CMI Highlight: Critical mineral mines do not necessarily have greater social acceptance
CMI researchers at Colorado School of Mines conducted the research for this highlight
Innovation
Critical minerals can bridge interests in security, economy, and environment. This research analyzed whether critical minerals’ links to green technology led environmentalists to shift from opposition to acceptance.
Achievement
Interviews with a diverse set of stakeholders in Minnesota revealed clear trends in the responses to proposed mines that would produce copper, nickel, and cobalt. Traditional critics of mining contested the way criticality was defined and operationalized and ultimately did not believe local environmental harms were justified by the potential green tech, or energy transition benefits the mines could provide.
Significance and Impact
Critical minerals framing does not provide a “get out free” card – the classic dynamics of support and opposition remained largely unchanged. The urgency around critical minerals is often taken for granted in policy circles, but this research underscores that critical mineral designation can have limited influence for other audiences.
Hub Target Addressed
Assessing economic, environmental, and social acceptance impacts.
