ENABLING AND LEVERAGING CLIMATE ACTION TOWARDS NET-ZERO EMISSIONS

为了实现《巴黎协定》的目标，温室气体排放需要在2050年左右减少到净零。然而，目前的政策仍不足以实现这一目标，各国的净零承诺通常缺乏如何实现这些目标的具体路线图。ELEVATE旨在建立强有力的科学认识，以加强国家自主贡献和当前的气候政策，实现净零排放。为此，ELEVATE汇集了一个独特的多学科联盟，由领先的国际和国家建模团队、气候政策专家和社会科学家组成。该联盟旨在与决策者直接互动，以确定信息差距和有吸引力的政策，从而提高知识库的可用性并促进相互学习。在此基础上，该联盟将系统地评估全球和国家一级的国家自主贡献和政策，以确定当前的进展和良好做法政策。随后，ELEVATE将研究与部门行动、国际气候政策以及与正义和可持续发展的关系相关的一系列关键促成因素，这些因素可以用来加强行动。这使得新一代的全球和国家缓解情景得以实现，探索加强世界各国气候政策和支持净零目标的可能性。我们评估了制定净零目标的不同方法的影响以及气候不确定性的影响。成果包括关于如何加强政策以实现净零目标的详细途径和里程碑。ELEVATE大大超越了最先进的技术：1)将社会科学纳入分析的各个方面，提供了对实施和可行性相关问题的显著改进的见解；2)详细关注部门行动；3)利益相关者互动；4)全球和国家团队之间在净零排放情景方面的直接合作。

To implement the Paris Agreement's goals, greenhouse gas emissions need to be reduced to net-zero around 2050. However, current policies are still insufficient to reach this target and net-zero promises by countries are generally lacking concrete roadmaps how to reach them. ELEVATE aims to create a robust scientific understanding required to strengthen NDCs and current climate policies towards reaching net-zero emissions. For this, ELEVATE brings together a unique multidisciplinary consortium of leading international and national modelling teams, climate policy experts and social scientists. The consortium aims to interact directly with policymakers to define information gaps and attractive policies, thus enhancing usability of the knowledge base and stimulating mutual learning. Based on this, the consortium will systematically assess NDCs and policies at the global and national levels to identify current progress and good practice policies. Subsequently, ELEVATE will look into a range of critical enabling factors related to sectoral action, international climate policy and the relationship with justice and sustainable development that can be leveraged to strengthen action. This allows a new generation of global and national mitigation scenarios, exploring the possibility of strengthening climate policies in countries worldwide and support net-zero goals. We assess the impact of different ways to formulate net-zero goals and the impact of climate uncertainty. Outcomes include detailed pathways and milestones on how policies can be strengthened to achieving net-zero goals. ELEVATE goes significantly beyond the state-of-the-art by 1) the inclusion of social sciences in all aspects of the analysis providing significantly improved insights into issues related to implementation and feasibility, 2) the detailed focus on sectoral action, 3) the stakeholder interaction and 4) the direct collaboration between the global and national teams on net-zero emission scenarios.
