Within days of taking office in January 2021, President Biden signed an executive order establishing the Justice40 initiative, which directed federal agencies to ensure that at least 40% of the benefits of federal investments flow to historically marginalized communities. This article traces how Justice40, as interpreted and enacted by government bureaucrats, academics, industry researchers, and activists, intervenes in the governance of the energy transition it seeks to put into motion. Drawing from ongoing critical participation in energy research and development arenas and taking inspiration from Kim Fortun’s notion of the “informating of environmentalism,” this article argues that Justice40 can be understood as an attempt to informate justice, rendering it into problems that can be understood, manipulated, and audited through information systems. Scrambling to manage their accountabilities to the executive branch, Congress, and the American taxpayers footing the bill for massive infrastructure investments, Department of Energy programs are rolling out intricate systems of quantification, whose objectives of commensurability obscure local conceptions and prioritizations of justice. While Justice40 articulates lofty goals of energy transition enhancing the wellbeing of people who have otherwise been harmed by or excluded from the country’s existing energy infrastructure, its everyday practice has the ironic effect of undermining both epistemic and procedural justice.
