The COP17 biodiversity summit in Yerevan, Armenia, concluded on October 31, 2026, with governments adopting the Yerevan Pathway, a set of priorities to accelerate action on global nature targets through 2030. For corporates, the outcomes signal rising policy pressure on nature-harming subsidies, closer scrutiny of biodiversity credits and offsets, and a reaffirmed voluntary contribution benchmark for companies that use genetic data derived from nature. The negotiated decisions are addressed to governments, but the summit also launched a direct corporate track: an ISSB consultation on nature-related disclosure guidance that closes on February 19, 2027.

The urgency is clear. A UN global report released ahead of the summit found the world falling behind on 22 of the 23 targets in the Kunming-Montreal Global Biodiversity Framework (GBF), according to Carbon Brief. With four years left until 2030, the policy and market signals from Yerevan will shape how companies manage nature-related risk across their operations and supply chains.

Key Takeaways

COP17 Outcomes: Key Decisions from the Yerevan Biodiversity Conference

COP17 served as the midpoint review of the Kunming-Montreal Global Biodiversity Framework. Governments adopted nearly 50 decisions, completed the first global review of progress, and agreed the Yerevan Pathway. The outcome confirms that the 2030 nature targets are off track and that national policy action is expected to accelerate before COP18 in 2028.

COP17, the 17th Conference of the Parties to the UN Convention on Biological Diversity (CBD), concluded in Yerevan, Armenia, on October 31, 2026, with the adoption of nearly 50 decisions, according to The News Minute. The talks opened on October 19 and ran past their scheduled close, with a final plenary of roughly 12 hours, as Xinhua reported.

The summit marked the halfway point of the GBF, adopted in 2022 with 23 targets for 2030. These targets include conserving 30% of the world’s land and seas, restoring degraded ecosystems, and mobilizing resources for biodiversity, according to The News Minute.

The central outcome was the first global review of collective progress. Carbon Brief reports that the review expresses deep concern that the 2030 goal and its targets will not be met unless action accelerates rapidly. The review drew on a UN global report that found the world falling behind on 22 of 23 targets.

Unlike COP16 in Colombia, which lost quorum and had to resume in Rome months later, COP17 signed off on all major negotiation texts, according to Carbon Brief. Ecuador will host COP18 in 2028 after winning a secret vote against Panama, AFP reported.

Reactions were mixed. Guido Broekhoven of WWF International called the outcome a step forward despite weaknesses on harmful subsidies, while French Minister of Ecological Transition Monique Barbut said it was “not commensurate” with the crisis, according to AFP. Down To Earth described a meeting that leaned toward stocktaking over solutions for meeting the 2030 targets. Because the negotiated decisions are addressed to governments, most of their corporate impact will arrive through national policy and finance flows. The main direct channel for companies is the ISSB disclosure consultation launched alongside the talks.

What Is the Yerevan Pathway?

The Yerevan Pathway is the negotiated response to COP17’s global review, setting priorities for biodiversity action through 2030. It directs governments to reform harmful subsidies, align national budgets and economic decisions with conservation goals, scale up support to developing countries, and strengthen monitoring and reporting. Progress will be judged by measurable change.

The Yerevan Pathway is a set of priorities adopted at COP17 to accelerate implementation of the Kunming-Montreal Global Biodiversity Framework from 2026 to 2030. According to The News Minute, it is the negotiated response to the first global review of collective progress under the framework. Carbon Brief notes that the Pathway is formed by the sections of the global review that call on countries to scale up action, rather than a separate cover decision.

The Pathway sets out four priorities, according to The News Minute:

Progress under the Pathway will be assessed through changes in policies, the delivery of resources, and measurable improvements for nature and people, as The News Minute reported. The review text urges countries to accelerate implementation, including through increased ambition, while recognizing that developing countries need more support, according to Carbon Brief.

