How much does your morning glass of orange juice contribute to global warming?Interesting to see where in the life cycle most of the CO2 is emitted. Looks like fertilizer use is the largest portion accounting for 35% of the total.
PepsiCo finally came up with a number: the equivalent of 3.75 pounds of carbon dioxide are emitted to the atmosphere for each half-gallon carton of orange juice.
As was the case with Walkers, Tropicana hired an outside auditor, the Carbon Trust, to review its calculations and certify its footprint.
Making orange juice is relatively straightforward: the oranges are picked by hand, trucked to the plant, squeezed, pasteurized and packed into cartons and shipped by train to distribution points around the country.
Growing the oranges accounted for a larger share — about a third — than PepsiCo had expected, almost entirely because of the production and application of fertilizer.
