hi all:

personal, i support there is annual face2face conference. it is obvious of face2face advantages. i suggest that we could not definitely "cut" annual face2face conference. At the same time, have to concentrate on how to reduce co2 emission during the conference. For example, people can not avoid using car anymore, but can focus on find many methodology to reducing co2 emission.

well, the main issue is indeed people taking the plane to a OOoCon. For example if you fly Beijing->Europe and return, the plane causes about 4 tons of CO2 per passenger! That's almost the annual emission of an average Chinese citizen. This discussion is of course very important because we need to find out, if we have an appropriate reason to leave such a big carbon footprint. The emissions causes by people traveling to such an event as the OOoCon can only partly be compensated by acting more responsible in other ways.

Best regards,
Peter
