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:
