assess the success of the measures taken to reduce water consumption. Waste The EMAS environmental core indicators on waste are: Wa1: Total annual generation of waste, broken down by type, expressed in tonnes Wa2: Total annual generation of hazardous waste, expressed in kilograms or tonnes Hazardous wastes cause harmful environmental effects. As a result, the EMAS Regulation is clear on the fact that hazardous waste has to be reported under a specific indicator. Biodiversity The EMAS environmental core indicator on biodiversity is: B: Use of land, expressed in m2 of built-up area By using the indicator, organisations can start monitoring their impact on ecosystems or habitats, through their land use. Emissions The EMAS environmental core indicators on emissions are: Em1: Total annual emissions of greenhouse gases, expressed in tonnes of CO2 equivalent Greenhouse gas (GHG) emissions of an organisation indicate an organisation's impact on the climate. The indicator does not only focus on carbon dioxide emissions but also on other GHGs (see list above). Em2: Total annual air emission The indicator requires an organisation to report on several air emissions (see list above). Using this indicator gives an organisation a thorough understanding of its impact on air quality. ISO 14001 All organisations listed in the EMAS-Register run an environmental management system according to the EMAS requirements. Because ISO 14001 is an integral part of EMAS, these organisations automatically comply with the requirements that the international standard demands as well. However, EMAS registered organisations fulfill requirements that go beyond the scope of ISO 14001. EMAS registered organisations demonstrate: Credibility: the proper implementation of EMAS is assessed by qualified and independent environmental verifiers. Transparency: by periodically reporting on their environmental performance. Those reports include information on key performance indicators. The reports must be validated by an environmental verifier. Continuous improvement process: by committing themselves to continuous improvement of their actual environmental performance. This performance is also evaluated by an environmental verifier. ISO 14001 only requires improving the environmental management system itself. Compliance: by fully complying with applicable environmental legislation. Stakeholder engagement: by involving employees and other stakeholders in order to benefit from their commitment, ideas, skills and experiences. Benefits and costs EMAS is a comprehensive and demanding premium label, whose implementation requires some financial and personnel resources. In return, EMAS provides organisations with many advantages that can easily outweigh these costs. As EMAS is tailored to individual performance improvements, each organisation has
