States’ Compliance to International Environmental Law Obligations: Study Based on Multilateral Environmental Agreements’ Performance in Kenya

States within the international system have always cooperated to attain a common good. The most common tool used to attain their goals is often treaties that make up International Laws. Environmental conservation has emerged as a key concern in the recent years with regard to sustainable development. States that ratify these treaties have to fulfil their obligations to ensure success of their goals. This can only be done through effective compliance. This study sought to gauge the performance of two key multilateral environmental Agreements (MEAs); Montreal Protocol and United Nations Framework Convention on Climate Change (UNFCCC) within the domestic setup of a state party (Kenya). The study population consisted of 22 officials within the environmental sector selected through purposive and snowballing methods. Data was collected through one-on-one interviews and review of official documents and analysed through the use of computer software Nvivo. Effective Compliance in Kenya’s International law obligations was found to be reliant on the existing toolswithin the treaties, cooperation between the two government tiers and grassroot support framework.
