Purpose -The purpose of this paper is to discuss the measures implemented under the spatial planning law of the Republic of Lithuania, along with various initiatives, to identify whether Lithuania is following the international trend of greening cities.Design/methodology/approach -The authors' analysis is based on an evaluation of the urban theorybased approach towards greening cities and adopting urban agriculture in Lithuania and legal regulations introduced by the Lithuanian government. The paper specifically analyses the legal requirements enshrined in Lithuanian law that are intended to encourage green infrastructure and urban agriculture in cities as part of the adoption of the principles of sustainable development. The paper focuses on Vilnius, the capital city of Lithuania, to gauge the extent to which the new regulations encourage urban greening and agriculture.Findings -The authors' reveals that Vilnius is lacking initiatives with regard to urban agriculture, while existing areas for urban agriculture are disappearing. This is happening despite the promising spatial planning reform in Lithuania, which introduced the principle of sustainable development into spatial planning regulations. This is a cause for concern and should lead to renewed calls for a coherent and ambitious approach to the greening of Vilnius and other cities in Lithuania. Furthermore, the lack of action shows that the vague wording used by the regulations does not actively encourage urban agriculture and even results in ignorance of its virtues. Therefore, more precise regulations on encouraging urban agriculture and greening of the cities should be introduced.Originality/value -This paper is the first to analyse the extent to which the newly adopted principle of sustainable development in spatial planning could affect the greening of Lithuanian cities and encourage urban agriculture. The paper identifies the sequence of opening the meaning of the sustainable development principle in regular legal norms which encouraging the greening and indicates the lack of imperative norms to ensure the due implementation of sustainable development principle.
