The naturemade star quality label is awarded for energy generated through particularly environmentally friendly processes. Naturemade star eco-energy comes from 100% renewable sources such as water, sun, biomass and wind, and the label certifies that further stringent, comprehensive environmental conditions are met.
Certification of energy generation under the naturemade star label takes the natural environment, i.e. the plant and animal species living around power plants, into particular account. This is especially important as the ever increasing use of renewable sources of energy impacts on habitats and thus biodiversity.
Environmental protection and upgrades are of particular importance when using hydroelectric power, which is why hydroelectric power plants to be certified under the naturemade star scheme not only need to comply with the relevant criteria, but operators must also pay one centime per kilowatt-hour of electricity sold into an environmental improvement fund.
