Microsoft Sustainability Manager is not a tactical event sustainability app. Its value shows up when event data has to become part of a governed enterprise ESG record, especially for organizations already using Microsoft Cloud, Power Platform, Dataverse, and Power BI.
For event teams, the practical question is whether sustainability reporting has become a cross-functional compliance workflow. If the answer is yes, Microsoft can give the sustainability and finance teams a durable home for data. If the job is a simple estimate for one conference, use a lighter calculator and avoid the enterprise overhead.
