ABSTRACT Environmentally sound technologies or low-carbon technologies promote Sustainable Development. The environmentally sound technologies (ESTs) are concentrated in the hands of multinational corporations in developed countries. The paper presents the requirement for the equitable distribution of the ESTs. The paper describes the international legal framework governing the transfer of low-carbon technologies. International technology transfer takes place through trade and trade rules obviously expedite the transfer. In view of the requirement of ESTs worldwide, this paper examines the mechanisms of transfer, the factors that drive the transfer and the barriers that hamper the transfer. Deeply analysing such factors is required to formulate rules, regulations, and policies that enhance the transfers. This Article reviews the role of patents and trademarks in the transfer of ESTs. The paper also analyses the TRIPS provisions that drive the supply of ESTs. Further, this paper investigates trade-related measures for technological drive in the light of climate change and the legal backdrop
