India Transport Emissions – 2007 – Quantifying emissions without reliable data


Sudhir Gota

You simply cannot generate reliable emission estimates without accurate data. In fact, I would not hesitate to claim that “Without reliable data, transport emissions forecasting is as good as “fortune telling””. You need to consider the numbers with a pinch of salt or many a times consider the estimates as only numbers!

The reason why I am coming up with such an argument is because yesterday India released its 2007 Green House Gas inventory. I think it has some big problems with the transport estimates. It claims that the “road transport sector emitted 123.55 million tons of CO2e, which is 87% of the total emissions from the transport sector. The transport sector emissions include all GHG emissions from road transport, railways, aviation and navigation. It suggests that “the total number of registered vehicles in the country has increased from 5.4 million in 1981 to 99.6 million in 2007. Two wheelers and cars constitute nearly 88% of the total vehicles at the national level”.

The problem with the total numbers of vehicles in India is that registered vehicles cannot be used for estimates as we don’t have active scrappage/renewal system. Not many people have an idea as to how to guess the number of vehicles on road. Even the activity information (vehicle travel/year in km) is not available on public domain and often people borrow the numbers from some isolated studies and from other countries or other researchers.

In order to highlight the data issues, following are some of the critical issues


1. Vehicles

a. No breakdown by mode type and engine technology (e.g. Euro 1 or Euro 2 compliant, etc.)

b. limited data on active vehicle fleet

c. No data on splitting small cars with big cars, MUV’s, LCV’s

d. Isolated surveys to determine age of the vehicles

2. Fuels

a. No fuel split available - gasoline, diesel, alternative fuel

3. Activity

a. No data on urban vs rural share of movement

b. Occupancy – how many people/load

c. Annual surveys and proper methodologies on vehicle-km travelled, passenger-km travelled, and tonnes-km rarely exist

d. Reasonable data on fuel consumption per km travelled on various transport modes. This issue is critical as quoted values from lab testing differs from actual on road values

4. Emission factors

a. lack of locally representative emission factors for existing vehicle fleet

Coming back on the India’s 2007 estimate of 123 million tons in 2007 for an activity information of 99 million vehicles is too low as seen from the below graphic. In fact the estimates of CO2 /vehicles is lesser (1.2) than what researchers have quantified for passenger transport (ratio of 1.5 for passenger vehicles. Including commercial vehicles in estimation would expand this figure to a range of 2 to 4).

Strangely, the same authors, in an earlier study had quantified 106 million tons in 2000 with 48 million vehicles. Then why is that the doubling of vehicle numbers not showing impact?

One thing that hits hard in the below graphic is the huge variation of CO2 and vehicles. It seems that researchers do not agree with each other … a classic case of elephant and the blind men !!

Cartoons as a Mass Communication Strategy for Sustainable Transport

Sudhir Gota

The first thing most of us often notice in the newspaper is the editorial cartoon – an art of the moment drawn to illustrate message in a comic way. The illustrations often reside in our memory for a long time and thus newspapers use cartoons as a means to provide the knockout punch – to create an immediate impact among the audience.

This benefit of quick impact provides huge potential for educating masses on sustainable transport issues. To initiate the paradigm shift, a huge effort needs to be made in changing the mindset of transport consumers and policy makers. Cartoons in newspapers can provide the not only an easiest way of reaching vast segment of audience– educated to non-educated, children to elders, urban and rural people etc., but also creating lasting impact in few seconds.

When editorial cartoons are supported by think pieces written by editors, policy makers and experts, it creates the momentum at the grass route level thereby increasing the support for the paradigm shift in transport. One needs all the support when trying to create solutions by attacking the demand and breaking the trend of using infrastructure as a magic bullet.

Take the case of Ahmedabad BRTS, where media played a constructive role in highlighting various issues related to BRTS, educating the people and providing constructive criticisms which enabled it to become a best practice BRT in Asia. Without media support, things become very difficult for policy makers and political support for radical actions often evaporates.

