Environmental NGOs Challenge EU Carbon Removal Rules Over Bio-CCS and Biochar Integrity

A coalition of environmental NGOs has launched a formal challenge against the European Commission’s first certification methodologies for permanent carbon removals, arguing that rules covering Bio-CCS and biochar could weaken the environmental integrity of the EU’s emerging carbon removal market.

The request for internal review targets methodologies adopted under the EU Carbon Removals and Carbon Farming Regulation, known as the CRCF. The regulation is designed to create a voluntary EU-wide certification framework for carbon removals, carbon farming, and carbon storage in long-lasting products. It aims to help scale carbon dioxide removal while setting common quality standards that can reduce greenwashing and improve confidence in carbon removal claims.

The challenge focuses on two removal pathways. The first is biogenic emissions capture with carbon storage, often referred to as Bio-CCS, which involves capturing carbon dioxide from biomass-related sources and storing it permanently, usually underground. The second is biochar carbon removal, where biomass is thermally treated to produce a stable carbon-rich material that can be applied to soils or incorporated into products for long-term storage.

According to ESG News, the coalition includes Carbon Market Watch, WWF EU, Fern, Robin Wood, Protect the Forest, Association Workshop for All Beings, Save Estonia’s Forests, The Clean Air Committee, and 2Celsius. Legal and scientific support has also been provided by The Lifescape Project and the Partnership for Policy Integrity through the Forest Litigation Collaborative.

Why the Challenge Matters

At the centre of the dispute is whether the EU’s methodologies are robust enough to ensure that certified projects genuinely remove carbon dioxide from the atmosphere on a permanent basis. The NGOs argue that the rules do not adequately reflect current science and may fail to meet the core requirements of the CRCF, including accurate quantification, additionality, long-term storage, and sustainability.

The issue is significant because the CRCF is expected to become a reference point for buyers, investors, certification schemes, and project developers across Europe. The European Commission adopted its first set of methodologies for permanent carbon removals in February 2026, covering direct air capture with carbon storage, Bio-CCS, and biochar carbon removal. These methodologies are intended to allow certification schemes to apply for recognition and eventually issue EU-certified carbon removal units.

For companies and investors, the case highlights the growing importance of carbon removal quality. Carbon removals are increasingly viewed as necessary for balancing residual emissions that are difficult to eliminate, particularly in sectors such as cement, aviation, chemicals, and heavy industry. However, regulators and civil society groups continue to stress that removals should complement, not replace, deep emissions reductions.

Concerns Over Biomass and Forest Impacts

The NGOs’ concerns are especially focused on biomass use. Bio-CCS and biochar both depend on biological feedstocks, which can include wood, agricultural residues, forestry residues, and other organic materials. If biomass demand rises without strong safeguards, critics warn that carbon removal projects could increase pressure on forests, agricultural land, biodiversity, and local ecosystems.

A key concern is carbon accounting. Projects may appear to remove carbon from the atmosphere, but their real climate benefit depends on the full lifecycle impact. This includes emissions from harvesting, processing, transport, energy use, and storage, as well as potential indirect effects such as land-use change or reduced carbon storage in forests.

For forest-based biomass, the timing of emissions and removals is particularly important. Burning or processing biomass can release carbon quickly, while forest regrowth may take years or decades to reabsorb it. If certification rules assume biomass is carbon neutral without fully accounting for these timing effects, critics argue that removal credits could overstate climate benefits.

Biochar also raises questions about permanence and monitoring. While biochar can store carbon for long periods under certain conditions, its durability depends on feedstock type, production process, application method, soil conditions, and end use. Certification rules must therefore define how storage duration is measured, how reversals are monitored, and how uncertainty is addressed.

Implications for Carbon Markets and Corporate Claims

This is not only a technical debate. Carbon removal certification will affect climate finance, corporate net-zero claims, procurement strategies, and potentially future EU climate policy. The CRCF could become an important framework for determining which removals are considered credible in the European market.

If EU-certified units are eventually used in compliance systems or linked to future climate targets, their integrity will become even more important. Weak rules could allow credits with limited or uncertain climate value to enter the market, while strong rules could help direct investment toward projects that deliver durable and measurable removals.

For corporate buyers, the challenge underlines the need for careful due diligence. Carbon removal credits should not be treated as interchangeable commodities. Buyers need to assess the underlying method, feedstock source, lifecycle emissions, storage duration, monitoring arrangements, verification process, and governance structure behind each credit.

Companies using removal credits in climate strategies may also face reputational and legal risks if the credits are later found to be weak or overstated. This risk is becoming more relevant as EU rules on environmental claims and corporate sustainability reporting increase scrutiny of climate-related statements.

What It Means for Project Developers

For project developers, the challenge creates some uncertainty, but it also clarifies where market expectations are heading. Developers of Bio-CCS and biochar projects will likely face increasing pressure to provide transparent evidence on feedstock sustainability, lifecycle emissions, permanence, monitoring, and liability for reversal.

Projects that can demonstrate conservative accounting and strong sustainability safeguards may be better positioned as the market matures. This includes clear documentation on biomass origin, proof that feedstocks do not drive deforestation or ecosystem degradation, robust measurement and verification systems, and credible plans for long-term storage monitoring.

The challenge may also influence how certification schemes interpret and apply EU rules. Even if the Commission maintains the current methodologies, market participants may adopt stricter internal criteria to satisfy investors, corporate buyers, or civil society scrutiny.

A Test for the EU Carbon Removal Framework

For policymakers, the request for review places pressure on the European Commission to show that its certification approach can withstand scientific, legal, and public-interest scrutiny. The Commission may reject the request, revise parts of the methodologies, or provide further explanation of how the rules meet CRCF requirements.

The case also illustrates a broader tension in carbon removal policy. Europe needs credible ways to scale removals, but rapid market development without strong safeguards could damage confidence at an early stage. Biochar and Bio-CCS may both have roles in climate mitigation, but their climate value depends on rigorous accounting, transparency, and clear safeguards for forests, land, soils, and biodiversity.

The outcome of the NGO challenge could influence how Europe defines high-quality carbon removals and how much confidence investors place in EU-certified credits. It may also shape whether carbon removals are eventually integrated into wider compliance systems, including future reforms of the EU Emissions Trading System.

For businesses, the practical message is clear. Carbon removal credits can support climate strategies only when they are based on durable, additional, and accurately measured removals. As the EU carbon removal framework develops, due diligence will be central to managing climate impact, financial exposure, and reputational risk.
