Net-zero transition encompasses technology, economy, society, law, and policy across various fields. This project aims to analyze key issues through cross-disciplinary and cross-sectoral assessments, focusing on the characteristics, challenges, and integrated analyses of the four main pillars and twelve key strategies for the 2050 net-zero transition. It prioritizes the cross-disciplinary integration and development of sustainable finance, sustainable energy, and net-zero buildings. Integrating sustainable energy and net-zero buildings, for example, involves analysis beyond legal aspects to include the twelve key strategies like wind/solar power, advanced energy, power systems and storage, building energy saving, and zero-waste resource recycling. Therefore, this approach causes cross-disciplinary and cross-sectoral analysis. The project will leverage integrated quantitative surveys, focus groups, and expert meetings. Unlike traditional legal or policy analysis, it innovatively engages stakeholders in reviewing and monitoring net-zero topics through a participatory, interactive, and feedback-driven process.
