Klimatkalkylatorn: Metoddokument

This methodology document describes the data, calculations, and assumptions used in 'Klimatkalkylatorn', a climate footprint calculator developed by the Stockholm Environment Institute (SEI) and WWF Sweden to help the public understand the environmental impact of their lifestyles.

• The calculator divides household consumption into four main categories: Housing (Bostaden), Food (Biffen), Transport (Bilen), and Goods/Activities (Butiken), while also adding a fixed impact for 'Society' (Samhället) to account for public services like healthcare and infrastructure.
• For housing energy calculations, the tool uses specific emission factors: District heating is 0.0886 kg CO2e/kWh, Electricity (Nordic mix) is 0.0973 kg CO2e/kWh, Fuel oil is 0.288 kg CO2e/kWh, Pellets are 0.01872 kg CO2e/kWh, and Corn-based biogas is 0.0792 kg CO2e/kWh.
• To avoid penalizing users for the higher cost of organic food, the tool applies a 27% reduction in the impact of purchased food if the user reports 100% organic consumption, based on PRO's price surveys showing organic food is on average 27% more expensive.
• Transport calculations include both direct emissions from fuel and indirect emissions from vehicle production and maintenance. Due to a lack of detailed Swedish official statistics at the time of development, the tool utilized UK emission data from Defra for personal vehicles and flights, applying a Radiative Forcing Index (RFI) factor of 1.9 for high-altitude flight impacts.
• The 'Society' category, representing public administration and services, is estimated at 2.16 tonnes of CO2e per person, distributed equally among all users.
• The tool compares individual results against three benchmarks: the average Swede (10.7 tonnes CO2e per person, based on 2015 data from Naturvårdsverket), the global average (6.4 tonnes CO2e per person, based on 2014 data from Climate Action Tracker), and a 2020 target of 7 tonnes CO2e per person set by WWF.
