Air Quality is an invisible topic. This makes it difficult to relate to. However with the introduction of the environmental zone in Rotterdam, air quality became an urgent and ‘hot’ topic that has a big impact on people. In order to make the topic more tangible and to start a dialogue we created ‘Luchtloket‘ a mobile ‘counter’ that shares knowledge and gathers input and stories from citizens to transfer this to policymakers. The instrument ‘LuchtLoket’ is designed to make the topic Air Quality tangible in a humoristic strange way. This allowed an open dialogue. We mapped all the opinions.
