"Plastic contamination threatens marine life, tourism, fisheries and businesses," the eleventh edition of the UN Environment Programme (UNEP) Year Book, which updates 10 issues previously highlighted over the past decade and provides mitigation steps for each, said.
"Plastics undoubtedly play a crucial role in modern life, but the environmental impacts of the way we use them cannot be ignored," UNEP Executive Director Achim Steiner said.
Making a case for managing and disclosing plastic use in the consumer goods industry, the report added, "Over 30 per cent of the natural capital costs are due to greenhouse gas emissions from raw material extraction and processing. Marine pollution is the largest downstream cost, with the USD 13 billion figure most likely a significant underestimate."
Calculating the negative financial impact of issues such as marine environment or air pollution caused by incinerating plastic, the report said that the overall natural capital cost in the consumer goods sector each year is USD 75 billion.

Some of this material sinks to the ocean floor, while some floats and can travel over great distances on ocean currents - polluting shorelines and accumulating in massive mid-ocean gyres.
"These reports show that reducing, recycling and redesigning products that use plastics can bring multiple green economy benefits: from reducing economic damage to marine ecosystems and the tourism and fisheries industries - vital for many developing countries - to bringing savings and opportunities for innovation to companies while reducing reputational risks," Steiner said.
