The impact accounting methodology is developed and released on a rolling basis until a complete set of social and environmental impact topics and relevant industry methodologies have been issued. The work plan to develop new topics is released annually and updated as necessary.

A 2025 Work Plan has been released, identifying the series of topics planned for development over the year. All methodologies undergo a public comment period following a period of research and development, and are overseen by the independent Valuation and Technical Practitioner Committee (VTPC).
