How the IPBES Business & Biodiversity Report and TNFD Are Reshaping Corporate Accountability in 2026 

The Biodiversity Wake-Up Call

For years, biodiversity was the sustainability issue that finance and compliance teams quietly deferred to another department. Not anymore.

In February 2026, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) released its landmark Business & Biodiversity Assessment and it rewrote the terms of the conversation. Biodiversity loss is no longer framed as an environmental concern. It is now officially classified as a systemic risk to the global economy.

That language matters. “Systemic risk” is the vocabulary of central banks and financial regulators. It is the vocabulary of boards, not just CSR reports. And it is the vocabulary that, historically, precedes mandatory action.

The Scale of Exposure

Before diving into frameworks and timelines, it helps to understand why the urgency is real and why regulators are paying attention.

Put simply: if your business depends on stable supply chains, water, agriculture, fisheries, or raw materials, it depends on nature.  

From Voluntary to Mandatory: The Regulatory Arc

The progression here follows a familiar pattern in sustainability regulation. First come voluntary frameworks. Then reporting expectations harden. Then disclosure becomes mandatory. We have seen it with climate. Nature is following the same arc, only faster.

The Kunming-Montreal Global Biodiversity Framework, adopted in 2022, set the trajectory. Target 15 specifically calls on large companies to assess, disclose, and reduce their biodiversity impacts. The European Union is already embedding this into domestic regulation, with implications for any company operating in or exporting to the EU.

Meanwhile, 2026 is shaping up to be a critical platform year for the Science Based Targets Network (SBTN), which validated its first corporate nature targets in early 2025. The significance: for the first time, companies have a science-grounded methodology to set meaningful, measurable nature commitments and not just intentions.

The Taskforce on Nature-related Financial Disclosures (TNFD) provides the reporting architecture. With over 733 organizations already signed on across 56 countries, TNFD adoption is moving rapidly from early-adopter territory into mainstream expectation.

ASEAN: Caught Between Hotspot and Hub

The ASEAN region faces a particular tension in this moment. It is home to extraordinary biodiversity: the forests of Borneo, the marine ecosystems of the Coral Triangle, the agricultural landscapes of the Mekong Delta while also serving as one of the world’s most critical manufacturing and supply chain hubs.

That dual role creates both exposure and opportunity. On one hand, ASEAN-based companies supplying to European markets are increasingly subject to the EU’s emerging nature-related disclosure requirements. On the other, the transition to a nature-positive economy is projected to unlock significant new value across the region in sustainable agriculture, ecosystem services, and green finance.

Investor pressure is also intensifying. Institutional investors are increasingly seeking integrated climate-and-biodiversity reporting, treating nature-related risk as material to capital allocation decisions. For ASEAN companies seeking international capital, aligning with TNFD is rapidly becoming a market access question, not just a values question.

The Honest Reality: Implementation Is Hard

The frameworks are multiplying. The expectations are rising. The hard part? Making it operational.

The Nature Positive Initiative has identified over 600 different environmental metrics currently in use across corporate reporting. That fragmentation creates genuine confusion especially for sustainability teams trying to figure out where to start, what to measure, and how to ensure comparability.

A major consultation on metric harmonisation ran in early 2026, with the goal of building a more consistent, credible measurement framework. But in the interim, companies face a real risk of disclosure fatigue: producing reports that satisfy checklists without driving real change.

The more fundamental challenge is cultural. Biodiversity risk needs to move from sustainability departments into procurement, finance, and boardrooms. The gap between awareness and operational decision-making remains wide and closing it requires more than good intentions.

What Companies Should Do Now

The compliance clock is ticking but this is also an opportunity to get ahead of the curve. Here is a practical starting framework:

•       Start with a dependency audit. Assess your nature-related risks and dependencies using tools like ENCORE (Exploring Natural Capital Opportunities, Risks and Exposure), which maps how business sectors depend on and impact ecosystem services.

•       Map your value chain. Identify which parts of your value chain carry the highest biodiversity risk typically upstream in raw material sourcing. High-risk commodities include soy, palm oil, beef, timber, and certain minerals.

•       Align with emerging frameworks. Begin engaging with TNFD’s disclosure recommendations and explore SBTN’s corporate nature target methodology. Even voluntary adoption now builds credibility and prepares you for mandatory regimes ahead.

•       Bring nature into the boardroom. Biodiversity risk assessments need to inform procurement, investment, and strategic decisions not just sustainability reports.

•       Be transparent, not just optimistic. Disclose what you know and what you are working on but ensure it is backed by real data and measurable commitments. The era of narrativeonly sustainability reporting is ending.

A Defining Moment — If Companies Act Like It

Every major regulatory shift in sustainability has had a defining year, a moment when the direction became undeniable and the laggards became visible. For climate, it was the years following the Paris Agreement. For human rights due diligence, it was the wave of national legislation through 2021-2023.

2026 may be that year for nature.

The IPBES report has given policymakers and investors the scientific mandate. TNFD and SBTN have given companies the tools. The Kunming-Montreal Framework has given governments the political commitment. What remains is execution.

Nature is no longer a background condition for business. It is becoming a foreground compliance requirement. 

The companies that move now building measurement capability, integrating nature into strategy, and reporting with credibility will be far better positioned than those waiting for mandatory deadlines to force their hand.
