Which statement best describes sustainability indicators for urban planning?

• A. Sustainability indicators focus on density, land-use mix, transit access, green space per capita, energy efficiency, waste management, and climate resilience.
• B. Sustainability indicators measure only economic growth.
• C. Sustainability indicators ignore climate resilience.
• D. Sustainability indicators are not used in urban planning.

Answer: (A)

Measuring sustainability in urban planning requires a holistic set of indicators that reflect environmental performance, social well-being, and economic viability. The best statement includes density and land-use mix to promote compact, accessible development; transit access to reduce car dependence; green space per capita to support livability and ecosystem services; energy efficiency to cut emissions; waste management to track resource use and recycling; and climate resilience to gauge a city’s ability to adapt to heat, flooding, and extreme events. Together these measures show how land use, transportation, buildings, and services align with sustainable outcomes. The other options fall short because focusing only on economic growth misses environmental and social dimensions, ignoring climate resilience omits a critical risk-management aspect, and saying indicators aren’t used in urban planning contradicts how planners actually guide decisions with measurable targets.
