Microsoft is a good example of a corporate with its own science backed targets; the company is aiming for net zero by 2030 and, once achieved, it intends to 'give the carbon back' that the company generated over the last 50 years. Given that Microsoft is aggressively building energy intensive data centres, this is an enormous undertaking. Microsoft has a contract with nuclear power generator Constellation Energy. The firm pays a premium for this renewable energy to power their data centres so it can advertise that fact to customers.
