Highlights

In response to the growing urgency of environmental challenges such as climate change, biodiversity loss, and resource scarcity, governments worldwide are intensifying efforts to regulate and standardize products to mitigate environmental impact. Among the promising avenues within clean energy, solar heating, and cooling systems stand out for their potential to contribute significantly to sustainable energy solutions. However, as advancements are made to increase their efficiency and affordability, it is necessary to ensure that these developments do not inadvertently introduce new environmental burdens. The heating and cooling sector, particularly air-conditioning, is witnessing rapid expansion propelled by technological innovations and increased efficiency. With this expansion comes an increased emphasis on environmental labeling tools, both compulsory and voluntary, aimed at ensuring product quality while supporting business opportunities for producers. Central to this effort is the need for standardized and reliable certification, which is essential for ensuring consumer trust.
