In the global effort to limit climate change and reduce greenhouse gas emissions (GHGs), the energy and transportation sectors are the most obvious targets, but perhaps not be the biggest. Consider the food business. Agriculture alone – not including the sizable food processing industry — produces up to 35% of the world’s greenhouse gas emissions (and uses 70% of the water).

By some estimates, humanity may need to produce as much food in the next 40 years as it did in the last 8,000. And that can’t happen if we don’t get the carbon and water footprint of agriculture under control. With the stakes so high, it’s welcome news that food giants are getting serious about emissions.
