(Telecompaper) Telefonica has marked the UN's World Environment Day by announcing that it's now aiming to reach a target of zero net emissions across its four main markets (Spain, Brazil, the UK and Germany) by 2030, rather than the initially planned 2050. In a statement and accompanying video, the company's COO Angel Vila said Telefonica decided to revise its target after achieving a 50 percent reduction in global CO2 emissions in 2019, meeting its 2025 target some 6 years ahead of schedule.
