(CNN) Greenpeace activists blocked the entrance to Coca-Cola's UK headquarters in London with a 2.5-ton sculpture featuring a seagull regurgitating plastic, and called for the company to do more to help prevent plastic pollution. The campaign group said the sculpture, which depicts an idyllic family beach scene interrupted by birds choking on plastic, was intended to highlight what it claimed were failings by the company. In a report released on Monday, Greenpeace claimed that Coca-Cola -- the world's largest soft drinks company -- sells more than 100 billion plastic bottles every year. Single-use plastic bottles make up nearly 60% of the packaging produced by the company globally, the report says.The sculpture features seagulls regurgitating plastic and weighs 2.5 tonsCoca-Cola uses just 7% recycled material in their bottles, according to GreenpeaceThe company said recognized marine litter was a global problem
_-Cola has not disclosed how many plastic bottles it produces each year, but a previous Greenpeace study found that 530 billion plastic PET bottles were produced around the world in 2014, just over half of which were recycled. Casson told CNN she would like _-Cola to take the lead on producing more environmentally-friendly bottles, and hopes Greenpeace can work with the firm to reach that goal. It is impossible to know how many of these bottles end up in seas and oceans, but Greenpeace said _-Cola wasn't doing enough.

Greenpeace claimed _-Cola is also falling behind on its target to recycle the equivalent of 75% of the bottles and cans it sells in developed countries by 2020, despite their bottles being 100% recyclable.
