Sainsbury's in £1bn investment to become carbon neutral by 2040

Retailer's plans include cutting down on waste and a plastic bottle deposit scheme

Sainsbury's has pledged to spend 1bn to become a carbon-neutral business by 2040, 10 years ahead of the government's target for a net-zero economy.

The supermarket chain said the 20-year programme would include cutting its carbon emissions, food waste, plastic packaging and water usage, while increasing recycling, promoting healthy and sustainable eating, and ensuring that its operations are net positive for biodiversity.
