Sainsbury's has made good progress in the first year of its 20x20 sustainability strategy, the supermarket reported to stakeholders at an event in London on 20 November.
The strategy features 20 commitments to be achieved by 2020.
So far the supermarket has achieved a 6% absolute cut in carbon emissions from its operations since 2006/07, despite increasing retail space by a quarter over the same period.
It achieved the reductions by retrofitting energy efficient technology in existing stores and building greener ones. For example, its new store in King's Lynn, Norfolk, which opened on 21 November, is fitted with 1,000 solar panels, a ground-source heat pump and natural refrigeration.
