4. 4 INSTITUTIONAL ARRANGEMENT (2) The scenario holds input from several national institutes, among others: CPB : economic related models ECN : energy related models RIVM: environmental related models

5. 5 Projections over the years 2. National communication –National environmental outlook 3 –Separate projection for CO2 related to energy use 2. National communication, update –National environmental outlook 4 3. National communication –National environmental outlook 5

6. 6 Problems in National communications 1 and 2, related to projections The use of long term scenarios for 5 year periods The requested and the needed detailed information Reference scenarios

7. 7 Long term scenarios Long time period : 2020 and 2030 Interpolation of 2010 situation and other 5 year periods Short time scenarios (4 year period) available but not the same assumptions as LT scenarios Conclusion we will keep only LT scenario

12. 12 Long Term scenario

13. 13 LT Scenario and 5 years period LT scenario 2030 or 2020 2010 already interpolation 5 years value again interpolation Almost all assumptions over whole period the same (see table 5.1) ST scenarios (4 year) do not fit with LT Usefulness of 5 years value ?

14. 14 Use and explanation of models New guidelines improve the understanding of scenarios Most Dutch models developed for other projections and (re)used for climate change scenario In 3. Communication more elements to explain models will be included

15. 15 Brief explanations and national documentation Brief explanation: scenarios are important, but should be seen as background information Guidelines improve transparency of scenarios and policy impacts Most references will be in Dutch

16. 16 Summary More transparency as more information will be presented Guidelines still hold a lot of interpretation options by countries 5 year data only illustrative In 3. Communication additional information to improve transparency
