In a new analysis, leading climate social scientists argue that influential studies that attempt to quantify different countries’ “fair share” of climate action have put forward a biased and oversimplified view of what is primarily a political and ethical discussion.
The Perspective piece, “Ethical choices behind quantifications of fair contributions under the Paris Agreement,” published in Nature Climate Change comes as UN climate negotiators are expected to release new national plans for climate action ahead of climate negotiations this year in Glasgow, Scotland and defend them as “fair and ambitious”.
The piece evaluates a selection of recent effort-sharing studies to determine whether they are explicit about the ethical choices underlying their analysis or not. Reviewing sixteen studies that quantify equitable effort sharing between countries under the Paris Agreement, the authors find that nearly two thirds (ten studies) present themselves as neutral or value-free, despite being limited to a small and biased subset of ethical perspectives on effort-sharing that tend to favour wealthier countries.
Studies that incorrectly purport to be neutral and objective are not just misleading, they can even be harmful. In this case, they can set unrealistic expectations about what countries might be expected to contribute to a global climate effort. Even if it’s not intentional, one can imagine the problems caused by a body of literature with a consistent bias toward wealthier and against poorer countries.

In particular, ‘grandfathering’ of emissions, where countries argue their status as high emitters is a justification for continued high emissions, should not be included in equity assessments of global climate action. This is a key source of the systematic bias in favour of wealthier, higher emitting countries.
Other studies claim objectivity by averaging a spectrum of equity approaches, commonly choosing a subset that exclude important ethical concepts. For instance, when many analyses quantify a country’s capacity to allocate resources to a global climate effort, they routinely treat a dollar earned by a poor citizen as wholly equivalent to a dollar earned by a rich citizen.
One prominent assessment, the ‘Climate Action Tracker’ (CAT), generates a ‘Fair Share’ range of emissions allowances for each country that is widely used by media, academia, civil society and governments to assess countries’ mitigation ambition. The CAT method excludes a large number of studies for being statistical “outliers,” excluding whole categories of ethical positions.
Indicators that rank nations on their effort, like the influential Climate Action Tracker with its green, yellow and red symbols and "inadequate" type labels, actually hide some of these grandfathering indicators deep in their engine rooms. They say they're about equity, but there's still a systematic bias in favor of the biggest historical polluters. As we review efforts in the ‘global stocktake’ of the Paris Agreement, these kinds of indicators must be transparent. Otherwise, they are anti-equity.

“Studies should be explicit about the ethical and moral implications of their underlying assumptions, and equity assessments of countries’ climate action must be based on ethically defensible principles, such as responsibility, capacity and need” said Dr Kate Dooley, Research Fellow at the University of Melbourne and lead author of the study.
The authors propose new guidelines that emphasize transparency in communicating the ethical underpinnings of assessments of climate action and suggest guidelines for developing policy-relevant–but not ethically neutral–equity research:
