Within a factory emitting a pollutant to the environment standards may be set relating to production methods, either to protect workers or to ensure that the minimum amount of pollutant is eventually discharged to the environment. The IPPC Directive requires regulators to prescribe methods of operating plants to minimize emissions to the environment and the Directives on worker protection (see Section 7.10) set standards to protect workers. The Regulation on eco-management and audit (see Section 11.8) also encourages companies to take a wider view of the overall operation of their activities to, inter alia, improve production methods and so reduce pollution.
