- A catalyst for socially, financially, and
environmentally sound solutions to the problems
of urban mobility
3EMBARQ
- Established as a unique center within World
Resources Institute in 2002, EMBARQ is now the
hub of a network of centers for sustainable
transport in developing countries. - Shell Foundation and Caterpillar Foundation are
EMBARQs Global Strategic Partners, supporting
EMBARQ projects worldwide - Additional EMBARQ supporters include
- Hewlett Foundation
- Netherlands Ministry of Foreign Affairs
- BP
- US AID
- Asian Development Bank
- Energy Foundation
- Blue Moon Fund
- US Environmental Protection Agency

TRANSPORT
6EMBARQs project motivations
- Reduce GHG emissions from urban transport
globally. - Develop a reliable, inexpensive methodology for
measuring and accounting GHG and criteria
pollutant emissions from transport projects. - Create a clear correlation between changes in
transport activity and resulting changes in local
and global emissions enabling policy makers to
understand the environment and health
implications of various policy options. Allow
decision-makers to use GHG and criteria pollutant
emissions reduction co-benefits as an additional
criteria for selecting transport projects. - Identify the fundamental limitations of existing
tools and approaches. Currently available tools
provide only accounting for changes in emissions
and do not establish a relationship between
emissions and traffic changes. - Apply results in EMBARQs partner cities and
elsewhere

8Why Count Carbon in Transport Projects? Depends
on Who is Counting
- Third Party Fundors (ADB, W Bank, etc.)
- Estimate CO2 implications of transport related
projects - Provide tools for local stakeholders, whatever
their reasons - The Mayor, Governor, or Prime Minister
- Verify non-binding commitments or just brag
- Guide transport strategy and investments
- The Transport Office or Air Pollution Office
- Reduced traffic and congestion on its own
- Reduced local emissions
- The World Carbon Community
- Element of national carbon restraint strategy
- Carbon reductions that can be sold or traded
CDM etc.
9Certainty Levels versus Costs
Costs
Carbon Market
Governments with binding targets
Governments with non-biding targets
Philanthropy
Certainty levels
The project team wants to tailor the tools
developed to the needs of the various audiences
and understand the relationship between costs of
estimating GHG and criteria pollutant emissions
and certainty levels.
10Types of Transport Projects
- Fuels and Vehicles
- Fuel switch and hybridization
- Switch to larger vehicles and better running
(BRT) - Engine retrofits
- Traffic Improvements and Modal Shift
- One-way streets and signal synchronization
- Transit upgrades (e.g. BRT system)
- Cycle paths
- Land Use and Planning
- Transit Oriented Development
- Pedestrian Zones
- Portland Ore. Style growth boundary
Transport Mobility Accessibility
11Focus on the Transport-Emissions Link
- Whats In and Relatively Easy to Measure
- Fuel use in project vehicles
- Changes in mode towards/away from project
vehicles - Emissions in construction/destruction of
vehicles/infrastructure - Whats Important but Hard To Measure
- Changes in traffic and km driven caused by
transport project - So-called induced demand
- Whats Important, but Harder to Measure
- Changes in emissions resulting from changes in
driving cycle - Whats not in, but Relatively Easy to Measure
- Changes in fleet fuels to lower carbon fuels
- Changes in fleet propulsion (i.e., to hybrids)
- Changes in other fleet characteristics affecting
fuel use/emissions

- For Integrated BRT Systems only
- Default vs. measured fuel use/emissions
- Fuel Use/Emissions of affected vehicles vs
universe - Role of technological change over time on car
emissions - Assumes Effects of non-project vehicles small
- Reductions in congestion/higher speeds (or VV)

development - Gruetter Bogota Transmilenio

20Hanoi CO2 Scenarios SummaryHans Oern, Thuan Le,
EMBARQ
- Start with JICA Sponsored 2020 Master Plan
- Transport model gives people, vehicle movements
in 2020 - Alternatives proposed showing impact of mass
transit - No calculations of fuel, local emissions, or CO2
present - EMBARQs Contribution
- Quantify vehicle-km, passenger-km from Master
Plan input data - Estimate emissions and fuel/km from various
sources, local experts - Apply ASIF model to transform veh.-km into
total fuel, emissions - Results Implications of Different Transport
Futures - Fuel bill for Hanoi 2020 under different
assumptions - Pollution and CO2 emissions loads from transport
- Model for comparing emissions/pollution
alternatives

24Queretaro BRT Proposal
25Queretaro CO2 Summary
- Start with Transconsulat Master Plan for BRT
- Recognized Quaos in Queretaro
- Examined overall transport situation
- Suggested at least 1 BRT route for emerging
corridor - Evaluate BRT Choices
- Numbers of vehicles, capacity, etc
- Emissions and fuel use of choices from MC tests
- Some information on existing fleet fuel use
bolstered by MC tests - Results BRT Alone Small Improvement
- Most emissions continue to come from feeders and
others - Greater effort to substitute larger for smaller
vehicles needed - In any case, BRT canceled for budgetary reasons

35Lessons Learned So Far
- Project-Based Vehicle Emissions Changes
- Easy to measure and verify
- Can be large before/after but small relative to
entire region - May be less than 50 of entire savings in
project - Other Emissions Changes Difficult
- Poor data on present and future traffic and
people/freight flows - Very poor data on fuel intensity and emissions of
vehicles - Difficulties estimating counter-factual case
- Larger issues and Caveats
- Dont let CO2 drive good transport decisions
- Do verify that CO2 is less than otherwise
because of a project - Weigh transport plan choices against CO2, local
emissions changes
