Humanity faces a number of daunting challenges in the 21st century. Climate change and socioeconomic injustice figure prominently on this list. When it comes to tackling these challenges, two possible strategies divide policy makers.
On the one hand, there are those who point out that addressing either of these problems on their own is a mammoth task, and that taking them on simultaneously is simply utopian. This view sometimes comes with a dose of optimism about technological solutions to climate change. On the other hand, an increasing number of voices argue that climate action can’t be separated from social justice. In particular, advocates of the latter position highlight the “triple inequality of climate change”: The global rich tend to pollute disproportionately and thus bear a heightened responsibility for climate change, the global poor are more vulnerable to its effects, and poor countries have fewer resources available for mitigation and adaptation. In political philosophy, we find a parallel divide between “isolationists” and “integrationists” respectively.
My point here will be to suggest that the case for integrationism is even stronger that even most of its ardent supporters acknowledge. To see why, consider the first of the inequalities mentioned in the previous paragraph. Studies suggest that, across countries, the top decile of polluters are responsible for about 50% of emissions, while the bottom 50% of polluters are only responsible for about 10% of emissions. Wealth strongly correlates with carbon-intensive activities – think everything from private jets and yachts, via mansion-size homes, to multiple trips by airplane per year or multiple cars in a single household.
