The article examines how international trade affects greenhouse gas emissions. Researchers analyzed data from 40 countries over 1995-2009 to see emissions related to trade. They focused on CO2 emissions from production and consumption patterns. By using input-output analysis, they studied emissions in exports and imports to understand how countries deal with emissions. The study aimed to measure and compare countries' carbon footprints based on their trade activities. Key findings include identifying sectors and regions with high emission concentrations and tracking how countries use trade to manage emissions. The research provides insights into the carbon balance of different countries and the impact of global trade on environmental responsibilities.
