Fig. 2: Substantial cross-regional disparity in cost of carbon mitigation.
From: Contrasting suitability and ambition in regional carbon mitigation

The RCC (average reduction cost of carbon) for each region under each scenario (unit: US$ per tCO2). Red color denotes regions with positive value of RCC, and blue color represents regions with negative value of RCC. Detailed value of RCC for each region under each scenario can be found in Supplementary Data 3.
