International Cost Management Standard (ICMS)

ICMS 3

ICMS provides a high-level structure and format for classifying, defining, measuring, recording, analysing and presenting life cycle costs and carbon emissions associated with construction projects and constructed assets.

ICMS began with the first two versions of the standard covering cost for construction and the whole life cycle of infrastructure assets: With the built environment responsible for around 40% of the global carbon emissions, it is crucial that leaders have clear comparable data to achieve carbon and cost targets. The ICMS Coalition of 49 globally-prominent organisations has developed ICMS 3 – a world first for cost and carbon management in infrastructure.

ICMS 3 will contribute positively to efforts to decarbonise the construction sector in the most cost-effective way. Through ICMS 3, professionals will for the first time be empowered to deliver a globally consistent method for carbon life cycle reporting across construction projects, from buildings and bridges to ports and offshore structures.
