One Click LCA, the leading sustainability software platform, releases critical updates to meet new RICS whole-life carbon 2nd edition requirements

The end-to-end sustainability software platform now enables users to align with the revised RICS whole-life carbon assessment standard, which will take effect on July 1st, 2024. As a comprehensive revision of its original 2017 standard, the updated RICS standard represents a significant shift towards a more inclusive, comprehensive, and global approach to carbon measurement in the built environment, and gives the construction industry new visibility on carbon emissions from the whole life-cycle of a building, from pre-planning to full operation.


London, United Kingdom (27th June, 2024)  One Click LCA, the world-leading construction software for improving sustainability in construction, today announces critical software updates that will enable sustainability professionals across the construction industry to align with the new RICS whole-life carbon assessment professional standard, 2nd edition.

As a Greater London Authority and BREEAM-approved tool for nationally recognised assessment methodologies, this One Click LCA software and compliance update is a critical modification that supports all construction professionals working with the RICS standard and reinforces One Click LCA’s position as the world-leading tool for life-cycle assessments.  

The new RICS standard is an important step in tackling carbon emissions from buildings. According to the World Green Building Council, International Energy Agency, and One Click LCA data, 57% of global carbon emissions are caused by buildings and infrastructure. Furthermore, embodied carbon will be responsible for half of the entire carbon footprint of new construction between now and 2050, meaning the construction industry needs to adopt means to reduce carbon life-cycle emissions.

To support users working with the revised RICS standard, One Click LCA has implemented significant updates to the existing tool, including: 

  • Decarbonised and non-decarbonised results for materials and operational impacts. 
  • Default scenarios, according to RICS, for life cycle stages A5, B2, B3, and end-of-life. 
  • RICS categories updated to match the NRM3. 
  • New input page for pre-construction inputs affecting A0 and A5.1 stages. 
  • New transportation profiles account for a proportion of return trip impacts. 
  • B2 and B3 scenarios enabled. 
  • Added worker transportation inputs. 
  • Scenarios added for Pre-construction demolition (A5.1), Construction site works (A5.2), Demolition/deconstruction stage (C1). 
  • New sub-categories for various LCA stages (A5, B1, B7) to align with the reporting requirements. 
  • Contingency and uncertainty factors. 
  • Automated report generation. 

The updated RICS standard addresses the immediate needs of the industry and positions RICS as a leading framework for achieving sustainable and net-zero goals across the built and natural environments. The 2nd edition extends the existing RICS WLCA standard to cover all buildings and infrastructure throughout the built environment life cycle. This gives visibility to embodied carbon, operational carbon, and user carbon — which are vital to carbon calculations and a unique feature of the RICS standard. 

“We help architects, developers, and other players in the construction value chain decarbonise their projects. As the software of choice for construction professionals, we needed to ensure we enabled the industry to align easily with the new RICS standard coming into effect in July 2024. Our existing users will have immediate access to the new functionality, and those considering One Click LCA for their construction projects can be confident that we work closely with the industry standard-setters to maintain our position as the world leader in construction and manufacturing decarbonisation,” says Johanna Jarvinen, New Products Lead at One Click LCA.
