Change Log
7/03/2026 – all eTool Default datasets (minor software release v5.39.0)
This minor release features the following update:
- Updated Default LCI Material Factors
Construction Waste and Recycled Content factors for eTool Default LCI materials now align with with RICS WLCA PS 2E assumptions. Existing projects and custom templates are not affected, and [edited] all default public templates have also been updated as of 14/03/2026. More details are available in the support post: Default Construction Waste Factors & Recycled Content in eTool.
11/10/2025 – all datasets V20.2 (minor release)
This minor release features the following updates:
- Correction for Aluminium
Correction made in the Ecoinvent data where aluminium shallow regionalisation was occurring at the wrong level in the supply chain in V20.1 leading to far higher increases from V19 than should be. You’ll see aluminium GWP impacts drop around 6% (AU), 40-55% (UK, NZ & EU) and 15-20% (Global) from V20.1 impacts. - Correction for Copper
The copper mix in V20.2 has been remodelled to exclude those made directly from scrap across all regions. This removes false regionalisation of copper in low impact grid regions such as UK or Europe which were giving misleadingly low values in v19. You’ll see about 20-30% GWP increase from V20.1 impacts across all regions. - Correction for Plasterboard (AU)
Corrections made for the AU dataset which had a small error in the underlying AusLCI process with the amortisation of infrastructure which caused virgin plasterboard to have too much increase in impacts compared to V19. GWP impacts for 100% primary gypsum plasterboard has decreased by approximately 47% from V20.1 impacts. - Adjustment for Timber (Unspecified Supply)
In V20.1, there was no impact differentiation between ‘Unspecified Supply’ and ‘Sustainably Sourced’ timbers where the full benefit of carbon sequestration (biogenic carbon) have been accounted for as per the EcoInvent/AusLCI data. In V20.2, carbon sequestration benefits (GWP-biogenic) have not been applied for unspecified supplies of timber to represent worse case scenario of the timber being sourced from old-growth/non-responsibly managed forests which are considered ‘non-renewable’.
- Correction for MEM indicators
MEM indicator impacts for several recyclable materials and the disposal of a few end-of-life methods were incorrect which was causing the MEM results to be wrongly calculated. These have been reviewed and updated for metals, glass & plastics materials.
25/09/2025 – All Datasets V20.1
- Correction to default densities for 0%, 5% and 20% RAP asphalt hot mixes
These three materials had 2000 as the default density which was causing the impacts to be inconsistent with the other mixes. The default density has been updated from 2000 to 2300. This update will only affect new designs created from here on. Existing certified designs won’t be affected. To update existing uncertified designs with the new density, you will need to manually edit the material density in your design (Updated 30/10/2025: Existing asphalt templates in the library containing these materials have been updated to the new density! However, if you notice any public templates that we may have missed, please raise a support request so that we can get it updated for you.)
31/05/2025 – All Datasets V20.1 (minor release)
- Correction to Refrigerant leakage GWP values
Refrigerant leakage GWP values have been updated to reflect the latest IPCC AR6 guidelines, replacing the previous AR5 values.
25/01/2025 – All Datasets V20.0
- Correction to Mass Indicators
Mass indicators have been corrected to ensure that Total Mass indicator is now equal to Mv + Mrec + Mren + Mrenrec + Mreu + Mrenreu. Material Efficiency has been recalculated based on Mv + 0.7*Mrec + 0.35Mren + 0.245Mrenrec + 0.1Mreu + 0.35Mrenreu.
Where:- Mv = Mass of non-renewable primary material (t)
- Mrec = Mass of non-renewable secondary (recycled) materials (t)
- Mren = Mass of renewable primary material (t)
- Mrenrec = Mass of renewable secondary (recycled) material (t)
- Mreu = Mass of reused non-renewable materials (t)
- Mrenreu = Mass of reused renewable materials (t)
- Correction to 1 Cement: 4 Sand
1 Cement: 4 Sand was incorrectly being categorised as 1 Lime: 3 Sand binder, resulting in incorrect results. The previous mapping in version 19 resulted in a higher impact due to an incorrect cement ratio. The new mapping in version 20 accurately reflects the lower cement ratio, resulting in a lower impact for 1 Cement: 4 Sand compared to lime mortar (1 Lime: 3 Sand).
5/11/2024 – United Kingdom LCI – V20.0
- Correction to GWP Polarity
New dataset was incorrectly reporting GWP-T, GWP-F, GWP-B and GWP-LULUC as positive numbers instead of negative numbers as required by our algorithms.
