Forest estates that still have forest cover function as sources of biodiversity, habitats for wild fauna and flora, and sources of community livelihoods, but they also function as carbon sinks. This function correlates significantly with climate change. We have calculated carbon capture in forested areas and peatlands in three priority landscapes. Our calculations indicate that protecting the remaining forested areas in these three landscapes can reduce emissions and sequester around 238 million tons of CO₂. Stored carbon needs to be monitored through annual measurements and forest areas need protection. These carbon sinks and carbon capture have significant value and provide potential future opportunities under carbon certification schemes like Plan Vivo, VCS, and others to build sustainable long-term programmes important for biodiversity and communities in the landscapes.
