CO2 Emissions
CO2 emissions arise from the consumption of fuel and electrical energy. Alternate fuel types are used in generation, for example Coal, Oil, Gas, Nuclear and Wind, each have an associated CO2 emission per kWh of energy.
For most consumers, power will be drawn from the multiple sources connected to the national grid in which case the Carbon Trust and DEFRA advise using a value of 0.537 kg CO2 per kWh to establish emissions.
Electricity is only part of the CO2 story for street lighting, however significant emissions are associated with fuel consumed by maintenance vehicles, manufacture and distribution of spare parts and of course, disposal of parts at the end of life. It is therefore important to understand the life cycle carbon footprint of the street lighting installation since choices made around capital cost can, for example, result in substantially higher carbon footprints.
Today Stela has a life cycle carbon footprint on the lowest scale compared to other street lighting solutions.
