During a major eruption, millions of tons.
Regarding fucose's comment that volcanoes contribute "approximately 100 times what humans put out every year"...this is not in the Wikipedia article and I haven't seen anyone ever claim this that didn't have a political axe to grind.
From the link below: "Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times."

Gas emissions from volcanoes are a natural contributor to acid rain. Volcanic activity releases about 130 to 230 teragrams (145 million to 255 million short tons) of carbon dioxide each year.
This is approximately 100 times what humans put out every year.
