Recent research explores how countries can be held accountable for emissions in the context of the 1.5°C climate target. Utilizing the principle of Common But Differentiated Responsibility and Respective Capabilities (CBDR-RC), the study introduces an indicator of “additional carbon accountability.” This framework reveals the need for enhanced climate commitments from major emitters, particularly the EU, China, and the US, to effectively mitigate climate change and limit warming.
In response to claims of the demise of the 1.5°C climate target, recent research examines how nations can be held accountable for emissions. The study develops a framework based on the principle of Common But Differentiated Responsibility and Respective Capabilities (CBDR-RC). This principle differentiates countries’ obligations based on historical emissions and their abilities to act, ultimately assigning greater accountability to those with larger carbon footprints.
The article introduces the indicator of “additional carbon accountability” to assess countries’ responsibilities beyond their current climate commitments. For instance, the study indicates that achieving the 1.5°C target will require the EU, China, and the US, among others, to enhance their mitigation efforts significantly. By holding these countries to their historical emissions, the study insists on more assertive carbon dioxide removal measures, which include afforestation and advanced technologies such as direct air capture.
Additionally, the study identifies substantial gaps between current emissions targets and what is required to meet the 1.5°C goal. It estimates that the EU must mitigate or remove an extra 48 billion tonnes of carbon dioxide, while China and the US face accountability of 150 billion tonnes and 167 billion tonnes respectively. These figures underscore the urgency for nations to reassess their commitment levels in the fight against climate change.
The study critiques high-income countries for their slow progress and stresses the need for a shift from merely achieving existing targets to addressing their historical emissions debts. It notes that many upper-middle-income countries also project high future emissions, indicating a complex global landscape in which accountability must be equally shared among varied economies.
Despite the lack of international consensus on enforcing the fairness principles outlined in the Paris Agreement, the proposed accountability framework provides clarity on which nations must act. This approach facilitates a focus on specific national responsibilities rather than a generalized divide between developed and developing nations regarding climate financing.
An analysis of the economic implications of this accountability indicates that significant investment in carbon reduction efforts would be necessary for countries like Iran and Russia, with projected accountability costs exceeding their GDPs. This highlights a pressing challenge as nations grapple with the financial realities of adhering to their emissions responsibilities.
While the political will among many high-income nations appears to be lacking, the article emphasizes the importance of incremental changes in targets and accountability measures. It leaves open the possibility that current political climates may shift, increasing the urgency to act. As every degree of warming has its consequences, the proposed accountability framework could instigate stronger commitments from countries responsible for substantial emissions.
The research emphasizes the necessity for nations to enhance their climate targets and accountability in order to achieve the 1.5°C climate goal. By clearly delineating responsibilities based on historical emissions and future projections, the framework encourages more ambitious policy adjustments. Although significant political challenges exist, increasing pressure for accountability may foster greater compliance among high-emission countries and drive essential climate action.
