    Description

    Evaluating Environmental Sustainability through Environmental Reports
    Environmental Management Systems (EMSs) are increasingly adopted
    by industrial organizations to address environmental challenges and
    improve sustainability performance. Among them, the EU Eco
    Management and Audit Scheme (EMAS) is notable for its requirement of
    verified public reporting through Environmental Statements (ESs), aiming
    to ensure transparency, accountability, and continuous improvement.
    However, doubts persist regarding the actual effectiveness of EMSs in
    driving substantial environmental progress, with concerns often raised
    about superficial compliance, inconsistent indicator selection, and the
    limited alignment between environmental goals and outcomes.

    This thesis investigates how EMAS-registered installations translate
    regulatory and voluntary commitments into monitoring, reporting, and
    environmental improvement practices. Focusing on the Italian energy and
    waste management sectors, two industries with high environmental impact
    and strong regulatory oversight, the study applies a structured and
    evolving mixed-methods approach to analyze over 200 Environmental
    Statements. The research is organized into four thematic clusters: reporting
    practices and indicators; performance evaluation and sectoral comparisons;
    monitoring, targets, and effectiveness; and cross-sectoral synthesis and
    policy implications.
    Content analysis of Environmental Statements provides the foundation
    for both qualitative and quantitative assessments. The methodology
    progresses across the thesis to include trend and correlation analyses,
    comparisons against Best Available Techniques Associated Emission
    Levels, and the introduction of novel metrics such as the Combined
    Utilization-Focus indicator.

    Findings show that while EMAS organizations generally focus on
    relevant environmental issues, particularly air emissions, energy use, and
    waste, variability in the quality, completeness, and consistency of the
    reported data remains. Performance assessments reveal that installations
    using cleaner fuels or advanced technologies tend to achieve better
    environmental outcomes and trends. However, critical aspects such as
    biodiversity impacts in hydropower or energy efficiency in waste
    incineration are often underreported. The thesis also highlights a frequent
    disconnect between environmental priorities, investment allocation, and
    reported achievements.

    By providing empirical insights and methodological tools, this research
    contributes to a better understanding of EMS implementation and
    performance. It underscores the potential of EMAS not just as a reporting
    obligation, but as a platform for credible, data-driven environmental
    governance, provided its principles are applied rigorously and with sector
    specific attention.
