Today, governments, industries, and societies are grappling with the question: Who should take responsibility for addressing climate change? What roles do governments, industries, and individuals play? This debate happens not only in international climate policy discussions but also in the daily lives of people and communities. We were happy to join as Guest Speaker the SMU-Course "Environmental Policy and Politics", led by Dr Jude Kurniawan and provide an industry and practitioner perspective to these key questions. It was great to share our experiences and insights with the close to 40 students and "surprise" them with our hands-on approach towards sustainability in schools. None of them has repurposed her/his school uniform and was aware of this green practice and opportunity.
