The CO2 emission factors presented in Tables 1, 2, 4, and 5 are derived from a standardized methodology developed within the Federal Funding for Energy and Resource Efficiency (EEW) program.

A detailed methodology, including the derivation and application of the emission factors, is provided by the source: https://www.bafa.de/SharedDocs/Downloads/DE/Energie/eew_infoblatt_co2_faktoren_2025.html

Climatiq has extracted data from the following tables:

Table 1 provides CO2 emission factors for renewable and low-CO2 energy sources, supporting the assessment of emission reductions in energy carrier switching scenarios.

Table 2 presents standardized and binding CO2 emission factors for a broad range of energy carriers, used for calculating emissions in the energy savings concept, including both direct emissions and upstream processes. Electricity and district heating emission factors rely on model calculations or system-specific values to reflect variations in generation and supply conditions.

Table 4 classifies materials into resource categories with generic CO2 factors, enabling approximate emission estimation when specific data is unavailable.

Table 5 provides specific CO2 emission factors for individual materials, calculated using a cradle-to-gate life cycle assessment approach and applied for detailed, material-level emission accounting within the savings concept.

The methodology does not represent a full life cycle assessment, as downstream emissions and certain indirect sources may be excluded. Intended specifically for use in the EEW energy savings context rather than for general scientific applications.
