Part of the tax revenue should be channeled into subsidies for new low-carbon energy sources like wind and solar, and to cover the costs of developing CCS. These subsidies could start fairly high and decline gradually over time, as the tax on CO2 emissions rises and the costs of new energy technologies fall with more experience and innovation.
部分税收收入理应为风能和太阳能等低碳新能源提供补助，并用于支付碳捕获封存的成本费用。低碳补助开始可能很高但随时间推移逐步下降，因为在二氧化碳排放税增加的同时，新能源技术成本会随着经验和创新而不断下降。
