Sustainability refers to meeting present needs without compromising the ability of future generations to meet their own needs, typically encompassing environmental, social, and economic dimensions. Environmental sustainability involves protecting ecosystems, reducing pollution, and managing resources responsibly. Social sustainability addresses equity, community wellbeing, and quality of life. Economic sustainability ensures financial viability over time. Municipalities pursue sustainability through land use planning, infrastructure investment, procurement practices, operations, and community programs. Sustainability frameworks guide decision-making by considering long-term impacts alongside immediate needs. Many municipalities have sustainability plans or strategies with targets for emissions reduction, waste diversion, green infrastructure, and other sustainability objectives. Sustainability increasingly influences all aspects of municipal planning and operations.
