Chaopeng Hong et al. ,Land-use emissions embodied in international trade.Science376,597-603(2022)

Objective:

• No comprehensive global analysis of emissions from both agriculture and land-use change

Case:

• 141 countries

Methodology:

• MRIO

Data Source

• Input-output: GTAP

Findings:

• ~22% of agricultural land were used for traded agricultural products
• A ~27% land-use emissions are embodied in international trade

• The dominant global feature of embodied land-use emissions are large exports of emissiosn from countries such as Brazil, Indonesia, Argentina, Austrilia and Canada to consumers in developed regions such as the US, Europe and Japan

• Of the total global embodied land-use emissiosn, 75 to 81% are related to land-use change

• Brazil was the largest net exporter of land-use emissions in 2017, followed by Argentina, Indonesia, Thailand, Russia and Austrilia.
• The largest net importer of land-use emissions in 2017 was China, followed by the US, Japan, Germany, the UK, Italy, South Korea and Saudi Arabia
• Exports from Brazil, Indonesia, Argentina, Australia, Thailand and Tanzania are particularly emission-intensive

• The emissions intensity of exports from China, the US, Europe and Japan is much lower
• The exported land-use emissions from major exporters are usually dominated by a small subset of exported products
• Land use emissions embodied in global trade increased by 14% between 2014 and 2017; while the land area decreased by 5%
