An international coalition of construction experts has published the world’s first universal standard for reporting carbon dioxide emissions used in the building and lifecycle of structures – also known as ‘embodied and operational carbon’ within the industry.
The International Cost
Management Standard – or ICMS3 – sets out a methodology for construction
professionals and developers to account the amount of embodied carbon their
projects will create, whether that’s through the delivery of new roads,
schools, offices, housing or railways.
An estimated 40% of global
carbon emissions are emitted every year through the construction of new
buildings and infrastructure, and the industry has accepted it must adapt in
order to meet the pressing need to avert climate catastrophe.
The launch of ICMS3
represents the starting pistol being fired for the construction sector to
embrace net-zero as a global, interconnected industry, and follows the COP-26
climate conference in Glasgow (UK) where world leaders set bold targets to
avert a global disaster.
Prior to launch there were conflicting ways to report carbon, and according to the RICS Global Construction Monitor, 40% of industry didn’t feel that accurate carbon measurement was understood. The coalition – through ICMS3 – has introduced a simple, easy to use method that will allow the reporting of the emissions created – which in the near future will allow developers to alter their proposals (either by selecting more sustainable materials or adopting construction practices) to drive down the impact to the climate.
As well as reporting on
‘embodied carbon’, ICMS3 also allows the lifecycle, cost and carbon impacts of
a building or infrastructure to be taken into account long after construction
is complete.
Also,
with a push to retrofit and reuse old buildings, rather than knocking them
down, the Standard provides developers with data and information which could
allow them to make informed considerations about the value of retrofitting.
As a global professional body, RICS are set to embed the new coalition standards into their standards and guidance for all members who operate in the construction sector. As such, RICS are planning to publish an updated whole life carbon assessment standard in 2022, which will align to ICMS3.

Alan Muse, Head of Construction Standards at the Royal Institution of Chartered Surveyors, said: “De-carbonisation of construction is now essential to meet the goals of COP 26. Critically, to achieve this, we need globally standardized reporting systems – unless we measure it, we cannot manage it.
“The use of ICMS 3 will
benefit all construction stakeholders who wish to reduce carbon for a
combination of compliance, market and societal reasons and also drive
innovation in terms of alternative designs and solutions.”
Justin Sullivan, Chair of the ICMS Coalition and Construction Industry Council, added: “The ICMS journey has been a beacon of how collaboration works. We have 49 international public benefit bodies that have together created world class standards in the construction and infrastructure sectors.

“When it comes to
international standards for costs, life cycle and carbon in construction we are
the only show in town, true pioneers.
“The timing of the launch
of ICMS3, THE standard for carbon in construction could not be better with the
world stage digesting and implementing the outcomes of COP26. Onwards and
upwards.

Today’s publication follows a consultation that took place earlier this year and sought the views from all sides of the construction industry.
