Climate change resulting from a rapid increase in greenhouse gas (GHG) emissions is adversely affecting humanity. If the GHG emission continues to rise at the current pace, humanity will face severe consequences and reverse all the progress made. This paper, therefore, uses relevant data from 14 developing countries in Asia from 1990 to 2018 to examine the potential impact of environmental innovation on CO emissions by controlling globalization, urbanization, and economic growth. The number of environmental-related technology patents is used as a measure of environmental innovation. We employed a panel long-run regression model - FMOLS, PCSE, and FGLS to estimate the elasticity of CO emissions. For causal association among variables, we used Dumitrescu-Hurlin Granger causality tests. Our results show that renewable energy consumption and globalization have a significant impact in reducing CO emissions, while environmental technology innovations play a meager role in reducing emissions and only when economic growth support those type of investment. Furthermore, we found urbanization, oil consumption, and economic growth is detrimental to the environment, which is also evident in past studies. Therefore, countries should invest in renewable energy and environmental innovation aligned with the growth to reduce GHG emissions.
气候变化是由于温室气体（GHG）排放的迅速增加而产生的，正在对人类造成负面影响。如果温室气体排放继续按照目前的速度增长，人类将面临严重后果，并使所有取得的进展都化为泡影。因此，本文利用 1990 年至 2018 年亚洲 14 个发展中国家的相关数据，通过控制全球化、城市化和经济增长，检验环境创新对 CO 排放的潜在影响。环境相关技术专利数量被用作环境创新的衡量标准。我们采用面板长期回归模型——FMOLS、PCSE 和 FGLS 来估计 CO 排放的弹性。为了检验变量之间的因果关系，我们使用了 Dumitrescu-Hurlin 格兰杰因果检验。结果表明，可再生能源消费和全球化对减少 CO 排放有显著影响，而环境技术创新在减少排放方面作用有限，只有在经济增长支持这类投资的情况下才会发挥作用。此外，我们发现城市化、石油消费和经济增长对环境有害，这在过去的研究中也得到了证实。因此，各国应投资于可再生能源和与增长相匹配的环境创新，以减少温室气体排放。
