Pollution levels rising again:need big answers again
The challenge of convergence
Cities need to find solutions to air pollution, public health and climate impacts of motorisation……
More growth. More pollution. More travel. More oil guzzling and warming… A vicious cycle
Growth in passenger kilometers for different modes of travel
Other studies show by 2030-31 on an average, Indians will travel thrice as many kilometers as they traveled in 2000-01
Polluted and warming…….Strong co-relation between pollution and CO2 emissions and energy use in Indian cities
Source: CAI Asia, 2008
Look at Delhi
CSE study found that while air remains polluted, total heat trapping CO2 emissions load from vehicles is increasing
Cars and two-wheelers contribute as much as 60% of the total CO2 emission load from vehicles
Only in 5 years, (2002 and 2007), CO2 emissions load from cars has increased by 73% and from two wheelers by 61%.
Public transport buses contribute 20%. But buses carry several times more people and consume significantly less fuel and emit less per passenger
Why do we need to worry about motorisation?
Globally transport has remained the most difficult sector for climate mitigation
Transport sector emissions rising.

Consumption Production
Widening gap between crude oil consumption and production.
The great guzzle …..
-- Transport energy demand up at 1.2 times the GDP growth rate.
-- Transport uses nearly 40% of total oil. Oil use by vehicles in 2035to be six times that of the 2005 level.
-- Urban car travel use twice as energy on average as average urban bus travel; 3.7 times more than the typical light rail or tram; 6.6 times more than average electric urban electric train. -- Share of railways in freight down to 26%.
Cars threaten energy security and climateFuture CO2 increase from transport will be dominated by cars and trucks. (IEA)

Emerging evidence from round the world:
Delhi: Working population of Delhi, Noida, Ghaziabad, Gurgaon and Faridabad lose nearly 2.5 hours daily due to peak jams. (ASSOCHAM)
Mexico City: 20% of workers spend more than three hours traveling to and from work each day, and 10% spend more than five hours. (WBCSD)
Congestion cost: Economic cost of congestion 4.4% of GDP in Korea; 6% in Bangkok. (WBCSD) Road congestion costs in India can be as high as Rs 3000 to 4000 crore per year (CIRT)
Its grim. But we still have the chance……..we have a different message for the world….
We have the chance to grow differently….

Our vehicles need to be more efficient. But we will have to do a lot more….
CO2 Emissions from Transport in Asian Regions 2000- 2030
New ADB study shows that even after accounting for nearly 25% improvement in fuel efficiency transport sector CO2 will increase
Only efficiency is not the answerLesson from other regions
In UK, cars became more efficient; emissions increased as people bought more; drove more
Better technology x number of vehicles= pollution, congestion, warmingThe numbers negate all impact

Time to act……..
Transport infrastructure (roads, railway, airports) locks up enormous amount of carbonTransport infrastructure and per capita CO2 emissions in different countries
Source: WBCSD 2009
We have the chance to plan it differently……
JNNURM and other programmes can be leveraged to influence. Under JNNURM approved cost of transport projects (Roads, flyovers, etc) is nearly 2 billion dollars. Cities have planned additional investments……
Design roads and spaces sustainably …. Do not lock in carbon, energy and pollution…..
Our cities need upscaled transition
Avoid future emissions
Shift to sustainable modes of mobility
Our cities have begun to work with a variety of strategies……..
These are the early stages of infrastructure development……..Let us not repeat the mistakes
Take the busTake the bus…………Bus transport can make a difference…
BANGALORE: An increase in bus share from 62% to 80% saves equal to 21% of the fuel consumed in the base case. 23 per cent reduction in total vehicles; Frees-up road space equivalent to taking off nearly 418,210 cars.CO2 emissions can drop by 13 per cent. PM can drop by 29 per cent and NOx 6 per cent.
DHAKA: An increase in bus share from 24% to 60% saves fuel equal to 15 per cent of the fuel consumed in the base case. Frees up road space equivalent to removing 78,718 cars from the roads. CO2 emissions drops by 9 per cent. PM can drop by 13 per cent and NOx less than 1 per cent.
COLOMBO: A increase in bus share from 76% to 80% can save 104,720 tonnes of oil equivalent, or 3% of the fuel consumed in the baseline case. This means 5% reduction in total vehicles and freeing up of roadspace equivalent to removing 62,152 cars.
Cities are investing in buses
Delhi plans to add 5000 more buses; Other cities are buying buses
Cities want modern, convenient and even air conditioned buses
Industry has to build capacity to cater to this demand
Only increasing numbers will not help. Need reform in the bus sector …..
Revitalise the public bus agency Implement new model for private operations…
The Transition………Reallocate road space. More space to low carbon and clean modes. More space to urban majority
and urban poor…

