Paris: The End of the Beginning

Will Paris be a success or a failure? It will be both. The real question is whether it opens the way to a new future of justice and ambition.

This essay was first published in the Earth Island Journal

As I write this, the United Nations climate conference is only weeks away. And now, of course, it will take place in an atmosphere of mourning, and crisis, and war. Beyond this change of tone, what difference will the November 13 attacks make on the outcome of the negotiations? It is impossible to say, though it’s not too much to hope for heightened clarity, and seriousness, and resolve. This is a time to attend to the future – on this, at least, we should be able to agree.

The essay below was finished before the attacks. I’ve changed only these opening words, which already said that the stakes were high. This has not changed. Nor has my overall claim, that while the negotiations are not going well, they’re not going badly either, and that in any case they must be judged in realist terms.

Fair Shares: A Civil Society Equity Review of INDCs

Cover image - smallerAn unprecedentedly broad and diverse coalition of global civil society organizations and social movements (see the list here) has just released a joint assessment of the national pledges of action (called “INDCs” in UN lingo) that are being submitted in the global climate negotiations.

This assessment was done with eyes towards both adequacy and equity.  Fundamentally, it asks what the INDCs add up to in relation to a 1.5°C / 2°C degree goal, and if each country is pledging to do its fair share of the necessary mitigation action, based on its historical emissions and its capacity to act.  When it comes to public mitigation finance, adaptation, and loss & damage, the assessment restricts itself to estimating total global needs.

Technically, the Civil Society Review draws upon the analysis and modeling of the Climate Equity Reference Project, which is, of course, strongly associated with this site. However, it is done with respect to specific range of equity settings, one which defined the agreement within the coalition and, notably, one which is narrower than the range of settings supported by the Climate Equity Reference Calculator.  On the adequacy side, it is referenced to a challenging global mitigation pathway that represent a widely used distillation of the most stringent category of pathways in the IPCC scenario database.

There are many details, most of which are explained in the report.  The key point however, and please keep this in mind, is that the review does not argue that countries should only do their fair shares.   Rather, it seeks to identify which countries are offering to do their fair share, which need to do more to meet their fair share, and which must be supported to do even more — sometimes much more — than their fair share if the world is to reach a below 2°C or even 1.5°C pathway.

The full report, the summary report, and the list of supporting organizations can all be found at  This site also contains a form by which your organization can add its name to the list of supporters, if it wishes to do so.

Piketty (and Chancel) on Climate Equity

Remember Thomas Piketty, recently famous for a book named Capital in the Twenty-First Century? Well the very same Thomas Piketty (Paris School of Economics), together with Lucas Chancel (IDDRI, Paris School of Economics) has just published a paper called Trends in the global inequality of carbon emissions (1998-2013) & prospects for an equitable adaptation fund. And a fascinating paper it is!

Trends in the global inequality of carbon emissions is a call for a global progressive carbon consumption tax (with a 0% marginal rate for those below a key threshold) that is designed to provide $150 billion a year for the global adaptation fund (a key climate fund that, while formally established, is woefully underfunded).

The crucial thing here is that Chancel / Piketty explicitly seek a globally progressive tax on individuals rather than countries. They do this for a number of reasons, but first among them is the judgement that inequality between people has (since 2013) become a greater source of emissions inequity than inequality between countries:

“Our estimates also show that within-country inequality in CO2e emissions matters more and more to explain the global dispersion of CO2e emissions. In 1998, one third of global CO2e emissions inequality was accounted for by inequality within countries. Today, within-country inequality makes up 50% of the global dispersion of CO2e emissions. It is then crucial to focus on high individual emitters rather than high emitting countries.”
