Green and Galiana propose limiting carbon pricing initially to a low tax (say, $5.00 a ton) to finance energy research and development. Over time, they argue, the tax should be allowed to rise slowly to encourage the deployment of effective, affordable technology alternatives.
格林和加利亚纳提议，可以在初始时限定一个较低的碳排放税（比如每吨5美元）来资助能源研究和发展。随着时间推移，她们指出，应该允许该税率缓慢上涨，以此鼓励高效且价格公道的替代技术的推广利用。
