Small and Medium Enterprises (SMEs) play a crucial role in the economies of many countries, particularly in emerging markets. They represent the bulk of businesses in these regions and are key to driving economic growth, creating jobs, and contributing to global economic advancement. Despite their significant impact, SMEs frequently face challenges related to financing. Previous research has investigated various factors influencing SME growth, with a focus primarily on traditional bank loans and equity financing. This focus often puts SMEs at a disadvantage compared to larger firms. However, green bond, a form of green financing, targets capital for sustainable projects which can be more favourable to SMEs in emerging economies. The researches that exist have focused more on the how small enterprise performance and sustainable innovation have been influenced by green bond especially in emerging economies. This is why this study’s aim is to assess the effect of green bond financing on SME growth in emerging economies. By utilizing panel data analysis, the study will examine data across multiple emerging countries over time, managing differences and capturing changes. The study is expected to show a positive correlation between green bond financing and SME growth, highlighting green bonds’ potential to drive sustainable development in emerging markets. The findings provide valuable insights for policymakers, financial institutions, and entrepreneurs, advocating for the adoption of green bonds as a viable financing option.
