Last week, 195 nations approved a global climate change accord at the COP-21 Paris Climate Conference, committing to lowering greenhouse gas emissions to stave off the most drastic effects of climate change. Here in America, food manufacturing companies are already taking historic steps to reach new emissions reduction targets and support sustainability. Climate change poses a major threat to global food security. The U.S. Department of Agriculture (USDA) recently released a new report on the risks that climate change poses to global food security, including the challenges facing food manufacturers in adapting to changing climate conditions. Companies from General Mills and Walmart are taking steps in food manufacturing to reduce greenhouse gas emissions and sustainably source key ingredients.
