Manage embodied and operational carbon to meet Net Zero targets

Nearly two thousand municipalities have declared a Climate Emergency, and over one thousand large corporations have committed to Science-Based TargetsDifferentiating with climate action is not enough to lead. The leading organisations develop and implement Net Zero Carbon and Carbon Neutrality* practises in their projects.

Net Zero targets require us to take control of both operational and embodied carbon – throughout the life-cycle of our buildings.


Free tools for optimising operational and embodied carbon

One Click LCA partners with IES-VE to provide MEP, energy designers and architects free tools to measure and compare both the operational and embodied carbon impact of their projects during the early design stages.

IES-VE Gaia:  Early-stage design

  • Climate/Bio-Climatic Interrogation
  • Building Metrics/Materials Review
  • Natural Resources/Water Analysis
  • Energy/Carbon Simulation
  • Heating/Cooling Loads Calculation
  • Low/Zero-Carbon Technologies

Free trial period: 1st Oct – 31st Dec 2021.

Net Zero Carbon Tool

  • Calculate embodied carbon of your projects with the One Click LCA Net Zero Carbon Tool.
  • Import energy models from VE Gaia to get the operational carbon data.
  • Quantify all carbon-emitting (embodied + operating) and carbon-reducing options and achieve Net-Zero.

Free trial period: 1st Oct – 31st Dec 2021

Frequently Asked Questions

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.

The IES Gaia integration also provides access to the Net Zero Carbon add-on 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.

Construction LCA & Embodied Carbon Experts’ Outlook 2021

This report, based on a survey of 165 construction LCA experts across Europe, North America, discusses the outlook on embodied carbon and LCA in construction, or greenhouse gas emissions from construction materials over their whole life-cycle in construction works, a key area of intervention to meeting climate objectives.

For governments, cities, and policy makers

Policy framework

City policy framework for dramatically reducing embodied carbon

This framework provides guidance for cities considering policies that can deliver the highest impact within their geopolitical contexts and regulatory systems. Over 50 existing policies from leading cities have been evaluated, categorized, and scored according to their potential, cost efficiency, ease of implementation, and enforceability.


Embodied Carbon Benchmarks for European Buildings

The Embodied Carbon Benchmarks for European buildings research provides benchmark data from 3737 European buildings. It aims to support regulators in policy creation and private organisations in establishing corporate policies that require pan-European information.
