Abstract
Background: Industrial and urban development intensifies emissions, energy use, water consumption, waste generation and residual exposure, requiring mitigation approaches that move beyond isolated compliance. Aim: This study evaluates how environmental regulation, green supply-chain governance, digital monitoring and nature-based solutions can reduce environmental aspects and impacts when applied separately and as an integrated portfolio. Methodology: A qualitative integrative review was combined with a coded evidence matrix of 150 industrial and urban-interface observations across five regions, eight sectors and five mitigation bundles. Outcomes were assessed through emissions, energy, water and waste reductions, payback period and composite environmental performance. Results: Across all observations, emissions fell by 22.0%, energy use by 22.8%, water use by 15.2% and waste by 21.6%. Integrated strategies produced the strongest results, achieving 31.8% mean emissions reduction, 31.4% energy reduction, 29.7% waste reduction, a 98.7 performance score and a short 1.21-year payback. Digital maturity and sensor coverage strengthened performance, while procurement and supplier audits extended mitigation upstream. Conclusion: Environmental impacts are mitigated most reliably when regulation, procurement, digital evidence and urban ecological buffering operate together as one evidence-driven management system. The findings support portfolio-based policy and management, reducing impact shifting while improving operational, financial and environmental outcomes across diverse sectors.
