Optimise for Net Zero embodied and operational carbon
Special resources for: MEP & Energy Designers | Architects
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 Targets. Differentiating 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?
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 support@oneclicklca.com to request access.
What features are included?
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?
Are you offering other free tools and resources during COP26?
What is COP26 anyway?
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.

Report
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.
