Doing better than 2008, but not much improvement in the last year
The Port of San Diego recently released its Green Port Year In Review results for the 2012-2013 fiscal year, celebrating significant reductions in water and electricity use and in the carbon footprint of Port activities. Little, however, appears to have changed in the last year.
Water use has decreased nearly 40 percent from when the Port implemented its environmental program in 2008, from nearly 225 million gallons to just over 125 million. Numbers from last year actually rose slightly from 2011-2012, however, due to “decreased wintertime precipitation from last year and construction activities on the terminal.”
Likewise, the overall carbon footprint from Port activities is down nine percent from 2008, though it’s up slightly over year-ago calculations because of “added harbor craft training for Harbor Police Officers.”
Energy use is down 12 percent from 2012, but largely flat over the last three years.
The Port says its installation of shore power systems, which allow cruise ships to power down their diesel generators while docked, has reduced emissions by 19 tons, or the equivalent pollution of 400 cars’ average operation over a year. The conversion of 404,000 square feet of landscaping (over nine acres) has been converted to “waterwise” use.
“The ultimate goal of the program is to achieve long-term environmental, societal, and economic benefits through resource conservation, waste reduction, and pollution prevention,” says Cody Hooven, the senior environmental specialist and manager of the Green Port program.
