This page catalogs 796 sustainable construction and infrastructure projects, spanning green building materials, energy-efficient commercial real estate, and infrastructure designed to reduce environmental impact. Examples from the directory include JUUNOO (modular, energy-efficient commercial workspaces), Gravalock (permeable paving to reduce stormwater runoff), Habitech (sustainable building and energy efficiency consulting in Italy), and Rock-Cell (building materials made from captured CO2). The sub-category Green Building narrows this further to material and design-specific projects. Construction and infrastructure account for a large share of global emissions and resource use, which is why this category connects closely with SDG 9 (industry, innovation and infrastructure) and SDG 11 (sustainable cities and communities). What counts as a Construction & Infrastructure project on Keys for Tomorrow? A project is tagged Construction & Infrastructure if sustainability or positive impact is core to how it operates in this space, not a side claim. There are currently 796 construction & infrastructure projects catalogued on Keys for Tomorrow.
