The WTO's specific contributions to the SDGs also include: ensuring access to affordable medicines in developing countries (SDG 3.b): implementing the principle of special and differential treatment to help reduce inequalities (SDG 1Q.a): and ongoing discussions on eliminating subsidies that cause overfishing and overcapacity (in order to help achieve SDG 14.6). In addition, the WTO's work on the reduction of tariff and non-tariff barriers on environmental goods and services can facilitate the diffusion of green technologies and therefore directly contribute to environmental sustainability. In this way, the WTO can ensure that the multilateral trading system contributes to building a more favourable global environment for inclusive growth and development. Over the past twenty years, international trade has undergone major changes due to a variety of economic, political and technological factors. Undoubtedly, one main leading factor of change has been the unprecedented pace of technological innovation, which has transformed traditional ways of conducting trade. Advances in ICTs have led to reduced costs and increased speed and efficiency of economic transactions, with significant productivity gains for the global economy.
