A study by scientists at the Carnegie Institution finds that over a third of carbon dioxide emissions associated with consumption of goods and services in many developed countries are actually emitted outside their borders. Some countries, such as Switzerland, "outsource" over half of their carbon dioxide emissions, primarily to developing countries. The study finds that, per person, about 2.5 tons of carbon dioxide are consumed in the U.S. but produced somewhere else. For Europeans, the figure can exceed four tons per person.

CIRAD and INRA have published the report of their Foresight exercise into possible farming and food systems worldwide in 2035. CIRA and INRA were commissioned to "produce scenarios of global and regional evolution in agricultural production, consumption and trade, as well as in scientific and technical knowledge on agriculture, with a view to drawing conclusions on the possible roles for research, public policies and international regulations." There were three phases of work:

The Welsh Assembly Government has published a report setting out how the agriculture and rural land use sectors in Wales can play play their part in reducing greenhouse gas emissions while maintaining food production. The report was commissioned by the Welsh Assembly and undertaken by the Land Use Climate Change Group, chaired by Professor Gareth Wyn Jones, with representatives from farming, forestry, research and environmental sectors. It is entitled Land Use Climate Change Report To Welsh Assembly Government, March 2010.