Yes No No specific answer
We asked people on the corridor: Are you happy with dedicated lane system of BRT?
We heard the voice of urban majority…
88% of bus commuters; 85% of pedestrians and cyclists, 45% of cars ad two-wheelers said a resounding YES
We have seen the difference…..
Technical asessment of BRT at Chirag Delhi Junction during morning peak hours (Ambedkar Nagarto Moolchad) reveals:
-- Buses are 2% of all vehicles but carry 55% of people
-- Cars and two-wheelers 75% of the vehicles but carry 33% of the people
Bus Corridor has reduced the average travel time for the majority of the commuters on the corridor
-- Overall average travel time reduce by 19%-- For bus users travel time has improved by 35%-- For personal vehicles travel time has improved by 14%-- Journey speed for bus users: 19-21 km/hour-- Cars and two-wheelers: 14-18 km/hour
Pedestrian walkway in BRT corridor: Well designed, well maintained, and well surfaced. Disabled friendly. At grade crossings comfortable for old, disabled and visually impaired.
Our other advantage…Our cities are built differently. Dense, walkable, cyclable,….
Delhi Kolkata Bangalore Mumbai
-- High density, mixed land use, and narrow streets make our cities walkable-- In a typical city the core can just be 5 km across and easily walkable within a reasonable time. -- Studies show more than 40 to 50 per cent of the daily trips in many of our cities have distances less than 5 kilometers. -- These have enormous potential to convert to walking and non-motorised trips.

Important to understand the range of benefits of sustainable transportation
Other countries have begun to assess co-benefits of their transportation projects as a measure of success

Reform agenda in Indian cities can reinvent mobility
Indian cities have begun to work towards policies for low carbon and clean transportation. This will have to be enabled and scaled up.
Opportunity to provide scaled up alternativesPublic transportInfrastructure for walking and cycling
Reduce demand for travel and vehicle usageLand-use planningRoad pricingTax rationalisationParking policy and charges
Leapfrog technologyEmissions standards Fuel economy standards
Fund the transition: Create transportation fund. Enforce tax measures to reallocate resources efficiently and raise revenue. (Currently, taxes on public transport is 2.6 times higher.)
Global action on low carbon transportHow can low carbon transport be enabled under the global climate regime?
Transportation groups are coming together to debate and act on this: Global Partnership on low carbon transport; Bridging the gap initiative; Bellagio principles …….
Get transportation recognised as a key sector for mitigation in AWG on long term cooperation
Financial mechanism has not worked for low carbon transport. Reform it. Only 9 out of 4474 CDM projects are transport related. Only 2 registered – Delhi metro – To reduce 41160 tonnes C/year. TransMileno BRT: to reduce 246563 TC/year.
Reasons: Difficult to prove additionality; Difficult to prove change because of the project; widely dispersed emissions; CDM money too small for the total cost of transport project……
Demand for reform – Eg, take programmatic approach to allow a number of similar projects for scale and impact
Enable national and city action
Account for co-benefits
Need low carbon transportation for adaptation as well……..
So where do we go from here?
How do we partner in this change?
How do we build knowledge, capacity, will to change, resources and mindset?
Lets debate………….
