Environmental policy plays a major role in integrating environmental protection goals into economic policy areas. Environmental deterioration will proceed rapidly until this intersection is successfully achieved. The paper uses European Green Deal as a reference for fostering sustainable development goals through competition laws. This paper discusses sustainability in the context of the competition laws of various jurisdictions such as the European Union (EU), the United States (US), the United Kingdom (UK), and India. While highlighting conflicts around the intersection of competition law and environmental policies, this paper also provides their solution for making competition law environment-friendly. It suggests implementing such laws to promote sustainability and progress toward climate neutrality.
