The Clean Air conference series has taken place in Portugal 
since 1991 and since 2009 organized by the present 
committee. Since the first edition the conference has 
provided a good opportunity to promote exchange of 
information between academic and industrial participants in 
parallel with an enjoyable stay in Portugal.

The conference deals mainly with techniques to reduce the 
impact of fossil fuel utilization or the use of alternative 
fuels including, the development of CO2 capture 
technologies, the use of biomass and other fuels, the 
improvement of equipment operation to maximize energy 
utilization, fuel processing technologies, etc. The 
conference addresses a large range of applications ranging 
from small scale appliances and engines for transport to 
industrial and power plants.

Both, academic and applied contributions are welcome but 
particular efforts will be made to stimulate papers from 
industry and end users in general. The conference format has 
mainly oral presentations and a poster section to promote 
discussion of results. The conference includes a reception, 
an afternoon tour and a farewell dinner with plenty of time 
to make personal contacts.
