Simone Pieber opened a general discussion of the paper by Spyros Pandis: from your presentation together with recent source apportionment studies such as e.g. Crippa et al. for Europe, 1 the relative importance of other emissions from the residential heating and cooking sector, especially wood combustion, becomes more and more evident. Despite this, big efforts are still being made to clean up emissions from the transport sector. Do you think this is still relevant, or should we focus our

Spyros Pandis answered: This is an excellent observation and it is one of the main points that our paper tries to make in the "Age of Foolishness" section. While transportation remains a signicant source sector in urban areas, its importance has been decreasing. Despite this change, the required rebalancing of our control efforts is not happening in most cities. This is partially due to inertia: we have all been taught that transportation is the main cause of air quality problems in big cities and we have a hard time realizing that all our efforts to control it are actually having an impact and what was true in the 1980s and 90s may not be true any more in the 2010s. The second problem is the challenge of dealing with a lot of small individual sources and a lot of people responsible for these heating and cooking emissions. These two obstacles together have made progress in controlling these "non-traditional" urban air pollution sources difficult.
