnight on Wednesday, 31 December, will receive an early bird ticket rates of 10% off the standard festival price.

Peter Miller, an Assurance Partner at EY in Guernsey, explains:

“The Barometer makes it clear that proactive climate action is no longer optional and is a strategic opportunity. For the Channel Islands, where financial services dominate, embedding climate risk management and sustainability into investment strategies is critical to maintaining global competitiveness. By turning ambition into action, we can position Guernsey as a trusted hub for climate-conscious capital and play a meaningful role in the global transition to net zero.

Online registration for all entries will close strictly on Sunday, 29 March at 23:59. Visit the Guernsey Athletics Club’s website to enter “Guernsey has been a leader in developing and implementing sustainable finance and climate change policies, products and services and is supported by a robust regulatory framework. This was evident through the GFSC’s Guernsey Green Fund, the world’s first green fund. It’s crucial that businesses utilise these frameworks to tackle climate risks and ensure all their efforts are disclosed and reported effectively to build trust with their clients and investors.”

The vast majority of the leading businesses that took part in the research (92%) state they have fully analysed the likely impact of physical risks on their operations. However, only two-fifths (44%) report having measures in place that will help them adapt to manage these risks.

The research also points to a lack of effective governance across many organisations, potentially undermining their efforts to take action on climate change. For example, just 8% of companies have board oversight over capital allocation, 21% over target setting, and only 41% over progress monitoring.

Separate EY analysis, alongside the Barometer findings, highlights the cost of inaction for businesses. It shows that where organisations fail to address the risks of climate change, they could lose out on up to 15% of annual revenue.

Peter concludes: “The Barometer sets out a series of recommendations to help businesses plan and execute climate transition. Businesses are advised to embed climate goals into strategy, implement clear transition plans, risk assessments and governance processes; and explore the opportunities offered by AI.

“For any business to remain resilient and ensure continuity in the face of climate change, long-term planning is essential. This means implementing actionable transition plans that demonstrate proactive risk management and adapting strategies as we move toward a low-carbon economy.”

About the research 

The EY Global Climate Action Barometer provides an annual analysis of organizations’ climate-related risk disclosures, with the aim of tracking their progress against climate related goals. This assessment provides not only companies, but also external stakeholders of all types (such as national regulators, financial institutions and investors), with an understanding of the current state of global climate reporting and transition planning.

The first edition of the Barometer (then named the EY Global Climate Risk Barometer) was issued in December 2018. Since then, the Barometer has analyzed the extent to which the disclosures of approximately 1,400 global companies are in line with the 11 pillars of the Task Force on Climate-related Financial Disclosures, and their preparedness for, and level of adoption of, IFRS S2. It also measures the extent to which climate-related risk and opportunities are reflected in companies’ financial statements. The last analysis of this nature was conducted in 2024.

This year’s Barometer is a more targeted study, focusing on 857 companies across 50 countries, operating in 13 sectors. EY teams analyzed the reporting of these companies to assess the level of action being taken in key areas including decarbonization, risk mitigation, target setting and use of carbon credits. Compared with previous Barometers, this study offers a more in-depth analysis of companies’ progress with climate action, transition planning and adaption to climate risk. It also highlights where good progress is being made and where greater improvement is needed. Companies selected for inclusion were drawn from the population of companies analyzed for the 2024 EY Global Climate Action Barometer (CAB24). They were identified as showing leadership on climate ambition, disclosure quality and climate risk management.

Companies that had already disclosed or were preparing to disclose a climate transition plan in CAB24 were prioritized, reflecting a strategic commitment to decarbonization. Also included were companies that had started their climate risk journey — i.e., they had undertaken a qualitative risk assessment as a basic minimum. The selected companies demonstrated strong climate risk governance, including quantitative scenario analysis and a superior climate financial impact rating.

The findings of this study are primarily based on companies’ public disclosures and assume that all of their actions/ initiatives are disclosed in their corporate reports/ CDP reporting for either 2023 or 2024. Analysis of the disclosures was undertaken between April and July 2025. In addition, eight in-depth qualitative interviews were conducted with EY subject matter professionals. These interviews explored the trends in the results and their implications for individual sectors.
