Notes and Assumptions for Carbon Footprint Calculator
1. Carbon Footprint for the Manufacture of Natural Corks |
| |
Model Based on Estimates from:
de Jesus, C., “ Preliminary figures from LCA assessment by PricewaterhouseCoopers” Cambio Climático y Vino, Barcelona, February 2008 Carbon Footprint for Cork = 4.8g/cork
Other Estimates: Forgues, C., Carbon Appraisal of the Different Methods Used for Closing Still Wines, Australian & New Zealand Grapegrower & Winemaker, September 2007 (No. 524) Carbon Footprint for Cork = 8.0 tons/million pieces (7.25 g/cork)
Walker,L., Cork and Sustainability, Wines & Vines, August 2007, p. 64 Carbon Footprint for Cork = 3.27 tons/million pieces (2.96 g/cork)
Model does not include capsule or transportation to specific markets.

2. Carbon Footprint for the Manufacture of Aluminum Screwcaps |
| |
Model Based on Estimates from:
de Jesus, C., “ Preliminary figures from LCA assessment by PricewaterhouseCoopers” Cambio Climático y Vino, Barcelona, February 2008 Carbon Footprint for Screwcaps = 37g/cap
Other Estimates: Forgues, C., Carbon Appraisal of the Different Methods Used for Closing Still Wines, Australian & New Zealand Grapegrower & Winemaker, September 2007 (No. 524) Carbon Footprint for Screwcaps = 52 tons/million pieces (47.14 g/cap)
Walker,L., Cork and Sustainability, Wines & Vines, August 2007, p. 64 Carbon Footprint for Screwcaps = 14.37 tons/million pieces (12.95 g/cap)
Model does not include liners or transportation to specific markets.

3. Carbon Footprint for the Manufacture of Synthetic Stoppers |
|
Model Based on Estimates from:
de Jesus, C., “ Preliminary figures from LCA assessment by PricewaterhouseCoopers” Cambio Climático y Vino, Barcelona, February 2008 Carbon Footprint for Synthetics = 15.4 g/stoppercap
Other Estimates: No other printed estimates were found but this estimate was corroberated by representatives of the leading manufacturer of Synthetic stoppers.
Model does not include capsule or transportation to specific markets.

4. Carbon Offset from Contribution of the Cork Forest |
|
Model Based on Estimates from:
de Jesus, C., “ Preliminary figures from LCA assessment by PricewaterhouseCoopers” Cambio Climático y Vino, Barcelona, February 2008 Carbon Footprint for Cork = -118.5 g/stoppercap
Estimate is based on a study carried out in Portugal by the Portuguese School of Agronomy (ISA), intended to measure the annual liquid sequestration of carbon, including the analysis of a southern cork oak forest, which presented an ELP of 179 g C/m2 in 2006.

5. Carbon Footprint Conversion to Mileage |
|
Model Based on Estimates from:
http://www.carbonify.com/carbon-calculator.htm Carbon footprint for an automobile getting 21mpg is .55 tons/1000 miles driven = 1,818 miles per ton or CO2
