Inferring fossil-fuel subsidies from patterns in emission intensities
VoxEU: No comprehensive database of directly measured fossil-fuel subsidies exists at the international or the sub-national level, yet subsidies may be crucial drivers of global carbon emissions. This column describes a novel method for inferring carbon subsidies by examining country-specific patterns in carbon emission-to-output ratios, known as emission intensities. Calculations for 155 nations from 1980-2005 reveal that fossil-fuel price distortions are enormous, increasing, and often hidden. These subsidies contributed importantly to increasing emissions and lower growth.
