Most net-zero commitments fail not at ambition but at the financing conversation. A public target with no funded pathway is a liability with a date on it. The difference between a pledge and a plan is concrete and financial: a marginal abatement cost curve, a sequenced capital plan, and financing identified for the levers that need it. Get those three right and net zero becomes a capital-allocation decision the CFO can actually make.
Why most plans stall at the CFO
Boards reject net-zero plans for predictable reasons: the levers are not costed, they are not sequenced, and no one has shown where the money comes from. A roadmap that does not change the capital plan is decoration. The work is to express decarbonisation in the language finance already uses — cost per tonne, NPV, payback, and impact on the cost of capital.
The marginal abatement cost curve
The marginal abatement cost curve (MACC) ranks every viable lever by its cost per tonne of CO2 avoided, against your own hurdle rate. The honest revelation for most companies is that a substantial share of early levers — energy efficiency, renewable procurement, electrification — are cash-positive at current energy prices. They do not cost money; they save it. The MACC is what turns an abstract target into a ranked, fundable list.
Sequencing for finance-ability
Sequence deliberately: harvest the cash-positive levers first, and let their savings part-fund the harder, later ones. Pilot the expensive levers early (process heat, feedstock change, fleet) but time the heavy capital to natural asset-replacement cycles rather than forcing premature write-offs. Sequencing against asset life is the single biggest cost saver in any industrial decarbonisation plan.
The financing toolkit
- Green bonds: proceeds ring-fenced for defined green projects, under the ICMA Green Bond Principles.
- Sustainability-linked loans and bonds: financial terms (the coupon or margin) tied to achieving sustainability KPIs, under the relevant Sustainability-Linked Principles.
- Transition finance: instruments aimed specifically at hard-to-abate decarbonisation.
- Internal carbon pricing: a shadow price that makes low-carbon options compete fairly inside capex and procurement decisions.
Building the business case
Frame each lever in financial terms — NPV, payback and cost-of-capital effect — and, crucially, price the cost of inaction: rising carbon prices, CBAM exposure, lost market access, and financing that gets more expensive for laggards. The strongest business cases show that the unsequenced, unfunded path is the expensive one.
Governance, delivery and disclosure
Attach owners, milestones and a review cadence, and package the result as a transition plan in the format that CSRD and IFRS S2 increasingly expect. A credible, disclosed, funded transition plan does double duty: it directs capital internally and signals to lenders and investors that the company is financeable on better terms.
