EU Packaging Directive
targets:
EU climate targets:
Climate neutrality
by 2050
65% of packaging waste to
be recycled by 2025
50% of plastic and 75% of paper and cardboard
Conclusion:
Recycling targets alone not sufficient to meet the climate targets;
solutions related to e.g., packaging materials needed as well.
70% of packaging waste to be
recycled by 2030
55% of plastic and 85% of paper and
cardboard
The sustainability challenge
reducing GHG
emissions at least
55% below 1990
levels by 2030

5. Further development of LCA still needed
• Consistent approach covering all sectors
– Agriculture, forestry, land use, energy etc.
• Soil and biomass carbon stocks
• Biogenic carbon stored in products
• Indirect land use changes
• Handling side streams
• New impact categories
– Biodiversity
– Littering
