Back at the start of May I was invited to speak at a business networking event run by Moral Fairground on the theme ‘The Unseen Cost of Travel’, alongside Intrepid Travel co-founder Geoff Manchester and Janine Hendry of Reho Travel. The invitation came about as a result of my posts here last year on the climate impacts of air travel. My brief was to cover the implications of carbon offsetting.
Here’s what I had to say, under the rough title ‘Carbon offsets or carbon penances? What a finite emission budget means for air travel and tourism futures.’
For a period pretty much identical to my own lifetime, travel for most rich-world citizens has effectively been synonymous with flying. In broader historical terms that’s a very small blip, and I’ll come back to that at the end in thinking about how those of us who take climate change seriously might deal with the dilemma that commercial aviation presents.

NASA released data last Monday indicating that the recent streak of monthly global temperature records has continued, with July 2016 being the hottest month since the modern temperature record commenced in 1880. Each month in 2016 has now been the hottest on record—in fact each of the last fifteen months running have now seen record maximum temperatures. The first seven months of 2016 averaged 1.3oC warmer than at the start of the record in the late nineteenth century. Arctic sea ice monitoring shows it at lowest recorded coverage for five out of the first six months of the year. 2016 is almost certainly on the way to being the hottest year on record.
It is now just seven months since announcement of the historic Paris Agreement on climate change mitigation. That agreement supposedly paves the way for keeping global temperature increase during this century ‘well below’ 2oC, with hopes even of a more ambitious restriction to 1.5oC. This is viewed—rather arbitrarily—as the threshold for a relatively ‘safe’ global climate. In light of the current warming trend though, that mitigation task, regarded only last December as achievable by signatories to the Paris Agreement, seems already to have slipped from reach.

The landscape of human history is scattered with the remains of societies that, at the peak of their prosperity, presumably seemed to their members no less resistant to decline than industrial society appears to most of us today. If this presumption is reasonable—if a general tendency to base expectations about the future of one’s society on present appearances is indeed a recurring theme in human experience across cultures and time—then we also know that present appearances may prove to be a rather unreliable guide to the future prospects for contemporary ways of life. Thanks to the work of historians and archaeologists, today we have access to detailed records of the life cycles of numerous past societies, and to diverse views on the processes by which they grew in size, influence and complexity before peaking and declining. While each societal story obviously differs significantly in its detail from others, and while different perspectives in relation to any one story emphasise particular factors, energetic considerations represent a recurring, foundational theme in both describing and making sense of the rise and fall of human societies. While they don’t determine a society’s prospects, principal energy sources and the technologies by which they’re harnessed are fundamentally important enabling and constraining factors in shaping a society’s past history and future prospects. Energetic considerations set the available budget for what a society can do, and bound the policy options for how it does what it does.
Industrial society is fossil-fueled. Around eighty percent of global total primary energy supply comes from coal, oil and natural gas. Just under six percent is from nuclear fission of uranium-based fuels. While there’s abundant uncertainty relating to resource sizes and economic reserves for each of these, there’s very little debate regarding their ultimately non-renewable status: the principal primary energy sources with which industrial society has arisen and that it continues to rely on can be treated as finite. Pick a long enough time horizon—and as Tom Murphy at Do the Math demonstrates, we don’t need to look out too far if anything like historical growth in energy use is assumed—and all futures for industrial society based on continued reliance on fossil fuels and uranium run up against their absolute physical limits. Long before such theoretical limits are reached, we’ll be contending with economic limits in the form of diminishing returns on effort, and ecological limits associated with Earth’s capacity to deal with the consequences of all of that fossil-fueled activity. Whichever way you care to look at it, we can safely say that long term futures for human societies will depend not on accumulated energy wealth from the past, but on present energy income. In this respect at the very least, the future for renewable energy looks rather bright indeed!
