Working together, the Stockholm Environment Institute and EcoEquity (after having jointly abandoned the Per Capita Plus project) developed and launched the Greenhouse Development Rights (GDRs) framework. This was a major event in their collaboration, and entirely redefined it.
In late 2006, Paul Baer, by way of consulting he was doing for the UK’s Institute for Public Policy Research, influenced the International Climate Change Taskforce to endorse a long-term climate stabilization target of 400 ppm CO2-equivalent. This is, as far as we know, the first time this honest but extremely demanding target was publicly tied to the 2°C threshold.
In 2002, EcoEquity joined forces with Steve Bernow (now deceased) and Sivan Kartha, both of which were at that time scientists at the Boston-based Tellus Institute. Together, we worked to develop the Contraction and Convergence approach to global climate justice into a more robust system capable of accounting for both per-capita emissions rights and varying national circumstances. This became known as the “Per Capita Plus” project.
