Message : Required fields LONDON (Reuters) - British insurer Aviva plans to become a net zero carbon emissions company by 2040, it said on Monday, claiming this was the most demanding target set by any major insurer worldwide. Following the 2015 Paris Agreement on climate change, many countries and companies are aiming for net zero carbon emissions by 2050, to limit global warming to 1.5 degrees Celsius above pre-industrial norms. The insurer plans to reach net zero carbon emissions from its investments by 2040 and net zero from its own operations and supply chain by 2030. "For the world to reach net zero, it's going to take leadership and radical ambition," Aviva Chief Executive Amanda Blanc said in a statement.
