2025 was a year of reckoning for corporate sustainability. Regulatory momentum collided with political pushback, ESG faced intensified scrutiny, and businesses were forced to recalibrate their strategies in a more complex, often polarised landscape. What began as a decade of bold climate targets is now entering an era of delivery and disclosure, where stakeholder trust, market access, and long-term value are increasingly on the line. So what did 2025 really teach us about the state of sustainable business, and what’s coming next? Read on for the key shifts that shaped the past year and the predictions defining 2026.
What are the top sustainability trends for 2025?
From due diligence regulation to biodiversity disclosure and AI-driven ESG reporting, 2025 marked a major shift in how organisations manage risk, build resilience, and operationalise sustainability across functions. Here’s a closer look at the trends that defined the past year.
1. Biodiversity and nature-related risks take centre stage
In line with the Global Biodiversity Framework and the growing influence of the Taskforce on Nature-related Financial Disclosures (TNFD), businesses in 2025 began integrating nature risk into ESG reporting and enterprise strategy. Biodiversity loss is now seen as a material risk to supply chains, investment portfolios, and business continuity. Sectors such as agriculture, food, and construction led the way in adopting nature-positive strategies and location-specific impact assessments.
2. Climate adaptation gains ground alongside decarbonisation
While carbon reduction remains critical, 2025 underscored the growing need for businesses to prepare for physical climate risks, including extreme weather, water scarcity, and infrastructure vulnerability. The year saw an increase in climate scenario modelling, location-based risk assessments, and insurance-linked climate disclosures. Investors and insurers began prioritising companies with clear adaptation plans, beyond net-zero pledges.
3. Artificial intelligence becomes embedded in ESG operations
2025 marked the rise of AI-enabled ESG. Companies began integrating AI across sustainability functions, from automating supplier risk screening to enhancing energy optimisation in operations. In ESG reporting, AI was used to extract, standardise, and analyse sustainability data from diverse systems, reducing manual effort and improving auditability. Predictive analytics also helped identify supply chain vulnerabilities and forecast regulatory exposure.
4. Green claims under scrutiny like never before
Greenwashing came under greater scrutiny in 2025, as regulators around the world ramped up enforcement of misleading environmental claims. While the EU’s Green Claims Directive stalled mid-year, national authorities in the UK, Australia, and the US took more aggressive action. From legal investigations to increased consumer watchdog activity, companies were pushed to verify all public sustainability messaging. Marketing, legal, and ESG teams had to work in closer alignment, ensuring that claims were not only compelling, but also accurate and defensible.
5. Scope 3 decarbonisation takes centre stage
As regulators, investors, and customers demanded greater transparency, Scope 3 emissions (indirect emissions across the value chain) became the primary decarbonisation challenge in 2025. Pressure increased on companies to engage suppliers, align emissions methodologies, and set credible targets. Industries with complex supply chains, such as fashion, food, and electronics – were particularly under scrutiny.
6. Circular economy commitments gain regulatory teeth
Circularity moved from corporate aspiration to enforceable reality in 2025. Governments across the EU and Asia introduced new product standards, waste reduction targets, and Extended Producer Responsibility (EPR) schemes. Companies began embedding circular design principles into product development and taking responsibility for post-consumer waste. Packaging, electronics, and construction were key sectors of focus.

Sustainability predictions for 2026
As regulatory timelines tighten and stakeholder expectations evolve, 2026 is set to be a year of execution, where sustainability commitments are tested, and leadership is defined by action.
1. Regulation hits a tipping point
2026 will be dense with regulatory milestones, with the EU’s Corporate Sustainability Due Diligence Directive (CSDDD) entering enforcement for the largest companies, and the Corporate Sustainability Reporting Directive (CSRD) expanding disclosure requirements across Europe. Digital Product Passports will also begin rolling out in sectors such as textiles and electronics.
These shifts will not just affect large organisations. SMEs and suppliers, especially those within regulated value chains, will increasingly be required to collect and disclose ESG data. The result is a regulatory flywheel effect: as large companies comply, they pull the rest of the market with them.
2. AI moves from hype to strategic optimisation
After a rapid adoption phase in 2025, companies will enter the AI optimisation era in 2026. The focus will shift from experimentation to strategic deployment – using AI where it adds real value to sustainability efforts, such as automating ESG reporting, improving energy efficiency, or enhancing supply chain transparency.
