Modulight’s key environmental themes are energy efficiency in products and production, high standards of material management and reducing the environmental impact of its operations.

For heating, district heating has been used, and electricity used is wind-certified and renewable. The energy intensity of Modulight’s production and the life cycle of the products is low. Emissions from production are mainly caused by heating and electricity consumption of the production and office space, as well as gases used in production.

Modulight’s production facility has been modernized and expanded. Production efficiency has improved, and the product range has expanded. Modulight has calculated its carbon footprint excluding Scope 3 emissions during the use of products. In 2023, total emissions were 725 t CO₂e (606 t CO₂e in 2022). The main emission source was business travel, especially flying, with 53% of total . Flying is a necessity for Modulight in reaching the international customer base, but low-emission ways of traveling are preferred, and  discussions and meetings are organized remotely, when possible. In everyday commuting, many employees prefer cycling, walking, and public transport, because Modulight’s office has good traffic connections.

Modulight compensates the emissions of its own operations through participation in the Gold Standardised wind power project in Madhya Pradesh, India. Modulight estimates that the most significant emissions come from the supply chain, and the share of own operations is only less than a tenth of the total emissions.

Raw materials used by Modulight are metals, chemicals, and semiconductors. For example, the metals used in the semiconductor process have been 100% recycled for more than 20 years, and precious metals used, such as gold and platinum, are 100 percent recycled. Nitrogen is also used in production, both as a pure gas and in liquid form.

Controlling production quality is part of reducing environmental impact. Modulight is certified to the ISO 14001 environmental standard, and resource efficiency in production is being continuously improved. Relatively little waste is generated, and recycling is at a high level. Efforts are made to minimize the consumption of harmful chemicals, for example by reusing them as much as possible. Unusable chemicals are delivered for disposal when they can no longer be used. The amount of waste and effluents is very small, less than one percent of total emissions. Modulight also has the WWF Finland Green Office certificate, which shows the company’s long-term work in reducing the carbon footprint and consumption of natural resources.

The reduction of the impact of carbon dioxide emissions on the climate requires action. In the spring of 2023, Modulight made a far-reaching and responsible decision to give up district heating and to invest in a geothermal system. The project was started right from the beginning of autumn.

The investment is estimated to pay for itself in approximately 10 years. Carbon dioxide emissions from district heating have been about a fifth of Modulight’s total emissions, so the change will significantly reduce the environmental impact of the operations. Geothermal heat pumps use a relatively small amount of electrical energy compared to the heating energy produced, but when Modulight uses fossil-free wind electricity certified in accordance with the guarantee of origin system, the calculated emissions from heating drop to zero.