CBD Executive Secretary Astrid Schomaker framed the economic dimension directly: “We cannot protect nature while continuing to finance its destruction,” as quoted by The News Minute. She added that biodiversity must become part of everyday economic decisions.

The priority on aligning budgets and economic decisions matters most for corporates. When governments align fiscal policy, public procurement, and incentives with biodiversity goals, nature-related requirements may flow into the regulations, purchasing criteria, and disclosure expectations that companies face.

GBF Target 18: Harmful Subsidy Reform and Policy Risk for Nature-Intensive Sectors

Target 18 commits governments to identify harmful incentives by 2025 and to reduce them by at least USD 500 billion a year by 2030. COP17 encouraged faster implementation, although in softer language than early drafts. For companies that depend on fossil fuel or agricultural subsidies, reform represents a medium-term transition risk.

Under GBF Target 18, governments agreed to identify biodiversity-harming incentives by 2025 and then remove, phase out, or reform them, with an annual reduction of at least USD 500 billion by 2030. The scale of the task is large. Citing estimates from The B Team, Carbon Brief puts global spending on potentially harmful subsidies and incentives at up to USD 1.8 trillion a year, concentrated in sectors such as fossil fuels and agriculture.

Implementation lags the target. Carbon Brief analysis found that 84% of countries missed the 2025 identification deadline. Separately, a Conservation International report released at COP17 estimated that harmful subsidies generate between USD 11 trillion and USD 24.7 trillion in hidden environmental and social damage costs every year, as cited by Carbon Brief.

The COP17 global review encourages countries to accelerate implementation of Target 18 in accordance with national circumstances. Earlier drafts used the stronger verb “urge,” and the paragraph faced opposition from Saudi Arabia and Russia, with India proposing its removal late in the talks, according to Carbon Brief.

Business support for reform is growing despite the softer wording. More than 130 businesses and financial organizations signed an open letter before COP17 urging governments to reform nature-harming incentives, and Business for Nature chief executive Eva Zabey said the decision placed incentive reform at the center of the biodiversity agenda. A new “friends of target 18” initiative, convened by the International Institute for Sustainable Development (IISD) and co-chaired by Colombia and Finland, remains small for now. Armenia is the only other country officially involved, with France, Malawi, and Guinea indicating they will join, and full membership is due to be published in May 2027.

Fiscal pressure may drive reform more than environmental concern. Farooq Ullah, a senior policy advisor at the IISD, told Carbon Brief that governments may be acting on subsidies because they are out of money, and possibly not for environmental reasons at all. AFP identified fossil fuels, intensive agriculture, and overfishing as examples of activities supported by such incentives. Companies whose cost structures rely on subsidies in these areas should assess how exposed their operations and suppliers are to the withdrawal of these incentives.

How to Close the Biodiversity Finance Gap

The GBF targets at least USD 200 billion a year for biodiversity from all sources by 2030, yet developed countries missed their 2025 international finance goal. COP17 advanced four levers to close the gap: a broader contributor base, a post-2030 financial mechanism, new funding commitments that include private capital vehicles, and voluntary corporate contributions through the Cali Fund.

Under the GBF, countries committed to mobilize at least USD 200 billion a year from all sources by 2030, including at least USD 30 billion a year in international finance from developed to developing countries, according to The News Minute. The first global review found that developed countries missed their earlier goal of at least USD 20 billion a year by 2025. Delegates also pointed to a 27% decline in environmental funding for the 2026 to 2030 period, according to Carbon Brief.

The first lever is a broader contributor base. After a push led by developed countries to include emerging economies, the final decision invites countries outside the developed-country donor list to signal interest in joining through confidential consultations before COP18 and at every alternate COP thereafter, according to Carbon Brief. No country will be added without its explicit consent.

The second lever is a permanent financial mechanism for the period after 2030. COP17 established the mechanism under COP governance, but deferred the decision on whether it will be a new fund or rely on existing arrangements until COP18, according to Carbon Brief.

