The Taskforce on Scaling Voluntary Carbon Markets (TSVCM) was a private sector-led initiative sponsored by the Institute of International Finance (IIF) that produced recommendations intended to scale the voluntary carbon market and increase confidence in the integrity of carbon credits used for voluntary climate-change mitigation claims. The initiative was initiated by Mark Carney and chaired by Bill Winters. Between 2020 and 2021 it published consultation materials and reports proposing baseline integrity criteria (the Core Carbon Principles) and associated governance and market-infrastructure arrangements intended to support a larger, more standardised market. In 2021 the initiative announced a new governance body to take forward its integrity-benchmark work; that body later adopted the name Integrity Council for the Voluntary Carbon Market (ICVCM). The taskforce's proposals received public attention and prompted debate about market governance, including concerns about independence and representation of Indigenous peoples and local communities in oversight.
Background Voluntary carbon markets involve carbon credits issued and traded outside mandatory (compliance) emissions-trading systems; credits are widely used in corporate and organisational climate strategies, including to support claims about compensating or neutralising emissions. Academic and policy analysis has repeatedly highlighted integrity and transparency risks in these markets, including uncertainty about whether credited outcomes are additional, how baselines are set, and whether risks such as leakage, non-permanence and double counting are managed consistently across different credit types and jurisdictions.
Terminology In the voluntary carbon market, a carbon credit is commonly treated as a unit representing one tonne of CO2-equivalent reduced or removed, and an offset is the use of credits to compensate for emissions elsewhere in an organisation's footprint. Integrity concepts discussed in this context include additionality and controls to reduce double counting. TSVCM's documentation used these integrity concepts in proposing market-wide benchmarks meant to apply across different standards and project types rather than creating a single new crediting programme.
Academic and policy analysis Academic and policy literature has discussed a tension between scaling voluntary carbon markets and maintaining credibility, emphasising how heterogeneous project types, fragmented governance and information asymmetries can make credit quality difficult to assess and can create incentives for low-integrity supply and weak disclosure. Work focused on disclosure has argued that stronger transparency, supported by standardised and accessible project and credit data, can improve scrutiny and accountability for carbon credit mechanisms and associated claims. Legal and policy analysis of corporate offsetting has debated how credits should be used in net-zero strategies, including concerns that weak governance and disclosure can enable misleading claims or reduce pressure for direct emissions reductions. In this context, TSVCM presented its reports as a reform approach focused on common integrity principles and governance arrangements intended to enable market growth while addressing quality and confidence concerns.
Establishment TSVCM was convened in September 2020 and released initial recommendations in November 2020 as part of its stated aim to support the development of a larger voluntary carbon market with improved integrity and transparency. Contemporaneous reporting described the initiative as an effort to develop market-wide rules and infrastructure for voluntary carbon credits, including integrity criteria intended to raise confidence in voluntary offsetting and related claims.
Leadership and participation TSVCM described itself as initiated by Mark Carney and chaired by Bill Winters, with an operating lead and supporting structures for its work programme. Its initial materials described a taskforce drawing participants from multiple sectors, together with a broader consultation group that included financial institutions, market infrastructure providers and buyers and suppliers of carbon credits. In March 2021 the initiative announced an advisory board and working groups for its development and implementation phase, describing these as intended to incorporate technical and market input across the voluntary carbon market value chain, including engagement with civil society and academia. Media reporting described participation by major financial institutions and other market actors, alongside criticism from some civil-society organisations focused on governance design and potential conflicts of interest in proposed oversight arrangements. As part of its governance proposals, the initiative sought candidates for a new governance body intended to provide independent oversight and integrity benchmark-setting for the voluntary carbon market.
Workstreams and process TSVCM described its work as moving from a design phase to a development and implementation phase supported by an advisory board and working groups, with draft proposals released for public consultation and feedback summarised in a consultation report. It established three working groups with remits covering governance, legal principles and contracts, and credit-level integrity, including work on proposed Core Carbon Principles and market infrastructure recommendations.
Governance: identification of governance gaps and options for addressing them, including approaches for establishing (or using existing) governance bodies. Legal principles and contracts: development of standard contract mechanics and templates intended to support trading of carbon credits. Credit-level integrity: development of threshold standards intended to raise credit quality, including through the proposed Core Carbon Principles.
