In the container yard, Dole reduced its use of fuel by 33% between 2007 and 2009. Results were achieved by:
- Revising and implementing control mechanisms (i.e. automatic “turn-off” devices) for container handling equipment.
- Establishing fuel quotas.
- Implementing reduction goals.
- Extending the use of vortex valves from 50 gensets to 150 in Costa Rica.
- Additional reductions will be achieved in the coming years through continued use of fuel monitoring gauges and GPS tracking systems in the genset equipment. This practice will measure precise fuel use, help avoid fuel misuse and should also facilitate route optimization.
In the container yard and container transportation, Dole reduced its greenhouse gas emissions by over 90% in five years due to:
- More effective preventative Maintenance and Repair programs.
- Replacement of refrigeration units for more modern equipment. Action began in 2005 when Dole eliminated CFCs from the container fleet. In late 2009, to the Company launched a plan for eliminating HCFC refrigerants from container fleet – mission completed by May 2010, making Dole’s container fleet 100% HFC. This change contributed to a decrease in carbon dioxide equivalents (CO2e) emissions by 90% between 2004 and 2010 (For more information on CO2e and Dole’s Carbon Footprint, see “Background Information“).
- Testing of newer units that feature superior insulation and compressor systems, for achieving even better results.
Measurement and certification of the CO2e emissions of our vessels. There was a 2% reduction in footprint per kilo of fruit shipped from 2008 to 2009.
- In addition:
- The hulls of Dole ships are painted with custom coatings designed to decrease friction and improve performance.
- Dole is studying alternatives for “cold ironing.” This initiative is aimed at using electricity from land sources to turn the ships’ engines off as a way to diminish air pollution in populated areas, such as Southern California.
