Target 15 of the Kunming-Montreal Global Biodiversity Framework is the provision that most directly affects corporate behavior in the near term. It requires large and transnational companies and financial institutions to regularly monitor, assess, and transparently disclose their risks, dependencies, and impacts on biodiversity — and then to progressively reduce negative impacts. For sustainability officers navigating disclosure frameworks, understanding what Target 15 actually obligates — and what verified biodiversity credits can and cannot do to support compliance — is now an operational priority.
What Target 15 Actually Says
The full text of GBF Target 15 states that by 2030, Parties shall take legal, administrative, or policy measures to encourage and enable businesses — especially large and transnational companies and financial institutions — to:
- Regularly monitor, assess, and disclose their risks, dependencies, and impacts on biodiversity across their operations, supply chains, and portfolios
- Provide information needed to consumers to promote sustainable consumption patterns
- Report on compliance with access and benefit-sharing regulations and measures
- Progressively reduce their negative impacts on biodiversity and increase positive impacts
Several features of this text deserve attention. First, Target 15 addresses "Parties" — meaning national governments — not companies directly. The obligation is on governments to create the legal and policy frameworks that require corporate action. How rapidly and rigorously individual governments move to translate GBF Target 15 into binding domestic regulation varies significantly. Second, the language is "large and transnational" companies — smaller domestic companies are not within the explicit scope of Target 15, though they may fall within domestic biodiversity legislation that is separately motivated.
Third, and most importantly for credit buyers: the primary obligation under Target 15 is monitoring and disclosure, not offsetting. The framework calls for companies to "progressively reduce negative impacts" — but it does not specify that biodiversity credits are the mechanism. Credits are one tool for demonstrating that negative impacts have been addressed; they are not the only tool, and they are not a substitute for reducing the underlying impact where operationally feasible.
From Target to Disclosure: The TNFD Bridge
TNFD explicitly positions its recommendations as the corporate implementation pathway for GBF Target 15. The TNFD LEAP framework (Locate, Evaluate, Assess, Prepare) provides the structured process by which companies identify their biodiversity dependencies and impacts — the monitoring and assessment step that Target 15 calls for — and then disclose against standardized metrics.
TNFD-aligned reporting does not require biodiversity credits. But for companies that, having completed a LEAP assessment, identify material residual biodiversity impacts that cannot be fully avoided or reduced through operational changes, purchasing verified credits is the mechanism by which they can demonstrate a positive contribution toward net outcome. TNFD Metrics & Targets disclosure should then reference those credit purchases with sufficient specificity — methodology, geography, species evidence, retirement record — to be auditable.
Target 15 and Corporate Credit Procurement: A Realistic Frame
It is worth being direct about what biodiversity credits can credibly claim to deliver in the context of GBF Target 15 compliance. Credits are most defensible when:
- They represent measurable biodiversity uplift at a geographically specific site, verified by independent third-party ecological assessment
- The credit geography bears some reasonable relationship to the buyer's impact geography — a credit in an adjacent watershed to an operational footprint is more defensible than an offshore credit used to offset a domestic impact
- The underlying site has a permanence commitment that is monitored over time, not a one-time snapshot
- The credit is formally retired against a specific disclosed obligation, not just purchased and held
Credits are weakest when used to claim that material operational biodiversity impacts have been "fully offset." The no-net-loss framing is difficult to defend with scientific rigor for complex ecosystem impacts — the ecological community affected by an operational footprint and the one supported by a credit site are not interchangeable. A more defensible framing is: "We have an unresolved biodiversity impact at Site X; we have purchased and retired verified credits at Site Y representing a measurable species-level biodiversity improvement, and we are reporting both the impact and the positive contribution transparently."
The highest-integrity approach to GBF Target 15 compliance pairs honest impact disclosure with verified positive contributions — not a claim that the credits make the impact disappear.
The Role of Additionality and Baseline Counterfactual
Two methodological concepts are central to evaluating whether a biodiversity credit genuinely contributes to Target 15 progress: additionality and baseline counterfactual.
Additionality asks whether the biodiversity improvement would have happened anyway without the credit financing. A restoration project on land that a conservation-minded landowner would have protected without payment is arguably non-additional — the credit sale does not change the ecological outcome. Strong additionality requires evidence that the credit payment is causally necessary for the restoration activity to occur and be maintained.
The baseline counterfactual asks: compared to what scenario is improvement being claimed? A site that went from degraded pasture to restored riparian forest shows genuine uplift against its pre-restoration baseline. A site that was already mature forest and receives a "protection credit" for not being logged is a weaker additionality claim — the baseline counterfactual (logging) may be speculative.
Our BHI methodology accounts for both: we require documentation of pre-restoration baseline conditions from enrolled sites, and we require land managers to demonstrate the restoration activity would not occur under existing conservation commitments or legal obligations. These are demanding standards relative to some voluntary market programs, but they are necessary to produce credits that credibly support Target 15 disclosures rather than merely appearing to do so.
The 2030 Timeline and What It Means for Procurement Now
GBF Target 15 has a 2030 deadline for monitoring and disclosure systems to be operational. Given that large companies typically require 2–3 years to build well-functioning ESG data collection infrastructure, and that biodiversity credit procurement typically requires due diligence timelines of several months for novel credit types, companies that wait until 2028 to build their biodiversity disclosure program will find themselves compressed against an already-tightening regulatory timeline.
Early engagement with the credit market also positions buyers to participate in establishing methodology norms. The standards that will define acceptable evidence for Target 15 disclosures are still being formed — and buyers who have experience with verified, species-level credit documentation are better positioned to advocate for rigorous standards than buyers who have only purchased area-proxy credits and have a financial interest in defending weaker methodologies.
