This volume illustrates the relationship between environmental factors and economic development of countries from various angles. Global warming has become a problem that threatens the whole world, especially in recent years. It is known that the main reason for this is carbon emissions. On the other hand, carbon emissions generally consist of fossil fuel-based energy consumption. This situation creates very serious environmental problems. Because of this problem, the concept of carbon zero has become very popular, especially in recent years. Many countries take some actions to minimize carbon emissions. Especially in the coming years, carbon emissions will become a competitive factor for countries and businesses. In this respect, countries with low carbon emissions will be preferred more in foreign trade. In addition, businesses that do not generate carbon emissions in the production process will also gain a significant competitive advantage in international trade. The contributions take a multidimensional outlook to energy investments and offer solutions for decision-making for energy projects in risky business ecosystems.
