This paper examines the broad policy frameworks that can support the development and upscaling of Carbon Dioxide Removal (CDR) without diverting attention from ambitious greenhouse gas emissions reductions and, in particular, whether CDR can be supported by offsetting schemes. Setting separate emission reduction and removal targets may be a way to achieve this. The paper was funded by the Carnegie Climate Governance Initiative (C2G) , which is an initiative of the Carnegie Council for Ethics and International Affairs . Context and approach: The special report on the 1.5°C temperature limit by...

This summary report creates a framework to evaluate if a GST is successful and formulates recommendations for the design of the GST process. Please note that this is the executive summary of the full report that was published in advance to already feed into the negotiations at COP25. The main document will be provided subsequently. Key findings: The Paris Agreement combines collective goals with individual countries’ contributions. This hybrid approach does not guarantee that the individual contributions add up to what is required to meet the collective goals. The Paris Agreement therefore...

The independent Global Stocktake (iGST) seeks to increase the accuracy, transparency, accountability, and relevance of the official Global Stocktake benchmarking process by bringing together independent researchers and advocates. In this paper, build on previous work, we aim to identify knowledge gaps as well as potential areas of focus for a successful GST to take place. Executive summary: The Paris Agreement includes a cycle of ambition. Each five years, starting in 2023, a Global Stocktake (GST) analyses the global situation and provides information for countries to prepare updated...

Achieving the collective goal of limiting warming to below 2 °C or 1.5 °C compared to pre-industrial levels requires a transition towards a fully decarbonized world. Annual greenhouse gas emissions on such a path in 2025 or 2030 can be allocated to individual countries using a variety of allocation schemes. We reanalyse the IPCC literature allocation database and provide country-level details for three approaches. At this stage, however, it seems utopian to assume that the international community will agree on a single allocation scheme. Here, we investigate an approach that involves a major...
