Catherine Witherspoon, former Executive Officer of the California Air Resource Board, delivered a speech called Role of Advanced Technology in Cleaning California Air. Drawing from California's practice, she emphasized the importance of implementing Best Available Control Technology for stationary sources and "Technology-forcing approach" for vehicles.

Best Available Technology is used globally. Axel Friedrich, former division Head of Federal Environmental Agency of Germany, shared his observations on how Best Available Technique system was developed and implemented in the Europe.

Another expert Michael P. Walsh introduced the developments of the clean vehicle technologies in the US. He is the Founding Chairman of the Board of Directors, International Council on Clean Transportation.

In an encouraging sign, Chinese companies were also geared up to use advanced technologies in air pollution prevention and control. They compete with overseas companies for the first year's Bluetech Awards in the areas of diesel emission control technology, VOCs pollution control technology, indoor air pollution purification technology and straw recycle technology.

Bluetech Awards, initiated by CAAC in August, aims to push forward the development and implementation of feasible clean air technology. A total 26 technologies were nominated for the awards among 56 collected technologies from 8 countries across the world including the US, French, Germany, Italy, the UK, Australia, Malaysia and China. There are 5 technologies won the Bluetech Awards.
