Environmental sustainability is becoming an increasingly vital part of daily business. To monitor the impact of business operations on living and non-living natural systems including ecosystems, land, air and water, Environmental performance indicators (EPIs) can be used. EPIs can evaluate the environmental performance of an organization, product, or service, and provide a firm basis for future targets and improvements. Companies often request Environmental Performance Indicators (EPIs) from business partners – and similarly respond to such requests – in order to incorporate these in reporting and decision-making processes.
