U.S. industries that rely heavily on energy and face competition from imports would be most vulnerable under a cap-and-trade system to limit greenhouse gas emissions, according to testimony delivered Wednesday by RFF Senior Fellow Richard Morgenstern before a House energy and environment subcommittee.
The hearing on the potential leakage of jobs and carbon emissions under cap-and-trade addressed a broad spectrum of concerns, from foreign trade relations to consumer energy costs.
In his testimony Morgenstern highlighted five points
- The total economic impacts of proposed climate legislation are relatively small
- Despite these small impacts, certain energy-intensive and import-sensitive industries are likely to suffer
- These impacts should decline over time
- Accurately identifying the most affected industrial segments is not simple
- Emissions leakage is clearly a long-term problem in certain sectors
He added that flexibility could be built in to a carbon pricing system to ease financial burdens on the most-affected sectors and reduce leakage. He identified the provision of free emission allowances to vulnerable firms based on their output and emissions intensity as a "very attractive option," especially in comparison to the imposition of border taxes or the creation of special exemptions.
Morgenstern's testimony drew from his research with Mun Ho and Jhih-Shyang Shih as well as a recent discussion paper from Carolyn Fischer and Alan Fox
Wednesday's hearing came a day after Energy Secretary Stephen Chu suggested that under a cap-and-trade system the U.S. may need to consider a carbon tariff on imports from countries that lack similar policies.
