Climate protection

LEONI considers global climate change and the related, mounting statutory and economic demands to be part of corporate responsibility. As a preferred partner in the market for climate-friendly and resource-efficient mobility, one focus is on climate neutrality and the efficient and sparing use of resources at all locations and along the entire value chain. The biggest causes of scope 1 and 2 emissions at LEONI include energy sources used in generating power for our production facilities and logistics. LEONI intends to remain an attractive supplier for its customers and to contribute to the mobility transformation with efficient use of renewable energy and environmentally friendly transport.

"We are taking measures at our sites all around the world on an ongoing basis in order to lower our energy demand and to cover it in a climate-friendly way."

LEONI has calculated a reduction plan in order to reduce its scope 1 and 2 emissions and to achieve the 1.5 degree target. Accordingly, we aim to save 17% in emissions by 2025 and 38% by 2030 (compared to the baseline year 2021). Through continuous reduction measures, LEONI plans to cause 90% fewer emissions by 2050 when compared with 2021. In order for LEONI to become climate neutral (scope 1 and 2) between 2035 and 2040, from 2035 onwards emissions that cannot be saved will be offset by certificates. The targets for 2030 and 2050 are based on scientific calculations and are aimed at achieving the 1.5 degree Celsius target.

Key sustainability issues: 

  • Renewable energy and energy efficiency
  • Environmentally friendly transport

Overarching goal:

  • Reduction of emissions aligned to science-based targets


As a key target, LEONIs ReWire defines measurable steps on the way to achieving a 90 percent reduction in the Company's CO2 emissions by 2050 compared with the baseline year of 2021 – guided by the recommendations of the Science Based Targets Initiative (SBTi). To this end, LEONI is, among other things, expanding use of renewable energy at all its facilities and taking action to improve energy efficiency. LEONI also intends to increasingly offset unavoidable emissions with the goal of attaining LEONI’s climate neutrality (scope 1 to 3) by 2045, and as early as 2035 in terms of direct energy consumption.

Up to 80% use of renewable energies by 2025.

2040
2040

100% climate neutrality in scopes 1 and 2 between 2035 and 2040.

In tandem with reducing emissions, unavoidable emissions will be offset with certificates.

2050

90% CO2-reduction of our emissions in scopes 1 to 3.

By 2025, we will have reduce our scopes 1 and 2 emissions by 17% and our scope 3 emissions by 10%.

The Greenhouse Gas Protocol

The Greenhouse Gas Protocol serves as the internationally recognised standard for balancing emissions. LEONI is currently focusing on measures to reduce scope 1 and 2 emissions, which are caused mainly by purchased and consumed energy. Most of the emissions that LEONI causes for its own business operations have their origin in the upstream and downstream value chain (scope 3). LEONI intends, in this respect, to expand its own emissions balancing in certain categories and to develop reduction measures.

How does the Greenhouse Gas Protocol work?

LEONI's science-based reduction targets (baseline year 2021)

In 2022, LEONI computed a science-based reduction pathway that shows the reduction of emissions that LEONI must achieve to lower its scope 1 and 2 emissions and meet the 1.5 degree Celsius target. We have consequently set ourselves the goal of a 38% scope 1 and 2 reduction by 2030 and of 90% saving for the year 2050, in each case compared to the 2021 baseline year. Through continuous reduction measures, LEONI is planning for 90% less emissions by 2050. In order for LEONI to become climate neutral (scope 1 and 2) between 2035 and 2040, from 2035 onwards emissions that cannot be saved will be offset by certificates. To embark on this path as quickly as possible, LEONI has furthermore set itself the target of saving 17% of emissions by 2025.

Reduction of LEONI's scope 1 and 2 emissions

Wiring systems for low-emissions mobility

Mobility of the future will be sustainable and decarbonised. We will play our part in making this happen. We will lower greenhouse gas emissions by continually developing our wiring systems. Particularly reducing the weight of our wiring systems will save fuel and thus emissions on journeys. In collaboration with our customers, we are also striving to broaden our product portfolio to include sustainable product solutions and production processes, and thereby also to contribute to e-mobility, for example.

Conversion to renewable energies

The switch to sustainable electricity procurement at LEONI is in full swing. To further expand the sustainable supply of electricity to our facilities, we intend in future to rely not only on external suppliers but also increasingly on our own power plants. Solar roofs and photovoltaic systems play a particularly important role here, and we are successively expanding them.

In 2022, LEONI carried out, among others, the following measures in the area of renewable energy and energy efficiency:

  • switch of all sites in Serbia to power supply from renewable energy,
  • switch of all German sites of Automotive Cable Solutions (ACS) Division to power supply from renewable energy,
  • installation of photovoltaic systems at the sites of the Wiring Systems Division (WSD) in Berrechid and Bouznika, Morocco, and in Hermosillo and Mérida, Mexico,
  • a feasibility study for the installation of photovoltaic systems at the ACS sites and
  • switch to LED lighting at the site in Lacanche, France.

Transparent and climate-friendly value creation

Looking forward, we intend to decarbonise our entire value chain – including our logistics and the operations of our suppliers. Only together can we achieve our vision of climate-friendly and resource-efficient mobility that is accessible to all. We have already set ecological standards with our Code of Conduct for Business Partners. In addition, we are currently working on making the carbon footprint of our purchased materials more transparent and thus being able to incorporate further sustainability criteria into our procurement.

Environmentally friendly transport

At LEONI, emissions are also caused by means of transport. Materials and products need to be transported between LEONI’s sites and its customers and suppliers, in some cases across long distances. At present, there is not yet any overarching management approach designed to reduce the accompanying greenhouse gas emissions. LEONI is, however, taking individual measures that can help reduce the carbon intensity of transports associated with its business activities.

Among other things, LEONI is working to optimize logistics flows by combining transport and full utilization of means of transport, as well as by purchasing from regional suppliers. Transport by rail is preferred provided that connections are sufficiently frequent, fast and economical. In addition, LEONI uses returnable load carriers that circulate between its own locations and customer locations over a period of several years.
The corresponding small-load carriers are mostly made of plastic while bulk carriers are made from wood as a renewable resource.

In 2022, LEONI implemented various measures in order to ensure environmentally friendly transport, including the following:

  • Localizing production at the sites of the Automotive Cable Solutions (ACS) Division in China and Mexico and
  • switching inbound transports from China to transport by rail.
