The consumption and production of goods have a much wider impact than simply on the country or region where they are used or made. For example, the carbon footprint of global supply chains varies within and between countries, mostly according to economics and trade. Using spatial modeling, Kanemoto et al.linked carbon emissions maps to industrial activity across 187 countries from 1970 to 2008. The carbon footprints of developed countries such as the United States have become more globally diffuse over that time span, whereas hotspots of carbon footprints in rapidly developing economies such as India and China are located in their expanding urban areas.
