This programme provides housing for low-income communities, applying the Green Building principle to achieve climate change targets by reducing carbon emissions. The programme aims to build 100,000 green affordable housing units by 2024, build and retrofit one million units by 2030 (with a potential emissions reduction of 19-36 MtCO2), and achieve 100% net-zero housing by 2050 (PUPR, 2023). The programme was launched by the Ministry of Public Works and Housing (PUPR: Kementerian Pekerjaan Umum dan Perumahan Rakyat). The IGAHP program is expected to save at least 20 percent water, save at least 20 percent energy, and reduce greenhouse gas effects by 29 percent.
