Firm also pledges to withdraw from energy schemes involving fossil fuels
奥雅纳has committed to undertaking whole lifecycle carbon assessments for all its buildings projects – new and retrofit – from next year.
It also announced it will not take on any new energy schemes involving fossil fuels anywhere in the world from April.
The firm said it will withdraw from all jobs which involve the extraction, refinement or transportation of hydrocarbon-based fuels as part of its net zero goals.
Instead, it will only accept commissions in low-carbon energy projects which “advance progress toward a fully decarbonised future” such as wind, solar, hydroelectric and hydrogen.
Studies will estimate the total amount of carbon emissions generated from its buildings, both new and retrofit, over the course of their lifespans.
They will include both operational carbon, which is emitted by the building itself during its use, and embodied carbon, which is generated from the manufacturing and transport of materials during construction.
The firm added it will develop a way to apply the same assessments to its infrastructure work “without delay” and has pledged to make “significant” investment in staff training.
It said the insights it will gain from conducting “thousands” of the studies each year will help the construction industry advance towards net zero emissions.
奥雅纳Group chair Alan Belfield said whole-life carbon assessments were the next step that must be taken to decarbonise buildings “at scale”.
他补充说:“我们承诺对所有的建筑工程进行全寿命周期的碳评估，这意味着我们将首次与客户和行业合作伙伴分享数据，以最有效地降低建筑(无论是新建还是现有)的碳排放。”
World Green Building Council chief executive Cristina Gamboa said the move was “game-changing”. She added: “Delivering net zero buildings requires transformative action by industry leaders”, adding that Arup’s commitment “will help to accelerate the buildings sector’s progress toward net zero”.
Last year, Arup pledged to hit net zero across all of its global operations by 2030. It is also a supporter of proposals to write mandatory whole-life carbon emissions for all major schemes into UK building regulations.
It is the latest in a string of architects, engineers and other firms to make commitments around net zero. In 2019Penoyre & Prasad pledgedto essentially design projects twice in order to give clients a free costed report detailing how their building could be zero-carbon.
The same yearGrimshaw committedto all its design work being net zero carbon-ready within the decade.

与此同时，澳大利亚建筑公司wagner表示，它将把伦敦作为一种新型可持续混凝土的全球平台。
Known as Earth Friendly Concrete, it contains around 70% less embodied carbon than normal concrete and saves 250kg carbon for each cubic metre poured.
近3立方公里的材料已经在HS2上用于临时打桩垫、运输道路和起重机基地。
建筑环境的碳排放量占全球近40%，仅混凝土就产生了全球约8%的碳排放。
Wagners said that the new concrete also includes improved durability, lower shrinkage, earlier strength gain, higher tensile strength and increased fire resistance.
