Growth‐inducing infrastructure represents transformative yet ignored keystone environmental decisions

Abstract

Abstract As the defining force of the Anthropocene, human enterprise is reshaping Earth's surface and climate. As part of that process, growth‐inducing infrastructure, such as electrical transmission lines, export facilities, and roads, presents nonincremental changes in where and how natural resources are exploited. These projects open intact areas, induce or intensify industrial development, and accelerate carbon emissions. The direct impacts of large‐scale infrastructure are widely acknowledged and policy and legislation exists to account for them in environmental decisions. Yet, decision makers often ignore the secondary, growth‐induced effects, even though they can outweigh the impacts of the initial development. Given the extensive area and magnitude of such impacts, we argue that regulatory or funding approvals for growth‐inducing infrastructure represent keystone decisions. Credible approval processes require the consideration of the full range of impacts resulting from the ensuing growth. This will necessitate a shift in assessment thinking, from the traditional focus on the immediate project footprint to one that recognizes the sustainability implications of approving infrastructure that will transform the trajectory of development at regional and national scales. We identify the characteristics of growth‐inducing infrastructure and provide an overview of methods and policy that can facilitate a deliberate assessment of these keystone decisions.
