2GreenLogistics or Green/Logistics?
- Evocative concepts
- Origins in the environmental movement
- 1990s the decade of the environment.
- New market opportunities
- Recycling.
- Transport of waste.
- Possible convergence?

Convergence?
3Reverse logistics
- Management of reduction and disposal
- Reverse distribution
- Collection of damaged or unsold products.
- Recycling of used products.
- The manufacturer takes responsibility for
delivery as well as take-back. - Two reverse channels
- Recycling / reuse (back to the suppliers).
- Disposal (shipment of non-recyclable waste).

4How green is the logistics industry?
- Most important issues
- Reducing packaging and waste.
- Hazardous waste disposal.
- Solid waste disposal.
- Internal costs.
- Least important issues
- Congestion.
- Land use.
- External costs.

5THE PARADOXES OF LOGISTICS costs
- Driving down distribution costs
- Benefits are realised by the users.
- 1990-2000 (manufacturing sector, GDP)
- Distribution costs declined by around 13.
- Inventory costs declined by around 5.
- Environmental costs are externalized
- The environment or society at large pay the
indirect costs. - The logistics industry has largely escaped
governmental attempts to charge for
externalities. - Numerous subsidies.
- Trucking is less regulated.
- Some estimates put costs as twice the revenue
generated by vehicle taxation.

1960-2000
7THE PARADOXES OF LOGISTICS costs
- Hubbing and the land take
- Airports.
- Seaports.
- Distribution facilities.
- Hubbing and local access
- Road and rail connections.
- Channel deepening.
- High costs wholly or partially subsidized.
8THE PARADOXES OF LOGISTICS time/speed
- Logistics has given rise to two fundamental
features of the contemporary economy - Just-in-Time (JIT).
- Door-to-Door (DTD).
- Cycle time requirements down by 25 between 1990
and 2000. - Both favour use of the least energy efficient
modes - Trucking.
- Air.
9THE PARADOXES OF LOGISTICS reliability
- Service reliability is at the heart of logistics
- Delivery time.
- Delivery on-time.
- Breakage.
- Modal reliability
- Logistics systems use the modes perceived to be
the most reliable - Trucks and planes.
- The most energy-efficient modes are perceived to
be the least reliable - Rail and ships.
10LOGISTICS AND WAREHOUSING
- Inventory reduction
- 1980 50 of costs.
- 1990 44 of costs.
- 1999 36 of costs.
- While the manufacturers may achieve economies
- Inventories are in transit.
- More links are added to the production chain,
with more traffic movements added overall. - A form of externality.

12LOGISTICS AND E-COMMERCE
Supply chain
- E-commerce and supply chain management
- Traditional marketing involves consumers going to
shopping centres for their purchases. - New systems require large distribution centres on
the edge of cities from which small parcels are
delivered to customers. - The system uses the most polluting modes.
- Disaggregation of retailing can be expected to
lead to more tons/km. - Higher use of packaging, with concomitant
increase in waste generation.

Emphasis on trucking and air transportation
Application of logistics
More ton-km transported
Activities less spatially constrained
Energy consumption Pollutant Emissions Congestion
Space consumption Pressure on marginal land
14How will logistics become greener?
- Top down government intervention
- The industry claims that one of the fastest
growing cost of warehousing is compliance with
governmental regulations. - Labor and health regulations (training).
- Environmental regulations, mainly concerning
dangerous substances and fuels. - Congestion pricing, road pricing (US) fair
pricing (EU). - Recent trends show an attempt by governments to
internalize cots. - Diesel fuel Sulfur to be reduced from 500 ppm to
15 ppm. - Outcomes uncertain
- Policies may impact differentially on the modes.
- Contradictory policies between tiers.
15How will logistics become greener?
- Bottom-up, industry action
- Technology will improve the situation (to a
limit). - Fleet management, vehicle efficiencies.
- Attitudes will change greenness can become a
marketing tool. - Composite solutions
- Environmental management and audit systems
(EMAS). - Will the logistics industry adopt ISO 14000?
- Paradoxical situation
- Problems occur at all spatial scales, from the
local through to the global, so a political
response is inevitable. - There are hopeful signs of greener attitudes in
the industry.
