The corporate net zero playbook is reaching its limits
For years, corporate net zero has been framed as a matter of ambition: set a target, measure your footprint, engage suppliers, reduce what you can, and neutralize what remains.
That framing made sense when the corporate climate movement was still focused on target-setting and measurement. But the companies furthest along are now running into a harder reality: Scope 3 is not just an ambition problem. It is an architecture problem.
Scope 3 emissions are distributed across suppliers, multiple tiers of production, changing commercial relationships, and global commodity systems that no single buyer controls.
Scope 1 and Scope 2 were the easier part
Scope 1 and Scope 2 emissions are usually more directly manageable. A company can improve operational efficiency, electrify equipment, purchase renewable electricity, or change how its facilities are powered.
Scope 3 is different. It asks companies to influence emissions that occur outside their operations, often several steps upstream or downstream from direct commercial relationships.
Why the current Scope 3 model breaks down
| Assumption | Reality |
|---|---|
| Companies can trace their full upstream supply chain. | Supply chains are dynamic, multi-tier, and often opaque beyond direct suppliers. |
| Direct suppliers can pass climate pressure upstream. | Supplier influence often weakens as it moves toward commodity producers. |
| Better data will solve the problem. | Data helps, but it does not automatically finance lower-carbon production. |
| Every company can decarbonize its own value chain independently. | Many companies depend on shared industrial systems that require aggregated demand. |
| Supplier engagement alone can transform hard-to-abate sectors. | Industrial transformation requires revenue certainty, market demand, and investable signals. |
The lesson is not to abandon net zero
The right conclusion is not that corporate net zero should be abandoned. The right conclusion is that the playbook needs to evolve.
Companies should still measure, reduce, and engage suppliers. But the next phase of Scope 3 climate action needs mechanisms that move beyond company-by-company supply chain micromanagement.
Where S3 Markets fits
S3 Markets is built around this insight. If Scope 3 emissions are concentrated in hard-to-abate commodity systems, then companies need a way to support verified low-carbon production in those systems, even when they do not directly purchase the physical commodity.
Commodity Environmental Attribute Certificates create a way to aggregate demand, direct capital toward lower-carbon production, and document the action through a trusted system of record.
