Green and Galiana calculate the benefits – from reduced warming and greater prosperity – and conservatively conclude that for every dollar spent this approach would avoid about $11 of climate damage. Compare this to other analyses showing that strong and immediate carbon cuts would be expensive, yet achieve as little as $0.02 of avoided climate damage.
每年投资约1千亿美元用于非碳源能源的研究，将意味着我们能够在本世纪内基本解决气候变化的问题。格林和加利亚纳计算出了这样做的收益——从降低全球变暖到取得更大的社会繁荣——并且得出保守结论，每花费1美元，这个办法将会避免大约11美元的气候变化损失。把这个结果同其他分析对比，过于剧烈和迅速的碳减排方式将十分昂贵而且回报甚低，1美元投入能够避免的气候损失仅为0.02美元。
