CSE has been well known for influencing the design of international climate policy since well before such policy was enshrined in formal institutions - whether it is the landmark paper released in 1991 by Sunita Narain and Anil Agarwal, calling for a decolonisation of carbon budget accounting, or CSE’s commentary on every UN climate meeting since 1992. CSE has led the discourse in climate policy for over three decades advocating for equity, the principle of Common but Differentiated Responsibilities, and investing in resilient economies for the poor.
The Climate Change and Green Economy Programme is committed to championing the study of the most pressing climate issues relevant for the Global South. CSE’s publications on climate-critical topics, its presence at UNFCCC proceedings such as COP summits and Subsidiary Body meetings, public outreach and advocacy, media engagement, and training programmes are designed to create multipliers in society for climate action.
