From labels to audits, 3 eras of Corporate Net-Zero thinking

Corporate net-zero planning is having a moment of intense scrutiny. The SBTi Net-Zero Standard v2, the ISO Net Zero draft, the GHG Protocol's AMI working group - all of these are converging at once, each trying to answer the same underlying question: what does it actually mean for a company to be "good" on climate?

That convergence of debate is a good excuse to zoom out. Looking back over the past 15 years, corporate climate thinking hasn't evolved in a straight line so much as moved through distinct eras, each defined by a different answer to the question "what counts as credible?" Understanding where we've been makes it a lot easier to see where we're headed.

2010–2020: The Label Era

For most of the 2010s, credibility was a matter of vocabulary. A company earned its climate credentials by carrying a label - Carbon Neutral, Climate Neutral, Net Zero - and the label itself did the work of signaling virtue. If you had the badge, you were "good."

The problem, as our collective understanding of climate science matured, is that the labels didn't hold up to scrutiny. It became clear that no company today is truly climate neutral, regardless of which specific claim it was making. Offsets papered over ongoing emissions, definitions were inconsistent, and the label told you almost nothing about what a company was actually doing to reduce its footprint. The era didn't end because companies were acting in bad faith - it ended because the label itself stopped being a meaningful proxy for credibility.

2020–2030: The Target Era

The era we're currently in shifted the goal in an important way. A "good" company today is not expected to claim it's already net zero - it's expected to be honest that it isn't, while setting a science-based target and laying out a credible transition pathway. That reframing was genuine progress: it replaced a static, often misleading claim with a forward-looking commitment that could be measured against a science-based benchmark.

But a target is a promise, not a result. We're now learning just how hard that promise is to keep. Even companies with the best of intentions are struggling to deliver, largely because so much of their emissions footprint sits outside their direct control. That's the entire premise of scope 3: your biggest climate exposure is often your suppliers' and customers' behavior, not your own. This gap between ambition and control has fueled an increasingly technical set of debates - over market-based instruments, conditional versus unconditional targets, in-value-chain mitigation, and a dozen other implementation questions that didn't exist when the targets were first set. The target era gave companies a credible destination. It didn't give them an easy road to get there.

2030–...: The Audit Era

Looking ahead, the center of gravity is expected to shift again - away from labels and away from promises, and toward trusted, independently verified reporting. In this next era, a "good" company won't be one that carries the right badge or has announced the right target. It will simply be one that transparently reports its actual emissions, verified by an independent third party.

That shift hands the interpretive work back to the people who actually need it: investors, customers, regulators, and other stakeholders can take that reliable information and make decisions appropriate to their own context, rather than relying on a company's self-selected framing of its own progress. This isn't a hypothetical - it's already the philosophy underpinning the CSRD. And in many ways, it's simply how financial reporting has always worked: not by making claims about a hoped-for future, but by providing a fair and reliable picture of where a company actually stands today.

Conclusion

Fifteen years, three eras, one consistent trend: each phase has stripped away a layer of self-declared credibility and replaced it with something more rigorous - from a label, to a target, to an audited number. That's not a story of climate ambition fading. It's a story of the goalposts moving toward greater accountability every step of the way.

If that trajectory holds, the companies best positioned for what's coming aren't the ones with the flashiest labels or the most ambitious targets on paper - they're the ones already building the systems to measure, report, and verify their emissions accurately. The audit era rewards precision, not promises. Getting there early isn't just good practice; it's a hedge against the scrutiny that's already on its way.
