Heavyweights back proposals to set legal limits on embodied carbon

Proposals to put legal limits on embodied carbon in construction projects have been backed by a group of industry heavyweights including Allies & Morrison, Feilden Clegg Bradley Studios and Arup.

The proposals would see an amendment made to the Building Regulations setting mandatory limits for upfront carbon emissions on all building projects over 1,000sq m from 2027.

被称为Z部分的修正案还要求建筑公司从2023年开始评估并报告所有超过1000平方米的非住宅建筑项目的全寿命碳，从2025年开始报告住宅项目的全寿命碳。

Arup UK net zero buildings leader Chris Carroll said “firm, supportive legislation” is needed to set out a clear requirement to measure, report and reduce carbon to aligned targets.

The group of 18 signatories also includes RIBA, developer Grosvenor, engineer WSP and contractors Laing O’Rourke and Bam.

Grosvenor executive director for sustainability and innovation Tor Burrows said that embodied carbon had been “hidden” in the built environment for too long.

“随着今天的呼吁，行业要求监管，以确保每一个重大的英国发展跟踪和限制其全部碳足迹。

“We already do this for our large development projects and the time is right to introduce legislation for the whole industry.”

The proposals come after the Climate Change Committee published its latest report to parliament on net zero progress.

The June report urged the government to set out plans for phasing in mandatory whole life carbon reporting and limits for all buildings, roads and infrastructure by 2025.

A number other countries have introduced such laws in recent years including the Netherlands and France, and the USA is drafting similar legislation.

But the group of signatories for the Part Z proposals argue that while those countries have needed several years to work out how embodied carbon can be assessed, the UK is in the “unique position” of having most of the tools needed already up and running.

自2017年以来，英国皇家特许测量师学会的全寿命期碳评估指导文件已被业界使用，目前正在开发的Built Environment carbon Database将成为评估项目中隐含碳的关键来源。

Joe Giddings, campaigns coordinator of Architects Climate Action Network (ACAN) said: “It’s great to see such wide industry support behind the key demand of our campaign to regulate embodied carbon. We called on the government to introduce ‘Part Z’ back in February, and just six months later this group has now drafted the regulation for them to introduce. It now couldn’t be easier for the government to act, and they must act now.

”We proposed a much faster timeline than has been set out in this draft regulation, as we believe it is necessary to introduce strict limits on embodied carbon emissions on all new buildings from 2025 at the latest. We hope in time we’ll have the opportunity to engage with this group, and the government, to put our arguments forward for the rapid change that we believe is necessary to mitigate the worst of climate change.

”We will continue to engage with policymakers and have already had some constructive conversations with political parties including SNP and the Green Party, as well as MPs from other parties.”
