Charting a Unique Course for Climate Action in the UK

The United Kingdom has legally enshrined its commitment to achieving Net Zero by 2050 - a binding target that is reshaping its entire economic and energy framework. While a robust compliance structure, including the UK Emissions Trading Scheme (UK ETS), regulates a significant proportion of emissions from the industrial and power sectors, a thriving and increasingly sophisticated Voluntary Carbon Market (VCM) is playing a vital complementary role.

Operating in a post-Brexit context, the UK’s VCM has followed a distinct path - driven by ambitious corporate climate commitments, the strength of the City of London as a global green finance hub, and a nuanced approach to carbon credit quality and integrity.

This article explores the specific contours of the UK’s VCM. We assess the key drivers motivating British companies to engage in voluntary offsetting, the types of projects they favour, and how global VCM standards interact with domestic climate objectives. Critically, we also examine the impact of Brexit on the UK’s VCM, its relationship with compliance markets, and the essential role expert partners such as AFS Energy play in guiding businesses through this evolving landscape to ensure their climate contributions are credible, impactful, and aligned with Net Zero.

The UK’s Net Zero Imperative and the Role of the VCM

The UK's statutory Net Zero target and its series of interim carbon budgets are major drivers of action across all sectors. While the UK ETS mandates reductions from covered entities, large segments of corporate emissions remain outside its scope, especially:

• Scope 3 Emissions: Indirect emissions across the value chain (e.g., procurement, business travel, product use), which often account for the largest share of a company’s emissions and are not covered by the UK ETS.
• Residual Emissions: Emissions that are not yet technically or financially feasible to abate.
• Beyond Value Chain Mitigation: A growing interest in supporting global climate action, including investment in projects that deliver verifiable emissions reductions or removals outside the company’s own operational footprint.

The VCM offers UK companies a strategic avenue to address these gaps by:

• Advancing Net Zero Commitments: Offsetting residual or Scope 3 emissions to close the gap between internal abatement efforts and full Net Zero goals.
• Enhancing ESG and Brand Value: Meeting rising investor and stakeholder expectations for transparency, sustainability, and ethical leadership.
• Supporting Climate Innovation: Channeling finance into carbon removal technologies and nature-based solutions aligned with corporate values and wider environmental objectives.

Demand Drivers and Preferred Projects for UK Buyers

British companies are active, sophisticated participants in the VCM, reflecting maturing strategies and increasing scrutiny. Their preferences include:

• Commitment to High-Integrity Credits: As in Europe, UK buyers demand robust credits that demonstrate clear additionality, permanence, and rigorous monitoring and reporting. Given the intense media and regulatory scrutiny in the UK, greenwashing concerns are a major risk and must be proactively mitigated.
• Rising Demand for Carbon Removals: There is a growing shift towards removals-based credits - including Direct Air Capture, biochar, and high-quality afforestation/reforestation - recognised as critical for managing residual emissions on the journey to Net Zero.
• Emphasis on Nature-Based Solutions (NBS): UK buyers show strong interest in NBS, especially those enhancing biodiversity, improving water quality, and delivering community co-benefits, both within the UK and globally.
• Strong Interest in Biogas Projects: Biomethane projects, particularly those capturing methane from waste streams (e.g., agriculture, landfills, wastewater), are highly valued due to:
  • Significant GHG Reductions: Methane is a potent greenhouse gas, and its capture yields substantial verified emission savings.
  • Clear Additionality: These projects often depend on carbon finance for viability, especially in developing economies.
  • Co-Benefits: They address waste management challenges, reduce pollution and odours, and generate clean energy.
  • Circular Economy Alignment: Converting waste into energy or fertiliser fits with the UK's commitment to resource efficiency and closed-loop systems.

Certification and Standards: Global Alignment with a UK Lens

The UK VCM primarily utilises globally recognised standards for credit issuance and verification:

• Verra (VCS): The most widely used and generally accepted standard among UK buyers.
• Gold Standard (GS): Favoured for its strong emphasis on sustainable development and stakeholder engagement - values that align with UK corporate responsibility.
• Other Standards: Programmes like ACR and CAR are also used, particularly for credits from North American projects.

‍

UK-Specific Initiatives and the Domestic Market

While international standards dominate for overseas projects, the UK has cultivated its own domestic certification frameworks:

• Woodland Carbon Code (WCC) & Peatland Code: Voluntary UK standards for woodland creation and peatland restoration, offering verified carbon units for British buyers wishing to support local sequestration projects.
• Developing Domestic Removals Market: Government efforts are underway to stimulate a UK-based carbon removals sector, potentially influencing future demand for domestically certified projects and enhancing national climate resilience.

‍

Regulatory Interaction: Post-Brexit Autonomy and Market Integration

Following Brexit, the UK has carved out a distinct regulatory environment for its carbon markets:

• Independent VCM Governance: The UK’s VCM now operates separately from EU frameworks, enabling tailored policy development but removing automatic mutual recognition of credits between the UK and EU.
• UK ETS: Functioning similarly to the EU ETS, the UK ETS governs direct emissions from large emitters. Voluntary carbon credits are used to address emissions outside its scope (e.g., Scope 3), or to go beyond regulatory compliance.
• Renewable Transport Fuel Obligation (RTFO): A compliance mechanism for the transport sector. While RTFCs differ from VCM credits, both monetise emissions reductions - often from similar projects such as biomethane production.
• Green Gas Support Scheme (GGSS): Provides incentives for injecting biomethane into the UK gas grid. Green Gas Certificates (GGCs/RGGOs) issued under this scheme support voluntary green gas claims in heating and industry.
• Green Finance Leadership: London’s status as a global financial centre places UK corporates under heightened pressure to disclose robust ESG and carbon strategies. This increases demand for credible VCM engagement and adherence to best-practice disclosure frameworks.

Challenges and Opportunities for the UK VCM

Challenges

• Perception of Greenwashing: In a highly scrutinised market, any hint of insincere offsetting can be reputationally damaging. Companies must exercise rigorous project selection and transparent communications.
• Supply of High-Quality Credits: Ensuring adequate access to high-integrity removal and avoidance credits - both international and UK-based - is a persistent challenge.
• Navigating Multiple Standards: The UK VCM must remain aligned with evolving international frameworks like ICVCM and VCMI, despite operating independently.
• Complex Credit Interactions: Businesses need clarity on how UK ETS, RTFO, GGSS and the VCM interconnect, and how to avoid double-counting across schemes.

Opportunities

• Net Zero Legislation as a Driver: The UK’s binding Net Zero commitment propels sustained demand for VCM engagement as part of broader corporate climate strategies.
• Innovation in Green Finance: London’s financial ecosystem enables novel carbon finance models and rapid growth in ESG investment, fostering a vibrant market for high-quality credits.
• Domestic Project Growth: Expanding support for UK-based carbon removal and biomethane projects opens new opportunities for locally sourced voluntary offsets.
• Climate Disclosure Leadership: The UK’s emphasis on transparent reporting (e.g., TCFD alignment) promotes best-in-class practices in voluntary offsetting.
