Released at COP29, a new report from the Center for Global Sustainability outlines high-ambition pathways for major emitting countries, suggesting a potential 35% reduction in greenhouse gas emissions by 2035, compared to just 7% by 2030 under current NDCs.

The international community has an important window in which countries can advance their climate ambitions and limit global temperature rise. Over the coming months, the parties to the Paris Agreement will submit their Nationally Determined Contributions (NDCs), establishing their climate targets for the years ahead. The NDC process empowers individual countries to drive their climate policies and actions forward within their own country’s conditions and priorities. At the same time, the NDC process provides a transparent platform for open assessment and discussion. While the Paris NDC cycle has proven value, national targets vary substantially in type, coverage, level of stringency, and room for uncertainty.  

This new report, entitled Enhancing Global Ambition for 2035: Assessment of High-Ambition Country Pathways, establishes several approaches for meeting global and national climate targets. A bottom-up approach with in-depth country assessments allows a better understanding of near-term practicality, especially in the pursuit of high-ambition climate goals. The CGS analysis highlights how non-state actors can contribute to enhanced ambition and implementation across different sectors and types of greenhouse gas (GHG) emissions, especially in key priority areas. In addition, non-state actors (states/provinces, cities, businesses, etc.) have demonstrated increased leadership in policy development and implementation that can advance large emissions reductions in the future.  

Using an open-source, field-leading global integrated assessment model, CGS researchers examined the state of global climate action as well as the efforts of ten major GHG-emitting countries. The report lays out high-ambition, economy-wide pathways for emission reductions through 2035 and beyond, identifying policy opportunities across sectors for rapid emissions reductions and assessing aggregate global emissions and temperature outcomes.
