Draft protocols are available for consultation with the user-community, stakeholders and subject experts prior to formalisation and initiation of the systematic review; each draft will be posted on the web for a one month period for this purpose. Draft protocols also undergo formal peer review: for details of this process, please refer to our Peer Review Policy. Once comments have been collated, these are then returned to the review team, who should respond to them and produce a finalised version which is stored in the Review Team's CEE Webpage (available at "Reviews in progress" or "EE Library of Completed reviews" depending on the advancement of the systematic review).

For a detailed description of the function and content of a protocol, please refer to the Guidelines for Systematic Review in Environmental Management. For more details on the structure and a template for protocols submitted to the Collaboration for Environmental Evidence, please see our 'Information for Authors' page.
