At present, some of the most primary global concerns are climate change and environmental sustainability. It is obvious that the food system contributes significantly to climate change as well as there is further pressure on the food system to supply food for the global population, which is projected to reach 10 billion by 2100. According to strong evidence, human contributions to climate change are enormous and that Greenhouse Gas (GHG) emissions are the main drivers behind climate change. A major source of GHG emissions is our food system, which produces large amounts of waste and GHG emissions, especially from the production of livestock. The food system isn’t noted as sustainable because it relies on natural resources and is partly responsible for global pollution. Technological advances will act a key role in decreasing these negative results but consumers will also play a role with food choices having an impact on environmental decisions in this manner. The more concerns about health and environment of people the more taking care of consumption of organic food, environmentally conscious nutrition. This issue is represented by the term of Green Eating (GE). It is the concept of practicing more environmentally conscious eating behaviors and is currently defined as: eating locally grown foods, limited amounts of processed/fast foods, eating meatless meals at least one day per week, choosing organic foods as much as possible, and only taking what you plan on eating.  One of the most significant effects of GE is helping to reduce the GHG emissions from food production and other environmental impacts of food production.  Moreover, evidence supports the association between GE and improved dietary quality. This change caused by GE on a personal level can have great benefits to the environment. Researches show that altering one’s diet, including following a plant-based diet and limiting or excluding meat intake, can reduce a person’s diet-associated GHG emissions by up to 50%. Consequently, increasing GE behaviors could support a more sustainable food system, as well as promote healthier eating patterns.
