Underlining why gender equality is a core component of sustainable infrastructure design, this report considers four key ADB investment sectors in Asia and the Pacific and sets out ways to evaluate gender-enhanced project outcomes. The report outlines theories of change and indicators designed to enable gender-inclusive infrastructure investment in urban development, transport, energy, and water, sanitation, and hygiene. Designed to serve as a point of reference, it shows how better including the needs of women, increasing their role in decision-making, and raising stakeholder understanding can help deliver projects that work for everyone.
