  1. A least-cost approach to reduce CO2-emissions in passenger car transport: This time economics will kill the electric car Amela Ajanovic Energy Economics Group Vienna University of Technology 30th USAEE/IAEE North American Conference Washington, 2011

  2. Introduction Method of approach Results - Which measures contribute to CO2 reduction and to which costs? Conclusions Content

  3. 1. Introduction

  4. 2. Methods Impact factors on CO2 emissions in the car passenger transport sector

  5. 2. Methods • So we can reduce CO2 emissions by influencing : • vkm (by increasing the price by taxes) or • FI (by introducing various measures for technical efficiency improvement) or • fCO2 (by using fuels with less carbon, e.g. biofuels or electricity).

  6. 2. Methods • The method of approach is finally based on calculation of total costs for society and resulting CO2 reductions: • For taxes these costs are the welfare losses for society; • For the technologies we consider the additional investment costs of the technology and the energy cost reduction respectively the increased producer surplus if the technology is produced in the region; • For alternative fuels we have to consider the additional production costs minus the increased producer surplus if the fuel is produced in the region.

  7. 3. Results • Policy measures implemented in transport sector could be put in three main categories: • Switch from fossil fuels to alternative fuels, in the first line to biofuels; • Improve efficiency of cars including switch to alternative and more efficient powertrains; • Reduce energy consumption with taxes and standards.

  8. 3. Results Switch Fossil fuels vs. biofuels production costs (exclusive taxes) and WTW CO2 emissions, 2010 and 2020

  9. 3. Results Improve Comparison of specific CO2 emissions and driving costs of conventional and hybrid gasoline and diesel vehicles with pure BEV and FCV

  10. 3. Results Reduce Evolution of CO2 emissions from new passenger cars by manufacturer associations (EC, 2010) Price structure of gasoline in EU-27 (data source: EEP, 2011 - effective March 2, 2011)

  11. 3. Results Which measures contribute to CO2 reduction and to which costs? Least-cost curve for CO2 reduction in passenger car transport in the EU-15 in 2010

  12. The major conclusion of this analysis is that technological solutions alone are a very expensive strategy for reducing CO2 emissions. Regarding BEV and fuel cell cars up to 2020 no CO2 savings at reasonable costs for society will be achieved. 4. Conclusions

  13. In the long-term only a very broad portfolio of policy instruments (taxes, standards, quotas, emissions free-zones…) and new technologies (BEV, FCV …) can reduce energy consumption and straightforward CO2 emissions significantly. It is currently of urgent importance that there is a clear focus on implementing the two instruments with highest short-term effects: standards and taxes. 4. Conclusions