2/11/2024 – All Datasets V20.0
- Correction to Global Warming Potential – Biogenic
An outdated characterisation methodology had been used to calculate GWP-B, resulting in a misalignment with GWP-T. GWP-B has been corrected to ensure that GWP-T is now equal to GWP-F + GWP-B + GWP-LULUC, as expected. - Correction to intensity of closed-loop recycling data
Corrections were made to the intensity values for closed-loop recycling of specific materials where the data was previously incomplete. This adjustment affected all database materials with closed-loop recycling in eTool, bringing more accurate results and improving the overall reliability of the impact data. As a result, a slight decrease in impacts for A1-A3 was anticipated, which aligns with the changes observed in your design. -
Added new material
Bentonite has been added to the database.
20/07/2024 – All Datasets V20.0
- New Version of ecoinvent Dataset
All v20 Datasets are now based on ecoinvent v3.10. This represents a jump in the base data from eTool V19, which was based on ecoinvent v3.3. As we can’t identify all changes in this data, please see the release information for ecoinvent versions below. - Improved Regionalisation
Regionalisation has been refined to better account for globalisation of markets. This will be undertaken for the top level processes which contribute a majority of the impact (eg. cement is regionalized in concrete, ethylene is regionalised in polyethylene). Up stream from this point the regionalisation in the ecoinvent supply processes but default back global averages where regional processes are unavailable.
This includes changes to:- Grids
- Natural gas and oil inputs
- Water extractions and releases into the environment.
- Compliant with EF3.0
V20 Dataset is compliance to data and methods outlined in the Environmental Footprint database v3.0 - New disposal options for incineration of petroleum/hydrocarbon-based materials.
- Improved consistency within product categories
- Updates to some fuels and energy sources
- Impact Increases
- Increase in Diesel Impacts from v19
Scope 3 emissions for diesel have increased substantially (approx. double) from the previous version of the ecoinvent dataset. This comes from more accurate accounting of fugitive emissions for crude oil production. Results of this change will be apparent in:Stage Module Product Stage Raw Materials Transport (A2) Construction Stage Transport of Equipment and Materials (A4)
Transport Losses (A4)
Construction & Installation (A5)End of Life Transport of Waste Offsite (C2) - Increase in GWP-B and GWP-LULUC
GWP-B and GWP-LULUC characterisation models have been improved, resulting in moderate increases in GWP-B and more significant increases in GWP-LULUC. - Increase to Net Use of Freshwater (FW)
Net use of FW has increased by about 10x for materials due to improved characterisation models. - Increase to Abiotic Depletion Potential – Elements (ADPE) for plastics and metals
ADPE for plastics and metals has increased, impacting GS Buildings calculations. - NEW! Increases in Window Assembly Impacts (note added 21/08/2025)
More accurate window assembly impact calculations have been used, resulting in significant increases for aluminium, hybrid and PVC framed windows across all regions. Please refer to this support post for the assumptions used for window calculations – Window Assumptions V20 - NEW! Increases in Some Steel Products (note added 21/08/2025)
For UK steel, in V19 models for 89% virgin low alloyed steel (pipe and hot extrusion) were linked to the wrong steel manufacturing technology (mix included electric arc furnace), which lead to large increases in V20 when they are correctly linked to a basic oxygen furnace processes.
-
NEW! Increases in Aluminium (note added 21/08/2025)
For UK & EU, V19 had assumed alumina (the precursor to aluminium) as being produced in the same region as the aluminium – giving a lower total GHG value. In V20, alumina is coming from the world market, which is dominated by China, Middle East etc which is more accurate (and higher impact) local alumina production in regions such as the UK is non-existent and in EU is insufficient to cover overall aluminium production. For NZ, V19 assumed that 100% of electricity used in aluminium production was sourced from hydro power, which gave an extremely low footprint. This assumption had no auditable evidence supporting it, therefore in V20, the electricity allocation for NZ aluminium production was updated to the average NZ grid which aligns more with LCA best practices until better support evidence can be produced.
- Increase in Diesel Impacts from v19
- Impact Decreases
- Decrease in Ozone Depletion Potential (ODP)
Significant decreases in ODP for materials and disposals generally. - NEW! Decrease in Some Steel Products (note added 21/08/2025)
For Australian steel processes, some reductions have occurred such as hot impact extrusion (steel, hot extrusion and steel accessories) which require significant electricity inputs, due to lower grid impacts. - NEW! Decrease in Plasterboard Impacts (note added 21/08/2025)
There was an error in the regionalisation switch leading to double counting of multiple regions’ impacts in the one process, which was affecting all regions. In V19, heat used in manufacturing plasterboard was listed as a mix of almost entirely coal. In V20 based on European regionalisation, the mix is actually 2.5% biomass, 2.55% heat from fuel oil and the remainder is heat from municipal solid waste (MSW) incineration. The net effect is about a 10 fold reduction in impact for this heat. In future, for regions with less waste to energy, this model might need refining, however shifting from coal to natural gas has led to this significant improvement.
- Decrease in Ozone Depletion Potential (ODP)
