Electricity Emissions Factors¶
aPriori leverages electricity carbon emission factors from Ecoinvent, a comprehensive global database for Life Cycle Inventory (LCI) data.
In their latest release (v3.10), Ecoinvent has updated the electricity market mixes to reflect 2020 data. In certain specific cases (Brazil, China, USA, Canada, and Switzerland), the electricity mixes are updated to reflect the situation in 2021. India was updated to represent the fiscal year of April 2019-March 2020.
The table below shows the updated electricity carbon factors (v3.10) and the percentage changes compared to the previous release, which used Ecoinvent v3.9.1.

Material Emissions Factors¶
aPriori primarily leverages material carbon emission factors from Ecoinvent, a comprehensive global database for Life Cycle Inventory (LCI) data.
In their latest release (v3.10), Ecoinvent has made significant updates to plastic materials. The update, which was performed in collaboration with PlasticsEurope, aimed to improve the database content for the most essential raw materials used in the production of a wide range of chemicals and plastics. This sees a significant change in several plastic materials used in the aPriori materials database, with the largest increase being approximately 60%.
In addition to this, Ecoinvent has added expanded plastics coverage, now including the material Acrylic (PMMA). aPriori is now leveraging this dataset in place of a secondary data source, resulting in an increase of approximately 148%.
The table below shows the updated material carbon factors (v3.10) and the percentage changes compared to the previous release, which used Ecoinvent v3.9.1 (this table includes all changes > +/-3%).

Consumable Emission Factors¶
aPriori leverages consumable carbon emission factors from Ecoinvent, a comprehensive global database for Life Cycle Inventory (LCI) data.
The Emissions factor for heat production from natural gas for industrial use cases has increased 1.80% in various melting processes. However, the emissions factor for natural gas in Bar & Tube Fabrication has been updated to be consistent with the dataset used for the melting processes and no longer uses a dataset for liquified petroleum gas. As a result, the emissions factor for natural gas in Bar & Tube Fabrication has decreased by 63%.
Several consumable materials have changed dataset from a market data set to the production dataset, resulting in some more significant changes. This dataset mapping has been updated to ensure consistency across all data taken from Ecoinvent. Affected consumables include Bentonite, Cereal, Furan, and Kaolinite.
The table below shows the updated carbon factors (v3.10) and the percentage changes compared to the previous release, which used Ecoinvent v3.9.1:
