2. A very complex picture
Data from different studies indicate variable impact of a wine bottle.
Typically values sit around 3,3 kg CO2 eq./bottle
Values in the lower end still indicate 1.28 kg CO2 eq./bottle
Variability also due to wether different factors are considererd or not (e.g. delivery of bottles, purchase trip, etc)

3. Does closure matter?
Probably around 1%

4. Sustainability in synthetic closures
Novel technologies to reduce amounts of raw materials (plastics, ink, silicone)
Carbon emission strongly dependent on production of raw materials
Scrap reduction
Packaging
Production
Energy consumption also important
Plant and office lighting,
heating/cooling, etc
Water consumption
Renewable energy
Shipment
Recycling
Fault rate

5. Raw materials and packaging
16% reduction in
13% reduction in
22% reduction in
25% reduction in

6. Energy and water consumption
Very minor decrease but now 100% renewable
Ongoing decrease
18% reduction in

7. Overall evolution
2011
0.4 g CO2 eq./closure
2007
1.7 g CO2 eq./closure
1.3 g CO2 eq./closure
Raw materials
1.4 g CO2 eq./closure
Manufacturing
10.2 g CO2 eq./closure
Packaging
11.7 g CO2 eq./closure
Transport
11 g CO2 eq./closure
16 g CO2 eq./closure
Lowest reported for a wine bottle is 1.28 kg CO2 eq./closure

8. Recycling
In France
In the US

9. Other things to consider…
Viticulture and consumers transport have great impact
Lighter bottles could allow major improvements
Food miles deceiving, as transport mode is important (e.g. local truck transport can have higher impact than trans- continental ship transport)

10. Incidence of wine faults
What is the influence of consumers rejection of a faulty wine on life cycle assessments?
If we assume that rate of taint (e.g. cork taint) is 3.5% and that 35% of consumers will reject the tainted wine, then fault has a higher impact than the actual closure production
Sensory assessment of raw materials and finished products + consistent closure-to-closure and batch-to-batch performances major priority at Nomacorc
