Whenever the world faces turmoil, a recurring argument emerges: that sustainability and ESG goals should be paused due to costs and complexity. This article argues that this is a fundamental error. Sustainability is not a luxury for prosperous times, but a condition for economic, energy, and geopolitical resilience. The author highlights that energy security and decarbonisation are inseparable, citing the European Central Bank's Frank Elderson, and notes that while the West debates delaying ESG, China is integrating it into its industrial policy. Ultimately, the piece contends that retreating from sustainability in the face of crisis only increases vulnerability and undermines long-term competitiveness.
