Introduction

Indicators are measurable aspects of organization, which provide summarized information on how theorganization is performing. For example, to assess a financial performance, the indicators such ascompany turnover, profit, and amount of products sold might be used.

Indicators can also be used to measure environmental impacts. Environmental performance indicators(EPIs) can show clearly how the organization is performing, and provide a firm basis for future targetsand improvements. Thus, Cellulosic Specialties at rnskldsvik, Akzo Nobel Surface Chemistrystarted to work on developing a set of performance indicators to reflect the progress on sustainabletransportation of goods and personnel.

The choice of indicators to describe the most important environmental impacts from transportation is

crucial to the quality of the report and its value to stakeholders. Our goal is to provide the readers witha clear and meaningful picture of the organization's environmental performance. To do this, we choseindicators that give a representative picture of environmental conditions, provide a basis forinternational comparison, and are simple and easy to interpret.

Four indicators were selected for the transportation to and from Cellulosic Specialties at rnskldsvik:

1. means of transport used;

2. energy consumption by the transport;

3. carbon dioxide emissions;

4. sulfur and nitrogen oxides emissions.

This year we compose the environmental performance report on transportation and present the datafrom 2001.

EPIs for transportation to and from Cellulosic Specialties

Unit Objective Comment

Means of transport used

million tonnes*km

%

To minimize the numberof trips using non-environmental friendlymeans of transportation

This indicator shows the proportion of trips carried out bytrain, truck and ship. Compare to other long-distancetransports, railway often is an environmentallyadvantageous transport system. This is true for Swedenwhere SJ trains run on green hydro power electricity.

Therefore, as part of companys environmental policy, aconsiderable effort to use environmentally friendlyelectrical trains instead of trucks for the transportation of

products from rnskldsvik to Gothenburg was made byCellulosic Specialties during the last years.

To choose environ-mentally friendly meansof transportation andreduce consumption offossil energy by transport

This indicator also provides information on the greenhousegas emissions and air pollutant emissions that are directlydependent on energy consumption.

Emissions of carbon dioxide

To reduce emissions ofcarbon dioxide to aminimum

This indicator measures the carbon dioxide emissionscontributing to global warming.

Emissions of sulfur and nitrogen oxides

kg SO2, NOx/tonne*km, year

To reduce sulfur andnitrogen oxides emissionsto a minimum

The indicator measures the sulfur and nitrogen oxidesemissions contributing to acidification. Nitrogen oxidesemissions also contribute to eutrophication.
