Data Version 1.1
This is the data version 1.1. The highest major version is 1, and the highest minor version is 1.
To use the major version, you can use

This data version was released May 10th 2023.
Data version 1.1 is Climatiq's first data release since introducing data versioning (in API version beta4), so it contains a large number of changes which we had previously held off from making as they could have broken our client's applications.
- Circular Ecology ICE Dataset for embodied carbon in common building construction materials (opens in a new tab).
- EPA spend-based dataset version 1.1.1
- Added UK domestic electricity supplier (opens in a new tab) emission factors for year 2021. Last month, we introduced emission factors for the most recent year reported by each supplier, with some providing data for 2022 and others for 2021. To ensure a more thorough and consistent overview, we have now integrated all relevant data for the year 2021.
This Data Release comes with a large amount of modifications that you might need to take into account. The larger changes will be listed first, and changes that affect few emission factors at the end.
Minor changes such as name or description changes are not listed. Find a link at the end of this document to a structured table listing all changes.
Electricity emission factors have been updated to properly list what sort of grid they correspond to.
To make electricity emission factors' activity IDs consistent and make them easier to be used for scope 2 reporting, we have come up with a new activity ID structure as described below:
Emission factors that had the structure
electricity-energy_source_*, now generally have the structure
electricity-supply_grid-source_*, and the source can be either
supplier_mix, or any specific generation source if known e.g.
Examples are the following:
as the grid mix corresponds to supplier mix unless specified by the source.
Emission factors with the following activity IDs have unit changed from km to passenger-km:
The source (GHG Protocol) does not clarify if the kgCO2e value is calculated using either IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) methodologies. Therefore, we added the
notable_methodological_variance quality flag.
All EFs from GHG Protocol Tool got a new flag
notable_methodological_variance, because the dataset was deprecated and removed from their website. We might remove it in the further versions of the database.
Emission factors that started with
fuel_type, such as
fuel_type_wood_and_wood_residuals-fuel_use_stationary_combustion now correctly start with
fuel-type (dash instead of underscore)
All BEIS 2021 flight EFs (freight and travel) got new sub-id in the activity ID:
Many emission factors that started with
heat-and-steam-, such as
heat-and-steam-type_plant_medium_natural_gas have been renamed to properly start with
heat_and_steam-, such as the previous one being renamed to
The heat and steam emission factor from the GHG protocol has further changed activity ID from
Many emission factors that previously started with
wtt in the first part of the activity ID, such as:
Now we have omitted the
wtt part. The
wtt meaning well-to-tank is now reflected in the lca_activity of the emission factors instead.
Several emission factors regarding Azure cloud regions for India have changed activity IDs, such as:
We recommend you use the dedicated cloud endpoints instead of these emission factors directly.
All ids starting from
metals_primary- turned into just
Activity_ids for vehicle EFs from EXIOBASE were corrected to match the usual Climatiq’s structure for this category.
All activity IDs for water distribution services have changed, to reflect new activity ID structure:
Activity IDs for stone materials changed from
mined_materials-type_stone Because of re-categorization
Other Materials →
To correct a typo we have changed activity ID:
Name change: "Intert/metal waste for treatment: incineration" → "Inert/metal waste for treatment: incineration"
To comply with the activity ID structure for Arable Framing category we have corrected activity ID EFs for paddy rice in the following way:
- EPA spend-based data version 1.0 and 1.1 were removed.
