Building on cornerstone traditions in historical sociology, as well as work in environmental sociology and political-economic sociology, we theorize and investigate with moderation analysis how and why national militaries shape the effect of economic growth on carbon pollution. Militaries exert a substantial influence on the production and consumption patterns of economies, and the environmental demands required to support their evolving infrastructure. As far-reaching and distinct characteristics of contemporary militarization, we suggest that both the size and capital intensiveness of the world’s militaries enlarge the effect of economic growth on nations’ carbon emissions. In particular, we posit that each increases the extent to which the other amplifies the effect of economic growth on carbon pollution. To test our arguments, we estimate longitudinal models of emissions for 106 nations from 1990 to 2016. Across various model specifications, robustness checks, a range of sensitivity analyses, and counterfactual analysis, the findings consistently support our propositions. Beyond advancing the environment and economic growth literature in sociology, this study makes significant contributions to sociological research on climate change and the climate crisis, and it underscores the importance of considering the military in scholarship across the discipline.

Bridging the areas of political-economic sociology, the sociology of agriculture and environmental sociology, this study tests two hypotheses derived from a refined theory of foreign investment dependence. The hypotheses state that pesticide and fertilizer use intensity in less-developed countries are both positively associated with foreign investment dependence in the primary sector. The use of such inputs in agriculture production is known to contribute to a variety of human health and environmental problems. Findings for random effects and static score panel regression analyses of 35 less-developed countries confirm the hypotheses, and point to the sociological relevance in assessing the potential social and environmental impacts of both the transnational organization and the relative scale of production in different sectors.

Political-economic sociologists have long investigated the dynamics and consequences of international trade. With few exceptions, this area of inquiry ignores the possible connections between trade and environmental degradation. In contrast, environmental sociologists have made several assumptions about the environmental impacts of international trade, but the assumptions lack theoretical specificity and are thus empirically under-investigated. Bridging these two complementary areas of macrosociology, the present study proposes and tests a structural theory of unequal ecological exchange. The theory posits that more-developed countries externalize their consumption-based environmental costs to less-developed countries, which increase forms of environmental degradation within the latter. To test a key assertion of the theory, a weighted index of vertical trade is created that quantifies the relative extent to which exports are sent to more-developed countries. Using the index, cross-national panel analyses of deforestation, 1990-2000 are conducted to test the hypothesis that less-developed countries with higher levels of exports sent to more-developed countries experience greater rates of deforestation, net of other factors. Results of the analyses confirm the hypothesis, providing support for the theory of uneven ecological exchange. Additional findings correspond with other sociological studies of deforestation, particularly those that focus on the effects of rural and urban population growth as well as level of capital intensity and rate of economic development.
