BRUSSELS (Reuters) - The deal reached by European Union leaders in the early hours of Friday to cut net emissions at least 55% by 2030 is a step for the bloc towards having zero net emissions in 2050, the head of the European Commission said. “Today’s agreement puts us on a clear path to climate neutrality in 2050,” Ursula von der Leyen told a news conference after the deal was reached. She said the agreement gives certainty to investors and “will be our growth strategy.” Reporting by Francesco Guarascio and Robin Emmott. Editing by Jane Merriman
