The Green Sports Hub’s consortium made up of representatives of various sports and supported by technical and communication experts met in London on 7 and 8 November in order to discuss the next steps of the project. During the meeting, ACR+ presented the progress of the Self-Assessment Tool which is in its final phase of development. The tool is an instrument for sport organisations, clubs and associations who want to improve their environmental performances by understanding the links between various practices and procedures and their environmental consequences. During the meeting, the partners adjusted the plan for the 2022 test phase of the tool. Regarding the external testing carried out by a panel of expert's validators, ACR+ will conduct a training course so that they can have a prior knowledge of the tool before testing it.
