Non-CO2 Greenhouse Gases: Science, Control, Policy and Implementation
Proceedings of the Fourth International Symposium on Non-CO2 Greenhouse Gases, NCGG4, Utrecht, the Netherlands, July 4-6, 2005

NCGG4 is the fourth in a series of conferences devoted to the science and policy of greenhouse gases other than carbon dioxide. This symposium was especially devoted to the implementation of measures to reduce greenhouse gas emissions.
The Kyoto Protocol entered into force on the 16th of February of 2005 after the ratification by 55 countries, together responsible for 55% of the greenhouse gas emissions. The Fourth International Symposium on Non-CO2 Greenhouse Gases (NCGG4) could not have been held more timely as many countries are more committed now to greenhouse gas emission reductions.
Science has drawn our attention recently to the fact that air pollution may have obscured the actual global warming by global dimming. Therefore during this conference the interactions between trace gases in the atmosphere and especially the ozone chemistry were discussed extensively. Further topics which were discussed to reduce emissions were: science, control, policy and implementation strategies.
Because of the wide attendance from different countries in the world the symposium offered excellent opportunities to discuss policy and implementation issues within the different regions. It has now been widely recognised that the non-CO2 greenhouse gases offer excellent opportunities to contribute substantially to meeting national commitments at relatively low costs.
