2 Outline of presentation What is sustainable levels of GHG? Is technical measures sufficient? Urban planning and modal shift Energy efficiency Renewable energy Biogas 2

3 To avoid the most severe consequences, the increase in global mean temperature should be limited to 2 C relative pre-industrial time Picture from IPCC 4AR WG II 3

4 Why reduce climate change to maximum 2 C? Stabilise Arctic ice to avoid accelerating climate change and to minimise loss of Greenland ice Stabilise mountain glaciers to prevent loss of fresh water for billions of people Stabilise Antarctic and Greenland ice-shelves to prevent large increase in sea level Minimise expansion of deserts in subtropical areas Minimise acidification of sea (through dissolved CO 2 ) which make it impossible for corals and animals with shell to survive 4

5 What are the consequences of a 2 degree target? Globaly, CO 2 eq-emissions all sectors - 30% to 2030 (-20% relative to 1990) - 65% till 2050 (-60% relative to 1990) Vi måste agera nu! -30% - Industrialised countries CO 2 eqemissions all sectors - 40 percent to percent to percent to 2050 All (large) sectors have to contribute Note that this is in line with 350 ppm CO 2 since we also include other antropogene greenhouse gases.

8 All measures needed It is not sufficient with more energy-efficient vehicles partly run on electricity and an increased share of renewable energies in order to achieve the emissions targets that have been established both nationally and internationally..

11 INFLUENCE TRANSPORT NEEDS Energy efficiency Renewable energy Urban planning and modal shift 11

12 Influence of traffic growth Million tonnes per year % -14% Motorcycle and moped Heavy goods vehicle Bus Light goods vehicle Passenger car with constant traffic 12

13 The road towards a less car dependent society? Potential to 2030 Urban planning for less car dependence -10% Improved public transport -5% Increased focus on cycling and walking -5% Car sharing -5% Teleworking and internet-shopping -3% Congestion charge, parking policy and fee -5% Lower speed limits -3% Fuel/CO 2 - tax -13% Total -40% 13

14 Factors in urban planning that affect car use (Five Ds) Density Incresed density Diversity Mixed landuse Design Street network, possiblities to walk and cycle Destination accessibility Nearness to work and service Distance to transit Short distance to good public transport Parkingpolicy and costs 14 Growing cooler The evidence on urban development and climate change

23 Fossil energy sources (crude oil, coal, natural gas etc.) Biomass Hydro, wind, solar Nuclear Fossil fuels (petrol, diesel, CNG, LPG) Biofuels (Alcohols, Biodiesel, DME, Biogas) Electricity Hydrogen ICV (incl. HEV) PHEV EV FCV 23

25 Electric power is at the moment the only known technical system that is compatible with long term climate targets 25

26 Possibility for a shift in technology Lower battery cost Improved electric engine technology Radical new concepts made for electric power Thoroughly planned introduction strategy New business concepts New preferences for buyers 26

27 Substitute for fossil diesel critical! Demand on increased energy efficiency on LDV leads to increased share of diesel relative petrol HDV do not have same possibilities to increase energy efficiency and reduce traffic volumes as LDV Imbalance existing today between petrol and diesel in refinery will increase Aviation needs same components 27

28 Possible substitutes for diesel Biodiesel, in existing diesel engines FTD Fisher-Tropsch-Diesel HVO-Biocrude FAME/RME (only low blending) DME, in dedicated diesel engines Biogas, in dedicated diesel or spark ignition engines Electricity Battery in LDV Trolley bus Hydrogen Long term 28

29 Digestion Municipal waste/ manure Gasification Biomass Biogas Long haulage CI dual fuel, LBG Urban bus SI Distribution truck SI or CI dual fuel LDV SI 29

30 Dual fuel technical benefits and challenges Benefits Low CO 2 emissions especially for biogas High energy efficiency Possibility to use in long haulage Challenges Development of test procedures and legal requirements for dual fuel Engine and aftertreament that fulfils this throughout the useful life Liquid gas (needed for long haulage) Biogas production 30

31 Conclusions Very large reductions of greenhouse gas emissions are needed to stabilise the climate to less than 2 degree temperature increase. For road transport energy efficient vehicles and system, renewable energy and reduction in passenger car traffic are needed. Substitutes for diesel is critical. Biogas will play one part in this. 31
