Ecoplan, together with Infras and other partners, has recalculated the external effects of transport in Switzerland for 2021. The previous methodology was specifically reviewed and revised.

As a result of various methodological adjustments, the external costs of total transport are significantly higher than those calculated using the previous methodology. The main reasons for this significant increase are the higher climate cost rate (which is now based on the expected damage instead of avoidance costs as previously), new dose-response functions (e.g. the link between air pollution and the frequency of premature deaths) and the inclusion of the three new diseases dementia, lung cancer and diabetes in air pollution.
