Winner: Graphic design 2020. Berry Creative has designed a series of stamps that reveal the environmental impact of climate change when heated.

The Post of Finland commissioned the design to make a series of stamps on climate crisis, which are printed using heat-reacting ink. The stamps depict snowy winters, limited immigration and a certain bird endemic to Finland.

When heated, the stamps reveal the future state of possible consequences of the climate crisis. They show snow turning into rain, mass immigration due to heat-ruined areas further south, and the extinction of many of Finland's endemic species.

A sense of urgency was added with the die-cutting and colour scale of the stamps.

Judges comments: "The climate change stamps raise awareness of something we as designers feel very deeply about. Using a simple, everyday image to promote an important sustainability message is a great initiative."
