INFLUENCE OF FOUR POLICY MEASURES ON THE EMISSIONS OF ATMOSPHERIC POLLUTANTS AND GREENHOUSE GASES FOR A CENTRAL EUROPEAN CITY

In this study, the emission changes for the city of Brno in the Czech Republic following the implementation of four policy measures focused on transport and energy were assessed simultaneously for nine air pollutants and three greenhouse gases (GHGs). The policy measure related to the reduction of the motorised vehicles in the city and subsequent increase in use of soft transport was the one with the highest emission reduction potential for most of the compounds investigated (e.g. up to 13% decrease for PM2.5 and NOx). Such type of measures, which have a higher positive effect on human health and climate change than those on low-carbon vehicles, are difficult to implement as they require a behavioral change. Therefore, they should be implemented along additional measures which can be easily implemented such as those on the replacement of old coal-fired boilers. This study highlighted the need for an integrated impact assessment of policy measures, considering both air pollutants and GHGs.
