丹·卡蒙（Dan Kammen），能源教授加州大学伯克利分校和奥巴马政府的气候顾问，讨论碳税的潜力在最近的清洁能源部长（CEM7）在旧金山会议。
“If we really want to bend the curve to make the transition, we need everyone to speak the same language — not always to agree, but to talk about things in the same way," said Kammen. "You just can’t get environmentalists and business leaders and elected officials to do that unless we’re valuing and pricing out the impacts. Carbon tax will get us there."
卡蒙（Kammen）认为，美国政府可以通过将碳核算作为所有联邦合同的“业务要求”来滚动。
