Summary: Climate change and development are closely linked, requiring alignment between climate finance and development priorities. The study finds that climate-related official development assistance (ODA) contributes to multiple Sustainable Development Goals (SDGs). There is substantial alignment between donors and recipients in terms of SDG priorities, but this alignment has not improved in recent years. Climate finance is more allocated to mitigation than adaptation, but the difference has reduced.

Summary: Economic inequality and climate change are crucial issues, with the Global North and wealthier classes being the main drivers of global carbon emissions. Reducing income inequality can help reduce carbon footprint inequalities, but it may not significantly decrease total emissions. Recomposing consumption by reducing inequalities in household expenditure and reallocating the reductions to public services can lead to significant reductions in carbon footprint on both individual country and global levels.

Summary: This study examined NDCs from 185 countries and found that countries not mentioning health were mainly clustered in high-income countries, while greater health engagement was seen in low-income and middle-income countries. Factors such as low GDP per capita and being a small island developing state were associated with higher levels of health engagement. The focus on health in NDCs follows broader patterns of global inequalities.

Summary: Tracking progress towards the Paris Agreement climate goal requires understanding the emission levels implied by countries' NDCs. This study analyzes uncertainties and assumptions impacting emission projections. The findings suggest that uncertainties significantly affect global GHG emission projections, with historical emissions, socio-economic baseline, and policy uncertainty being important factors. This insight is important for decision makers and researchers as policy decisions can influence a larger share of the total uncertainty compared to previous analyses of NDC uncertainty.

Summary: With increasing urbanization, cities play a significant role in global greenhouse gas emissions. Therefore, it is important to develop tools to help local governments measure and monitor the consumption-based climate change footprint of cities. This study introduces a parsimonious screening tool that uses easily accessible city data and multiple regression models. The findings show that only a few cities are on track to achieve the necessary levels for greenhouse gas emissions by 2030, highlighting the need for major actions in cities worldwide to mitigate climate change.

Summary: While large companies have historically set greenhouse gas emissions targets, few have aligned these targets with global climate goals. The creation of the science based targets (SBTs) initiative in 2015 marked a shift towards this alignment, with over 500 companies now setting emission targets in line with the temperature goal of the Paris Agreement. However, various methods used to set these targets, and combinations of methods, often result in an imbalance between corporate targets and global allowable emissions.

Summary: The German Constitutional Court's climate verdict has significant implications for liberal constitutional law, including EU and international law. The ruling recognizes human rights as globally applicable and applies the precautionary principle to protect these rights. However, it fails to address important violations of human rights and overlooks the implications of the Paris Agreement's carbon budget limit. Moreover, it highlights the need for reform in the EU emissions trading system to achieve greater climate protection.

Summary: Research shows that achieving the goal of limiting global warming to 1.5 degrees Celsius requires the use of multiple mitigation measures, and a careful assessment of the feasibility and implementation plans for these measures. A subset of 1.5 degrees Celsius scenarios has emissions ranging from 15-22 Gt CO2 in 2030, and the range for reaching net zero emissions is 2039-2061.

Summary: The circular economy has potential synergies with climate change mitigation, but quantitative evidence for these synergies in the consumer product sector has not yet been systematically evaluated. This study conducted a systematic review of existing studies on the lifecycle impacts of consumer-oriented product-service systems (PSS) and found that adopting circular economy strategies can reduce greenhouse gas emissions, but comes with risks. Certain strategies such as upgrading, repair, refurbishing, and pooling have moderate to high improvement potentials with lower risks of backfiring, while strategies like servitisation, sharing, and reuse have higher backfire risks, but also high improvement potentials. The risk of backfiring is influenced by factors such as transport, number of uses, product substitution and lifetime, maintenance, energy source, and energy efficiency.

Summary: Understanding the greenhouse gas emissions associated with household food consumption is crucial for reducing overall emissions. In Brasilia, meat consumption is the largest contributor to emissions, followed by beverages and cereals. Sociodemographic factors and dietary patterns also play a role in individuals' carbon footprints, with men, individuals living in houses, and those between 45 and 54 years old having higher emissions. Vegan and other plant-based diets result in significantly lower emissions compared to omnivorous diets.

Summary: Product service systems (PSS) are gaining attention for their potential in achieving a circular economy, yet there is a lack of effective evaluation methods. This study combines life cycle assessment (LCA) and a consumer survey to quantify the environmental consequences of PSS, using the example of digital camera rental services in Japan. Results showed that the rental scenario increased greenhouse gas emissions but also reduced abiotic depletion potential compared to conventional purchase. The study highlights the importance of carefully designing PSS to mitigate unintended consequences.

Summary: This study analyzes the changes in the relationship between donor characteristics and mitigation Official Development Assistance (ODA) before and after the 2009 Copenhagen Accord. Using panel data from 23 countries over 15 years, multiple regression analysis was conducted. The findings show that donor countries with a stronger commitment to climate change provided a smaller share of mitigation ODA before 2009, but this reversed after the accord. Moreover, donor countries with higher GDP per capita and lower CO2 emissions per capita contributed a larger share of mitigation ODA after 2010 compared to before.
