Vaisala's environmental impacts

We regularly assess our environmental impacts as part of our ISO 14001 certified environmental management system and aim to continuously reduce the environmental impact of our product portfolio, business operations, and supply chain.

Environmentally friendly products

A significant portion of the environmental impacts generated by our products arise during their use. Our industrial products and solutions help our customers improve their environmental performance, and our weather measurement solutions support decision-making in society by providing a wide range of critical information.

The environmental footprint generated by products over their life cycle can be affected during the product design phase. Our product development process includes environmental requirements, and many of the required product qualities, such as energy efficiency, maintainability, and recyclability, are beneficial for the environment.

The updateability and modular design of many of our products, combined with our field services, extend the product life cycle, which typically ranges from a year to over 20 years. However, we are aware that the global scarcity of resources and rapidly developing environmental requirements call for us to improve our product design process continuously. In 2019, we have continued the development work in order to respond to new environmental requirements and to advance environmentally sound design.

To ensure that our products are safe for people and the environment, we set strict requirements during the product design process for the materials used in our products. Components are analyzed early on in the new product development process to ensure compliance. We systematically collect information about substances that REACH* legislation has defined to be of very high concern as well as about compliance with RoHS** legislation. We do this in order to enable the safe use and end-of-life treatment of products. We also select new suppliers carefully and ensure that they meet our strict requirements.

At the end of product life cycle, we advise customers to recycle the products in accordance with local best practices for electronics recycling or to return them to Vaisala for recycling.

* REACH = Registration, Evaluation, Authorisation, and Restriction of Chemicals
** RoHS = Restriction of Hazardous Substances in electrical and electronicequipment

SDG 12 Responsible production

Renewable energy and energy efficiency

We are committed to using 100% renewable electricity in our facilities by 2020. Even though our manufacturing sites in Finland and the United States are already using solar panels to produce clean energy, we still need to purchase most of our electricity from local energy companies.

93% of the electricity we consumed in 2019 came from renewable sources, mainly from wind power. The increased use of renewable electricity has reduced our energy consumption emissions by 90% compared to 2014 (Scope 2, market-based). In 2019, we also started to purchase data center services powered by renewable energy.

In the end of 2018, our production site in Finland joined the Finnish energy efficiency agreement for industries. According to the goals of the agreement, we improved our energy efficiency in 2019 by upgrading our HVAC system and building a heat recovery system to our cleanroom.

SDG Clean energy

Personnel’s climate actions and awareness

We listen to our personnel in environmental matters and encourage them to make environmentally friendly choices. In 2019, we organised two climate change-related information and discussion events, opened a channel for personnel’s suggestions related to climate action, as well as campaigned for sustainable workplace lunches and commuting. We have also created a plan for promoting sustainable commuting based on development ideas received from a commuting survey conducted in 2019.
