This study, building on a previous study conducted by Prognos in 2008, highlights the important contributions by the waste management sector to the EU climate objectives, accounting for avoided emissions for 10 selected waste streams for EU27+UK, based on available statistical data. 9 material waste streams were considered (Paper, Glass, Plastics, Ferrous metals, Aluminium, Wood, Textiles, Waste tyres, Biowaste) plus one stream representing residual waste and Waste Derived Fuel, which includes non-separately collected waste and rejects from waste treatment facilities. The 10 selected waste streams accounts in total 505 Mt, correspondent to approx. 19 % of the total waste generated in EU27+UK in 2018. Potential CO2 emission reductions are examined against the background of recent revisions of the EU waste legislation. The study explores the potential contribution this legislation and the waste management industry could have to reaching the ambition of climate neutrality by 2050 set out in the European Green Deal, as well as the effect of more ambitious targets. https://ie-rm.org/services/new-study-european-waste-management-sector-shows-significant-co2-reduction-potential-for-10-waste-streams/
