President Obama on Sunday spoke out against a provision in the energy bill that would impose trade penalties on countries that do not accept global-warming pollution limits.

The passage of the House bill on Friday night was an important, if tentative, victory for the new president, becoming the first time either chamber of Congress had approved a mandatory ceiling on the gases linked to global warming.

He said the House bill was a “comprehensive approach” that included a cap-and-trade program to limit greenhouse gas emissions, incentives for new energy efficiency measures and support for wind and solar energy as well as nuclear power and so-called clean coal technology.
