ARR (Afforestation, Reforestation, and Revegetation) generates carbon credits by establishing new forest cover on degraded or previously cleared land, enabling long-term carbon sequestration as vegetation grows and restores biomass.
ARR creates new carbon sinks through tree planting or natural regeneration, whereas REDD+ focuses on protecting existing forests from deforestation or degradation to avoid emissions.
ARR projects are developed under Verra’s afforestation and reforestation methodologies VM0047, designed to quantify carbon sequestration from newly established forests, while REDD+ follows VM0048 and mangrove projects typically use VM0033.
ARR is implemented on degraded, deforested, or underutilized land where forest cover has been absent for a qualifying period and where reforestation or regeneration can be sustained over the long term.
ARR projects use periodic field measurements, remote sensing, growth modeling, and third-party verification to quantify increases in biomass and soil carbon over time in line with Verra’s monitoring requirements.
ARR projects create local jobs in nursery operations, planting, maintenance, and monitoring, while promoting sustainable land practices and improving long-term livelihood opportunities.
ARR provides large-scale carbon removal, REDD+ provides emissions avoidance, and mangroves deliver high-density blue carbon, together offering a balanced portfolio of restoration, protection, and coastal resilience solutions.
