Innovation, particularly environmental innovation, is essential for long-term company success. This study presents a systematic review of the relationship between eco-innovation and sustainable performance, focusing on the influences of country of origin, industry type, and company size. A comprehensive selection process reduced an initial pool of studies to 55 relevant papers. Some studies examined the direct relationship between eco-innovation and overall sustainable performance, finding primarily significant and positive outcomes. Specific dimensions of eco-innovation, such as eco-product, eco-process, and eco-marketing innovations, positively impact various aspects of sustainable performance. However, some studies noted non-significant relationships, indicating that environmental innovation does not always affect environmental, financial, or social performance. Several studies also incorporated moderators and mediators to understand these relationships better. Most of the research was conducted within the manufacturing sector in developing countries and included companies ranging from micro-enterprises to large corporations. The findings suggest that eco-innovation enhances sustainable performance; however, the impact varies significantly depending on the context. Notably, there are substantial gaps in the literature concerning the service industry and the differential effects on small and medium-sized enterprises (SMEs) compared to larger firms. This indicates a need for future research to delve into eco-innovation within the service sector, the challenges SMEs face in adopting eco-innovations, and the contextual factors affecting the relationship between eco-innovation and sustainable performance. Moreover, the current body of research is skewed towards developing countries, suggesting an imbalance that future studies should address by including more data from developed nations. Such an approach would provide a more comprehensive global perspective on the relationship between eco-innovation and sustainable performance. While eco-innovation generally benefits sustainable performance, its varying impact across different industries, company sizes, and countries highlights the necessity for diversified research in this field.
