The 3rd Expert Forum on Atmospheric Chemistry (EFAC 3) will take place on 5./6. December 2016 in Frankfurt am Main at DECHEMA Society for Chemical Engineering and Biotechnology. EFAC 3 focusses on the identification and analysis of the interrelations between air quality and climate change that are associated with various new and emerging technologies of societal relevance. The specific aim is the attempt to quantify such effects with respect to unexpected consequences and their local, regional and global significance. The motivation is the integrated assessment of technologies prior to their full implementations into industrial and/or societal applications. One of the most prominent characteristics of current new and emerging technologies is a reduced demand of energy and an effective contribution to mitigate climate change. This is most efficiently achieved by increased or more effective use of catalysis and/or CO2 free or neutral technologies. What is quite often forgotten, however, is that climate mitigation – with the exception of direct savings in CO2 emissions – is closely related to air quality and vice versa.
