It’s time to focus on the embodied carbon of structures

Structural elements are responsible for around 70% of a building’s total embodied carbon, making cutting the carbon of structural design critical in the race to zero. However, calculating embodied carbon is a relatively new concept for many structural experts – whether engineers, fabricators, detailers or contractors and builders.

Managing carbon performance is becoming as important as managing cost.

Until recently, only a few contracts or tenders have specified embodied carbon limits, but that is about to change. Government bodies and cities across Europe and North America are starting to introduce regulations that mandate embodied (or whole life) carbon declaration and limits for buildings and infrastructure projects. See list of current and coming regulations here.

Turn constructible BIM data into accurate embodied carbon results

Combining constructible data from Trimble’s Tekla software with One Click LCA and its extensive Environmental Product Declarations (EPD) database allows the carbon emissions of every nut, bolt or rebar in a design to be calculated.

Who can access the free One Click LCA tool?

Anyone can access the free One Click LCA tool for the duration of this offer. However, using the integrations works differently depending upon whether you are a new or existing One Click LCA user. 

For new One Click LCA users: Using the integrations with Trimble, IES or Rhino will require the respective licenses. Access to the free One Click LCA tool is available until the end of 2021.

For existing One Click LCA users: If you have a Business plan or higher, you have access to these integrations, even beyond the end of this offer period. If you have a Starter plan, please write to to request access.

What features are included?

The One Click LCA free tool gives users access to all of the features available under a standard One Click LCA Building tool Business license. The full feature list can be seen here.

For our Trimble integration, we also have country-specific tools that match the requirements of the relevant country:

FINLAND: Building carbon footprint (YM) tool

SWEDEN: Klimatdeklaration

FRANCE: RE2020 Carbon Only tool

NORWAY: NS3720, Business, no Carbon Designer

Rest of Europe: Level(s) carbon tool

How long will I have access to the free tool?
Access to the free One Click LCA tool is available until the end of 2021. After this time, access will be available to anyone who buys a commercial One Click LCA license.
Are you offering other free tools and resources during COP26?

Yes, we want to use the opportunity of COP26 to encourage the construction sector to accelerate decarbonisation. To this end, we are providing free tools and resources for the entire construction value chain. You can see them all in the COP 26 resource center.

What is COP26 anyway?

It’s a short name for a globally important meeting: the annual UN climate change conference. The famous Paris Agreement was signed at COP21, held in Paris, in 2015.

COP stands for Conference of Parties, with the parties referring to the 197 nations and territories that have signed on to the UN Framework Convention on Climate Change.

This year’s event will be the 26th conference, hence COP26.

COP26 takes place in Glasgow, UK, in November 2021. Find out more at the official COP26 website.
