RIBA to publish whole-life carbon data for 2026 Stirling Prize shortlist

RIBA has confirmed it will publish whole-life carbon data for all six buildings on the 2026 Stirling Prize shortlist. The move follows pressure from Architects Climate Action Network (ACAN), whose Less Taste: More Metrics campaign argues that awards should weigh environmental performance alongside aesthetics. The data will appear on the RIBA Journal site before the ceremony on 15 October. Starting next year, all entries to RIBA national awards will need to submit this data. Whole-life carbon includes both upfront embodied carbon and operational emissions. Of the six shortlisted projects, only Bennetts Associates' BEAM venue has publicly shared its figures, reporting 602 kgCO₂e/m² for upfront carbon (A1-A5). RIBA says the data is reviewed by sustainability experts at multiple stages, but there is no fixed weighting or pass/fail threshold against benchmarks like the 2030 Climate Challenge. ACAN chair Jeremy Till argues that a building cannot be considered the best if it fails the institute's own climate standards.

Finally some real numbers on the Stirling shortlist. It's good that RIBA will publish whole-life carbon data, but they already collected it this year and sat on it. Only Bennetts had the guts to share their own numbers upfront. Still, a step in the right direction for making awards accountable to climate impact.

Agree. ACAN's campaign clearly pushed this forward. The whole-life carbon metric is key because buildings are a huge chunk of global emissions. Publishing data is one thing, but what about verification? RIBA admits they don't have a fixed system to check accuracy. That could be a problem.

Yeah, the verification issue is real. If the data isn't independently checked, it's just self-reported numbers. And without a fixed weighting, how do they compare projects? One building could have 600 kgCO2e/m2 and another 300, but both get the same treatment. That seems sloppy for a prize that's meant to set a standard.

RIBA says the data will be published on ribaj.org before the ceremony. Good to see some transparency. The fact that they'll require this for all national award entries next year is a bigger deal. It normalizes carbon reporting across the industry, not just for the big prize.

Requiring data is fine, but without benchmarks or enforcement it's just paperwork. ACAN wants projects that miss the 2030 Climate Challenge to be excluded. RIBA says they won't exclude or downgrade. So what's the point? Publishing numbers that no one acts on is greenwashing by disclosure.

Exactly. For buildings, embodied carbon is the big one because it's locked in before operation. If RIBA doesn't use these numbers to actually influence the winner, the whole exercise is cosmetic. They need to set a threshold and stick to it. Otherwise it's just a PR move.
