Creating a Sustainable Food System with Reduced Greenhouse Gas Emissions

Professor of Applied Economics

us food system produces 20 of ghg emissions
US Food System Produces 20% of GHG Emissions
  • From farm to waste disposal.
  • Majority is CO2 from processing & transportation.
  • Methane, mainly from ruminants and decomposition of food waste.
  • 23X the effect of CO2 on global warming.
  • Nitrous oxide, from nitrogen fertilizer.
  • 296X the effect of CO2.
global food system
Global Food System
  • Responsible for 30% of GHG emissions.
  • Large Ag. sectors with smaller industrial and service sectors, and low household energy use, especially in developing countries.
  • Paddy rice cultivation is a major source of methane.
  • As fertilizer and other organic matter decompose under water (anaerobic).
american diet ghg s
American Diet & GHG’s
  • Typical diet has large amounts of meat, processed food, and products shipped long distances.
  • Average food item travels 1,500 miles.
  • Typical diet produces as much or more GHG’s as driving an average mid-size car.
continued
continued
  • Typical American diet produces 2.8o tons of CO2 per year.
  • Various motor vehicles driven average number of miles (8,332 miles per year; 63% highway).
  • Prius: 1.19 tons of CO2
  • Camry: 2.24 tons
  • Suburban: 4.76 tons.
energy efficiency of representative foods
Energy Efficiency of Representative Foods*
  • Beef (grain feed) 6.4
  • Tuna 5.8
  • Milk 20.6
  • Apples 110.0
  • Potatoes 123.8
  • Soybeans 415.0
  • * Percentage of fossil fuel energy calories retrieved as edible calories
reducing ghg emissioms from us food system
Reducing GHG Emissioms from US Food System
  • Reduce the consumption of red meat, especially from grain-fed cattle, and dairy products.
  • Consume more foods grown locally and in season.
  • Eliminate bottled water or at least switch to locally bottled water.
  • Reduce food waste.
  • Eliminate any product that is shipped by air freight.
