Consider the following infrastructure sectors: 1. Affordable housing 2. Mass rapid transport 3. Health care 4. Renewable energy On how many of the above does UNOPS Sustainable Investments in Infrastructure and Innovation (S3i) initiative focus for its investments?

Answer: C. The UNOPS S3i initiative focuses on three of the four sectors (affordable housing, health care, renewable energy). The Sustainable Investments in Infrastructure and Innovation (S3i) is a United Nations Office for Project Services (UNOPS) programme launched in 2018 to mobilize private capital into Sustainable Development Goal-aligned infrastructure. The three focus sectors are: (1) Affordable housing: YES — addressing global housing shortage in developing countries. (2) Mass rapid transport: NOT a S3i focus. Transport infrastructure is handled by other UN/MDB programmes. (3) Health care: YES — including hospitals, clinics, health worker accommodation. (4) Renewable energy: YES — solar, wind, biomass projects, particularly in low-income countries. So three of the four (1, 3, 4).
