In January 2021, Gold Standard introduced a rule stating that projects with a crediting period start date prior to 01 January 2016 must demonstrate that the project faces a serious risk of discontinuation without carbon revenue. Projects with a start date from this date onwards do not need to do so.

Full details for transitioning a CDM project to Gold Standard can be found in Annex B of the GHG Emissions Reductions & Sequestration Product Requirements
