Toward Climate-Neutral Heavy Industry: An Analysis of Industry Transition Roadmaps

Global efforts to decarbonize heavy industry remain insufficiently aligned. While relatively new forms of international collaboration between and among states and companies are emerging, there is still considerable room to embark on more structured knowledge-sharing activities and coherent action among nations. In order to assess the concrete needs of an industry transition at scale, this paper analyzes 29 industry transition roadmaps across 13 countries, spanning the value chain of extractive, processing, and end-use heavy industry sectors. We compare and contrast these roadmaps according to the degree of ambition in decarbonization targets, the financial costs of implementing the roadmaps, and the key mitigation measures to achieve decarbonization targets. Importantly, this paper synthesizes and categorizes key policy, finance, and technology requirements called for to enable roadmap implementation. We demonstrate that the implementation of roadmaps across different industries and countries encounters common and comparable barriers and challenges, highlighting the need for international cooperation to facilitate global industry transitions.
