Hybrid Credits: Combining Carbon and Biodiversity Outcomes
Climate change and biodiversity loss are closely connected, yet environmental markets often address them separately. Hybrid credits offer an emerging approach that can connect carbon outcomes with measurable benefits for biodiversity and ecosystems within the same project or credit structure.
By integrating climate and nature outcomes, hybrid approaches can help direct finance toward projects that store or remove carbon while protecting, restoring or enhancing biodiversity. As these markets develop, understanding how the different outcomes are measured and verified will be essential for credible investment in nature.
Begreppet används fortfarande på olika sätt i marknaden, så formuleringen “emerging approach” är medveten. Det finns exempel på hybridmodeller där carbon och biodiversity kombineras, men ingen universell modell som alla “hybrid credits” följer.
What Are Hybrid Credits?
Hybrid credits are an emerging approach to nature finance that brings together multiple environmental outcomes, most commonly carbon and biodiversity, within the same project or financing structure.
A land restoration project, for example, may remove or store carbon while simultaneously improving habitat quality, supporting species recovery and strengthening ecosystem resilience. Hybrid approaches seek to recognize more than one of these environmental outcomes rather than valuing the project solely through its carbon impact.
There is currently no single universal definition or standard for a hybrid credit. Different projects and frameworks may structure combined environmental value in different ways. In some cases, multiple ecosystem benefits can be bundled into one product, while other approaches generate separate carbon and biodiversity credits from the same project area — often referred to as stacking.
This distinction matters because carbon and biodiversity are measured differently. Carbon outcomes can generally be quantified in tonnes of greenhouse gas emissions reduced or removed, while biodiversity requires indicators that reflect local species, habitats and ecosystem condition.
Credible hybrid approaches therefore need to clearly define which outcomes are being measured, how they are quantified and who can claim them. Appropriate accounting is particularly important when several environmental values originate from the same project, as poorly designed structures can create risks of double counting or overlapping claims.
The broader objective is to recognize the interconnected value of healthy ecosystems and potentially create stronger financial incentives for projects that deliver measurable benefits for both climate and nature.

How Do Hybrid Credits Work?
Hybrid credits work by connecting multiple environmental outcomes generated by the same project or landscape. Most commonly, this means combining climate benefits such as carbon sequestration or removal with measurable improvements in biodiversity.
A project might, for example, restore a degraded wetland or forest. The intervention could increase carbon storage while simultaneously improving habitat quality, supporting native species and strengthening ecosystem resilience. Instead of considering these outcomes entirely separately, a hybrid approach seeks to recognize more of the environmental value created by the project.
There are different ways to structure these outcomes. In a bundled approach, multiple ecosystem services can be represented together within a single product or credit. In a stacked approach, different outcomes — such as carbon and biodiversity — are measured separately and can potentially generate distinct credits from the same project area.
This means that measurement remains specific to each environmental outcome. Carbon can be quantified using greenhouse gas accounting, while biodiversity may require indicators relating to species, habitat condition, ecosystem integrity or ecological change.
The project also needs clear rules for baselines, additionality, monitoring and verification. This becomes particularly important when several credits or claims originate from the same intervention, as poorly designed stacking can increase risks around double counting and additionality.
A credible hybrid model therefore does not simply attach a biodiversity label to a carbon credit. It needs to demonstrate which outcomes have been created, how each has been measured and how the resulting environmental value is accounted for.
When designed carefully, hybrid approaches can help recognize that healthy ecosystems often deliver climate and biodiversity benefits simultaneously, while creating additional opportunities to finance integrated nature projects.
What Can Hybrid Credits Represent?
Hybrid credits can represent multiple environmental outcomes generated by the same project or landscape. The exact combination depends on the project, ecosystem and methodologies being used, but carbon and biodiversity are among the most relevant outcomes for integrated nature projects.
Carbon outcomes may include carbon sequestration, avoided greenhouse gas emissions or carbon removals resulting from activities such as forest restoration, peatland rewetting, agroforestry or improved land management.
Biodiversity outcomes can include improvements in habitat condition, species abundance, vegetation diversity, ecological connectivity or ecosystem integrity. Unlike carbon, these outcomes cannot usually be expressed through one universal metric and therefore require indicators adapted to the local ecosystem.
