trade and the construction industry. (Ogden, 1992;
Ministry of Transport and Communications, 1999)
The main rush hours of grocery deliveries are at the
same time as the passenger traffic rush hours,
between 7 and 9 a.m. (Ministry of Transport and
Communications, 1999). An important consequence
of the development of logistics, electronic commerce
and telecommunications is the consolidation options
for deliveries of different suppliers, which can lead
to higher load factors and less vehicle mileage.
Consolidation entails planning the logistics services
to respond to the customer demand and consumers’
consumption habits.
The structure of economic life, urban form, and
the demand for delivery transports has recently
undergone changes which have been anticipated to
continue. The changes are partly due to changes in
the logistics structure, for example JIT (just-in-time)
warehousing and supply chain management
strategies, which have decreased warehousing and
increased delivery frequencies. Electronic commerce
has been anticipated to increase the delivery
frequencies and direct them partly to end-users,
which implies new challenges for delivery planning.
Changes in the operating environment increase the
complexity of delivery models and also shorten their
lifespan (D’Este, 2000).
The supply chains of products have traditionally
been planned to have on direction; the purpose has
been to integrate the process from raw materials
acquisition to the final product delivered to the end-
customer. Several approaches have been developed
for this purpose, for example SCM (Supply Chain
Management), ECR (Efficient Consumer Response),
and the networking strategies attached to these
approaches. Nowadays an assessment of
environmental effects is part of almost all production
processes and many companies have developed
environmental management systems to be able to
evaluate environmental effects comprehensively.
The concept of green logistics includes
environmental impact assessment in each part of the
supply chain and completes the logistical chain with
reverse logistics including recycling and reusing
flows of products, by-products and, for example,
packaging materials. The purpose is to reduce
transport demand with, for example, by planning the
packages and distribution channels and taking the
market area into account in locating the production
facilities. Green logistics is geared towards the
development of environmentally friendly products
and production methods. (Wu and Dunn, 1995)
The increased use of information technology in
logistics and leaner production and warehousing
strategies has increased the customer requirements
for time, precision and flexibility of deliveries.
Growing accuracy and time requirements may
increase the demand for vehicle mileage and lead to
customised deliveries, where a small delivery batch
is transported directly to the customer. Increased
requirements may therefore increase the
environmental effects and costs, especially in the
distribution chain of the retail grocery trade, where
the share of transport-related environmental effects
is already relatively high.
IPCC (2007) defined the increasing demand for
freight transport as one of the most important target
areas in the reduction of carbon dioxide emissions
from transport. The energy consumption of transport
has been predicted to increase, especially in aviation
and shipping. As the globalising markets and
logistical trends promote the increase of
international freight transport demand, information
society applications also affect the energy supply
and climate change objectives.
2 FINDINGS
Changes in the business environment and production
structure affect the demand for goods transports.
Manufacturing industries are mostly transport
intensive business areas, where a cost-effective and
reliable transport system is one of the most
important requirements. Electronic data transfer and
the fast development of information technology have
markedly affected the business environment in the
last ten years. This development offered an
opportunity to use and improve increasingly
effective business control systems and increased the
amount of real-time information and therefore more
dynamic business processes.
As the markets and operations of companies are
becoming more global, production and logistics
structures are planned on a new basis. Production
processes have also become more focused as
companies retain the same number of plants but
increase the degree of plant specialisation.
At the moment there are several potential
business models in e-commerce. Usually companies
use Internet-based services as electronic shops. E-
commerce solutions are used increasingly as
effective marketing channels. Business-to-customer
solutions have attracted a lot of attention in recent
years, but they still have a relatively small, although
increasing, role in the market. The use of business-
to-business solutions are more advanced and trading
between companies has partly moved to the Internet.
