Tesco said it has achieved an 86% reduction in its own-label brandy packaging due to the switch to plastic. It added that it is currently working with suppliers to cut the packaging of products on 4,000 projects.
Tesco has also launched what it claims to be the the lightest ever wine bottle following a project with waste reduction body WRAP and suppliers.
The new bottles weigh 300g and are 30% lighter than Tesco's previous lightest own-label bottles, saving 560 tonnes of glass annually.
Lucy Neville-Rolfe, executive director at Tesco, said: "Tesco is always breaking new ground with innovative approaches to packaging. However more significantly we're working with our suppliers so that we reach our target of a 30% reduction in the carbon impact of the products in our supply chain by 2020."
The supermarket also said that it was continuing its carbon reduction efforts throughout the supply chain, stating that packaging is a small percentage of the overall total.
In January it launched the first of its new "Buy One, Get One Free Later" deals, which it said assists customers in cutting down on food waste. The activity ran across purchases of pineapples, melons, salads and lettuces over a two-week trial period. The retailer is now reviewing customer feedback to establish if the activity can be used in the future.
Last year while speaking at the launch of the report 'Consumers, business and climate change' published by Manchester University's Sustainable Consumption Institute, Sir Terry Leahy, chief executive of Tesco, said that customers needed to be involved in solutions to cut carbon emission levels.
He said that the retailer was was committed to becoming a zero-carbon business by 2050 without purchasing offsets and announced new initiatives to help achieve this.
Tesco is aiming for a 30% reduction by 2020 in the carbon impact of the products in its supply chain. Last year it also extended green Clubcard points to encourage environmentally friendly, carbon-conscious purchasing.