Projects may also generate wider ecosystem-service benefits, including improved water regulation, soil health, erosion control and greater resilience to climate impacts. Depending on the structure used, these benefits may be measured explicitly or treated as additional co-benefits rather than separate credits. OECD notes that ecosystem services such as carbon sequestration, biodiversity protection and water regulation can be packaged through different bundling or stacking approaches.
For example, restoring a degraded peatland could reduce greenhouse gas emissions while improving wetland habitat, hydrological function and conditions for native species. Similarly, forest restoration can increase carbon storage while creating more structurally diverse habitat and improving landscape connectivity.
However, the existence of several benefits does not automatically mean that each can generate a separate credit. Each claimed outcome needs appropriate measurement, additionality and accounting, particularly where multiple environmental credits originate from the same project area.
Hybrid approaches therefore have the potential to recognize a broader range of environmental value, while requiring clear boundaries around what is measured, what is credited and what is communicated as a co-benefit.
Hybrid Credits vs Carbon Credits and Biodiversity Credits
Carbon credits, biodiversity credits and hybrid credits can all help direct finance toward environmental projects, but they differ in what they measure and how environmental outcomes are represented.
Carbon credits primarily represent quantified greenhouse gas reductions or removals. They are typically expressed in tonnes of carbon dioxide equivalent (CO₂e), creating a relatively standardized unit that can be applied across different types of climate projects.
Biodiversity credits, by contrast, represent measured positive outcomes for biodiversity. These may relate to species, habitats or ecosystem condition and are inherently more location-specific. Unlike carbon, biodiversity cannot be reduced to one universally interchangeable metric.
Hybrid credits or hybrid approaches seek to recognize both types of environmental value within the same project or financing structure. A forest restoration project, for example, might generate measurable carbon sequestration while also improving habitat quality and ecological connectivity.
The way these outcomes are combined is important. Under a bundled model, multiple ecosystem services may be packaged together in a single unit. Under a stacked model, carbon, biodiversity or other ecosystem services may be quantified separately and potentially generate different credits from the same area.
This creates opportunities to recognize more of the value generated by nature restoration, but it also introduces additional accounting challenges. Projects need to demonstrate clearly which outcomes are being credited and ensure that the same environmental benefit is not claimed more than once. OECD highlights additionality, double counting and regulatory compliance among the key concerns associated with stacking environmental incentives.
The main difference is therefore one of scope: carbon credits focus on climate outcomes, biodiversity credits focus on biodiversity outcomes, while hybrid approaches attempt to connect multiple environmental outcomes within an integrated project model.
How Are Hybrid Credits Measured and Verified?
Measuring hybrid credits requires assessing each environmental outcome using methods appropriate to that outcome. Carbon and biodiversity represent different forms of environmental value and therefore cannot simply be combined into one universal measurement.
For the carbon component, projects may quantify greenhouse gas reductions or removals using established carbon accounting methodologies. Depending on the activity, this can involve measuring changes in biomass, soils, greenhouse gas emissions or other carbon pools and expressing the results in tonnes of carbon dioxide equivalent.
Biodiversity requires a different approach. Projects may monitor indicators such as species abundance, habitat condition, vegetation diversity, ecosystem integrity or ecological connectivity. These indicators need to reflect the local ecosystem and the specific biodiversity outcomes the project is designed to achieve.
Both components require an appropriate baseline against which change can be assessed. Projects also need to demonstrate additionality and establish monitoring systems capable of tracking whether the claimed outcomes continue to occur over time.
Verification becomes particularly important when carbon and biodiversity outcomes are credited separately. Each credit type should have clear evidence supporting the outcome it represents, while accounting systems need to prevent double counting or overlapping claims. Plan Vivo’s 2026 position on stacking, for example, requires carbon and biodiversity outcomes to demonstrate additionality independently and applies separate claims to the respective credits.
Depending on the standards or methodologies used, verification may involve independent third-party review, field audits, ecological surveys, remote sensing and transparent project reporting. The precise process will vary because there is currently no single universal verification framework covering all hybrid credit structures.
A credible hybrid approach therefore depends on more than demonstrating that a project benefits both climate and nature. It requires a transparent system showing what was measured, how the outcomes were calculated, how they were verified and which environmental claims are attached to each credit.
