3 Introduction (1/3) CO2 Emissions in 2010 (Million tons) (2): 43% (5): 58% (20): 81% (30): 88% (10): 68%

4 Introduction (2/3) Countries in terms of absolute emissions and per Capita emissions in 2010 Vertical Axis – Per capita emissions (ton per capita) Horizontal axis – CO2 emissions (Million Tons)

5 Introduction (3/3) Per capita CO2 emissions (tons) 14% lower from 1990 level 72% higher from 1990 level Intensity gap (7.4) (11.8 tons) (10.2 tons) (1.6 tons) (2.7 tons) (-20%) Intensity gap (10.3) Although, emission intensity gap is decreasing, industrialized countries, on average, still release 3.7 times as high as CO 2 emissions per capita than developing countries

6 The Question  Is stabilization of GHG concentrations to avoid climate change possible while converging the emission intensities between industrialized and developing countries? Provided that:  To avoid climate change (or avoiding dangerous consequences in the earth’s atmosphere), the earth mean average surface temperature should not be higher than 2 degree Celsius from the pre-industrialization level  Concentrations of CO 2 emissions should be stabilized below 450 PPM  Global emissions to peak before 2020, followed by substantial overall reductions of around 60% below the 2000 level by 2050

7 Our Approach  We introduced various levels of carbon tax (US$10 to 250 per ton of CO2) to Annex I countries to reduce their fuel consumption and thereby CO2 emissions and emission intensities.  Non-Annex I countries are exempted from carbon taxation, however they are impacted from Annex I countries carbon tax through international trade.  Since the emission intensities of Annex I countries would decrease in response to the carbon tax while Non-Annex I countries emission intensities would continuously increase, the intensity gap between these two groups of countries drops (i.e., we will be moving towards global convergence of emission intensities).  We used a global CGE model to simulate the effects moving towards global convergence of emission intensities.

8 Model & Data  Multi-sector, multi-region, global recursive dynamic CGE model  The model is flexible enough to accommodate new regions/countries or sectors and is calibrated with GTAP database  Nested CES and CET functional forms to represent production behavior and land supply, respectively  Representation of bilateral and international trade  Data are coming from the GTAP (Version 7.1)

9 Per Capita CO 2 Emission (tons) under Different Carbon Tax Rates 6.8 tons US$10/tCO 2 7.5 tons (- 9.4%) (- 36.5%) US$50/tCO 2 4.8 tons (- 71.6%) US$250/tCO 2 2.1 tons (- 51.6%) US$100/tCO 2 3.6 tons

10 Impacts on CO 2 Emissions Annex I Non-Annex I Global

11 Impacts on CO 2 Emissions in 2030 Limiting temperature rise below 2°C, CO2 concentrations must be below 450ppm Global CO2 emissions should be reduced 60% below 2000 level by 2050 Even at the very high carbon tax rate of $250/tCO2, we find that global CO 2 emissions in 2030 would be only 18% below from that in the baseline

12 CO 2 Emissions with $250 Carbon Tax Case Compared to 2000 Emission Level Compared to 2000 emissions level, the emission convergence scenario (72% reduction of intensity gap through $250 carbon tax) would, in 2030, - decrease Annex I emissions by 52%, but - increase Non-Annex I emissions by 3 folds, thereby - increase global emissions by 28% Annex I 2000 Global 2000 Non-Annex I countries emissions would exceed global 2000 level by 2030 if there emissions are not limited Even if developed countries CO2 emissions are completely wiped out, meeting 2 degree target would be far out of reach unless Non-Annex I countries emissions are limited

13 Impacts on GDP in 2030 The relationship between the carbon tax level and corresponding GDP loss is exponential There would be a carbon leakage effect (carbon intensive industries would move to Non-Annex I countries from Annex I countries). Despite the strong international trade linkage between Non-Annex I countries and Annex I countries, the former are not found to be negatively affected by the carbon tax in Annex I countries.

14 Combining Effects on GDP and CO 2 Emissions (2030) Non-Annex I countries are also expected to reduce their GHG emissions, in that case, emission intensity will diverge instead of converge

15 Impacts on International Trade in 2030  The carbon tax introduced in Annex I countries would cause international trade to shrink (up to 2% in the case of $250/tCO 2 carbon tax)  Since domestic production would be more expensive in Annex I countries due to carbon tax exports would get impacted the most  Non-Annex I countries would benefit as their exports increase and imports drop

20 Conclusions  Developing countries’ argument to converge global CO2 emission intensity could be reasonable from the equity perspective  However, their demand could not be realized in practice if global CO2 emissions are to be reduced to stabilize CO2 concentration to meet the ultimate objective of the UNFCCC  Limitations of GHG emissions is necessary in developing countries to avoid climate change; the 2 degree target can not be realized even if developed countries CO2 emissions are completely wiped out as long as developing countries’ CO2 emissions increase at the current trend
