All it takes for a reduction in emissions is for the volcano's emissions to be less than what the grounded planes would have been.
And seeing as emissions are estimated tell us how you can estimate that?

"Based on readings taken by scientists during the first phase of Eyjafjallajokull activity last month, the website Information is Beautiful calculated the volcano has emitted about 150,000 tonnes of CO2 each day."
and from the Information is Beautiful Website-
"UPDATE 3 – 20th April – More new info and some shame for us. According to leading geologists, Eyjafjallajoekull is emitting between “150,000 and 300,000” tons of CO2 a day (source). Despite the attentions of the Icelandic vulcanologists and detailed research, our calculations were apparently off by a factor to 10. Many apologies for this error. The volcano *is* belching huge gobs of CO2 into the atmos.
Arguably, still less than the amount that would’ve been emitted by the grounded planes. We’ve corrected the diagram. Thanks to all the commenters who helped us refine and correct our calcs."
So perhaps not.

China's emissions are irrelevant (unless of course you think they only emitted for the 8 days that the planes were grounded)
You only wish they were. China cheated for years.
