About Ilmastodieetti is a carbon footprint calculator provided by the Finnish Environment Institute (SYKE). It can be used to calculate your personal carbon footprint including housing, passenger transport, food, waste and the consumption of products and services. The calculator is designed for Finnish conditions. It was first launched in cooperation with YLE, Finland's national public service broadcasting company, in 2010 when the Ilmastodieetit (Climate diets in English) TV series was broadcast. The first version of the Ilmastodieetti calculator was developed in cooperation with the climate neutral municipalities network (HINKU). The calculator was updated and new features were added in 2013 in cooperation with the Ecohome project funded by the Ministry of Environment.

How does Ilmastodieetti calculate the carbon footprint?

The calculated carbon footprint is an estimation based on the input data. For instance, in a block of flats the heating energy consumption is rarely measured for each apartment. The consumption of goods and services is estimated based on the expenditure of each consumption category and the emission intensity of each consumption category on the level of the national economy. Defining a carbon footprint for each and every product would require global and detailed data collection. The calculation model and principles are updated when improved data are available. The latest update is from 2016.
