Select a pathway

Every pathway is defined by country, property type, and climate zone. Change the selectors to load a different pathway; the chart and download file update in place.

Emissions scope

Use “All-GHG” if you have refrigerant/F-gas data. Otherwise, “Energy-related CO₂” covers operational energy emissions only.

Supporting datasets

Datasets that power an assessment

Pathways are the benchmark — explored above. These three supporting datasets supply the emission factors, sub-national lookups, and optional climate-adjusted projections that the calculation steps draw on.

Emission Factors

Per-carrier emission factors with actuals for historical years and country-level projections through 2050. Grid electricity factors decline annually; combustion factors for gas, oil, biomass, and other fuels are held constant. Essential for calculation steps A3 and A6.

Emission factors in the latest version are refreshed whenever the underlying sources CRREM relies on publish new values.

HDD/CDD Lookup (EU) optional

Heating-degree-day and cooling-degree-day projections by European postal code, for 2015 and 2024 baselines, under SSP5-8.5 and SSP2-4.5 climate scenarios. Supports the optional climate-adjusted EUI projection in Technical Blueprint step 6.1a.

This is an illustrative dataset extracted from the CRREM legacy tool. Newer scenarios are already available and will replace this file in a later release.
