Purpose: The urgency to control and reduce environmental disasters to the air and water as well as plastic pollution, acute deforestation, industrial waste, chemical spills, climate change and global warming calamity has triggered the universal Sustainable Development Goals (SDG) policy. Thus, diverting the attention of every level of human activity towards attaining a ‘sustainable’ environment. This universal war against such environmental disasters has developed a reason to incorporate SDG policy goals into the Competition Law and Policy (CLP) globally. This exploratory study aimed to determine the symbiosis between the competition law and United Nations (UN), SDG policy application under Competition Act 2010 for promoting and enhancing Green Marketing (GM) in Malaysia. 
 Methodology: The study examines viable options for competition regulators to address sustainability policy for green marketing (GM) benefits under the scope of CLP. The study applies qualitative analysis by way of comparative study to the European Union (EU) approach to determine GM marketing legitimacy for acclaiming SDG policy as a criterion within the exemption proviso in the Competition Act 2010, Malaysia.
 Findings: Competition Law can support GM sustainability initiatives to improve the environment since GM is not just about producing and marketing environmentally sustainable products but from a broader perspective contributes to innovation and consumer welfare. Hence, GM's social market and societal benefits towards sustainability objectives are arguably considered to outweigh its countervailing anticompetitive effects for sustainable exemption policy under the CLP. However, GM can only substantially contribute to addressing global warming and the environment under the SDG if applied legitimately. In addition, the GM must be also endorsed to incorporate broader environmental-related benefit policy within its competition law prohibition and exemption framework to resonate with the UN’s SDG.
 Implications/Originality/Value: The endorsement of GM sustainable benefits by way of exemption, exception or being pro-competitive allows a fair competitive advantage for GM industry growth. The research examines and proposes the exemption options for GM-related mergers, a collaboration by way of agreement and government exception policies under CA2010.
