The technical workshop on ways to increase the efficiency and transparency of the budget process was held on the margins of the forty-seventh session of the Subsidiary Body for Implementation on 8 November 2017 in Bonn, Germany. The workshop was held in response to a request by the Subsidiary Body for Implementation at its forty-sixth session to discuss possible ways to increase the efficiency and transparency of the budget process, including issues such as: (a) Options to increase flexibility of the funds in the Trust Fund for Supplementary Activities; (b) Ways to address outstanding contributions to the core budget; (c) The level of the working capital reserve; (d) The allocation of resources in the Trust Fund for the Core Budget of the UNFCCC and the Trust Fund for Supplementary Activities. Given the importance of funding for participation, the workshop agenda also included a fifth topic, on the Trust Fund for Participation in the UNFCCC Process. Representatives of Parties provided input and feedback to the secretariat on the workshop topics, the background papers it prepared and the presentations it gave. This feedback will inform improvements to the budget process.
