Contributing to the environment

We constantly work towards reducing our environmental load generated in our operations. We reduce water and energy consumption, emissions and waste in our production.

Environmental footprint of our products and services

A relatively small portion of the environmental footprint of our products and services is created in our own production but are rather created in our value chain. As the volume of our production outsourced to our subcontractors increases, the relative significance of our own production further decreases.

The most essential environmental impacts of our production are related to energy consumption at our foundries. We constantly strive for improvements in our energy and materials efficiency and in reducing water consumption, emissions and the amount of waste in our own operations. We have also identified environmental risks related to our operations, and we practice precautionary procedures to prevent environmental accidents.

We have set Group-wide targets for energy-saving and CO2 emissions, as well as for water usage and the amount of waste going to landfill. We also have created a target for environmental accidents. Our target is zero environmental accidents.

The biggest share of the environmental footprint of our products is when in use, and therefore, we constantly focus on developing more eco-efficient technologies. The availability of the earth’s resources is already having a strong impact on our customer industries. With our technology, we are able to provide solutions for our customers to support their challenges.

The second biggest environmental impact is produced by our supply chain. Metso’s aim is to minimize environmental impacts throughout its value chain, so the significance of understanding and measuring the impacts in the value chain increases. Efforts are made to develop methods for calculating and understanding the environmental impacts of our supply chain.

Reducing waste

The waste at our operating sites includes metal, wood, cardboard, paper, municipal waste and foundry sand. The amount of waste is been reduced by focusing on landfill waste and by increasing recycling. Waste is recycled in compliance with local regulations and whenever possible.

We have set our target of a 15% reduction in the amount of waste going to the landfill by 2020. We encourage our production units to take measures to avoid the formation of waste in the first place and to increase the utilization of waste already generated.


Water-saving efforts

The water usage in our operations is not significant. Water is used mainly for catering and sanitation purposes, and for cooling in our foundries. For cooling purposes, we use surface water, which is returned back to its source without causing any severe impacts on the environment.

Metso, however, operates in 50 countries around the world, including water-stressed areas and in recent years, we have focused on water-saving efforts, especially in the water-scarce areas. Our largest water-consuming plants in water-stressed areas are located in India, China, South Africa and Mexico. In these countries, we have initiated various actions to save water, such as checking water meters daily for abnormal consumption and reporting on a monthly basis to ensure early detection of any leakages.

We have set a target of a 15% water usage reduction in our own operations by 2020. Currently, we have created the cornerstones for a Group-wide water strategy, which will be further developed. In addition, we have ongoing projects that map water-related risks using the WWF’s Water Risk Filter tool.

Metso also monitors different wastewater components wherever necessary for environmental reasons. Generally, our discharge to water is minor and not considered relevant in Metso's operations.


Metso’s Energy Efficiency Program

The most essential environmental impacts of our own production are related to the energy consumption in our foundries. We strive to reduce the environmental footprint of our own operations through a dedicated energy-efficiency program while setting global, Group-wide targets for energy conservation and carbon dioxide emissions.

Our global target is to reduce Metso's energy consumption and emissions by 20% of our total business volume by 2020. The majority of our reported CO2 emissions derive from the use of energy. Therefore, decreasing energy consumption will also reduce emissions – while also creating financial savings.

We have been mapping the opportunities to save energy and decrease CO2 emissions in our most energy-intensive production units, our foundries. We have developed quarterly reporting metrics for each production site, and we conduct energy audits at the sites with the highest energy consumption and the greatest potential for energy savings.

The most significant savings in our own production lie in the utilization of fuel, such as natural gas and heat. We have defined energy-efficiency indices for our production units, which report their energy consumption on a quarterly basis. This supports energy efficiency and monitoring at the Metso level. 

Potential savings are also identified outside the production process, for example in cooling, compressed air systems and building services. Since the beginning of the program in 2009, a total 12.6%, i.e. a total of 51,000 MWh of energy (16,908 tons of CO2) has been saved through a wide range of actions.

Understanding our scope 3 emissions

Outsourcing selected parts of the manufacturing process emphasizes our responsibility for the environmental efficiency of our subcontractors and suppliers. We have conducted annual scope 3 carbon-dioxide emissions calculations since 2013 to better understand the environmental impacts of our supply chain.

Scope 3 is one of three reporting categories measuring greenhouse gas emissions. The first emissions category measures direct emissions and purchased fuels, and the second category measures indirect emissions, such as purchased electricity and heat. The third category concentrates on other indirect emissions, such as employee business travel, contractor-owned vehicles and outsourced activities.  

The assessments have identified five relevant scope 3 emission categories: use of sold products, purchased goods and services, both upstream and downstream transportation, and business travel.

The reporting of emissions related to business travel is already an established practice at Metso. Emissions for transportation and purchased goods and services have been calculated and reported for limited external use. Emissions from the use of sold products cannot be calculated with sufficient accuracy, due to the long life cycle of Metso’s products and the high variation in product use patterns. Therefore, they are not reported. Instead, Metso focuses on analyzing the CO2 emissions and other environmental impacts of individual products and on customer cases.

We continue to develop methods for calculating and understanding the environmental impacts of our supply chain. This will enable us to better manage the environmental impacts of our supply chain and other processes beyond our direct control.
