Ovo Energy chief Raman Bhatia is to announce his company will end the use of Renewable Energy Guarantees of Origin (REGO) certificates as part of a drive to end industry greenwashing. At an event taking place in London later today (18 April) Bhatia will unveil a series of measures, called Path to Zero, that the company believes the UK needs in order to hit its net zero ambitions, with a warning that without significant change, the country is on track to miss its carbon targets.
