  1. CO2 Tool Workshop Sudhir Gota & Alvin Mejia Clean Air Initiative for Asian Cities Center ITDP's Annual Staff Meeting and ClimateWorks' Transport Systems Sector Meeting September 28 - October 2, 2010 Guangzhou

  2. How to Quantify CO2 emissions? Depends on many factors! • Scale of analysis – project, zonal, organizational, city , regional or national • Accuracy –sketch vs detailed • Project Duration? • Top down or Bottom Up? • When do want to apply this – ex-ante or ex-post? • Data availability ? • To what level of analysis or boundary – “hidden” ? “induced” ? “impact on landuse”? • Resources available? • Baseline – static or dynamic? • What do you want to do with results? • Cobenefits?

  13. Bikeways

  14. TEEMP Models – Bikeways

  15. TEEMP Models – Bikeways • Allows Sketch Analysis and Detailed Analysis • Sketch Analysis – In case the user does not have any data on expected mode share, shift, trip lengths etc. and still needs to assess the likely impact of bikelanes, experience gained from Latin America case studies of Rio de Janeiro and Bogota are useful. It’s assumed that roughly, 1 km of 2m wide bikeways would attract 2000 trips. These trips are then factored based on design and site considerations as shown in the sketch analysis • Detailed Analysis – • Uses before and after trip mode shares. • Includes construction materials – cement, bitumen and steel • Includes speed impact on emissions (based on COPERT and other models) • Allows quantification of PM and NOx emissions

  24. TEEMP Models – Walkability Improvement Projects • The savings are calculated in two stages • the no improvement scenario wherein the ‘walking trips’ % trip share in the total trips is assumed to go down through time due to deteriorating facilities coupled with raising motorization . • the improvement scenario i.e. after the project i.e. walking trips % share in the total trips will rise through time. • Input Parameters • Project Lifetime (Number of Years) • Starting Year Total Number of Trips/Day • Annual % Increase in Total Trips/day • Mode Share • Average Trip length • Emission Factor • Mode share deterioration due to no improvement/ annual decrease in walk trip share • Increase in walking trips due to improvement/ before and after walkability ratings/ annual increase in walk trip share

  25. TEEMP Models – Walkability Improvement Projects • Scorecard for assessing Walkability • Streets with protected walkway with width adequate to accomodate pedestrian volume and are kept barrier free (including parked cars & hawkers) with non obstructing furniture (40) • Adequately safe crossing facilities (crossing lights, crosswalk striping, raised crossings, or accessible grade seperated as needed depending on traffic volume) with active traffic calming (35) • Blocks/streets with shade/trees (15) • Block Size (scaling factor) • if the area in which the walkability improvements are being made is dominated by small block sizes (average block face of 200 meters or less) • if the area in which the walkability improvements are being made is dominated by larger block sizes (average block face of over 400 meters) • if the area in which the walkability improvements are being made consists of largely gated or walled superblocks (average block face of 600 meters or more)

  26. TEEMP Models – Walkability Improvement Projects • Scorecard for assessing Walkability • Land Use Heterogenity (scaling factor) • if the area in which the walkability improvements are being made has a fairly dense mix of residential and active retail land uses • if the area in which the walkability improvements are being made has only moderate density and mix of residential and active retail land uses • if the area in which the walkability improvements are being made has low density or low homogenity of land uses • Interpolates the initial trip mode share and walkability score with final walkability score ( capping limit of walking trip mode share @ 50%)

  44. TEEMP Models – Metro/LRT The MRT emissions model captures the impact of Mass Rapid System on CO2 emissions by quantifying the construction, operation and traffic impacts of projected MRT users • Input Data Requirements • Construction Materials – Steel, Cement and Bitumen • Emission factor – g/pkm • Electricity grid mix for Calculation Emissions from MRT • Electricity Consumption (Mwh) by MRT • Ridership ( Base, Intermediate and future year) • Trip length of MRT users • Length of MRT line • Average stream speed • Fuel Economy Annual Yearly Improvement (%) • Fuel Economy (KMPL measured @ 50kmph speed) at Base Year • upstream effect of emissions due to fuel production • Gasoline and Diesel emission factors • Mode share of MRT users in BAU case • Average Trip Length of modes in BAU • Average Occupancy of Modes in BAU • City Trip characteristics • Fuel Split % of Vehicles • Motorized modeshift factor • Landuse factor\

  45. TEEMP Models – Metro/LRT Emissions from Construction are neglected in the CDM methodology NM0266. “These have not been included as other methodologies in the energy or industrial sector do not include them also, based on the argument that material demand resulting from the project is non-significant in relation to national production. A clear case is e.g. ACM 0002 where dams can be built for hydropower projects without requiring the inclusion of construction related emissions (cement basically) although these might be very large quantities. ACM 0002 chapter leakage: “The main emissions potentially giving rise to leakage in the context of electric sector projects are emissions arising due to activities such as power plant construction, fuel handling (extraction, processing, and transport), and land inundation (for hydroelectric projects – see applicability conditions above). Project participants do not need to consider these emission sources as leakage in applying this methodology.” In the context of consistency of methodologies and equal approach to projects independent of the sector in which they are realized the construction related emissions for MRTs are not included in this methodology.” http://cdm.unfccc.int/UserManagement/FileStorage/YT9N5JM6J96BINCTBA625V8RCOA4EP
