In the context of modern environmental management, assessing the impact of corporate activities on areas with high biodiversity has become essential to support truly sustainable development. Regulatory pressures and growing environmental awareness are pushing many companies to integrate biodiversity criteria into their sustainability strategies, particularly to comply with CSRD and Carbon Disclosure Project (CDP) directives. The CSRD mandates reporting obligations for companies on environmental impact, including biodiversity, while the CDP, still voluntary for this aspect, is expected to become mandatory, requiring companies to identify the biodiversity zones impacted by their sites. This thesis describes the design, development, and implementation of a web application for assessing biodiversity impact at corporate sites, developed for EcoAct, an environmental and climate consulting firm.
