President Biden on Friday announced the creation of a White House Office of Environmental Justice, one of several actions to address the unequal burden that people of color carry from environmental hazards.“Every federal agency must take into account environmental and health impacts on communities and work to prevent those negative impacts,” Mr. Biden told a crowd of applauding activists gathered at a Rose Garden ceremony. “Environmental justice will be the mission of the entire government.” Richard Moore, a co-coordinator of the Los Jardines Institute in Albuquerque, N.M., and a co-chairman of the White House Environmental Justice Advisory Council, said the executive order was “answering a decades-long call to put environmental justice at the heart of federal policy.”
