Deforestation emissions should be shared between producer and consumer, argues study

Under the Kyoto Protocol the nation that produces carbon emission takes responsibility for them, but what about when the country is producing carbon-intensive goods for consumer demand beyond its borders? For example while China is now the world's highest carbon emitter, 50 percent of its growth over the last year was due to producing goods for wealthy countries like the EU and the United States which have, in a sense, outsourced their manufacturing emissions to China. A new study in Environmental Research Letters presents a possible model for making certain that both producer and consumer share responsibility for emissions in an area so far neglected by studies of this kind: deforestation and land-use change.

It's not just China that is seeing emissions rise due to demand from other nations: deforestation of the Amazon in Brazil accounts for 75 percent of that nation's emissions, but most of the products produced on deforested land, such as soy and beef, are exported to other countries in Europe, Asia, and Africa.

"Brazil has some of the highest emissions from deforestation in the world and its exports of both soybeans and beef have grown dramatically in the last two decades," David Zaks, lead author and graduate student at the Center for Sustainability and Global Environment (SAGE) at the University of Wisconsin, Madison told Mongabay.com.

Brazil's high annual deforestation rates are currently supporting a massive agricultural industry that exports most of its product abroad: Brazil is the world's largest exporter of both beef and soybeans. Between 1990 and 2006, exports of beef increased by 500 percent. The soy boom, which began in the 1990s, did not cause as much direct deforestation, but pushed cattle farmers and small-land holders deeper into the forest.

From 1990-2006, EU countries and Asian countries were the primary importers of Brazil's soy, while importers of Brazil's beef came from around the world, including Eastern Europe, the EU, the Middle East, Asia, Africa, and other South American nations. Yet so far none of these nations have had to pay a cent for the environmental damage, including high carbon emissions, caused by the deforestation of the Amazon.

Zaks and his team have proposed a model to change this. According to their study when a product is exported half of the emissions should be the responsibility of the producing country and half of the importing country and its consumers.

"There is no 'right way' to proportion emissions between consumer and producer, but we did not think that assigning the burden of emissions to either Brazil OR the importing country would be logical," explains Zaks. "If emissions are assigned only to the importing country, there is a reduced incentive to decrease deforestation in the exporting country."
