Details

Based on current grid intensity in the North East from the public carbon intensity API. The number of flights is based on 670.9 kg / pass trip from the ICAO calculator. The number of train trips is based on a distance of 422 km and the DEFRA conversion factor of 0.052 kg / pass km. The number of paperbacks is based on 2.71 kg / book produced in North America (Wells+12). The number of deliveries is based on 120 drops per 50-mile round trip and 0.27 kg / km for a delivery van (CILT UK, 2009). Cups of coffee is based on 21 g / cup. Power usage is from the COSMA presentations.
