Schott is preparing to face up to the challenges of climate change more than ever before by becoming climate neutral by 2030 and actively contribute to climate protection.
Dr. Frank Heinricht, Chairman of the Board of Management of Schott believes there is no other company in the specialty glass industry that has ever set itself such an ambitious goal.
The “Zero Carbon” project is said to be an integral part of the new Schott group strategy.
As a specialty glass manufacturer, the company operates in an energy-intensive industrial sector.
Specialty glasses and glass-ceramics are melted in large melting tanks at temperatures of up to 1,700 degrees Celsius.
“We see three steps in our commitment to climate protection: first, we want to avoid as many climate-damaging emissions as possible, significantly reduce unavoidable emissions in the next step and, if nothing else is possible, finally compensate for the remaining emissions,” said Dr. Heinricht.
The action plan on achieving climate neutrality at Schott contains four fields of action:
* Improvement of energy efficiency
* Switching to green electricity
* Technological change
* Compensation for technologically unavoidable emissions
Energy efficiency as a permanent task
The introduction of oxy-fuel melting technology and the increasing use of electricity to heat the melting tanks since the 1990s has already made it possible to reduce specific energy consumption by more than 30%.
As part of the company’s proven energy management system, its experts are working intensively to identify and exploit further savings potential.
Switching to green electricity by 2021
Schott will be relying solely on green electricity in the future.
The company intends to cover 100% of its electricity needs with renewable energy sources such as hydroelectric power, wind power, solar energy and biomass by 2021.
New technologies with a focus on hydrogen
In the long term, the company intends to completely dispense with the use of fossil fuels, as far as this is technologically feasible.
“This transformation process will take time and require high development and investment costs, however,” said Dr. Heinricht.
The company views hydrogen technology as a promising solution.
In addition, researchers and melting technologists are assessing the feasibility of yet other technological approaches.
“We believe that as an innovation driver in our industry we can provide important impulses in this area in the coming years and decades,” Dr. Heinricht added.
Compensation for technologically unavoidable emissions
Until CO2-free solutions for heating large glass melting tanks become available, Schott intends to compensate for technologically unavoidable emissions by investing in climate protection projects.
The group is currently creating a compensation portfolio that meets high standards for the sustainability of the projects.
These could include reforestation projects in various countries that are certified according to strict standards, for example.
To calculate its climate-relevant emissions, Schott considers the emission of all greenhouse gases.
The company currently includes emissions from its own production (Scope 1 of the Greenhouse Gas Protocol) and from energy purchased (Scope 2) in the calculation.
In Scope 3, Schott also takes business trips and employee commuting into account.
In the medium term, the other Scope 3 emissions are then to be included, which also consider emissions in the supply chain.
In order to establish comparability with regard to their climate impact, greenhouse gas emissions are expressed in CO2 equivalents (CO2e).
