Environmental performance (EN)

Environmental sustainability is a precondition for successful mining and smelting operations. Boliden’s environmental strategy is based on three component parts: Environmental Impact, Resource Efficiency, and Credibility. These elements address the most important areas for Boliden’s licence to operate and our long-term competitiveness.


(Base year 2012)

Metal discharges to water   

Discharges of metals to water shall decrease by 25% from 2012 to 2018

Metal emissions to air   

Emissions of metals to air shall decrease by 10% from 2012 to 2018

Sulphur dioxide emissions   

Emissions of sulphur dioxide to air shall be reduced by 10% from 2012 to 2018

Carbon dioxide emissions   

The carbon dioxide intensity shall not exceed 0.77 tonnes of carbon dioxide per tonne of metal produced by 2018

Environmental accidents   

Boliden’s target is to have zero environmental incidents every month by 2018


Material environmental aspects

Some of the environmental aspects, such as energy, water, emissions, effluents & waste, compliance and transport, are directly connected to how we run our operations and whether we maintain stable processes that comply with our permits. Several aspects are linked and impact on Boliden’s overall performance and compliance. Other environmental aspects, such as materials, biodiversity, closure planning, grievance mechanisms and supplier assessments constitute material aspects as they impact external stakeholders, and determine Boliden’s licence to operate and ability to develop the business. Also reclamation work is important and by 2018, Boliden aims to have completed the reclamation of at least five prioritised objects out of 20 identified.

Performance in relation to targets - 2016

The outcome in 2016 is positive in the sense that discharges of metals to water significantly decreased during the year. Metal to water and sulphur dioxide are declining and developing in the direction that Boliden has identified through its Group targets.

In 2016, 17 (14) environmental incidents occurred. According to Boliden’s definition, these include permit violations and serious incidents, whether environmental damage occurred or not. Nine of the events dealt with discharges to water, either due to internal effluent treatment not working according to permit or unforeseen leaks due to weather conditions or from processes. Five incidents involved unauthorized air pollution. Two of the incidents were related to limits for internal waste streams, and therefore did not cause any direct influence outside the industrial area. None of these events are assessed to have been of a level of seriousness that caused lasting harm or significant environmental impact. One incident involved a violation of the Cultural Environment Act due to an ancient fireplace being damaged by a construction machine before it could be examined by archaeologists. Boliden was fined SEK 100,000 for the violation.
