The United States Ozone Depleting Substances (ODS) Project Protocol and the Article 5 Ozone Depleting Substances Project Protocol provide a standardized approach for quantifying and monitoring the GHG reductions from projects that destroy ODS with high global warming potentials that would have otherwise been vented to the atmosphere. These protocols were first adopted by the Reserve Board in February 2010.
