Ember NECP data methodology

This document outlines the data methodology used by Ember to process National Energy and Climate Plans (NECPs) and historic energy and emissions data. It details the preference for 'with additional measures' (WAM) projections, the conversion of energy units, the mapping of UNFCCC and Eurostat categories to specific sectors, and the sources used for historic generation and greenhouse gas emissions.

• Ember prioritizes electricity data from NECP projections that include 'with additional measures' (WAM), which encompass both implemented policies and options under discussion with a realistic chance of adoption. If WAM projections are unavailable, 'with existing measures' (WEM) projections are used instead.
• To ensure consistency in solar capacity reporting, Ember attempts to present all figures in direct current (DC, gross output), noting that AC capacity differs from DC by a factor of 1.25. However, the document acknowledges that not all data can be guaranteed as DC due to a lack of transparency in national reporting.
• Energy values reported in million tonnes of oil equivalent (mtoe) are converted to terawatt hours (TWh) using a conversion factor where 1 mtoe equals 11.63 TWh.
• Historic greenhouse gas emissions data is sourced from the EEA's reports to the UNFCCC and the EU Greenhouse Gas Monitoring Mechanism, specifically using the pollutant 'All greenhouse gases (mtCO2eq)' for sectors 1-6. This scope includes LULUCF but excludes international aviation and navigation, aligning with the EU's Fit for 55 target of a 55% reduction in net emissions by 2030 compared to 1990 levels.
• Historic final energy demand data is extracted from the Eurostat database's 'Complete energy balances' (NRG_BAL_C), specifically the 'Final consumption - energy use' (FC_E) category, which is then mapped to specific fuel types (Coal, Oil, Gas, Electricity, Renewables, Other non-renewable, and Heat) and sectors (Industry, Transport, Buildings, and Other).
