Environmental monitoring ENVIRONMENTAL FOLLOW-UP The last stage in the process, environmental follow-up, begins as soon as construction is completed. Depending on the project and its potential impacts, follow-up may continue over a period lasting a few weeks to several years. This stage provides an opportunity to verify whether the techniques used and the mitigation measures were effective in protecting the environment. Any unanticipated problems are also identified, so that appropriate corrective measures can be taken to ensure sustainability for surrounding environments.
