Here we discuss how personal carbon allowances (PCAs) could play a role in achieving ambitious climate mitigation targets. We argue that recent advances in AI for sustainable development, together with the need for a low-carbon recovery from the COVID-19 crisis, open a new window of opportunity for PCAs. Furthermore, we present design principles based on the Sustainable Development Goals for the future adoption of PCAs. We conclude that PCAs could be trialled in selected climate-conscious technologically advanced countries, mindful of potential issues around integration into the current policy mix, privacy concerns and distributional impacts.

在这里，我们讨论个人碳配额 (PCA) 如何在实现雄心勃勃的气候减缓目标方面发挥作用。我们认为，人工智能在可持续发展方面的最新进展，以及从 COVID-19 危机中低碳复苏的需要，为 PCA 开启了新的机遇之窗。此外，我们提出了基于可持续发展目标的设计原则，以供未来采用 PCA。我们得出的结论是，PCA 可以在选定的具有气候意识的技术先进国家进行试验，同时考虑到与当前政策组合、隐私问题和分配影响有关的潜在问题。
