Fig. 1.
Amount of CO2 emission avoidance available from mangrove protection in megatons (Mt) of CO2 per dollar change in carbon price as a function of cost for different regions and for the world as a whole plotted from the data of Siikamäki et al. (1). Darker areas represent CO2 emissions avoidance available in the 50% of the countries in the world with the best governance, and lighter areas represent the remainder of the world. There is substantial CO2-emissions avoidance available for less than $10 per ton of CO2, but most of it is located in countries with poor governance (5).

Fig. 2.
Amount of CO2 emission avoidance available each year from mangrove protection as a function of total annual expenditure, plotted from data in the article by Siikamäki et al. (1). The different lines represent emission avoidance available in the top 50%, 90%, and 100% of the countries in the world ranked by best governance. Average cost of emissions avoidance is <$10 per ton of CO2 (tCO2) in all cases, but only ∼20% of the avoidable emissions is in the top 50% of countries ranked by quality of governance (5).
