The Commission on the Chemistry of Volcanic Gases (CCVG) is a sub-commission of IAVCEI, that was formed in the early 1980's to bring together volcanologists and geochemists interested in the study of volcanic gas compositions. Since then seven field workshops have taken place to sample volcanic gases and compare sampling and analytical techniques of the various participating groups. The results of these workshops have been distributed through two peer-reviewed publications: Giggenbach and Matsuo (1991) and Giggenbach et al. (2001) and numerous newsletters.

At the 2000 workshop in Japan, the organizing committee of CCVG decided to broaden the scope of the commission to include scientists interested in all aspects of volcanic and magmatic volatiles:
- ground- and satellite based remote sensing of volatile emissions
- aerosol studies
- analyses of volatiles in melt inclusions of erupted lavas and tephras
- determination of diffuse degassing at volcanoes
- physical modeling of magma degassing
- 'traditional' sampling of volcanic gases using Giggenbach bottles
By broadening the theme of the commission we have brought together a variety of scientists who apply different but complementary techniques to understand magma degassing and volatile emissions from volcanoes. We feel that the complexity of magma degassing, the role of volatiles in eruptive processes and the potential effects of volcanic emissions on the Earth's atmosphere call for an interdisciplinary approach. The Volcanic Gas Workshop held in 2003 in Nicaragua and Costa Rica provided a forum for scientists interested in all aspects of magma degassing and an opportunity to apply their specific techniques to 3-4 active volcanoes. Following the tradition of CCVG, participants are encouraged to report their results for inter-comparison.
