Can Extractive Industries Promote Sustainable Development? A Net Benefits Framework and a Case Study of the Marlin Mine in Guatemala

Abstract

This article develops a framework to evaluate net benefits from mining and utilizes it to assess the Marlin mine in Guatemala. The framework integrates “weak” and “strong” sustainability principles. Under weak sustainability, a net gain in human welfare can substitute for the loss of nonrenewable resources. Under strong sustainability, nature’s life-support systems are not substitutable. We define “net benefits” as the joint generation of net gains to human welfare, defined as local acceptance and high economic benefits, and low risks to the resilience of environmental life-support systems, especially water, evidenced by best practice management standards. We find little evidence that the Marlin mine meets either weak or strong sustainability criteria: there is strong local resistance to the mine and economic benefits are low, while environmental risk is high, especially in terms of potential long-term contamination of life-supporting ground and surface water.
