Green interiors focus on sustainability through policies, incentives, and eco-friendly materials that align with the UN Sustainable Development Goals (SDGs). Materials and finishes with recycled content, such as reclaimed wood and recycled metal, help reduce waste, while renewable materials like bamboo and cork promote resource conservation. Water-saving strategies, including low-flow fixtures and rainwater harvesting, further enhance sustainability. Other criteria for materials and finishes include low-VOC paints, non-toxic adhesives, and locally sourced products to minimize environmental impact. In India, green rating systems such as GRIHA (Green Rating for Integrated Habitat Assessment) by TERI, IGBC (Indian Green Building Council), and BEE Star Ratings for energy efficiency guide sustainable interior design practices, encouraging eco-conscious construction and renovation.
