The International Union for Quaternary Science (INQUA) encourages and facilitates the research of Quaternary scientists in all disciplines. The National Committee of the International Union for Quaternary Research (NC INQUA) is the Swiss representative within the umbrella organisation INQUA.

INQUA's basic goal is to promote improved communication and international collaboration in experimental and applied aspects of Quaternary research, in order to contribute in practical ways to an evaluation of the scale and rates of global environmental changes during the recent geological past. INQUA promotes greater understanding of the importance of Quaternary environmental and archaeological records in two ways, by engaging with international dialogue and activities concerned with modern global environmental problems, and by funding activities that clarify the background context to these problems, within the Quaternary timescale.

NC INQUA is a working group within the Platform Geosciences.
