The trend in the flourishing e-commerce has also raised concerns about the impact that the industry poses in the environment, especially in terms of causing greenhouse gases. In this study, the synergy between consumer views on sustainability and institutional behaviours regarding the use of renewable energy and being sustainable as a decarbonisation tool is tested with reference to the Indian setting. The empirical evidence demonstrates that the impact of consumer perceptions on the readiness of consumers to incorporate sustainable practices is high, whereas the growth of the FMCG industry, and the implementation of renewable sources of energy are also instrumental in fuelling the carbon emission trends in India, and together, they also may indicate their potential to lower the level of emissions in the context of e-commerce, among other aspects. In turn, the current examination provides policymakers and market participants with an evidence-based scheme of developing low-carbon digital-commerce environments
