24 TEEMP Models – Walkability Improvement Projects The savings are calculated in two stages 1.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. 2.the improvement scenario i.e. after the project i.e. walking trips % share in the total trips will rise through time. Input Parameters 1.Project Lifetime (Number of Years) 2.Starting Year Total Number of Trips/Day 3.Annual % Increase in Total Trips/day 4.Mode Share 5.Average Trip length 6.Emission Factor 7.Mode share deterioration due to no improvement/ annual decrease in walk trip share 8.Increase in walking trips due to improvement/ before and after walkability ratings/ annual increase in walk trip share

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 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.” TEEMP Models – Metro/LRT http://cdm.unfccc.int/UserManagement/FileStorage/YT9N5JM6J96BINCTBA625V8RCOA4EP

52 52 TEEMP Models – Roads (Expressway, Rural and Urban) 52 “The basic impact of construction is due to new trunk lanes being built for the BRT project. The emissions occur during production of the required building materials, and are thus upstream. The methodology focuses solely on cement and/or asphalt as the main energy-intensive materials used for construction. “ CDM - Approved baseline methodology AM0031 1. SARD Carbon Footprint Model (draft) ~ 2115 tons/km 2. Life Cycle Analysis of Highways by Park et al. ~ 2438 tons/km ( 4-lane) 3. Sightline Institute LCA for 50 Years = 2175 tons/lanekm 4. Mickleham Rd – Vic Roads = 760 tons CO2-e / km 5. Deer Park Bypass Estimate – Vic Roads = 4,870 tons CO2-e / km Source : Carbon Footprint Model(draft), Sightline Institute, VIC Roads and Kwangho Park et al. Some Examples Emissions during construction

53 53 Without improvement traffic would never grow after a certain limit!. To capture this impact capping limit for saturation has been proposed. The analyst can evaluate impact @ V/C = 1,1.5,2, 2.5 etc. TEEMP Models – Roads (Expressway, Rural and Urban)

55 55 TEEMP Models – Roads (Expressway, Rural and Urban) Emissions are dependent on speed, thus using the highway capacity analysis; first the model establishes the V/C (Volume Capacity) Ratios. Using the insights on speed-flow equations from the Updated Road User Cost Study (IRC-SP, Manual of Economic Analysis of Highway Projects), the China Green Transport Project and the Bangalore Metro Study, an impact of V/C on speed was quantified.

58 58 TEEMP Models – Railway Sketch Analysis 1.This requires activity data and emission factors 2.default values has been provided for infrastructure construction emissions. 3.The analyst is able to evaluate the emissions saved based on “high level” and “low level” indicating various degree of efficiency based on international literature review. 4.Analyst can compare Highways with Railways to check the feasibility of emissions savings (compatible with highways model) 5.Analyst can check various degree of shift from road to rail… Input Data Base Year Passenger-km or ton-km Number of Passengers and Average Trip Lengths Emission Factor - g/PKT/ g/tKT, mj/PKM or mj/TKM Quantity of construction materials - Number of rails per km, Weight of rails per km, Number of sleepers per km, Number of fish plates per km of track, Number of fish bolts per km of track, Number of bearing plates per km of track, Number of dog-spikes per km of track, Quantity of ballast required for B.G, number of stations and bridges, quantity of steel, concrete and copper etc.

59 59 Example – Expressway in VietNam (ADB) TEEMP Models – Railway Sketch Analysis

60 TEEMP Models – Limitations 1.Quality of the model structure is not uniform across models. ( ex MRT/Roads) 2.Needs “live” applications and a mechanism to improve the defaults and sketch analysis ( ex Bike/Walk scorecard) – need to train models with good data 3.Outputs depend on quality of input. Needs better data to estimate impact accurately ( ex emission factors) 4.Benefits such as “Value of travel time”, “fuel savings” and “Accident savings” are still not included 5.Detailed traffic model outputs are required for detailed analysis 6.After assessment what? – TEEMP does not answer this – economic analysis? Cost effectiveness? 7.TEEMP misses “freight”
