The study investigates the cost of nutritionally adequate and low-GHGE diets in Finland, using optimization models. Minimum cost diets significantly reduce carbon footprints and expenses but lack diversity and cultural acceptability. The culturally acceptable diets, while slightly cheaper and with lower climate impact than current diets, highlight that affordability isn't the main barrier; cultural acceptability is. Reducing GHGE further decreases diet costs. The study concludes that sustainable dietary changes should focus on taste, convenience, and social norms alongside nutrition and affordability.
This study supports SDG 3 and 13 by showing that human activities will amplify future heat-related cardiovascular mortality burden, highlighting the significance of limiting greenhouse gas emissions and further warming of the planet.
The paper explores maritime environmental regulations, analyzing industry perspectives and their operational execution.
This One Earth Research Article documents how (mostly) European cities are planning to adapt to increasing heat risk due to climate change (SDG 13 & 11).
This One Earth Commentary discusses how policy makers could accelerate social change towards climate action (SDG 13) in their cities and communities (SDG 11) by reducing early inertia.

This research has uncovered the conflicts between solar-energy development and the conservation of threatened bird species. A comprehensive analysis has revealed that a staggering 97.4% of regions with significant solar-energy potential overlap with the ranges of multiple endangered bird species. Even more alarming is the fact that over 17.0% of these areas are home to at least 10 threatened bird species. These findings highlight the urgent need to address the potential negative impacts of solar-energy projects on avian biodiversity.

In the pursuit of improving engine performance and mitigating emissions, researchers have explored the intriguing domain of fuel blends incorporating butanol and gasoline. This innovative study aims to unravel the intricate dynamics between butanol and gasoline when utilized as a blended fuel in internal combustion engines. The current study integrates cutting-edge techniques such as Artificial Neural Networks (ANN) and Response Surface Methodology (RSM) for the optimization of engine performance.
In this current study, six metropolitan areas were selected to differentiate the built-up landscapes by utilizing the concept of local climate zones. Results revealed a 30.67% higher heat health risk in compact built-up landscapes than in the open built-up type, with urban green spaces playing an effective but differentiated role in mitigating risk.

Transportation electrification is a critical step toward energy transition and a low-carbon society, with wide-ranging social and economic impacts. This study examines the significant role of the 2023 United Auto Workers strike in the context of transportation electrification, with a focus on its implications for the automotive industry and labor market dynamics.
