For the Rapid Mitigation Project through sustainable energy transition to take off, current funding needs shoring up. Increased volume and access to finance is necessary for education and training new workers and re-skilling existing workers for the new sustainable energy regime. A key economic issue on which the financial policy to support the Rapid Mitigation Project focuses is how to ensure its cost-effectiveness. The extensive role of the state in mobilising climate finance for the Rapid Mitigation Project underscores the extent of the grasp of the state in the financial arrangement and the degree of public investments on capital formation for the transition. The wartime analogy illustrates how the state can, with policy, legislation and regulation, strengthen the role of public finance in the new climate regime. The scale and volume of needed technology and new highly skilled workforce necessitates a strategic approach for fund mobilisation.
