Beyond the Pledge: Building a Credible Net Zero Pathway

The Climate Pledge has crossed 700 signatories, companies committing to reach net zero carbon emissions by 2040, a decade ahead of the Paris Agreement's 2050 target. The milestone reflects genuine momentum. It also reflects a pattern that is now well established in corporate climate commitments: the number of companies making net zero pledges consistently outpaces the number that have built the operational infrastructure to deliver on them.

This is not a criticism of the signatories. The decision to make a public, time-bound net zero commitment is a meaningful governance act that creates real accountability. The question is what happens after the signing, and the evidence from the broader universe of corporate net zero commitments is not uniformly encouraging.

The Gap Between Commitment and Infrastructure

Research into corporate net zero commitments consistently finds the same structural gap. Companies announce targets. Fewer conduct the detailed emissions baseline work required to understand what reaching those targets actually demands. Fewer still integrate decarbonisation into capital allocation, procurement decisions, and supplier contracts in ways that make the pathway operationally credible. And a substantial proportion rely on carbon offsets as a material part of their net zero pathway in ways that, under tightening scrutiny from regulators, investors, and the courts, are increasingly difficult to defend.

The Climate Pledge's 2040 timeline is more demanding than the 2050 baseline, which concentrates the problem. A company committing to net zero by 2040 has roughly 14 years to decarbonise an operational footprint that, in most cases, has taken decades to build. That timeline is achievable for some sectors and genuinely difficult for others. The pledge does not differentiate by sector, which means the credibility of a technology company's 2040 commitment and a heavy industrial manufacturer's 2040 commitment are not equivalent, even if they appear on the same list.

What a Credible Pathway Actually Requires

The distance between a signed pledge and a credible transition plan is where most corporate net zero commitments currently sit, and it is larger than most boards appreciate.

A credible 2040 net zero pathway requires, at minimum, a verified Scope 1 and 2 emissions baseline that can withstand independent audit. It requires a Scope 3 assessment that maps material emissions across the value chain, because for most companies, more than 70% of their total carbon footprint sits outside their direct operations. It requires a sector-specific decarbonisation pathway that identifies which emission sources will be reduced through operational change, which require capital investment in new technology or infrastructure, and which, if any, will be addressed through high-quality carbon removal as a last resort for genuinely hard-to-abate residual emissions.

It requires that pathway to be connected to actual capital allocation decisions, not held separately in a sustainability strategy document. And it requires interim milestones that are specific, measurable, and reported against annually, so that progress or the absence of it is visible to investors, customers, and regulators before 2040 arrives.

Most Climate Pledge signatories, at the point of signing, have none of this fully in place. That is not unusual or scandalous. It is the normal starting point. The risk is treating the pledge as the destination rather than the beginning.

The Accountability Architecture Is Getting Stricter

The environment in which these commitments will be assessed over the next 14 years is materially different from the one in which earlier net zero pledges were made.

Mandatory sustainability reporting requirements now cover a significant proportion of large companies in Europe, with equivalent frameworks developing across Asia and under consideration in multiple other jurisdictions. Transition plan disclosure is increasingly a formal requirement rather than a voluntary addition. Carbon accounting standards have tightened, reducing the scope for companies to present flattering emissions figures through creative boundary-setting. And climate litigation is establishing that public net zero commitments can carry legal weight, particularly in jurisdictions with duty of vigilance or due diligence frameworks.

The 700 companies on the Climate Pledge list will be disclosing their progress against a 2040 target through frameworks and to regulators that did not exist when the earliest signatories joined. The commitment they are making is not just to the state of accountability that exists today. It is to the state of accountability that will exist in 2030, 2035, and 2040, which will be considerably more demanding.

The Strategic Opportunity Inside the Accountability Challenge

There is a version of this story that is not about risk but about competitive positioning, and it is the version that the most strategically sophisticated signatories are internalising.

A company that builds a genuine, operationally grounded net zero pathway in the next two to three years is not just managing regulatory and reputational risk. It is building supply chain visibility, energy cost resilience, access to green finance at better terms, and procurement credibility with customers who are themselves under pressure to decarbonise their value chains. These are structural commercial advantages that compound over time and that competitors who treat their net zero pledge as a communications exercise will not have.

The 700 companies on the list are not a homogeneous group. Some will build the infrastructure. Some will issue periodic progress reports against targets they have not operationalised. The distance between those two groups will be visible by 2030 and decisive by 2035. The pledge is the starting line, not the finish.

How Aranca Can Help

Aranca's Net Zero and Decarbonisation Transformation practice helps organisations move from net zero commitment to credible, operationally grounded transition strategy, developing verified emissions baselines, science-based targets, sector-specific decarbonisation pathways, and capital expenditure plans that connect climate ambition to real business decisions. If your organisation has made a net zero commitment and is now building the strategy to deliver it, we can help you do that with the rigour the accountability environment increasingly demands.
