CARBON STRATEGY TOOL
Translate your projects’ LCA results into GHG reporting data
With the 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
Kenelle se on tarkoitettu?
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

Architects, designers, engineers and consultants

Construction firms
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.

GHG Reporting tool

The One Click LCA GHG Reporting tool is an organization-level tool that enables companies to calculate emissions from across the whole value chain in line with ISO 14069, GHG protocol, and CDP standard categories.
It allows you to set reduction targets, track your organisation’s progress over time, and share results with your stakeholders.
Carbon Strategy Tool

The One Click LCA Carbon Strategy tool is a project-level tool that links project-specific LCA data to GHG reporting requirements.
Architects, engineers and construction companies can use the tool to share project data that their real estate, investor or developer clients can use in their Scope 1-3 GHG reporting.

Usein kysytyt kysymykset
How do I get access to the Carbon Strategy tool?
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.
What is the difference between the Carbon Strategy tool and the GHG Reporting tool?
The Carbon Strategy Tool is a building project-based tool. Its goal is to link building LCA data to GHG reporting. The Carbon Strategy tool follows the same approach to data input as our standard building tools, but organizes the results into the different GHG scopes.
Why do I need to use LCA data for GHG reporting?
Mitä päästölähteitä voidaan raportoida?
-
- Voit raportoida päästölähteitä ISO 14069:n, GHG-protokollan ja CDP-standardin mukaisesti. Nämä ovat muun muassa seuraavat:
- Scope 1: Suorat kasvihuonekaasupäästöt
- Scope 2: Epäsuorat kasvihuonekaasupäästöt
- 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.
Mitä päästötietoja raportteihin sisältyy?
Voit myös lisätä yksityisiä päästötietoja tai pyytää meitä lisäämään vaatimustenmukaisia tietoja sektorillesi, jos jotain puuttuu.
Kaikki tietolähteet eivät kuitenkaan erittele tietoja päästöjen perusteella, jolloin arviointi ottaa huomioon kaikki kasvihuonekaasut. Arviointi ottaa huomioon vähintään kaikki Kioto-protokollan päästöt(CO2, CH4, N2O, HFCs, PFCs, SF6 ja NF3) 100 vuoden aikavälillä.
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.
