Links in the Chain: Global Carbon Emissions and Consumption Difficult to Attribute
(Science Daily) …A team led by Carnegie’s Steven Davis, and including Ken Caldeira, tracked and quantified this supply chain of global carbon dioxide emissions. …Traditionally, the carbon dioxide emitted by burning fossil fuels is attributed to the country where the fuels were burned. But until now, there has not yet been a full accounting of emissions taking into consideration the entire supply chain, from where fuels originate all the way to where products made using the fuels are ultimately consumed.
“Policies seeking to regulate emissions will affect not only the parties burning fuels but also those who extract fuels and consume products. No emissions exist in isolation, and everyone along the supply chain benefits from carbon-based fuels,” Davis said.
…Davis and Caldeira say that their results show that enacting carbon pricing mechanisms at the point of extraction could be efficient and avoid the relocation of industries that could result from regulation at the point of combustion. Manufacturing of goods may shift from one country to another, but fossil fuel resources are geographically fixed. READ MORE Access Study
