Business Green reports that the company is making a firm, long-term commitment to the fight against climate change [businessgreen.com]. Specifically, that commitment includes a promise to slash its own operational greenhouse emissions 60% by 2025, and by 100% by 2050. It has also promised to run on 100% renewable energy by 2030 [treehugger.com]. In the process, it became the first UK supermarket to have its climate change plans approved by the Science Based Targets (SBT) initiative [sciencebasedtargets.org].
Of course, even with these impressive goals, much remains to be done. As WWF's head of climate and energy, Gareth Redmond-King, notes in the Business Green article, Tesco is a major retailer of gasoline and diesel due to the gas (petrol!) stations it runs at its stores. And a related commitment to slash supply chain emissions by only 17% by 2030 is not nearly as impressive as its own operational emissions targets.
