The European Union proclaimed a new era in the fight against climate change on Wednesday as it announced sweeping measures to cut greenhouse gases and boost renewable energy use, and called on the world to join forces in "the great project of our generation".
José Manuel Barroso, the European Commission president, said the EU was supporting its words with actions that laid foundations for an international deal to cut greenhouse gas emissions. "If we want a global agreement it is absolutely indispensable that Europe . . .leads the way to get others to follow," he said.
