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).
This methodology quantifies the GHG emission reductions generated by washing jet engines. All jet engines become contaminated through normal operation which leads to higher fuel consumption. Jet engine washing eliminates contamination and improves the efficiency of the engine, resulting in decreased fuel use and a reduction of carbon dioxide emissions.
This methodology is applicable to projects which utilize on-wing jet engine washing as a means to improve jet engine propulsive efficiency.
