This is a list of countries by planetary pressures–adjusted human development index (PHDI), as published by the UNDP in its 2020 Human Development Report. The index captures the HDI of a country adjusted for ecological and environmental factors like carbon dioxide emissions per person and material footprint. According to the PHDI, "The PHDI discounts the HDI for pressures on the planet to reflect a concern for intergenerational inequality, similar to the inequality-adjusted HDI adjustment which is motivated by a concern for intragenerational inequality."