Benefits of Combining Carbon and Biodiversity Outcomes
Combining carbon and biodiversity outcomes can help projects recognize a broader range of environmental benefits from protecting, restoring and improving ecosystems. Rather than designing an intervention solely around carbon, an integrated approach considers how climate action can also contribute to healthier and more resilient ecosystems with biocredits.
One important benefit is improved project design. A project optimized only for carbon storage may not necessarily deliver strong biodiversity outcomes. For example, increasing tree cover can store carbon, but the ecological value will depend on factors such as species selection, habitat structure, location and existing ecosystem conditions. OECD similarly notes that poorly designed nature-based carbon projects, including inappropriate monocultures, can negatively affect biodiversity.
Integrated projects can instead identify areas where climate and biodiversity objectives reinforce each other. Restoring forests, peatlands, wetlands and other ecosystems can potentially increase carbon storage or reduce emissions while improving habitat quality, ecological connectivity and ecosystem resilience.
Recognizing multiple outcomes may also strengthen the financial case for restoration. Carbon finance can provide one revenue stream, while biodiversity and other nature-finance mechanisms may create additional opportunities to support projects that generate wider ecological value. OECD’s 2026 review highlights the importance of developing investable project pipelines and combining appropriate financing mechanisms to mobilize capital for biodiversity.
Another advantage is a more complete understanding of project performance. Monitoring both carbon and biodiversity can help identify potential trade-offs and ensure that progress toward one environmental objective does not unintentionally undermine another.
The greatest value of an integrated approach is therefore not simply the possibility of generating more than one credit. It is the opportunity to design projects around healthy, functioning ecosystems that deliver measurable benefits for both climate and nature.
How Businesses Can Use Hybrid Credits
Businesses can use hybrid credit approaches to support projects that generate measurable benefits for both climate and biodiversity. This can provide a way to direct environmental finance toward integrated nature projects rather than treating carbon and biodiversity as entirely separate objectives.
One potential use is financing restoration or conservation projects that align with a company’s broader climate and nature strategy. For example, a business could support forest, wetland or landscape restoration where both carbon outcomes and biodiversity improvements are measured and monitored.
Hybrid approaches may also help businesses identify projects that deliver environmental value beyond carbon alone. When evaluating nature-based carbon projects, companies can consider whether interventions also improve habitat quality, species diversity, ecosystem connectivity and resilience rather than focusing solely on tonnes of CO₂.
However, purchasing environmental credits should not replace action within a company’s own operations and value chain. Businesses should first understand their impacts and dependencies on climate and nature, work to avoid and reduce negative impacts, and use environmental finance as part of a broader strategy. This approach is consistent with emerging high-integrity guidance for corporate use of biodiversity credits.
Businesses also need to understand exactly what they are purchasing. Where carbon and biodiversity outcomes are bundled or stacked, buyers should examine the methodologies, baselines, additionality, verification processes and claims associated with each outcome.
Clear communication is particularly important. A company should be able to distinguish between a verified carbon outcome, a measured biodiversity outcome and an additional ecological co-benefit rather than presenting all environmental benefits as interchangeable.
Used responsibly, hybrid approaches can help businesses direct finance toward integrated projects that address climate change and biodiversity loss together, while creating greater visibility into the different environmental outcomes their investments support.
Challenges and Risks of Hybrid Credits
Hybrid credits can create opportunities to finance projects that deliver multiple environmental benefits, but combining carbon and biodiversity outcomes also introduces additional complexity and integrity risks.
One of the most important challenges is double counting. When carbon and biodiversity outcomes originate from the same project area, it must be clear which environmental benefit is represented by each credit and who is entitled to claim it. Without transparent accounting, overlapping outcomes could potentially be sold or claimed more than once.
Additionality can also become more difficult to demonstrate. If several revenue streams support the same intervention, projects need to establish whether each credited outcome represents a genuine improvement beyond what would have occurred without the relevant financing.
Measurement presents another challenge because carbon and biodiversity require fundamentally different approaches. Carbon outcomes can often be expressed in tonnes of CO₂e, while biodiversity depends on location-specific ecological indicators, baselines and monitoring methods. Combining them therefore requires robust but separate accounting for each environmental outcome.
