We seek input from a broad range of stakeholders as part of the ongoing inclusive, multi-stakeholder process by which the ICAT guidance is being developed. More than 160 technical working group members contributed to this initial guidance.

The 10 guidance documents that comprise the ICAT series of guidance provide methods focused on helping users assess the impacts of policies and actions that:

  • Reduce greenhouse gas emissions,
  • Achieve sustainable development outcomes, and
  • Drive transformational change.

Your comments on the guidance will help ensure that the guidance is clear and meets country needs. Reviewers are encouraged to provide feedback on any guidance documents relevant to their needs and/or experience.

Provide comments using Collaborase 

Our public consultation will be run through Collaborase. Collaborase is an online system that facilitates transparency by collating all submitted comments on one interactive platform. It allows commenters to provide comments by section, save comments and return at a later date and update previously made comments. Collaborase can also be easily accessed with mobile devices such as a smartphone.
