This depends on what actions the organisation already has in place, the level of data available and how much time can be spent on accreditation work. All businesses can be accredited within their first year by spending an estimated 4 hours per month; this may be more for large companies. If you have no existing practices in place, it will take up to one year; whereas an organisation that is already monitoring data, has the majority of processes in place and is already working within their community, supporting charities, etc. would be significantly quicker in achieving their accreditation. Sharing the workload across a ‘Green Team’ will make this easier and could reduce the time it takes to get accredited.
