[2nd comment on Johannesen et al. 2016] "These issues warrant serious consideration by the seagrass research community; however, VM0033 does not refer to seagrass SOC 'burial rates' or 'storage.' Projects seeking credits under VM0033 must document greenhouse gas emission reductions over time, relative to a baseline scenario, in order to receive credits. Projects must also monitor changes in carbon pools, including SOC, to confirm that observed benefits are maintained over time. However, VM0033 allows projects to conservatively underestimate project benefits by citing default values for specific accounting parameters, including CO2 emissions reductions. "
