Reducing animal product consumption is a necessary action to mitigate climate change and other environmental issues. We tested and compared the effectiveness of an individual and a social app-based 30-day challenge in reducing animal product consumption. Through a pre-registered field randomized controlled trial (n = 1213), we find both conditions reduced animal product consumption by 16–17% compared to the control group, with a lasting effect only for the social treatment (encouragement to involve family and friends) 3 months after the intervention. The effects were largest for meat consumption and those who consumed meat at the baseline. Additionally, associated greenhouse gas emissions decreased by 21–24% and are still significantly reduced 3 months after both interventions, with a larger effect for the social treatment. Our findings suggest that app-based animal product-free challenges are a cost-effective way (~€13–25 per tCO2-eq assuming a 1-year lasting effect) to translate intentions into lasting dietary change, especially when involving the social environment and targeting meat eaters.

Cross-national research has found that the decarbonization effect of renewable energy development is relatively weak in high-income nations. It is crucial to identify effective points of intervention to enhance renewables’ decarbonization effect. Using a multidimensional analytical framework, this study examines whether certain structural components of high-income nations’ CO2 emissions are particularly susceptible to barriers to decarbonization and therefore are less effectively mitigated by renewable energy development. Analyzing a panel dataset covering 33 high-income nations from 1996 to 2019, I identify a pattern of uneven decarbonization. Renewable energy development has mitigated production-based emissions with increasing effectiveness over time; however, the mitigation effect has been largely confined to emissions from domestic-oriented supply chain activities. Meanwhile, renewables’ inability to mitigate emissions embodied in exports and direct end-user emissions has largely persisted over time. Additionally, developing renewable energy has not spurred growth in emissions in imports, indicating that it has not intensified carbon leakage.

Climate risk assessments are crucial in quantifying and communicating risks in a clear and concise manner. In light of the rapidly proceeding climatic changes, there is a growing need for a more comprehensive integration and a more effective overview of available and relevant data that go into these assessments, particularly on the temporal and spatial dynamics of risk. In this paper, we describe the advantages, challenges and opportunities for increasing the accessibility of temporal and spatial data needed to support climate risk assessments through the development of an Intergovernmental Panel on Climate Change (IPCC) Atlas, integrated across IPCC Working Groups. We propose that using a climate risk framework to organise this Atlas will result in a more practical resource for understanding and informing risk assessments undertaken by the IPCC, and also make methodologies and results more accessible to a wider audience.

Tackling climate change requires both systemic changes and individual lifestyle changes. Are those best placed to understand the risks and solutions to climate change acting on their knowledge? In a large-scale study of N = 9220 researchers across 115 countries, we found that climate researchers reported engaging in considerably more advocacy and activism on climate change and, to a lesser extent, high-impact lifestyle changes than non-climate researchers.

This paper is a call to action. By publishing concurrently across journals like an emergency bulletin, we are not merely making a plea for awareness about climate change. Instead, we are demanding immediate, tangible steps that harness the power of microbiology and the expertise of researchers and policymakers to safeguard the planet for future generations.

Climate action under the Paris Agreement (PA) requires a strategic approach that addresses the climate action needs of the participating countries. The most relevant documents for identifying such needs are the nationally determined contributions (NDCs) submitted by the parties to the PA. Academia has paid insufficient attention to this dataset and has attempted to clarify climate action pathways by utilizing various established theories from different fields. As a result, a strategic framework for global climate action is lacking. This article examines the NDCs of 19 lower-middle-income countries (LMICs) to consolidate their climate action needs into a cohesive framework. A grounded theory approach with process coding techniques is employed, and the data are analyzed through three coding cycles: initial process coding, focused process coding, and conceptual process coding. The results suggest a 4 A cyclic process: assess, arrange, access, and action, which forms an integrated global response to climate change.
巴黎协定》（PA）下的气候行动需要一种战略方法来解决参与国的气候行动需求。确定此类需求的最相关文件是《巴黎协定》缔约方提交的国家决定的贡献（NDCs）。学术界对这一数据集关注不够，并试图利用不同领域的各种既定理论来阐明气候行动路径。因此，全球气候行动缺乏战略框架。本文研究了 19 个中低收入国家（LMICs）的国家发展目标（NDCs），将这些国家的气候行动需求整合到一个具有凝聚力的框架中。文章采用了过程编码技术的基础理论方法，通过三个编码周期对数据进行分析：初始过程编码、重点过程编码和概念过程编码。结果表明了一个 4 A 循环过程：评估、安排、获取和行动，形成了一个综合的全球气候变化应对措施。

In recent years, new social movements advocating climate action have emerged, varying in demographics and tactics. A notable parent-led movement, driven by the moral imperative to care for future generations, offers a unique perspective on climate action. Despite its growing presence in local and regional debates, it remains under-explored. This Brief Communication highlights the movement’s potential to reshape climate action narratives and introduces an open-access database mapping its global reach, suggesting avenues for future research.

Science centers and museums are uniquely positioned to spark climate action. In this commentary, we describe opportunities to further increase the field’s impact through research on the psychological states that drive action and public engagement approaches for sparking those states. We also introduce Seeding Action, an initiative led by the Association of Science and Technology Centers to address the opportunities for cross-museum research and coordination.
