Well, China wasn't communist in 1930; that aside, I think it's tough to get an accurate idea of one specific time in the past, as such I think we're better off trying to understand the general situation over the situation over a longer-term in the USSR. Here is a quote from a self-professed socialist on a socialist website about the environmental situation there:

>"On this basis, let me agree with Adam that the damage done to the environment by the Soviet regime and its successor doesn’t remotely bear comparison with that in the West. It was, and remains, catastrophically worse. Particular countries elsewhere, especially in the developing world, have suffered one or another ecological disaster, sometimes of mind-bending dimensions. The USSR managed something in just about every sector of heavy industry to match the worst of them."
