The environmental impacts of Wärtsilä's operations largely relate to manufacturing. The main environmental aspects of manufacturing relate to the use of energy and natural resources and thus also to the emissions that are produced by the manufacturing processes. Product development also requires the testing of products and individual components which, alongside manufacturing, loads the environment. However, the positive impacts of product improvements on the environment far outweigh the negative impacts of testing when taking the product's entire lifecycle into account.
The main reasons for significant fluctuations in certain reported environmental performance indicators from year to year are:
- changes in production volumes
- changes in R&D testing programmes
- changes in company structure (divestments, mergers & acquisitions)
- changes in the reporting scope and coverage.
The environmental indices used in connection with performance indicators are linked to the development of net sales. Therefore, increased investments in R&D during any particular year do not impact net sales but may increase the absolute value of the indicator.
Monitoring environmental impacts
Within Wärtsilä, environmental impacts caused by operational activities are monitored as follows:
- participation in the monitoring of air quality with other local stakeholders
- measurement of air emissions
- charting of noise levels
- periodical effluent analysis
- soil analysis
- dispersion analyses and bio-indicator surveys.
