The software enables material manufacturing localization by default. The default version remains version 1 in order to avoid confusion in projects were targets were established using this version. Users can review the versions, switch from one to another and disable it from the project parameters and all results will be directly recalculated for the whole project.
Material manufacturing localization is enabled on a project level, by using a target country. Still, Expert license users can disable/enable it, or switch it from a target country to another for each individual material depending on where they are sourced. This is explained here: Adjusting compensations settings
Material manufacturing localization version 2 increases accuracy regarding the amount of electricity used in the manufacturing of different material subtypes. Also, the new version is better calibrated against extreme scenarios related to compensation among countries with very different electricity mixes. Finally, version 2 is in a beta version and will be fine-tuned.
How does it affect my existing projects?
Your existing projects are not affected unless you change the project parameters and save them. Every time you change these parameters, all results in the project are recalculated.
When a baseline/reference is set, the assessments and the baseline/reference shall be calculated using the same compensation method.
Which version should I select in my ongoing or new projects?
When there is a baseline building calculated and targets were set accordingly, it is strongly suggested to use the same settings as the baseline.
For ongoing projects, in cases where the analysis and reporting are in an advanced stage, it is suggested to complete the project with the same settings.
While version 2 is significantly improved, it is still in a beta version and being fined tuned and switching to it is recommended only for projects that would not have negative impacts from slight adjustments to results resulting from such configuration changes.
Which countries are more sensitive to compensation?
Compensation is influenced by the energy mix of the different countries. Consequently, the most sensitive countries are the ones that deviate most from the average energy mix.
What does this change mean practically?
In the updated version, the values for required manufacturing electricity are reduced for most product categories, except steel-based products where electricity consumption related to the manufacturing of steel semi-finishes is now also accounted for. Furthermore, the new version is deactivated for product categories that include high diversity of products, such as etics, concrete admixtures, “other insulation” and furniture. Practically, this means that manufacturing localization version 2 is expected to lead typically to smaller adjustments between countries in comparison to version 1.
Most affected materials are the ones whose impact is most influenced by electricity consumption, and at the same time, their corresponding required electricity value in the model has changed significantly. Most noticeable differences for common construction materials are related to wood, insulation and glass products.
What sources were used for the electricity values?
Most commonly data from Ecoinvent 3.6 were selected as references, while in other cases, selected values are based on public industry-wide studies and market average EPDs. Overall, selected values were tested for plausibility, based on an extensive comparison with generic and manufacturer-specific data from multiple markets.
