Equity is the Missing Key for Climate Roadmaps

In March of 2017, Johan Rockström, the author of Big World, Small Planet: Abundance within Planetary Boundaries, along with a extremely high-tone list of co-authors, published A roadmap for rapid decarbonization in Science.  In it they propose a “roadmap” of escalating actions from now until 2050, designed to keep the average global temperature change under 2° Celsius, with some chance of limiting it to 1.5°C.

It’s an important piece, and its bottom line, as scientist and critic Kevin Anderson put it, is that the Rockström et. al. have “upped the ante.” In particular, they have translated carbon-budget science into a specific, decade-by-decade plan for a greatly accelerated global technological transition, driving net global CO2 emissions down to a near-zero level in 2050 – a mere 33 years. This type of planning is crucial as policy makers everywhere wrestle with the immense challenges of meeting the collective goals they agreed to in the Paris Agreement. However, a key element is missing from Rockström’s roadmap: equity.  More specifically, they have nothing to say about the fair sharing of climate action among countries. The bottom line here is that we can’t hope to succeed unless this challenge, too, is taken up, so its omission from Rockström’s paper is unfortunate.

Kelly Stone, a senior policy analyst at Action Aid USA, and I replied in the Huffington Post, in a piece called Equity is the Missing Key for Climate Roadmaps.  Among other things, we said that:

“Morally, there’s no question that developed countries must take the lead, and also assist the poor in the extremely challenging decades that lie ahead. Developed countries including the United States have been emitting far more carbon for far longer than developing countries, and they are, moreover, the homes of most of the world’s wealthy. The top-line message here could not be more clear, for the richest 10% of the world’s people produce half of Earth’s fossil-fuel emissions, while the poorest half contribute a mere 10%. This is the essential background without which it’s impossible to understand the position today, in which we’ve used up essentially the entire global carbon budget, and, to note the sharpest part of the challenge, developing countries face an urgent need to leapfrog to renewable energy even as many of their citizens still lack basic energy access, let alone proper health and education systems. Even worse, people in the global south – especially the poorest – are already feeling the impacts of climate crises they did nothing to create. Asking them to take to a roadmap that makes no provision for such facts is simply wrong.

Nor is climate equity just a moral challenge. There are strong instrumental reasons to believe that, unless we put the equity challenge front and center, there’s little hope of following any road as difficult as the one that Rockstrom and his co-authors have laid out. The bottom line here is that, given the emergency situation we’re now facing, developing countries must mobilize on a scale that far overwhelms their capacity to act alone, and they must do so even as rising climate impacts force them to prioritize adaptation. They cannot possibly meet these challenges without support from developed countries, and even in the short term it’s difficult for them to lay the necessary plans without some modicum of confidence that such support will be forthcoming.”
