Some 63 percent of Marks & Spencer products have a “Plan A attribute” — an eco or ethical quality above the market norm — according to the company’s Plan A update.

In M&S’ Plan A 2020 sustainability goals, the company pledges to have 50 percent with a Plan A attribute by 2015 and 100 percent by 2020.

Products recently awarded with Plan A attributes include boxes of Belgian chocolates (now made from 100 per cent UTZ certified chocolate) and all Food-To-Go pasties (the Cornish factory where the products are made has received accreditation for energy and water efficiency).

Also in the Plan A update, the UK retailer says its food delivery team has added 14 nitrogen trucks to its fleet. The trucks, which operate out of M&S’ distribution center in Hemel Hempstead and deliver to stores around London, emit 62 percent less CO2 over their lifetime and zero at point of use.

Additionally, 28 per cent of M&S cotton is now grown to Better Cotton Initiative standards.
