This article examines what it would take for the Biden effort at incorporating environmental justice into regulatory decisionmaking to succeed where the Clinton and Obama efforts failed. It argues that agencies will need to be provided with clear guidance on the methodologies used to conduct distributional analysis, and that the lack of a standardized approach is part of the reason prior efforts failed. It further argues that agencies will need to take seriously the already existing requirement of analyzing the distributional consequences of different regulatory alternatives. Otherwise, they will never be in a position to answer the key question in this area: when are the better distributional consequences of one alternative sufficient to overcome another alternative’s higher net benefits?
