The various emissions, including GHG emissions, from electricity production are a crucial part of environmental impact assessments of any kinds of products, services and consumption. Usually average annual emissions are used, but electricity market has lately increased interest in daily-based and hourly-based emission coefficients for electricity. In such markets, where technology mixture of the production includes technologies with widely different emission factors, there is potential for large variation in hourly based emission factors and consequently this offers potential for decreasing GHG emissions by efficient real-time based demand management. In this paper, we determine hourly based GHG emission factors and give examples how GHG emissions may be decreased in households and companies by changing the use patterns, and consequently timing of electricity use, the total amount of electricity consumption being unchanged. Electricity production in Finland, as well as the electricity consumption in Finnish households and companies are used as the cases. The examples from households and companies indicate the potential of managing hourly based demand loads and resulting GHG emissions. So far hourly-based emission coefficients have not been used (at least in significant amounts) in demand management in order to reduce emissions and mitigate climate change.