Long-term outcomes must also be considered. Forests, wetlands and other ecosystems can be affected by climate change, land-use pressures, invasive species and other disturbances. Monitoring and appropriate management are necessary to understand whether claimed carbon and biodiversity benefits are maintained over time.
Hybrid structures can also create risks around environmental claims and greenwashing. Businesses need to communicate precisely what they have financed or purchased rather than implying that one environmental benefit automatically compensates for impacts in another area.
Finally, credible projects need appropriate social safeguards and governance. Land rights, local participation and fair benefit-sharing can be particularly important where projects involve communities or Indigenous Peoples.
Addressing these challenges requires transparent accounting, outcome-specific methodologies, credible verification and clear rules for environmental claims. Plan Vivo’s current approach to stacking carbon and biodiversity credits, for example, requires independent additionality for each credit type, separate methodologies and distinct claims to reduce double-claiming risks.
How Initiative 14/15 Supports Integrated Nature Projects
Developing projects that deliver both climate and biodiversity benefits requires an understanding of how different environmental outcomes interact within the same landscape. Initiative 14/15 supports organizations, landowners and project developers in identifying and developing integrated nature projects with measurable benefits for climate and biodiversity.
The process begins with understanding the ecological conditions and opportunities within a potential project area. Forests, wetlands, agricultural landscapes and other ecosystems can provide different opportunities for carbon sequestration, emissions reduction, habitat restoration and biodiversity improvement.
From there, project development can connect practical interventions with appropriate baselines, measurement approaches and monitoring systems. Carbon and biodiversity require different indicators, making it important to establish clearly how each environmental outcome will be assessed.
Initiative 14/15 also considers the wider ecosystem when developing nature projects. Factors such as habitat connectivity, water systems, soil condition, land use and long-term ecosystem resilience can influence both climate and biodiversity outcomes.
Where carbon, biodiversity or hybrid financing mechanisms are relevant, we can help explore how different environmental values could support the project while maintaining clear boundaries between measured outcomes, verified credits and additional co-benefits.
By combining ecological understanding with practical project development, Initiative 14/15 aims to help turn landscape opportunities into credible, measurable and financeable projects that create long-term value for both climate and nature.
Frequently Asked Questions About Hybrid Credits
Hybrid credits are an emerging approach to environmental finance that combines or connects multiple environmental outcomes, most commonly carbon and biodiversity, within the same project or financing structure. There is currently no single universally accepted definition or standard for a “hybrid credit”.
Hybrid approaches identify multiple environmental benefits generated by a project and establish how those outcomes will be measured and financed. Carbon and biodiversity outcomes may be bundled together or measured separately through a stacked approach.
Bundling combines multiple ecosystem services into a single unit or product. Stacking measures different ecosystem services from the same area separately, potentially allowing distinct credit types to be generated for outcomes such as carbon and biodiversity.
Carbon credits primarily represent quantified greenhouse gas reductions or removals, generally expressed in tonnes of CO₂e. Hybrid approaches consider additional environmental outcomes, such as measurable improvements in biodiversity, alongside climate benefits.
Biodiversity credits represent measured positive biodiversity outcomes. Hybrid approaches have a broader scope by connecting biodiversity with carbon or other ecosystem services generated within an integrated project.
Potentially, yes. Some frameworks allow stacking, where separate carbon and biodiversity credits can originate from the same project area. However, appropriate rules for additionality, attribution, accounting and claims are needed. Plan Vivo, for example, currently permits stacking subject to additional requirements.
Each environmental outcome should be measured using methods appropriate to that outcome. Carbon requires greenhouse gas accounting, while biodiversity may use indicators relating to species, habitats and ecosystem condition. Verification requirements depend on the standards and methodologies applied to the project.
No. There is currently no single global standard specifically governing all hybrid credits. Different standards and projects may use different approaches to bundling or stacking environmental outcomes, making it important to understand the methodology behind each project.
Important risks include double counting, unclear additionality, overlapping environmental claims, inconsistent measurement and greenwashing. High-integrity biodiversity-market principles specifically call for transparency when biodiversity credits are bundled or stacked with other ecosystem services.
Initiative 14/15 can help organizations, landowners and project developers identify and develop nature projects by connecting ecological assessment, carbon and biodiversity opportunities, project design and monitoring with appropriate environmental finance mechanisms.
