Sustainability

Environmental responsibility. Measured, managed and improved.

At comemso, environmental responsibility is connected to an ISO 14001 management system, operational measures and published data. Renewable electricity, on-site solar generation, efficient buildings, fleet electrification and resource control are treated as an ongoing engineering task.

Our approach

Sustainability is a controlled improvement process.

The goal is not to isolate one attractive measure. Energy, mobility, buildings, materials, waste, people and legal obligations must be managed together and reviewed over time.

Generate and procure renewable energy

Use electricity from the company’s own PV systems first and supplement it with certified renewable electricity.

Reduce operational demand

Improve heating control, insulation, lighting, equipment selection and monitoring of major electrical consumers.

Electrify mobility

Operate a predominantly electric vehicle fleet and use AC and DC charging infrastructure in daily work and product development.

Measure and disclose progress

Track energy, water, materials, waste and emissions, then publish the results and the next improvement priorities.

Published environmental data

Progress becomes credible when the baseline stays visible.

The Environmental Report 2025 publishes comparable operational figures for 2021 through 2025. The values below show the reported start and current endpoints.

External electricity

274,845kWh in 2021
55,469kWh in 2025
about 80% lower

Gas

206,225kWh in 2021
90,005kWh in 2025
about 56% lower

Water

280m³ in 2021
146m³ in 2025
about 48% lower

Reported operational CO₂

42.17t in 2021
19.63t in 2025
about 53% lower

These figures are taken from the published report and describe reported company operations. Production volume, material use and high-power test demand changed during the period. They are not a product life-cycle assessment.

Energy and buildings

Produce more on site. Reduce the demand behind it.

PV systems on both company buildings were installed and commissioned in 2022 and 2023. Storage capacity and additional façade-mounted PV modules were expanded through 2026 to increase self-consumption and improve winter generation.

The remaining electricity demand is covered with certified renewable electricity. The newer building uses heat pumps. In the existing building, heating controls, thermal separation and high-insulation windows reduce gas demand.

PV

Solar generation

Roof and façade systems across the existing and new buildings.

100%

Renewable purchased electricity

Certified renewable electricity supplements on-site generation.

HP

Efficient building systems

Heat pumps, improved controls, insulation and monitored consumers.

BAT

Higher self-consumption

Storage expansion supports more effective use of incoming solar energy.

Operations

Environmental impact is managed beyond electricity.

The report connects energy decisions with mobility, production materials, waste, water, hazardous substances and purchasing.

EV

Predominantly electric fleet

The report lists a fleet dominated by electric vehicles, with two diesel vehicles remaining in 2025. AC and DC charging stations support both operations and product testing.

MAT

Materials and recycling

Material input and waste remain measurable. Suppliers are addressed on take-back and recycling of sorted production plastics where feasible.

H₂O

Water and substances

Water use, cleaning agents, solvents and other relevant substances are tracked. Substitution opportunities for hazardous substances are reviewed regularly.

Transparency includes limits.

The report also explains why 2025 operational CO₂ remained close to 2024, including the use of a specialised field-calibration transporter. Progress is documented without hiding the operational trade-offs behind it.

Environmental management

Responsibilities turn intentions into repeatable action.

comemso’s environmental management includes a permanent environmental officer, employee training, internal participation, recurring audits and documented legal-compliance checks.

01

Defined responsibility

An environmental officer reviews processes independently of day-to-day production responsibility.

02

Employee participation

Training, information and an internal suggestion system support continual improvement.

03

Audits and compliance

Internal and external audits, safety structures and legal-conformity checks keep obligations visible.

04

Measurable objectives

Future priorities include reducing external electricity demand, increasing solar self-consumption and keeping emissions growth below company growth.

Environmental Report 2025

Read the data, measures and remaining priorities in one document.

The German-language report documents the environmental strategy, measures from 2015 through 2025, operating data for 2021 through 2025, management responsibilities, objectives, occupational safety context and legal compliance.
