After the restoration of Lithuania's independence in 1990, the ''Aplinkos apsaugos įstatymas'' (Environmental Protection Act) was adopted already in 1992. The law provided the foundations for regulating social relations in the field of environmental protection, established the basic rights and obligations of legal and natural persons in preserving the biodiversity inherent in Lithuania, ecological systems and the landscape. Lithuania agreed to cut carbon emissions by at least 20% of 1990 levels by the year 2020 and by at least 40% by the year 2030, together with all European Union members. Also, by 2020 at least 20% (27% by 2030) of the country's total energy consumption should be from the renewable energy sources. In 2016, Lithuania introduced especially effective container deposit legislation, which resulted in collecting 92% of all packagings in 2017.
