Klimatkalkylatorn: Metoddokument

The document outlines the methodology for the Klimatkalkylatorn tool, which estimates a user's climate footprint across four consumption categories: housing, food, transport, and shopping, plus a fixed societal impact. It details the use of Swedish national statistics (SCB), the GTAP input-output model for indirect emissions, and specific emission factors for energy and transport. The tool compares individual results against a Swedish average of 10.7 tonnes CO2e, a global average of 6.4 tonnes CO2e, and a 2020 target of 7 tonnes CO2e per person.

• Housing emissions are estimated based on dwelling type, age, and floor area, using specific emission factors: district heating (0.0886 kg CO2e/kWh), electricity (0.0973 kg CO2e/kWh), fuel oil (0.288 kg CO2e/kWh), pellets (0.01872 kg CO2e/kWh), and corn-based biogas (0.0792 kg CO2e/kWh).
• Food impact is calculated using SCB expenditure data and the GTAP input-output model to account for indirect emissions and the split between domestic and imported products. To avoid penalizing users for the higher cost of organic food, the tool applies a 27% reduction in impact for 100% organic consumption, based on PRO price surveys.
• Transport emissions include both direct fuel emissions and indirect emissions from vehicle production. Due to a lack of detailed Swedish official statistics at the time of development, the tool used UK Defra data for personal vehicles and flights, applying a Radiative Forcing Index (RFI) factor of 1.9 for high-altitude flight impacts.
• The tool benchmarks individual results against a Swedish average of 10.7 tonnes CO2e per person (based on 2015 data from Naturvårdsverket), a global average of 6.4 tonnes CO2e per person (based on 2014 Climate Action Tracker data), and a WWF target of 7 tonnes CO2e per person for 2020.
