What is a country's fair share of carbon mitigation efforts if we are to keep global warming below 2C?

Climate Equity Scorecards

US-based EcoEquity, working with researchers from the Stockholm Environment Institute, has spent years establishing the Greenhouse Development Rights framework as a uniquely promising approach to fair-shares global burden sharing.

After Copenhagen, Cancun and Durban, the need for such a "reference framework” - one by which national pledges and actions can be compared and judged - has greatly increased.  Thus, a new version of Greenhouse Development Rights is under development.

Minor Foundation is funding a project that will communicate these fair shares through Climate Equity Scorecards. These are designed to help campaigners around the world show their countries what their "fair share” of the global climate effort actually is.

This is the announcement of the publication:

We’re pleased to (finally) announce the official debut of the <http://www.gdrights.org/calculator/> Climate Equity Reference Calculator and the <http://www.gdrights.org/scorecard/> Climate Equity Pledge Scorecard. The Equity Reference Calculator is a web application that implements a very general equity reference framework. It allows users to specify a level of global ambition (they can choose a "Strong 2°C pathway,” a "Weak 2°C” pathway, or a "G8 pathway – see <http://gdrights.org/gdrs-scorecard-calculator-information/mitig-path-overvi ew/> here for details) and then to specify their own preferred interpretation of national responsibility and capacity for climate action. These specifications are then used to define a "responsibility and capacity index,” which in turn is used to determine each country’s fair share of the global effort.

This Equity Reference Calculator, is thus intended to model the user’s preferred approach to global effort sharing. The user’s options are quite flexible (see the "Equity Settings” panel on the left) and we intend to make them more flexible in the future. Our plan is to support a very wide range of plausible approaches to the Convention’s core equity principles.

The Pledge Scorecard, for its part, is a web application specifically to quickly assess a country’s pledge. It is integrated with the Calculator, but it can also be used on its own, for example by users who want to be confronted with fewer options and less detail. The Scorecard’s user interface allows all the core "Equity Settings” to be changed, but for the full range of settings (e.g., if you want to switch from production-based to consumption-based emissions accounting) you need to go to the Calculator.

There’s still more that will be done to make these tools yet more general, more usable, and more useful to civil society and to Parties. We look forward to feedback that will help us to do so. But we believe that these tools are able in their present state to support a more robust discussion of climate equity, one that focuses and clarifies the discussion of fair-shares effort sharing and the assessment of national pledges. So take a look.

The <http://gdrights.org/Calculator-about/> About the Calculator and Scorecard page is probably the best place to start. Both tools contain good help systems, and contains links to a decent quick guide, which provides a basic tour and points out many of the key issues. There’s also a great deal of detailed technical documentation for those who want it.

In hope
