In 2003,  with the Law No. 5018 was enacted, strategic plan, performance program and activity reports are envisaged as the basic elements of the performance-based budget system. The system has been implemented in public administrations within the scope of general government since 2008. However, work on the program budget began in 2012. The 2021 Central Government Budget has been prepared entirely in accordance with the performance-based program budget system. In order to implement performance-based budgeting more effectively, a link has been established between performance information and the resources allocated in the budget. Performance information related to programs and sub-programs is produced to support budget decisions and ensure accountability. In this framework, performance indicators related to green budgeting are also evaluated and reported in the budgeting processes. In the central government budget 67 main programs have been determined, and three main programs are directly related to green budgeting. For these core programs key indicators have been identified.that allow international comparison at the government level.  According to Central Government Budget Law, allocated central government budget funds have been distributed to programs that aim to combat climate change and protect biodiversity. The programs are called: “sustainable environment and climate change,” “conservation and sustainable management of forests and natüre, use and management of land and water resources”.
