Sustainable development has become an increasingly important issue in international trade policy. Free trade agreements (FTAs) have reflected this evolution over time by covering a broader scope of sustainability measures and integrating specific languages. Initially, only a handful of countries incorporated sustainability provisions into their agreements; They are now a basic feature in most free trade agreements. The North American Free Trade Agreement (NAFTA) was the first U.S. agreement that linked trade and sustainable development. The EU has been another pioneer in this area and sustainable development has become one of the European Commission`s guiding principles on trade policy. Indeed, since the adoption of the FREE Trade Agreement BETWEEN the EU and South Korea in 2011, specific chapters on trade and sustainable development have been incorporated into all their free trade agreements. Both the EU-Japan and the EU-Mexico contain specific references to climate change. In CETA, there is no specific section, nor is there any mention of climate change, the UNFCCC or the Paris Agreement, nor any mention of trade and the transition to low GHG energy. However, the joint interpretive declaration issued on 14 January 2017 confirms that the parties are committed to cooperating on trade-related environmental issues, such as climate change and the implementation of the Paris Agreement.  Free trade agreements also deal with the content of the MEA. There are about 20 MEAs that contain trade-related provisions.
Such specific trade obligations may prohibit or restrict trade in certain products. However, the rules of application in these MEA are often weak, for example. B they apply only to the monitoring and reporting of offences committed by private agents such as NGOs. KSL is synonymous with quality system in agriculture. It ensures the quality and safety of farmers, industry and consumers. The KSL standard consists of checklists and controllers used when self-auditing the farm. It is based on laws and regulations and is a useful tool for farms.  The standard is divided into 12 separate checklists: two checklists with general requirements for exploitation, including detox and workplace safety and pollution control requirements on farms, as well as separate checklists for different types of production. Each facility uses checklists that are relevant to the farm`s production. Therefore, the farmer refers to only one system, regardless of his production.  The EU has some of the highest animal welfare standards in the world, which have been in place for decades, and animal welfare targets are anchored in the Common Agricultural Policy (CAP). The Commission`s recent animal welfare strategy aimed to address compliance issues and improve synergies with the CAP.
 With regard to animal welfare labelling in the EU, there are voluntary animal welfare labelling systems, but there is no harmonised system of animal welfare standards for labelling purposes. Very few products inform consumers about animal welfare standards and there is very little incentive for more producers to improve animal welfare and market their products accordingly. Currently, there is only one mandatory EU-wide animal welfare labelling system for table animals. The egg system is based on EU legislation on laying hens, which defines different production methods (cages, outdoor farming, stables, etc.). Such a classification of production methods does not exist for other types of animal production in the EU. The animal welfare strategy does not plan to go beyond mandatory labelling of animal welfare beyond eggs. Instead, the strategy aims to consider the development of an instrument to improve consumer information
