Measuring Carbon Dioxide Emissions Embodied in Consumption Paris, November 2010 Contact: firstname.lastname@example.org
Overview Policy drivers: –Production versus Consumption (Supplementary index). –Equity
Background – Where are we now? 40% increase in CO2 emissions between 1990 and 2007. ¼ from OECD economies, but over half from China alone; whose emissions trebled over the period – partly in response to domestic demand but also for OECD consumers. –Chinas share of US and Japanese imported goods up from 6.5 and 11% in 1995 to 15.5 and 21% in 2005. Much of this in products with high CO2 emissions. OECDs trade balance fallen from broad balance in 1995 to $1.1 trillion deficit in 2005.
Methodology Objective – to allocate emissions (embodied) to final domestic consumption. Starting point: 3 global IO tables for 1995, 2000 and 2005 for 47 countries. – 95% of global GDP and 85% of emissions. And CO 2 emissions by sector from the IEA
+32 OECD countries + 15 non-members (G20, BRIICS, ASEAN6,NAFTA, accession countries, other EU members) History 1995ed: 10 countries (1970-1990) 2002ed: 24 countries for mid90s 2006ed & current: mid90s-2005 Format Inter-industry transactions (48 sectors) ISIC 3 harmonized classification Import &domestic inputs are separated Database and sample indicators are available at OECD.Stat www.oecd.org/sti/inputoutput OECD Input-Output Database

Imported emissions embodied in final consumption-% of total consumption
CO 2 emissions from domestic consumption and production – Mt US per capita emissions from production 5 * Chinas in 2005 but 6 * higher with consumption
Trade balance in CO 2 emissions (domestic production minus domestic consumption) percentage of global emissions 1995 - 2005 Perspective: Higher than total emissions in Germany and growth in deficit between 1995 and 2005 equal to another UK
CO 2 emissions: tonnes per capita - domestic production and domestic consumption No change in per capita emissions in production between 2000 and 2005 but 2% increase in emissions embodied in consumption Difference in consumption and Production = 30% of per capita emissions in R.O.W
Not just a question of Trade surplus/deficits either: Trade in goods balances and CO 2 balances (2005)
China: Emissions from China embodied in imports: % of total consumption
Per capita Changes in Domestic Consumption of CO 2 emissions broken down by emission source between 1995 and 2005
Emissions embodied in HHFC: Mt per capita, 2005
CO 2 emissions in Households per unit of Household disposable constant 2000 PPPs, Mt CO2,
On-going work Emissions from unallocated autoproducers Emissions from the rest of the world Conceptual challenges relating to emissions embodied in investment and inventories. Focus on final consumption (households and government). Projection into recent years and back to 1990.
