Verra has inactivated this methodology in accordance with Section 5 of the VCS Methodology Development and Review Process v4.3 (PDF), given that no projects using the methodology have been registered within five years of the last update or review. See the announcement, Verra Conducts Quality Review of VCS Methodologies, Inactivates 10 with Low or No Use, for more details. The grace period for listed projects to complete validation is six months in accordance with Section 3.21.3 of the VCS Standard v4.5 (PDF).

Propylene Oxide is used to produce commercial and industrial products including polyether polyols, propylene glycols and propylene glycol ethers. It is among the most diffused chemical intermediates worldwide and its production is on the rise. Industrial production of Propylene Oxide generally involves hydrochlorination or oxidation.

This methodology aims at supporting a new Propylene Oxide production process, known as Hydrogen Peroxide-based Propylene Oxide (HPPO) Technology, that reduces GHG emissions and waste generation from Propylene Oxide synthesis due to the use of less GHG-intensive reagents and reduced process energy requirements.
