Tracking and reducing our emissions

Our approach

Man-made greenhouse gases (GHG) are a major contributing factor towards global warming, a key challenge of the 21st century. The main source of Jungbunzlauer’s GHG emissions is our product manufacturing process. Our production process requires water and energy, which generates direct (scope 1) and indirect (scope 2) emissions. For our corporate carbon footprint (CCF) we consider the scope 1 and scope 2 emissions of the whole Jungbunzlauer Group, scope 3 emissions are not included in our CCF, since this has no direct influence on our production.

In addition, we regularly assess the individual product carbon footprints (PCFs) of our seven major product groups in order to gain an in-depth understanding of the specific emissions related to each product. Our PCFs consider all emissions within the boundaries from cradle-to-gate. This means, that scope 1 and 2 emissions as well as upstream scope 3 emissions, which occur during the life of a product until it reaches our factory gate, are included.

All of our production facilities have implemented an Environmental Management System (EMS) based on the Plan-Do-Check-Act principles. Following a risk assessment, several Significant Environmental Aspects (SEAs) concerning environmental performance with respect to emissions, energy use, waste generation and recycling are defined. The SEAs are then used to assess and track changes in environmental outputs (e.g. GHG emissions).

Coordination of emission data collection as well as reduction measures is done by our Group Sustainability Manager Operations. Additionally there is a Health, Safety and Environmental Manager in every plant.

Our ambition

We aim to reduce our GHG emissions significantly and to become carbon neutral by 2050. As a first target Jungbunzlauer has made a commitment to reduce its CCF emission intensity (mt CO2e/mt final product incl. by-products) by 10% between 2017 and 2025 (from 2017 levels).

In order to keep track of our emissions and our efforts to reduce GHG emissions, and to determine, evaluate and communicate the carbon footprint of our products, we committed ourselves to performing a regular assessment of our scope 1 and 2 GHG emissionsb. We calculate our CCF on an annual basis (since 2013).

We reached a reduction of 8% in emission intensity between 2013 and 2020. However our CCF intensity rose by 15% between 2017 and 2020.

Since 2013 we assess our PCFs every three years, in order to monitor the emissions of our individual products more accurately. The latest PCF assessment was done for the reporting year 2020.

All our carbon footprint calculations are performed in accordance with ISO standard 14040/44, based on secondary data from ecoinvent V3.6 and externally verified by myclimate, an independent non-profit organisation with extensive expertise in lifecycle assessments.

Emission reduction projects implemented in 2020 in our production sites

  • Only renewable energy is purchased in Ladenburg, Germany

  • Energy savings by optimisation of energy management in Port Colborne, Canada

  • Additional insulation of buildings and plant equipment lead to energy savings

  • Installation of more energy efficient lighting

  • Optimisation and additional heat recoveries in production

  • Installation of additional frequency converters for improved use of power

  • Savings in transportation through logistic optimisations

Key measures and evaluation

Our investments in numerous energy-saving programmes have resulted in a substantial reduction in energy consumption per unit of production. We also work continuously on minimising greenhouse gases emitted by our factories.

Corporate Carbon Footprint Continued reduction of our CCF emission reduction from 2017 to 2025 Reduction of CCF (mt CO2e/mt final product incl. by-products) by 8% between 2013 and 2020 as a result of company-wide energy saving programmes, water-saving projects and improved production processes at our plants
Product Carbon Footprint Continued reduction in all PCFs For most products a reduction of PCF was achieved between 2017 and 2020 PCFs for CITROFOL® and special salts, which have been assessed for a group of products in the past, have now been split further into individual products for more accuracy

Definition of Carbon Footprint

  • The total set of greenhouse gas (GHG) emissions caused by an organisation, event or product
  • Measured by undertaking a GHG emission assessment
  • Expressed in terms of the amount of CO2e
    (CO2 and its equivalent of other GHGs)

Corporate Carbon Footprint (CCF)

The slight rise in emission intensity from 2017 to 2018 can be attributed to a change in production mix with more energy-intensive products. The higher CCF intensity recorded for 2020 can be explained by a higher emission factor for gas (scope 1) and electricity (scope 2) as well as a new methodology in regard to wastewater treatment, leading to significantly higher emissions.

It is not satisfactory that we could not reduce our carbon footprint. However the developments have to be seen in light of an extraordinary year. The COVID-19 pandemic lead to an excessive demand of our products. We thus increased manufacturing to the highest amount possible, at the expanse of running our plants in the most efficient way, sacrificing the optimisation of our carbon footprint. Specifically for xanthan gum production we had to use back-up equipment which is not up to our high efficiency standards of today, thus leading to higher emissions. We will reverse this trend in the coming years.

Development of CCF intensity for Jungbunzlauer global. In accordance with the GHG Protocol, this includes all direct GHG emissions stemming from sources that are owned or controlled by Jungbunzlauer (scope 1) and indirect GHG emissions generated by purchased electricity consumed by Jungbunzlauer (scope 2). Scope 3 emissions are not included in our CCF calculation. Emissions are reported in CO2 equivalents, which include CO2, CH4, N2O, HFC-23, HFC-134a and SF6.

Product Carbon Footprint (PCF)

In 2013, we evaluated the PCF for all our major products for the first time. Compared to this baseline, we have reduced the PCF per tonne of final product in almost all of our product categories.

Further reductions were achieved in most product categories between 2017 and 2020. For example for citric acid and lactic acid the PCF was reduced by 25% between 2013 and 2020.

For more accuracy, in 2020, PCFs for our range of CITROFOL® esters and our different special salts, were assessed as individual products, not as a group of products anymore. Since the values can thus not be directly compared between 2013 and 2020, these PCFs are not included in above graph. In our 2020 PCFs, more precise data on scope 3 for wastewater was evaluated, resulting in slightly higher PCFs.

By implementing new technologies and measures, we still strive to further reduce our emissions.

Going forward, one of the key challenges will be to grow our capacity in many product areas and extend our offering while at the same time further reducing future emissions per tonne of product manufactured. To tackle this challenge Jungbunzlauer will continue to invest in state-of-the-art process technology, innovate for safer products and processes that conserve resources and provide enhanced value, seek opportunities to evaluate new environmental control technologies, and encourage employees to be active in protecting our environment.

The next PCF assessment is scheduled for 2023. We will continue to evaluate our CCF on a yearly basis.

To underline the importance of our aspiration to further reduce GHG emissions, Jungbunzlauer plans to commit to the Science Based Target initiative (SBTi) in 2021 and set ambitious emission reduction goals in line with the Paris Agreement.
