The Need for Corporate Decarbonisation Guidelines to Reach Global Net Zero

Corporate decarbonisation has been held back to date by unclear rules. In many jurisdictions, doing nothing can appear safer than acting, because the risk of making a 'wrong' claim or buying the 'wrong' instrument feels higher than the risk of delay. The result amongst some companies has been paralysis. Investment stalls, and emissions persist. Clear, consistent guidelines could unlock credible action at scale, as recently proposed by VCMI in their recent research supported by Accenture - "A Confident Carbon Market: Business Perspectives".

Global Net Zero to Corporate Action

The Paris Agreement sets the destination - global net zero by around mid-century to limit warming in line with 1.5-2℃º. It does so at the jurisdictional level: parties submit Nationally Determined Contributions (NDCs) that define national targets, usually with sectoral coverage and scope for mitigation.

Those national targets translate to the corporate level in two ways. First, regulated entities are directly covered by domestic policies (e.g. emissions trading systems or carbon taxes) that operationalise the NDC. Second, all other companies still contribute to the national inventory through the aggregates of emissions including their Scope 1–3 emissions and will increasingly face policy, market, and supply-chain pressures to align with the jurisdiction’s decarbonisation pathway. In short: the Paris Agreement defines the goal; NDCs turn it into national plans; domestic policy turns plans into obligations; companies then act within that framework.

Mechanisms for Corporate Decarbonisation

From NDCs flow compliance instruments that set formal rules:

• Carbon taxes put a price on emissions directly
• Emissions Trading Systems (ETSs) cap emissions and allocate/auction allowances
  • Free allocation inside ETSs functions as permission to emit without immediate cost, effectively delaying internal abatement within leakage-risk sectors.
• Revenues from taxes and ETS auctions may be earmarked for public decarbonisation spending, but outcomes can be diffuse and hard to quantify at the company level.

These compliance levers force organisations to consider their options; either internal emissions abatement or payment. In parallel, carbon credits can channel private finance into measurable reductions or removals outside an organisations’ boundary subject to quality rules (additionality, durability, robust measuring, reporting and verification) and, increasingly, alignment with national accounting under Article 6. Without clear guidance, however, corporates can struggle to decide when and how credits complement, rather than substitute for, real operational decarbonisation.

The Unregulated Emissions

Not all emissions are covered by current policy:

• Out-of-scope in NDCs: Some sectors or gases remain partially or wholly outside near-term national targets
• Conditional NDC components: Many countries pledge deeper cuts 'conditional' on international finance, inviting private capital
• Outside ETS/tax scope: Large portions of the economy (SMEs, upstream value chains, international supply chains) sit beyond direct compliance signals.

These gaps are precisely where high-integrity voluntary action can accelerate progress, provided claims are disciplined and transparent, and purchases do not undermine domestic targets.

What the Future of Corporate Action Could Look Like

Emerging guidance is converging on a balanced model:

1. Align with targets first. Setting near-term and net-zero targets aligned with science and the host jurisdictions' pathways.
2. Abate what you can control. Prioritising Scope 1 and 2 reductions and material Scope 3 levers in line with sectoral pathways.
3. Comply fully. Meet all ETS and carbon tax obligations; treat free allocation as temporary and publish a declining free-allocation schedule aligned to a quantified reduction pathway.
4. Contributing beyond compliance with integrity. Using high-quality credits to address residual and out-of-scope emissions separately from compliance and without claiming equivalence to internal abatement.
5. Make disciplined claims.
   • VCMI: The VCMI Claims Code provides guardrails for making claims when credits complement credible targets and transition plans. VCMI also offers a Scope 3 pathway/claim format;
   • SBTI: The Science Based Targets initiative (SBTi) is the cornerstone for setting science-aligned targets and driving internal decarbonization. The use of certificates is currently under review, with SBTi looking to include these in their guidance. Companies should align with SBTi’s Corporate Net-Zero Standard or another net-zero standard when making claims. Report with precision. Disclose: (a) gross emissions, (b) reductions achieved, (c) compliance instruments surrendered, (d) voluntary credits purchased and retired (type, vintage, programme, methodology, host country, authorisation status), and (e) the claims you make and do not make.

Bottom Line

Clear, public, and enforceable corporate guidelines can align internal abatement, compliance, and high-integrity voluntary contributions into one coherent plan. This removes the perceived legal and reputational risk of acting, and replaces today’s ’safer to wait’ position with confident execution that supports both corporate strategy and national progress towards Paris-aligned net zero.
