Other technologies, such as green hydrogen and carbon capture, are still a long way from maturity. Around 50 countries have some form of carbon price, double the number 10 years ago, and another 23 countries are planning to introduce one. The snag is that China’s carbon price is low and the United States doesn’t have a federal levy. Others argue that governments should combine carbon pricing with financial support for the most vulnerable and targeted subsidies for fledgling technologies. To hit climate targets, the carbon price would need to be $135 a tonne in advanced economies and $45 a tonne in large emerging ones by 2030.
