- Mass of Carbon Dioxide (CO2) emitted per kWh generated in the UK is 0.43kg. (Source: Carbon Trust)
- CO2 emissions of Renault Megane 1461cc Manual car is 120g/km
(Source: Vehicle Certification Agency www.vcacarfueldata.org.uk) - Connected load of 1 x 400W metal halide high bay fitting is 450W. High bay fittings may have a connected load as high as 480W, however low bay fittings are typically 440W to 450W and hence an average figure of 450W is chosen.
- 1 x 400W fitting running 24/7 365 days per year uses 3931.2kWh.
(Calculation: 0.45kW x 24hours x 7days x 52 weeks = 3931.2kWh) - Annual UK emissions from the generation of electrical energy to power 1 x 400W metal halide high bay fitting is 1.69tonnes CO2.
(Calculation: 3931kWh x 0.43kg CO2 = 1690kg CO2 = 1.69tonnes CO2) - Distance travelled by Renault Megane 1461cc car for emissions to equal 1.69tonnes CO2 is 14083km.
(Calculation: 1690kg CO2 / 0.12kg CO2 / km = 14083km) - One adult share of CO2 emissions for return journey from London Heathrow to Denver USA is 1.69 tonnes CO2
(Source: British Airways / Climate Care Online CO2 calculator www.climatecare.org/britishairways) - UK Industry contributes 55% of annual emissions
Energy Industries: 208 million tonnes
Other Industries: 99 million tonnes
Total: 556 million tonnes
