Sustainability reporting frameworks are important for companies to create comparable reports on their environmental and social impacts. International organizations like the United Nations and the Global Reporting Initiative have developed standards for companies to follow. These frameworks help organizations develop their sustainability strategies and reporting processes. Some well-known frameworks include the GRI Standards, UN Global Compact, and ISO 26000 Guidance Standard. Sector-specific frameworks like GRESB focus on specific industries like commercial real estate. These frameworks help companies measure and report on their sustainability performance.
