Fair Share Now / Traffic Light Assessment
The FairShareNow.org campaign for climate justice launched by the 58 countries of the Climate Vulnerable Forum is based on our analysis (under review with Nature Communications).
This platform contains the Traffic Light Assessment Report 2023 where the CVF explains how these results reflect key equity considerations of the Paris Agreement.
The results presented here are based on a study under review in Nature Communications (see below) that challenges existing models allocating fair emissions trajectories to countries and offers to address a bias found in the literature that favours large emitters.
Paris Equity Check
The Paris-Equity Check.org is an interactive online tool that provides a fairness and ambition assessment of countries’ emissions pledges through two analyses reflecting the results of two peer-reviewed studies in Nature Climate Change and Nature Communications (see below).
The first analyses (Equity Map) compares countries’ pledges to emissions trajectories based on various interpretations of fairness based on the philosophical and legal literature.
The second assesses (Pledged Warming Map) the ambition of countries’ pledges against a combination of equity-based emissions allocations seeking to reflect the Paris Agreement equity principle.
Scientific studies
On the bias in current ambition assessment of countries’ pledges and the importance of immediate fairness
Effects of emissions allocations and ambition assessments immediately based on equity, Robiou du Pont, Dekker, van Vuuren, Schaeffer. Under review with Nature Communications.
This paper reviews existing models allocating fair emissions trajectories to countries and offers to address a bias found in the literature that favours large emitters.
Ambition assessment of countries’ emissions pledges and their global warming alignment
Warming assessment of the bottom-up Paris Agreement emissions pledges, Robiou du Pont, Meinshausen. Nature Communications, 2018. Ranked #8 in the Nature Communications "Top 50: Earth and Planetary Sciences".
This paper assesses the ambition of countries’ pledges against a combination of equity-based emissions allocations seeking to reflect the Paris Agreement equity principle. It provides the first ambition metric relating pledged emissions targets with global warming alignment. This paper relies on a bottom-up approach of equity where each country can apply their own approach of equity, reflecting the Paris Agreement architecture.
Modelling national emissions trajectories that reflect a range of equity principles, some reflecting the Paris Agreement
Equitable mitigation to achieve the Paris Agreement goals, Robiou du Pont, Jeffery, Gütschow, Rogelj, Christoff, Meinshausen. Nature Climate Change, 2017. Accessible here.
This paper compares countries’ pledges to emissions trajectories based on various interpretations of fairness based on the philosophical and legal literature.
Operationalising competing equity principles to mitigate global warming
PhD thesis: Climate justice: can we agree to disagree? Operationalising competing equity principles to mitigate global warming
This PhD thesis and its published articles explore how quantitative modelling can apply principles of distributive justice to derive emissions allocations for countries to align with a collective climate goal and the equity principles of the United Nations framework.
This thesis includes some of the scientific articles presented above and explains the conceptual linkages between the fairness principles from the literature on distributive justice, and their relevance to interpret national obligations under international agreements, such as the Paris Agreement.
