FAQ

Where does the data come from?

The data on the CO2eq, water and land impact of the food products originates (mainly) from the RIVM and is based on a weighted average of the emissions for the average supply of this product on the Dutch market.

Why these 3 impact factors?

These 3 factors have been chosen because they are the most important indicators of climate problems caused by food production. More explanation about the factors here .

Which factor is the most important?

For global warming, CO2eq is the most important parameter, but this does not mean that the other parameters are not important. Land use and water consumption are also causing many problems worldwide, read more here.
