Local governments (LGs) play a crucial role as policymakers and catalysts for change at the local level, making them well-positioned to connect the United Nations’ 2030 Agenda goals with local communities. Therefore, LGs should collect and analyze data to monitor progress toward the sustainable development goals (SDGs) and report on the outcomes. In this regard, webpages on the internet stand out as a valuable tool to enhance accountability in LGs and to promote stakeholder engagement with the community. Thus, this paper aims to analyze whether Portuguese municipalities disclose information regarding the SDGs on their websites, and to identify the main drivers of SDG web-reporting.
