GRI 305: Emissions

Management approach

The conservation of natural resources and climate change are two of the biggest challenges now facing the global community. Interseroh wishes to play its part in limiting global warming. The company achieves this by providing products and services to customers on the one hand, and by continuously reducing its own environmental footprint on the other. This objective was set out as part of the sustainability strategy: greenhouse gas emissions are to be reduced continuously, site-specific optimisation work is to be carried out and the corporate carbon footprint (CCF) is to be calculated.

In 2017, the company used this CCF to formulate a climate strategy and define goals:

  • By 2025, Interseroh will reduce its site emissions (Scope 1 and 2) by 50 percent compared with the 2015 baseline.
  • As regards logistics, Interseroh is continuously looking for areas of potential optimisation and working towards its goal of reducing logistics-related emissions.
  • In the future, Interseroh wishes to use its services to make an even greater contribution to the circular economy and reduce emissions. In 2018, Interseroh set itself a quantifiable goal for this area: The company aims to save at least 5.5 million tonnes of raw materials and 800,000 tonnes of greenhouse gases annually with its services.

305-1: Direct (Scope 1) GHG emissions

In 2018, Interseroh’s site-based greenhouse gas (GHG) emissions, including emissions from business travel, totalled 29,449 tonnes of CO2 equivalent (CO2-e), and therefore a year-on-year increase of 900 tonnes. This represents an increase of approximately 3.0 percent, which is due mainly to the expansion of the business.

1 CO2-e emissions are calculated on the basis of the Greenhouse Gas Protocol specifications. Scope 1 and 2 are based on data from account statements and meter readings using the VDA 2014 emission factors. Logistics emissions were calculated for the first time using the Global Logistics Emissions Council (GLEC) framework. The emission factors used for logistics emissions were those set out in the DSLV 2013 guidelines. A number of methods were used to calculate other Scope 3 emissions. These include in particular the expenditure-based method and the use of emission factors from the studies of Interseroh carried out by the Fraunhofer Institute.

3 To enable comparability over several years, only the emissions from business travel are reported in this table in Scope 3.

Corporate Carbon Footprint

In 2017, Interseroh once again provided a full calculation of its corporate carbon footprint. A total of 115,751 tonnes of CO2-e were generated by Interseroh’s activities in 2017. The large part of these emissions stemmed from the business model of contracting work to logistics services providers. Around 69 percent of the emissions reported in Scope 3 – amounting to 60,386 tonnes of CO2-e – can be attributed to transportation services. 

Compared to 2015, emissions have therefore risen by 11,743 tonnes of CO2-e. This is due both to the expansion of the business (largely as a result of the Dual System Interseroh) and to the expansion of our database, particularly within the facility operation and at our international sites. In order to further improve data quality, Interseroh introduced a standardised in-house process that was able to replace the assumptions made in Scope 3 with data and thereby enhance the accuracy of our calculations. 

Interseroh applies the results to make informed business decisions. The company aims to cut emissions when placing logistics orders, for example. One option here is to offer incentives to optimise tour planning. The data and insights gained are also being used to manage the company's business units.

305-4: GHG emissions intensity

In 2018, Interseroh's total CO2-e emissions (direct and indirect site emissions plus emissions from business travel, see overall presentation under GRI 305-1: Direct (Scope 1)) GHG emissions amounted to 29,449  tonnes. The intensity of GHG emissions in relation to revenue amounted to 39.8 tonnes per million euros. The intensity has therefore been substantially reduced from the previous year's figure of 55.4 tonnes per million euros revenue.

  2016 2017 2018
Total greenhouse gas emissions (in tonnes of CO2-e) 30,312 28,581 29,449
Intensity of GHG emissions (in tonnes of CO2-e per 1 million euros or revenue) 61.6 55.4 39.8

305-5: Reduction of GHG emissions

In 2018, Interseroh’s site-based GHG emissions, including emissions from business travel, totalled 29,449 tonnes of CO2-e), and therefore a year-on-year increase of 900 tonnes. This is an increase of 3.0 percent.

The low figure for the previous year is mainly attributable to the Eisenhüttenstadt site, where alteration work required the plant to be shut down for an extended period in 2017. As a result, electricity consumption at the site was approximately 5.1 MWh lower than in 2016. Consumption rose by 2.5 MWh when normal operation resumed in the following year, 2018.

Compared with the 2015 reference year (31,460 tonnes of CO2-e), Interseroh reduced its emissions by 6.4 percent.

To reduce emissions still further, Interseroh converted its Cologne site and its sorting plant in Walldürn to green electricity at the beginning of 2019.
