  Introduction:

  The proponents of “gains-from-trade hypothesis” contend that global trade improves resource allocation and leads to greater capacity for environmental management. The opponents argue that the competition mechanism of the international market pushes the production of resource intensive products into countries with lower cost of resource use, lower environmental standards and less efficient resource-use technologies. In this research, we address the above debate from a different angle: Whether observed changes in global trade patterns help or hinder the global efforts on climate change mitigation and environmental protection. We employ a global Multi-Regional Input–Output (MRIO) approach to quantify the impacts of changes in global trade patterns on carbon emissions, land use and water consumption between 2004 and 2011. The results show that if the trade patterns in 2004 had been remaining, the global CO2 emissions and water consumption in 2011 would be 669 million tons (2.7%) and 30 billion m3 (0.9%) lower, but the global land use would be 14 million hectares (0.2%) higher than the actual figures, meaning that trade patterns became less carbon and water efficient but more land efficient between 2004 and 2011.
