Climate change: Fertiliser could be used to power ocean-going ships

Climate change: Fertiliser could be used to power ocean-going ships

Science
Ocean-going ships could be powered by ammonia within the decade as the shipping industry takes action to curb carbon emissions.The chemical - the key ingredient of fertilisers - can be burned in ships’ engines in place of polluting diesel.The industry hopes ammonia will help it tackle climate change, because it burns without CO2 emissions.The creation of the ammonia itself creates substantial CO2, but a report says technology can solve this problem.The challenge is huge, because shipping produces around 2% of global carbon emissions – about the same as the whole German economy. Making ammonia is also a major source of carbon. A report by the Royal Society says ammonia production currently creates 1.8% of global CO2 emissions – the most of any chemical ind

RBS bids to escape bailout legacy through change of name

RBS bids to escape bailout legacy through change of name

Business
Royal Bank of Scotland (RBS) says it is to change its name to NatWest Group later this year as it commits to a new future following the taxpayer bailout of 2008.While announcing the bank's annual results for 2019, which included a surge in profits, new chief executive Alison Rose set out a series of new priorities for the lender including incentive-linked targets covering climate and support for ethnic minority entrepreneurs. RBS, which remains 62%-owned by the government, said there would be no impact on jobs through the rebranding of the Edinburgh-based group, which will be widely seen as an effort to shake off the toxic legacy of its rescue.It said that the move was driven by the fact that 80% of its customer base came under NatWest but insisted that RBS branches would remain so named. ...
