Confectionery giant Mars' Easter eggs have "tonnes less packaging" according to the company's latest advertising campaign promoting its work in the area.
This week, an advert appeared in free newspaper Metro that claimed Mars had reduced the amount of packaging in its medium-sized Easter eggs by 39%.
Mars is a member of Wrap's Seasonal Confectionery Working Group (SCWG), which was formed to reduce carton weight on medium eggs by 25% in 2009.
The company has reduced carton weight across its ranges by 42%, saving 200 tonnes of cardboard per annum and reduced its plastic insert weight by 35%, saving 69 tonnes of plastic pa.
It has also moved all remaining ranges of eggs, excluding Galaxy Premium Egg, to 100% recycled cardboard.
