Vast changes in the global food industry are critically required. A forthcoming report (due on June 5) will show that 43 to 57% of greenhouse gas emissions caused by humans are associated with modern practices of production, packaging and distribution of the world’s food supply. That is one good reason for making dramatic changes, along with many other reasons discussed by the authors of this article, published by Thomson Reuters Foundation. “While the current system makes food cheaper and more accessible, the unaccounted for damage on both the environment and human health comes at a far greater cost down the line.”

A three-day conference in Sweden covered all of the latest thinking about the need and potential for large-scale negative emissions programs. Carbon Brief has a summary report of the entire event, showing how much study is being devoted to moving in this direction. There are plenty of ideas put forth but no sign of any imminent breakthroughs to get excited about.
