The world is facing a dual challenge of implementing carbon neutrality and sustaining economic growth amidst the whirlwind of climate change. Alongside the NDC targets set by the UN and individual governments, various regulations aimed at achieving carbon neutrality at the private sector level, such as RE100, are being strengthened into international norms. Attempts to activate the voluntary carbon market, although still considered auxiliary measures, are being rapidly introduced. As government-led regulatory carbon markets are delayed, voluntary carbon markets at the private sector level are emerging as catalysts for achieving a net-zero economy. This session aims to answer the following questions: What is the current status of international institutionalization for carbon neutrality and what are the future prospects? What are the characteristics and future challenges of voluntary carbon markets driven by the private sector in major countries? What are the strategies and responses of major global companies to achieve carbon neutrality?
