EU may seek tougher car CO2 rules.

BRUSSELS, Belgium - The European Union may need new rules to force carmakers to cut carbon dioxide because they are unlikely to meet voluntary targets, an EU spokeswoman said. The European Commission will push for new legislation when it reports in December on industry efforts to achieve average emissions for new European cars of 140 grams of carbon dioxide per kilometer by 2008, spokeswoman Mireille Thom said. Japanese and Korean manufacturers agreed to meet the same target by 2009.
