Conclusion (the committee's words)
The post-Grenfell prohibition on the use of combustible materials in external walls has had a disproportionate impact on the use, innovation and testing of structural timber. Material safety perceptions have also affected the availability and cost of insurance, making it near impossible for developers to use timber in high rise or medium-rise buildings. There has been a substantial delay in the Government’s response to its consultation on amendments to the combustible materials ban, 68 Building to net zero: costing carbon in construction which closed in May 2020. This delay is unacceptable: it has left the construction industry without the guidance and confidence it needs to invest in timber structures.

Government response
The government responded to the whole report on 30 September 2022 (deadline 26 July 2022).
Summary written by Accountability Index from the government's response. It is not the government's own words.The government agrees that whole-life carbon assessments are "likely to have a significant role" in decarbonising construction, but it does not commit to mandating them and says it will consult on its approach to embodied carbon in 2023.
- On a mandatory requirement, it "intends to consult in 2023" and will "consider" what levers, including building regulations, will be needed. It says it is "too soon to commit" to ratcheted carbon targets.
- It agrees a standardised calculation method is required and "will look at whether" endorsing specific standards, methodologies or tools "is appropriate".
- It declines to bring forward the Future Homes Standard to 2023, stating it "will not look to alter the timeframe" and that the 2025 timeline delivers on net zero commitments while ensuring homes are delivered in sufficient numbers.
- On public procurement, it says the Procurement Bill would not be an appropriate place for net zero policy priorities, and that there are "no plans to collect and publish" data on whole-life carbon assessments under the Construction Playbook.
