Industry decarbonisation is a cornerstone to reach net-zero emissions by this mid-century. The diversity of industrial activities, processes and products, the complexity of global industrial value chains, and the international competition make industry decarbonisation a challenging objective. Annual investments in low-carbon technologies for industry decarbonisation need to increase by a factor of three to five by 2030 compared to current levels to align industrial emissions with net-zero pathways. This paper analyses available financing solutions to scale up investments at pace, especially in emerging and developing economies where industrial production is growing rapidly whilst available finance is limited. It highlights de-risking and financial instruments and models that can help accelerate investments and draws lessons from twelve financing industry decarbonisation case studies which demonstrate how private capital can be mobilised.
