A Narrative Review of Energy Label Towards Sustainability

Energy labels are crucial for promoting energy efficiency and sustainability in modern consumer markets. The labels provide transparent information about the energy efficiency of appliances, buildings, and vehicles, to name a few. Furthermore, they promote numerous benefits to the people and environment by reducing energy costs. Notably, the energy label emerged during the post-1970s oil crisis to address global energy insecurity and conservation measures. It now encompasses diverse products, standardises metrics, and facilitates consumer comparability in purchasing decisions. Despite their potential, a significant issue lies in the inconsistent global adoption and enforcement of energy labelling standards, which creates barriers to widespread consumer understanding and market impact. In addition, limited research addresses the long-term effectiveness of energy labels in driving actual consumer behaviour change. Thus, this study employs a narrative review methodology to explore the historical development, evolution, impacts, and challenges of energy labels as a catalyst for sustainability, focusing on their significance and limitations. The study reveals that implementing energy labels is a significant step towards promoting energy efficiency and sustainability, potentially reducing energy costs. However, challenges such as a lack of consumer awareness about the benefits of energy labels hinder their effective implementation. In summary, energy labels are crucial in promoting sustainable energy by empowering consumers, incentivising innovation, and promoting environmental stewardship. This includes reducing greenhouse gas emissions and promoting informed decisions for climate change mitigation, thereby contributing to a greener, more resilient planet.
