Harnessing Carbon Removal Opportunities in Wastewater Treatment
The report examines how wastewater treatment plants can be transformed into carbon removal hubs by managing alkalinity and repurposing biosolids. It identifies two primary intervention categories: alkalinity management (including Wastewater Alkalinity Enhancement and Ocean Alkalinity Enhancement) and biosolids management (including biomass burial, biochar, supercritical water oxidation, and incineration with CCS). The document highlights synergies such as the safe destruction of PFAS and the use of existing pumping infrastructure to reduce capital and energy costs. Globally, the biogenic carbon in municipal wastewater represents a theoretical removal potential of 120–460 MtCO2 per year, though current treatment rates limit this to 70–260 MtCO2. Key barriers to scale include feedstock supply chain development, quantification challenges for carbon credits, and ecological risks.

Not Just Voluntary Credits: Three CDR Demand Trends to Support and Scale
The document argues that relying solely on voluntary corporate credits is insufficient for scaling CDR and proposes three diversified demand pathways: credit purchasing through government procurement and compliance markets, demand for differentiated low-carbon products enabled by carbon accounting and 'Buy Clean' policies, and 'flipping the script' by funding services where CDR is a co-product, such as wildfire prevention or waste management.

Leaning on Uncertainty
Austria aims for climate neutrality by 2040, relying on industrial carbon removals (up to 6.3 Mt CO2eq) and land sinks, yet lacks a legally binding national climate law. While the 2024 Carbon Management Strategy (CMS) provides a transparent roadmap, significant delivery risks exist regarding the technical feasibility and timing of CO2 transport and storage infrastructure. Furthermore, there is high uncertainty regarding the long-term performance of the LULUCF sector and a lack of safeguards to prevent BECCS deployment from degrading the natural land sink.

Leaning on Uncertainty
Finland relies on Bioenergy with Carbon Capture and Storage (BECCS), biochar, and land sinks to reach its 2035 carbon neutrality target, but faces significant delivery risks. The government has disregarded scientific advice from the Finnish Climate Change Panel to moderate logging levels to restore the declining land sink, which currently shows rising net emissions. While the government is pursuing BECCS, it lacks domestic geological storage and must rely on international transport and storage, which are constrained by limited capacity in Northern Europe. Furthermore, current financial allocations for BECCS are significantly lower than the estimated needs to achieve projected removal volumes.

Leaning on Uncertainty
The document argues that Norway's climate strategy relies on uncertain land-sink removals and international offsets rather than feasible domestic emission reductions. It identifies systemic deficiencies in impact assessments, a lack of separate LULUCF targets beyond 2030, and a conflict of interest where geological storage sites are evaluated based on their potential to interfere with future petroleum activity. While some industrial removal projections are cautious, the report notes a lack of binding limits on international credits and significant gaps in biomass sustainability evaluations.

Leaning on Uncertainty
The report finds that European governments are increasingly integrating carbon dioxide removals (CDR) into their climate strategies, often as a substitute for deep emission reductions. Analysis of the European Commission and six countries reveals a pattern of 'overreliance,' characterized by fragmented planning, a lack of feasibility assessments for engineered removals, and land-sink projections that ignore climate risks or contradict existing forestry policies. The report warns that betting on uncertain future technologies and unstable land sinks risks delaying essential decarbonization and undermining climate targets.

Reject the CRCF Delegated Act for permanent removals - it remains unsatisfactory
Carbon Market Watch and Fern call for the rejection of the CRCF Delegated Act for permanent removals, citing four primary flaws in BioCCS and biochar methodologies: insufficient consideration of biomass extraction's climate effects on land, lack of minimum capture rates for BioCCS, the use of zero baselines that ignore regulatory progress, and the failure to evaluate biomass feedstocks by carbon payback times. The authors warn that these deficiencies risk certifying projects that add emissions rather than removing them, potentially compromising the integrity of the EU ETS if these credits are integrated. They further criticize the vague rules and the potential for a 'race to the bottom' among certification bodies and auditors paid by operators.

Exploring Biomass Carbon Removal and Storage (BiCRS) Scenarios for California
The report analyzes the potential for California to meet its 2045 CDR target of 75 MMT CO2e by diversifying its portfolio with Biomass Carbon Removal and Storage (BiCRS) systems. Using seven scenarios based on cost and social acceptance, the study finds that BiCRS can remove between 13 and 75 MMT CO2e annually. Scenarios utilizing high biomass availability estimates show that BiCRS alone could meet the state's target, potentially reducing costs and increasing bioenergy and job production by up to 10 times compared to the DAC-heavy 2022 Scoping Plan. However, scenarios with limited forest biomass availability fail to meet the target. The report highlights a trade-off between optimizing biomass for CDR versus sustainable aviation fuel (SAF) production and recommends expanding the state's CDR portfolio beyond hydrogen-based BECCS.

Exploring Biomass Carbon Removal and Storage (BiCRS) Scenarios for California
The report explores the potential of Biomass Carbon Removal and Storage (BiCRS) to help California meet its 2045 CDR target of 75 MMT CO2e. By modeling seven scenarios based on cost and social acceptance, the analysis finds that BiCRS could potentially meet the entire target under high biomass availability estimates without competing with food production. The report highlights that while lower-cost pathways rely on established technologies like combustion with CCS, higher social acceptance pathways require advanced technologies such as pyrolysis and gasification. BiCRS is projected to generate significantly more bioenergy and jobs than the current direct air capture (DAC)-focused Scoping Plan.

Companies role in scaling up DURABLE CARBON DIOXIDE REMOVALS
The report finds that while durable CDR (storage >1,000 years) is essential for neutralizing fossil emissions, corporate uptake is low and concentrated among a few companies, notably Microsoft. Many companies instead rely on non-durable CDR, which the authors argue is unsuitable for neutralizing long-cycle emissions. The report highlights risks of double counting between companies and governments and a systemic lack of transparency regarding the environmental and social impacts of CDR projects. It recommends that voluntary initiatives like SBTi require companies to set separate monetary and removal targets based on ability to pay, rather than merging them into net-zero goals.

CRCF Draft on Permanent Carbon Removals Lacks Scientific and Environmental Integrity
A coalition of NGOs, including Carbon Market Watch, warns that the European Commission's draft delegated act for permanent carbon removals—covering DACCS, BioCCS, and biochar—fails to meet the legal requirements of the CRCF regulation. The group argues the methodologies are of low quality, fail to address indirect land use change, assume automatic additionality, and lack sufficient MRV and liability rules for biochar. They call on the European Parliament and Council to object to the draft and urge the Commission to prevent the integration of these units into the EU ETS until quality is ensured.
