An environmental management system (EMS) provides an organized framework for companies to manage their environmental impacts and responsibilities. The international standard ISO 14001 outlines requirements for an effective EMS. Key elements of an EMS include establishing environmental goals and targets, implementing plans to meet those targets, monitoring performance, and taking actions to continuously improve environmental protection. Environmental auditing evaluates compliance with regulations and the effectiveness of an organization's EMS in managing its environmental aspects. Common types of environmental audits are compliance audits, management system audits, and audits that assess specific areas like energy use, waste generation, or a product's lifecycle impacts.
