Carbonapp has built a portfolio of hybrid carbon contribution projects: natural sequestration and technological avoidance, here's why

The voluntary carbon market is undergoing a profound transformation. In an increasingly demanding context in terms of quality, integrity and traceability, Carbonapp has made the strategic choice of structuring a portfolio of voluntary carbon contribution projects that are at once diversified, rigorous and aligned with the underlying trends of the global market. The aim of this article is to explain our logic, our vision and why our model is based on the complementary nature of removal and avoidance projects, supported by data from the Ecosystem Marketplace 2025 report.

📉 A market in transition: quality, traceability and differentiation

According to Ecosystem Marketplace's 2025 Report, the voluntary carbon market is continuing to restructure: traded volumes have fallen by 25%, from 112 to 84 MtCO₂e, but the average price of credits has remained stable, masking however strong disparities according to project type: reforestation credits (ARR) reach an average of €18/tCO², agroforestry projects €12, and biochar projects trade above €85/tCO².

These levels confirm the market's move upmarket, driven by demanding financiers, mostly located in the northern hemisphere, who are prepared to pay a significant premium for projects with high integrity and traceability.

The most sought-after credits are those corresponding to high integrity criteria, validated by initiatives such as the ICVCM.

The market rewards projects with :

• with strong traceability and a controlled carbon credit generation forecast (volume and timeframe)

• with measurable co-benefits, transparently recorded

• with robust, up-to-date methodologies

• include sustainable impacts (sequestration) or credible avoidance (technology)

🧩 Our portfolio: voluntary complementarity between sequestration and avoidance

The Ecosystem Marketplace State of the Voluntary Carbon Market 2025 report reveals a real expectation of diversification, with 74% of respondents saying they would like to diversify their portfolios in 2025 to combine different types of project. The majority of respondents are looking to combine long-term sequestration with immediate-impact avoidance.

Carbonapp has built a mixed portfolio structured around these two major families of complementary projects:

🌲 Certified carbon sequestration projects

These projects aim to sustainably extract CO₂ from the atmosphere. They are certified by recognized standards and can be used as part of Net-Zero or science-based targets-type climate commitments :

• Label Bas-Carbone projects (France): post-fire reforestation, hedges, agroforestry

• Puro.earth and C-sink certified biochar projects: stable carbon sequestration (+100 years) in agricultural soils or in building materials such as low-carbon concrete

🎯 These projects offer a high level of integrity, with average prices ranging from €30 excl. tax/TeqCO2 for Low Carbon Label projects to over €200 excl. tax/TeqCO2 for biochar production projects issued on Puro.earth.

These “nature-based” projects, whether Low-Carbon Labelled (reforestation, hedges, agroforestry) or via the Puro.earth and Csink standards (biochar), offer major environmental and socio-economic co-benefits. They restore local biodiversity, protect soil and water resources, and strengthen the resilience of ecosystems in the face of climate change. In human terms, they support sustainable agricultural and forestry sectors, create local jobs, and contribute to the economic dynamism of rural areas. Biochar projects, in particular, improve soil fertility while storing carbon sustainably, offering a dual lever for climate and regenerative agriculture.

🔁 Emission-avoidance technology projects

These projects help avoid greenhouse gas emissions by promoting circularity, efficiency and reuse:

• Reconditioning of end-of-life electrical and electronic equipment (Riverse)

• Substitution of carbon-based materials by bio-based materials in construction (Riverse)

📊 These projects generate high volumes (>150,000 credits/year), with digital MRV and rigorous traceability.

These projects are chosen by Carbonapp for their massive contribution to the Sustainable Development Goals (SDGs). In fact, they generate numerous co-benefits over and above the reduction of emissions: they support the social and solidarity economy (SSE) by promoting the employment of people in integration or with disabilities, contribute to digital sobriety and inclusion, and reduce dependence on critical resources. The reconditioning of electronic equipment, for example, limits the consumption of rare and precious metals (lithium, cobalt, gold), helping to reduce pressure on global supply chains, curb strategic imports and, indirectly, reduce geopolitical tensions linked to the extraction of these raw materials.

🎯 A strategy designed for funders and regions

Our portfolio meets several of today's key market objectives:

• Offer volumes that are rapidly available “spot” and whose forecasts are controlled and rigorous to satisfy major multi-year needs. Here's an example with the Largo project, or the Isogreen project.

• Build long-term territorial projects, with low-carbon label afforestation or reforestation projects.

• Rigorous, responsive choice of standards, enabling us to address any size of project owner, and not just large-scale projects as is often the case with Verra VCS or Gold Standard, for example.

• Enable companies to contribute to global carbon neutrality by complementing their climate strategy with measurement, reduction and avoidance at source, without greenwashing.

• Reassure stakeholders of the real and measurable impact of the credits financed. The projects developed by Carbonapp are chosen for their integrity and their ability to drive the development of value chains. For example, relocating fruit production, or supporting reconditioning chains that are scaling up.

✅ Conclusion: a robust, credible portfolio aligned with the future of voluntary carbon

Carbonapp doesn't focus on just one type of project, but on the coherence between innovation, methodological rigor and delivery capacity. By reconciling certified sequestration and technological avoidance, we provide companies, local authorities and financial partners with concrete, measurable solutions in line with tomorrow's market requirements.