The third lever is new funding commitments. Nearly USD 2 billion in new biodiversity funding was announced at COP17, according to UN News. Selected commitments include USD 560 million in public funding under the latest Global Environment Facility replenishment and USD 500 million over five years from the Species Recovery Alliance, which brings together nine philanthropies, according to Campaign for Nature. The Value Nature Fund, which is designed to mobilize private capital for nature, was linked to USD 330 million: UN News describes this as money going to the fund, while Global Landscapes Forum describes it as a target set by the fund. The Asian Development Bank also launched a biodiversity bond and investment incubator. EU Environment Commissioner Jessika Roswall told Carbon Brief that the EU is looking at solutions beyond public money.

The fourth lever is voluntary corporate contributions through the Cali Fund. Created at COP16, the fund seeks payments from companies that profit from digital sequence information (DSI), the genetic sequence data drawn from biological resources. DSI underpins product development in sectors such as pharmaceuticals and agribusiness, from medicines and cosmetics to supplements and new crop varieties, according to Carbon Brief.

Contributions to the Cali Fund are voluntary. COP17 reaffirmed the indicative rates first set at COP16, equal to 0.1% of revenue or 1% of profit, and clarified that only contributions at these levels earn a Cali Fund certificate for the year, according to Carbon Brief. The decision directs half of the fund’s resources to Indigenous peoples and local communities, and allows exceptional payments once contributions reach USD 150 million.

The fund remains nearly empty. Pledges reached USD 10,565 by the close of COP17, with deposits below USD 9,000, and not one large company from DSI-reliant sectors has contributed. Because most operational details now move to negotiations before COP18, the main near-term issue for DSI users is reputational: the gap between commercial use of genetic data from nature and actual contributions is now a matter of public record.

Biodiversity Credits and Offsets: Market Momentum vs. Integrity Scrutiny

Biodiversity credits and offsets are recognized as a means of mobilizing finance under GBF Target 19, and the EU and China advanced market initiatives at COP17. At the same time, the final finance decision requests a study, subject to available funding, on whether credits and offsets deliver additionality. Companies should treat offset-led nature claims as an emerging integrity risk.

Target 19 of the GBF, which covers resource mobilization, accepts biodiversity offsets and credits as one route to raising finance, although their use remains contested. Falling public finance raised expectations that nature markets would gain ground at COP17.

On the momentum side, the EU launched an informal initiative called Friends of Credits for Nature and Biodiversity on October 27, co-hosted with France and Peru. According to Carbon Brief, the initiative aims to build governmental support and international cooperation on nature credits. It has been welcomed by Finland, Luxembourg, the Netherlands, Portugal, and Spain, as well as Australia, Botswana, Canada, Chile, Indonesia, Japan, and New Zealand. China also announced a nature markets pilot in Sichuan.

On the scrutiny side, Peru used the closing plenary to question offsets as a Target 19 finance instrument. The final resource mobilization decision requests the CBD Executive Secretary, subject to the availability of financial resources, to prepare or commission a study on whether biodiversity credits and offsets generate additionality, for consideration before COP18. Indigenous leaders at COP17 also rejected the use of charismatic species as credits to compensate for biodiversity loss.

CBD Executive Secretary Astrid Schomaker said before the summit that credits remain an important instrument if they are high-integrity, and that lessons from carbon credits should be applied, according to Carbon Brief. For companies, the parallel with carbon markets is instructive: credibility depends on verified, measured outcomes. Until the additionality study reports, nature claims built on measured reductions in a company’s own impacts are likely to carry less risk than claims that rely primarily on purchased credits or offsets.

ISSB Nature-Related Disclosures: The Corporate Reporting Track Launched at COP17

The most direct corporate development at COP17 came from outside the CBD negotiations. On October 22, 2026, the ISSB opened a consultation on a proposed Practice Statement for nature-related disclosures, drawing extensively on the TNFD framework. Comments close on February 19, 2027, and the ISSB confirms that IFRS S1 already requires material nature-related information.

