Energy v1.1

• Climatiq has released a minor update to the energy feature, which is now available. The update includes some improvements to coverage, usage of the latest emissions factors from national sources, and updates to methodology.
• Coverage for the electricity core dataset rises by 20 countries to 80 countries
• Coverage for heat and steam now includes Austria
• This is a non-breaking change from v1, and so you can just update the URL you use and immediately start using it. This is released as a separate version, so that you have control over when to adopt the changes which can result in material changes to your estimations.
• This is the changelog & upgrade guide for v1.1. See our API versioning guide for how API versioning works at Climatiq.
• This document lists the changes between v1 and v1.1.

Changes between v1 and v1.1

Backported non-breaking feature additions

A notice production_mix_used_for_supplier_mix has been added in case a production mix emission factor has been used to estimate electricity emissions due to the absence of a supplier mix factor. This does not affect any IEA data, only national data for Canada and its provinces and European data from AIB. Production mix factors do not take into account cross border trade, and can lead to variations of emissions attribution between countries.

We have added new data points to source trail for non emission factor source data. This gives more transparency into the assumptions that the estimation is based on. The data points which are now reported:

• "Combustion efficiency of fuels for electricity & heat generation"
• "Default well-to-tank ratio of electricity generation emissions"
• "Default transmission & distribution loss factor for direct electricity"
• "Default transmission & distribution loss factor for grid electricity" (new methodology - see below)

Methodological updates

The emission factors used have been updated from data version 20 to data version 23. This includes a number of changes, including:

New data sources for electricity generation emissions:

• Covenant of Mayors provides location-based electricity generation emission factors for many countries, these factors are now used wherever we don't have factors from official national sources or from AIB
• Government of India
• UBA Germany
• UBA Austria
• CO2 Emissiefactoren Netherlands

Updates for electricity generation emissions factors:

• New data for 2023 from Government of Canada
• New data for 2023 from EPA in US

Updates for market emission factors:

• New residual mix electricity data from Green-e in US for 2022
• New residual mix electricity data Electricity Info in GB for 2024
• New supplier-specific electricity data from Electricity Info in GB for 2024

New heat and steam coverage for Austria using data from UBA

Updates for fuel factors:

• New data source CO2 Emissiefactoren for NL
• Updates for EPA (US), UBA Germany (DE) and UBA Austria (AT)

Transmission and Distribution Losses

We have updated our methodology for estimating transmission and distribution losses when using the core dataset, especially in cases where national sources do not provide this data. Previously, we used data from DEFRA (BEIS), which is no longer updated; we have now replaced it with default fallback proportions based on our team's research. In this case you will see the following source trail data point:
