Abstract

Green hydrogen technology is crucial in reducing carbon emissions and advancing Sustainable Development Goals. This study explores the impact of green hydrogen technology budgets on carbon emissions in the top 10 countries with the highest R&D investment in green hydrogen technology (Japan, Germany, USA, China, France, South Korea, UK, Netherlands, Australia, and Canada) by using data from 2012 to 2023. Unlike previous studies, which depended on panel data techniques and often overlooked the specific economic landscapes of individual countries, this research employs the sophisticated Quantile-on-Quantile method to assess each country's unique patterns and behaviors. Findings reveal a strong negative relationship between green hydrogen budgets and carbon emissions in most selected economies. However, Canada and Australia show a mixed pattern. The findings highlight the need for policymakers to develop tailored strategies that leverage green hydrogen technology to reduce emissions and support sustainable development effectively.
