Fossil Fuel and Cement Emissions
Global fossil fuel and cement emissions: 9.7 ± 0.5 GtC in 2012, 58% over 1990 Projection for 2013 : 9.9 ± 0.5 GtC, 61% over 1990
With leap year adjustment: 2012 growth rate is 1.9% and 2013 is 2.4%
Source: Le Quéré et al 2013; CDIAC Data; Global Carbon Project 2013
Uncertainty is ±5% for one standard deviation (IPCC “likely” range)
Observed Emissions and Emissions Scenarios
Emissions are on track for 3.2–5.4ºC “likely” increase in temperature above pre-industrial Large and sustained mitigation is required to keep below 2ºC
Fossil fuel and cement emissions only Linear interpolation is used between individual data points

How to share the mitigation challenge?
Depending on perspective, the importance of individual countries changes

Top Fossil Fuel Emitters (Absolute)
Top five emitters in 2012 covered 63% of global emissions China (27%), United States (14%), EU28 (10%), India (6%), Russia (5%)
With leap year adjustment in 2012 growth rates are: China 5.6%, USA -4.0%, EU -1.6%, India 7.4%, Russia 4.8%. Source: CDIAC Data; Le Quéré et al 2013; Global Carbon Project 2013
Top Fossil Fuel Emitters (Per Capita)
Average per capita emissions in 2012 China is growing rapidly and the US is declining fast

Historical Cumulative Emissions by Country
Cumulative emissions from fossil-fuel and cement were distributed (1870–2012): USA (26%), EU28 (23%), China (11%), Russia (8%), and India (4%) covering 71% of the total share
Cumulative emissions (1990–2012) were distributed USA (20%), EU28 (15%), China (18%), Russia (6%), India (5%) Source: CDIAC Data; Le Quéré et al 2013; Global Carbon Project 2013

The mitigation challange
• “Common but differentiated” leads to fragmented policies
• Strong, weak, none • Global commons
• “Free rider” problems • Relevant in a global economy
• Carbon leakage • Competiveness concerns

Large share of consumer emissions are territorial
“Imported” emissions
miljøpartiet de grønne 14/06/2014
miljøpartiet de grønne 14/06/2014
Consumption-induced: The increase in net import into Annex B countries 1990-2008 was five times greater than the achieved emission reduction
miljøpartiet de grønne 14/06/2014
Policy-induced: Negligible effect 0.3% of territorial
Consumption-induced: The increase in net import into Annex B countries 1990-2008 was five times greater than the achieved emission reduction
miljøpartiet de grønne 14/06/2014
Carbon leakage
• Policy-induced carbon leakage • Caused by climate policy • Small at today’s carbon prices
• Consumption-induced carbon leakage
• Caused by a changing division of labour • Increased consumption, met by imports • Large, but not related to carbon prices
miljøpartiet de grønne 14/06/2014
Carbon footprints and scale
• Scale is important for footprints
• Big country, small share imported
• Small country, large share imported
• City, most imported
• Household, all imported

Consumption policies
• Country level consumption cap, border carbon adjustment
• Complex, equity issues • Financial transfers along trade flows
• Labelling • Generally ineffective
• Information (less meat, less flights, ...) • Not effective at the aggregate (nationally)
• Rebound effects

Trade and Carbon
Relevant in two ways
1. Trade in fossil fuels (physical) 2. Trade in goods and services (embodied)

EQUITY
miljøpartiet de grønne 14/06/2014
Consumption more just?
• “Emissions should be allocated to consumption because it is fairer”
• Consumption policies implicitly/explicitly put a price on imports
• Developing countries are worse off! • (they have to mitigate our consumption) • Offset this by financial transfers
miljøpartiet de grønne 14/06/2014
Extraction more just?
• “It is fairer to make fossil fuel exporters pay for the carbon they extract”
• Revenue • Could be used for financial transfers • Buy support for carbon price by letting
extractors keep the income
miljøpartiet de grønne 14/06/2014
POLICY IMPLICATIONS
miljøpartiet de grønne 14/06/2014
The policy problem
• Differential carbon pricing Countries unwilling to deepen and broaden climate policies unilaterally
• Two main issues • Competitiveness concerns (economic) • Carbon leakage (environmental)
• International trade is a key factor
miljøpartiet de grønne 14/06/2014
Extraction Extractors collect tax revenue
In principle easy
Production/Territorial Easy and status quo
Fragmentation, free riders, carbon leakage
Consumption Puts focus on key drivers Complex (and uncertain)
Alternate carbon policy
