Fragmentation Across Scales, Geography, and Climate Challenges in European Urban Climate Change Adaptation and Mitigation Research: A Bibliometric and Systematic Review

Sustainable Development, EarlyView.
ABSTRACT European urban climate change research lacks integration across scales, geography, and climate challenges, despite Europe's coordinated policy frameworks. Through a hybrid bibliometric and systematic review of 1528 studies (2010–2025) using Cortext Manager and PRISMA 2020 guidelines, this study maps the conceptual patterns, knowledge gaps, and

Sustainable Consumption and the “Last‐Mile” Problem: Cultural and Neural Mechanisms of Near‐Expiration Date Bias in Meat Purchases

Sustainable Development, EarlyView.
ABSTRACT Food waste poses escalating environmental costs and economic losses, with near‐expiration‐date bias limiting the effectiveness of discount‐based waste‐reduction initiatives. This study examines how expiration‐date cues, interacting with consumer identity, shape responses to discounted meat products through emotional and neural mechanisms in ...
