CARBON STRATEGY TOOL
Translate your projects’ LCA results into GHG reporting data
With One Click LCA Carbon Strategy tool, you can reliably translate your construction projects’ life cycle assessment results into GHG reporting data.
Bridge the gap between LCA data and GHG reporting
For companies involved in real estate and construction, high-quality data is likely to be available in the form of project life-cycle assessments (LCAs). However, until now, it has been challenging to translate project-specific LCA data to GHG Protocol scopes and categories.
Use your existing project LCA data
Project LCA data is the highest quality GHG data available. Import your LCA results into the tool for accurate GHG reporting.
Select the activities you control
Who is it for?
The tool can be used by architects, engineers and construction companies for sharing LCA data that their real estate, investor or developer clients can use in their carbon reporting.
Real estate investors, owners, developers
Request project LCA results or provide project teams with One Click LCA Building LCA software. Import the LCA results into your GHG Reporting.

How LCA results differ from GHG Protocol reporting
Who controls the activity that causes the emissions
The GHG Protocol scopes are:
- Scope 1: direct emissions released as a result of company activities.
- Scope 2: indirect emissions from purchased energy.
- Scope 3: all other indirect emissions, that are not included in scope 2.
When emissions are reported
Where future emissions are locked-in to sold products, they are accounted for in Scope 3 emissions in specific categories.
Construction LCA results are grouped into life-cycle stages ranging from A to D, covering life-cycle phases from construction to use phase to end of life and impacts beyond the system boundary.
Which emissions are reported
GHG Protocol Scopes 1 and 2 only cover direct combustion emissions from the seven Kyoto protocol gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PCFs), sulphur hexafluoride (SF6) and nitrogen trifluoride (NF3).
Construction LCAs, however, always use life-cycle based emission factors and consider all greenhouse gases.

Frequently Asked Questions
How do I get access to the Carbon Strategy tool?
The One Click LCA Carbon Strategy Tool is available as part of the One Click LCA Carbon Strategy Pack. This pack also includes a range of tools to help deliver climate strategy goals, including Carbon Designer, Net Zero Tool, Building Circularity and Life-Cycle Costing, as well as tailored onboarding.
It is compatible with all One Click LCA Building LCA tools. However, there is only limited compatibility with the RE2020 and Energie Carbone tools. When using these tools, it is only building materials that are directly transposed to GHG Protocol reporting.
Why do I need to use LCA data for GHG reporting?
What emission sources can be reported?
- You can report emission sources according to ISO 14069, the GHG protocol, and CDP standard categories. These include:
- Scope 1: Direct emissions from stationary and mobile combustion sources, fugitive emissions, processes and biomass emissions
- Scope 2: Indirect emissions from electricity, heating and cooling consumption
- Scope 3: Purchased goods and services, capital goods, waste, business travel and commuting, investments, freight, use and end-of-life of sold products, downstream leasing and franchises.
What emissions data is included?
One Click LCA integrates emissions factors for energy (IEA, local energy agencies and providers, and One Click LCA’s own datasets), goods and services (DEFRA, WWF, Base Carbone), extended capital goods from the Carbon Heroes Benchmark Program, and additional datasets.
You can also add your private emission factor data or ask us to add compliant data for your sector if anything is missing.
Not all data sources break down data based on gases, and in such cases, the assessment considers all greenhouse gases. The assessment considers at a minimum all Kyoto Protocol gases (CO2, CH4, N2O, HFCs, PFCs, SF6 and NF3) on a 100-year timeframe.
How does GHG reporting differ from life-cycle assessment?
The standard emission factors basis is different: The GHG Protocol scopes 1 and 2 only take into account direct (combustion) emissions, whereas LCAs always use life-cycle based emission factors and consider all GHG gases.
The GHG Protocol reports emissions based on the period in which they arose, often a calendar year or a quarter. Where future emissions are locked-in by sold products, they are accounted for in Scope 3 emissions in specific categories. An LCA looks at the entire life-cycle of a product or service: from first manufacture to end-of-life, as well as impacts beyond the system boundary. LCA results are grouped into life-cycle modules A to D.
