This article places the study of rural environmental activism in the wider context of the Chinese government's promotion of Ecological Civilization (shengtai wenming 生态文明). Ecological Civilization is, we argue, a top-down imaginary of China's future that opens up space for environmental agency while setting authoritative standards for how to frame protests in a logic of science and social stability. The article compares how residents in a small cluster of villages in Zhejiang province dealt with different sources of air pollution over a span of ten years: how, when and why they chose to negotiate with local officials and industrial managers to prevent or reduce air pollution, and what the outcome was. We found that in addition to a consciousness of the right to protest, villagers had come to regard the ability to evoke science in negotiations with officials and industrial managers as crucial for success. We suggest that the forms of environmental activism we observed were in effect “containable protests” that befit the state-initiated national imaginary of an ecologically civilized world.
