This presentation introduces environmental management systems (EMS) and how Travis Perkins, a UK building materials supplier, implemented an EMS based on the ISO 14001 standard. It defines an EMS as a set of methods for aligning business operations with environmental protection. An EMS follows the PDCA (plan-do-check-act) cycle and aims to increase compliance and reduce waste. Travis Perkins established an EMS to address legal requirements, financial pressures, market pressures, and social pressures. Their EMS consists of an environmental policy, procedures, improvement plans, indicators, training, and communication.