Businesses will prioritise tools that simplify rather than complicate, with growing scrutiny around the environmental impact of large language models and data infrastructure. Responsible AI usage will become a key part of sustainable digital governance.
3. Sustainable IT becomes a strategic lever
Digital sustainability will move from the sidelines into core operations. Organisations will pay closer attention to the environmental impact of their IT systems – not just from an energy perspective, but through the full life cycle of hardware, software, and cloud usage.
This includes rightsizing infrastructure, deploying circular IT practices, and embedding ethical frameworks into digital product development. As more companies align net-zero targets with digital operations, sustainable IT will be treated as a measurable climate lever, not a niche concern.
4. The ESG skills gap becomes a barrier to progress
Despite growing pressure to meet sustainability targets, many organisations are constrained by a lack of internal expertise. In 2026, the skills gap will be more than an HR concern; it will be a business risk.
Companies will invest heavily in upskilling, creating internal training academies and sourcing practical, accredited learning options to reduce dependence on external consultants. Cross-functional ESG fluency, particularly in finance, procurement, and operations, will become a strategic asset.
5. Risk ownership moves beyond disclosure
Reporting climate and nature-related risks is no longer enough. In 2026, stakeholders will expect evidence of ownership, including scenario planning, board oversight, and integration into enterprise risk management frameworks.
This means identifying physical and transition risks across operations and supply chains, linking them to mitigation plans, and assigning internal accountability. Companies that fail to move from disclosure to action may face investor pressure, litigation, or reputational damage.
6. Regenerative thinking gains momentum
As sustainability matures, a new mindset is taking hold: regeneration. Rather than simply reducing harm, regenerative approaches aim to restore ecosystems, enhance biodiversity, and create net-positive impacts.
In 2026, expect to see more businesses embracing regenerative agriculture, circular product design, and buildings that generate more resources than they consume. This shift reflects a broader recognition that long-term resilience comes not just from risk management, but from actively contributing to environmental and social systems.
7. Water becomes the next material ESG issue
Water stress is rising on the global risk agenda, and 2026 will bring increased regulatory, investor, and consumer scrutiny of water use. High-impact sectors such as food, fashion, and manufacturing will be under pressure to measure, reduce, and disclose their water footprint, not only operationally, but across their value chains.
Water stewardship will move into core ESG metrics, with companies expected to demonstrate responsible sourcing, wastewater treatment, and resilience to water-related risks.
8. Digital Product Passports reshape value chains
Digital Product Passports (DPPs), set to become mandatory in several EU sectors by 2026, will transform how companies track, manage, and communicate information about their products.
These passports will contain detailed data on sourcing, materials, emissions, and end-of-life handling, supporting circular economy goals and enhancing consumer transparency. DPPs will drive operational changes in design, traceability, and supplier engagement, requiring new data systems and cross-departmental collaboration.
9. The language of ESG evolves
With ESG facing politicised pushback in some markets, businesses will adjust their messaging without retreating from sustainability goals. In 2026, more companies will frame their efforts in terms of resilience, value creation, and risk management, focusing on substance over slogans.
While the language may shift, the underlying imperatives around climate, equity, and transparency will continue to drive strategic change. Clear, credible communication will be critical to maintaining stakeholder trust.
10. Impact measurement becomes more robust and standardised
As expectations around transparency and accountability grow, companies will face pressure to move beyond vague targets and produce high-quality, decision-grade ESG data. In 2026, we’ll see greater alignment across global frameworks (ISSB, GRI, EFRAG, TNFD), helping to standardise impact metrics.
This will also support integrated reporting, linking financial performance with environmental and social outcomes. Businesses that can demonstrate measurable, credible progress will stand out in an increasingly data-driven sustainability landscape.
Conclusion
If there’s one thing to take away from business sustainability in 2025, it’s that sustainability is no longer a comms exercise or a siloed function; it’s a core business capability. The trends listed above reflect a broader shift where sustainability is now measured by ambition, but also execution. Stakeholders are asking tougher questions, ESG regulations are evolving rapidly, and technologies like AI are raising the bar for transparency and performance.
As we look to 2026, the challenges will only grow more complex, but so will the opportunities. The most future-ready organisations will be those that embed sustainability into decision-making at every level, build cross-functional fluency, and approach both risk and innovation with equal clarity.
