Transportation decision making often occurs with indicators determined from a subset of system processes: “tailpipe” emissions are the majority of emissions
the majority of impacts result from “tailpipe” emissions.
More and more we are recognizing the shortfalls of this limited view
Life-cycle assessment affords us an opportunity to evaluate the larger footprint

levels of public transit and more compact patterns of land
use that transit supports

Sustainable Transportation Systems
Metro is at the forefront of developing a fully integrated
sustainable transportation system:
Safe and easy to use
Accessible and affordable
Efficiently operated
Interconnected with diversified choice of
transportation modes (bicycle, car-sharing, public
transit)
Our objective is to optimize transportation services to
increase throughput, safety and security while reducing
energy and emissions

The impacts of the transportation system extend beyond the tailpipe, to include: Manufacturing Roads, parking and other infrastructure Maintenance Fuel production
To meet the State’s aggressive environmental goals we must
understand and transform all phases of the life cycle Could changing fuel standards have unintended consequences? Could manufacturing new buses increase net emissions? How does reducing GHGs effect air quality?

What are the life cycle effects of 3 different transportation options in Los Angeles?
How could LCA be integrated into transportation decision-making across the state? An analysis of policy options A survey of transportation professionals Creation of a user-friendly LCA tool for transit agencies
Tailpipe emissions create 40% of statewide GHGs. Including the LCA effects of the transportation systems shows the real impact is much higher.

Basic issues
1. Fragmentation of
transportation policy
2. Spatial and temporal
scope of LCA
3. Mismatch of incentives
4. GHGs vs. criteria air
pollutants
![Page 46: American Planning Association April 15, 2012media2.planning.org/APA2012/Presentations/S428_Life Cycle...Image source: Los Angeles Metro. American Planning Association April 15, 2012](https://reader030.fdocuments.net/reader030/viewer/2022041114/5f22141a4d7fd451ce57fd54/html5/thumbnails/46.jpg)
Features of good policy
1. Affect wide swath of policy process
2. Allow comparison across modes
3. Spatial scale similar to scale of impacts
4. Realistic analytical burden
5. Realistic for agency/political capacity
6. Avoids unnecessary social costs

Possible policy structure #1
1. Legislation requiring lowest-life-cycle-
impact projects
Pros: explicit requirement; wide coverage of major
projects; even playing field across jurisdictions
Cons: analytical burden; impact on other selection
criteria

Possible policy structure #2
2. Preferential funding program (a la CMAQ)
Pros: financial incentives; opt-in structure
Cons: may not affect enough projects; difficult to
obtain sufficient funding

Possible policy structure #3
3. Planning standard for Regional
Transportation Plans
Pros: allows comparison across modes
Cons: not fully comprehensive; RTPs still rely on
local general plans for land use

Possible policy structure #4
4. California Environmental Quality Act
criterion
Pros: natural home for analytical work; EIRs not
geographically constrained; mitigation potential
Cons: project-by-project analysis; limited
opportunities to modify projects significantly

Possible policy structure #5
5. Transportation Control Measure selection
under Clean Air Act
Pros: natural fit for analyzing criteria pollutants;
strong regulatory incentive for qualifying projects
Cons: does not affect projects not identified as
TCMs

Possible policy structure #6
6. LCA “cap-and-trade” for regional and local
transportation agencies
Pros: allows comprehensive analysis of whole
region; allows planning flexibility; could allow for
trading
Cons: potential administrative complexity
