Emission calculations of energy-consuming sectors are generally performed based on average emissions from energy production. As outdoor lighting is used only during certain time of the day, the emissions calculated on the basis on average energy production differ from the actual emissions. This article uses time-specific data of both outdoor lighting energy consumption and carbon dioxide emissions from energy production in Finland. The results show that in 2008 prior to the major changes due to EU legislation in outdoor lighting, the carbon dioxide emissions based on the time-specific data were 141 000 t. The emissions were 128 000 t calculated with the average CO2 factor in 2008 (160 g CO2/kWh) and 160 000 t calculated with the frequently-used estimate for CO2 emission factor (200 g CO2/kWh). The estimated night- and summertime shutdowns of outdoor lighting reduced the emissions by 15 % to 120 000 t. It is recommended to use accurate, time-specific emissions in the emission calculations of products that are not constantly used throughout the day and year in order to calculate emissions and potential emission savings more accurately, especially in case of products of considerable energy consumption.
