Practically speaking, the single biggest area of low hanging fruit is clean shipping. Right now the largest 15 cargo ships emit more greenhouse gasses than all the cars on the road combined. The US could take the lead on this issue by modifying the Jones Act, a peculiar piece of legislation that forces maritime commerce between US territories to use US ships with an American crew. If the Jones Act were modified to include incentives for zero emission ships it would heavily incentive investment in this critical area. This single change in legislation would reduce the cost of goods and services in Hawaii and Puerto Rico, increase trade, and provide a powerful economic carrot to reduce carbon emissions.
