The VCS Program makes a distinction between two groups: a) non-AFOLU projects and Agricultural Land Management (ALM) projects focusing exclusively on emissions reductions of N2O, CH4 and/or fossil-derived CO2 and b) AFOLU projects excluding the ALM projects focusing exclusively on emissions reductions of N2O, CH4 and/or fossil-derived CO2. For the first group, the Project Crediting Period is a maximum of ten years, with the possibility to renew this twice. For the second group, the Project Crediting Period is a minimum of 20 years, with a maximum of 100 years.