In order to capture as to how newspaper cartoons can create lasting impact, transport cartoons from times of India newspaper (TOI) from India where collated from the period January-2008 till now. This newspaper is extremely popular in India and supposed to have the largest circulation among all English-language newspapers in the world. According to some estimates it has a print readership of 13.3 million and its online version reaching a record 159 million page views in May 2009. Scanning through 840 newspaper editions though is a time consuming process, extracted collection is very impressive with many transport related stories being told with simple images.

Studying the cartoons from last early 2008, fuel prices and congestion has been the favorite topic of the artists. In 2008, newspapers used cartoons many a times to create awareness on fuel consumption and rising fuel prices. Climate change and COP discussion was another favorite topic during 2009. Many cartoons were localized to suit domestic audience to create greater impact and many also relied on quotes to add the punch. The stories were conveyed from the perspective of common man.
Though, few cartoons took potshots against Delhi BRT, many were highlighting the poor pedestrian infrastructure. Surprisingly, considering very high accident fatalities, not many cartoons highlighted the road safety aspects.

Please find some of the collection below. Please source all the cartoons to Times of India and do send them positive feedback and request for more transport related cartoons @http://epaper.timesofindia.com/index.asp. Many a times such efforts can create lasting impression and thus resulting in better outreach.

Use light colored clothes at night. You would want motorists to see you - wouldn't you?

Sudhir Gota

Innovative thinkers in Transport sector have not yet established the relationship between the color of clothes, walking and its impact on fatality. But, there are some who have found the answer to reduce pedestrian fatality.

Pune Traffic police in India advices pedestrians and cyclists to follow particular instructions -

1. Use light colored clothes at night. You would want motorists to see you - wouldn't you?

2. If there is no footpath, walk facing the oncoming traffic.

3. The only right of way is the one the other Driver/Rider gives you, especially the one who is Bigger/Heavier.

Check out Pune Traffic Police website (http://www.punepolice.com/TRAFFIC.html#some)

I have always wondered why such kind of advice is given to pedestrians and cyclists without even thinking about the infrastructure for them.

What ails us?

What’s wrong with our system which implements laws such as jaywalking but cannot even provide accessible crossings or footpaths?

My questions were partly answered previous week when we hosted one of the leading proponents of good transport – Prof Madhav Badami in Manila.

During our interactions, Prof was adamant that “Windshield view” of the policymakers and media people was the main cause. His actual quote was - “Most who WALK don’t have a SAY, Those who have a SAY, don’t WALK “

During the brownbag in ADB, he built a case for restoring pedestrian accessibility. Harping on the “Restoring” issue, he argued that Asian cities which had the natural advantage for walking have lost it due to illogical policies and thus facing all sorts of problems. Lamenting on the current trend of use of quick fix (flyovers) and/or ornamental solutions (providing expensive, inappropriate options when not required) he questioned - Is it that we do not know; we can’t do; OR we simply don’t give a damn…..

Prof indicated that the current problems are iatrogenic in nature and if we don’t act now, it would be too late. Prof in order to illustrate his case took the audience on an India Photo tour and narrated his experience while taking the photos. The audience was appalled on seeing the bad state of pedestrian infrastructure and the interconnectivity of walking with public transport. Prof showed how high cost intensive metro’s neglect walking facilities while promoting park and ride.

Prof used the terms “seamless connectivity” and “refuse distance” many times to indicate the importance of changing the mindsets from only footpaths to many other aspects of pedestrian facilities.

Inspired by his speech, a gentleman from ADB’s finance division questioned back – is there no hope?

I knew the answer – there is lot of hope in Asia. We are not yet motorized to the extent of developed countries. We need to only shift and scale-up the investment to stop migration of people and in modes… and to do this as Bert Fabian puts it – “everything is in the mindset”.

We need to change mindset of people and cities would follow.
