The supermarket giant said it would use the investment to “implement a programme of changes” to focus on reducing its carbon emissions, food waste, plastic packaging and water usage, as well as increasing recycling, biodiversity, and healthy and sustainable eating.

The grocer will work with the Carbon Trust to asses the level of its current emissions and “set science-based targets for reduction”, publicly reporting those findings every six months.

Its targets will align the retailer with the goal to limit global warming to 1.5°C in line with the Paris Agreement.
