environmental and social issues which he expected to have a major impact on the global market economy in the 21st century, including oil depletion and climate change. He was a regular contributor to both Country Life magazine and BBC Radio 4's Today programme, and was published in Prospect and other journals, as well as in academic literature and popular newspapers. He was editor of The Countryside in 2097, published in 1997, and gave the third annual Feasta lecture in 2001, with his seminal Energy and the Common Purpose first published in 2005. David Fleming died in his sleep on 29 November 2010, while visiting a friend in Amsterdam. For over thirty years Fleming worked on the book that would pull together the various strands of his thinking, Lean Logic: A Dictionary for the Future and How to Survive It (formerly provisionally titled The Lean Economy). It was completed just before his death and posthumously published in 2016 by Chelsea Green Publishing, accompanied by a paperback version entitled Surviving the Future: Culture, Carnival and Capital in the Aftermath of the Market Economy. Views and Ideas He conceived and developed the idea of TEQs - the first and most widely studied model for the implementation of a carbon rationing system. His April 1999 article for Prospect magazine, "The next oil shock?", interpreted the International Energy Agency's 1998 report as predicting an impending global energy crisis. He later revealed that Fatih Birol – the future Chief Economist of the International Energy Agency – agreed to meet with him after reading the article, and confessed that "you are right… there are maybe six people in the world who understand this". Fleming had a long history with peak oil, having been part of the team who wrote the Ecology Party pamphlet The Reckoning in 1977, which discussed the issue and our need to rethink our use of energy. In his 2007 book The Lean Guide to Nuclear Energy: A Life-Cycle in Trouble, Fleming argued: Every stage in the nuclear process, except fission, produces carbon dioxide. As the richest ores are used up, emissions will rise. Shortages of uranium - and the lack of realistic alternatives - leading to interruptions in supply, could be expected to start in the middle years of the decade 2010–2019, and to deepen thereafter. It is essential that radioactive waste should be made safe and placed in permanent storage. High-level wastes,
