High-income countries have promised to help low-income countries invest in climate safety, both in terms of low-carbon energy and resilience against climate shocks. Specifically, they have promised $100 billion in climate-related financing per year, starting in 2020, up from around $25-30 billion this year.
此外，来自碳税的新收入将是政府的福音。高收入国家已承诺帮助低收入国家进行气候安全投资——包括低碳能源和应对气候冲击的恢复力方面。具体而言，它们承诺从2020年开始每年给予1,000亿美元的气候相关融资，而今年这一数字为250—300亿美元左右。来自二氧化碳税的新收入将是兑现这一承诺的理想途径。
