Post-pandemic, there is a growing recognition that higher education needs to take a more proactive role in addressing the United Nations' Sustainable Development Goals -- the 17 goals for 2030 that aim to balance global economic development with the need to tackle climate change and protect our natural ecosystems. This change of focus has profound implications for international higher education. For universities in countries like Australia, New Zealand and the UK, internationalisation has underpinned a successful business model. Recruiting children of wealthy elites in developing countries and charging them high tuition fees allows universities to invest in research and facilities and drive themselves up global rankings tables. But recruiting students from the Global South imposes an environmental cost in terms of the carbon footprint and perpetuates structural inequality. This article explores solutions to moving beyond the current business model and adopting an internationalisation strategy that prioritises social justice and environmental sustainability.