The International Sustainability Standards Board (ISSB) launched its consultation on proposed nature-related disclosures during COP17, with a 120-day comment period that closes on February 19, 2027, according to the IFRS Foundation. The proposals are designed to help companies give investors material information on nature-related risks and opportunities, including how their dependencies and impacts on nature create those risks and opportunities.

The proposals do not create a new reporting obligation, but they clarify an existing one. The IFRS Foundation states that companies applying IFRS S1 must already disclose material sustainability-related risks and opportunities, including those related to nature. The proposed Practice Statement adds detail on how to provide this information. Companies would not need to comply with the Practice Statement to state compliance with ISSB Standards, although the ISSB is also asking for feedback on whether the content should instead be issued as a Standard.

The proposals build directly on the Taskforce on Nature-related Financial Disclosures (TNFD). The ISSB says it drew extensively on TNFD’s work, particularly on the relevance of location and on interactions with Indigenous Peoples, local communities, and affected stakeholders. TNFD Co-Chair David Craig said TNFD has completed its technical work on assessment and disclosure and is now focused on supporting the ISSB, according to the IFRS Foundation. The ISSB also designed the proposals so that companies applying the GRI Standards or the European Sustainability Reporting Standards (ESRS) can use them efficiently.

For companies, this is the COP17 development with the clearest reporting implications. While the CBD decisions bind governments, the ISSB track reaches companies through investor disclosure in jurisdictions that adopt ISSB Standards. Reporting teams should review the Exposure Draft, compare it with current climate and sustainability disclosures, and decide whether to submit comments before the deadline.

Nature-Related Risk Management: A Corporate Action Plan Before COP18

COP17 deferred several decisions to COP18 in 2028, while the ISSB consultation runs until February 2027. A practical response reviews the ISSB proposals, integrates nature into materiality assessments, maps supply chain exposure to subsidy reform, reviews DSI use, and builds value chain data that can support nature assessment alongside Scope 1, 2, and 3 carbon accounting.

The following framework translates the COP17 outcomes into corporate priorities. Each step responds to a specific decision described above.

This framework reflects the direction of COP17 decisions. Because the decisions are addressed to governments, the timing and form of resulting requirements will vary by jurisdiction.

What’s Next: Key Dates Through 2030

The next corporate decision points fall between early 2027 and 2030. The ISSB comment period closes on February 19, 2027, the friends of target 18 initiative plans to publish its membership in May 2027, COP18 meets in Quito in 2028, and the GBF targets fall due in 2030. Each date shapes the timing of corporate nature strategy.

COP18 will serve as the last checkpoint before the 2030 deadline, according to Down To Earth. Several items deferred at COP17 are expected to return there, including the operational design of the Cali Fund and the form of the post-2030 financial mechanism, according to Carbon Brief. The study on biodiversity credits and offsets, subject to available funding, is due to be considered by the CBD’s Subsidiary Body on Implementation at a meeting before COP18.

Conclusion: Turning COP17 Signals into Corporate Action

COP17 set direction for governments, and the ISSB consultation opened a direct disclosure track for companies. Governments have committed to reform harmful subsidies, align economic decisions with biodiversity goals, and examine the integrity of nature markets. Companies that build reliable value chain data now will be better positioned as nature-related reporting and policy requirements take shape before 2030.

As CBD Executive Secretary Astrid Schomaker noted, the real test is what governments change when they return home. For corporate leaders, the same applies: the value of COP17 depends on how quickly organizations turn its signals into measurement, strategy, and supplier engagement.

A credible nature assessment starts with knowing where value chain activity and emissions occur. ASUENE helps executive teams build that foundation through Scope 1, 2, and 3 measurement, supplier engagement with ASUENE SUPPLY CHAIN, and product-level assessment with ASUENE LCA. Contact ASUENE to begin Scope 3 measurement and prepare the value chain data your nature and climate disclosures will draw on.
