In an effort to provide convenience, the paper discusses that there have arisen major environmental issues with the emergence of e-commerce, unrelated to the convenience, such as carbon emission, packaging, and logistics and data centre energy requirements. It thoroughly analyses these concerns, as well as determining the adverse effects (such as higher wastes and electric consumption) and the beneficial ones (such as a decrease in retailing area and effective control of stock). Besides, the study suggests remedies towards more sustainable e-commerce activities, such as sustainable packaging, green logistics, renewable energy, and measures to reduce the rate of returns. The paper wraps up by stating that collaborative efforts between companies, governments and consumers have to be made in order to ensure sustainable future of e-commerce.
