Facts instead of mere assumptions – with the toolbox estell we identify your business sustainability performance in an efficient and transparent manner

The future of successful business lies in the supply chain

Climate change, resource scarcity, human rights violations – in times of complex global value chains, the environmental and social hot spots will be found in the supply chain, often far away from corporate headquarters. Awareness of resource risks as well as regulatory and reputational risks in the supply chain is of high relevance for corporate strategy. Due to insufficient information, however, companies are facing major challenges when trying to gain the necessary insights fast, efficiently and reliably.

Using the toolbox estell we identify the resource consumption, environmental impacts and social hot spots of your company as well as your entire supply chain thoroughly. We determine all environmental and social effects, which can be quantified based on international reliable statistics.

Our company has several thousands of suppliers – without estell the analysis of environmental impacts in the supply chain would have been impossible. estell has helped us to get a good scoring in ratings.

estell provides a comprehensive data basis for corporate sustainability performance

The basis of estell is the readily available data from your financial controlling

estell is based on the recognized economic model of multiregional input-output analysis as well as quality-assured data of international environment, resource, and social statistics. estell provides fact-based findings instantly – without collecting enterprise-specific information in a costly and time-consuming process.

Only readily available information from financial controlling is required for the analysis: purchasing data per cost center and cost unit as well as – if applicable – the country of origin. If available, specific sustainability data of locations and suppliers can be considered.

The approach to capture the environmental impacts of the supply chain with monetary information facilitates many analyses and is the key for companies to a comprehensive sustainability management. The approach is methodically sound and is based on facts.

Dimensions of Analysis (optionally combinable):

  • value chain step
  • sustainability impact
  • product group
  • business unit
  • region
  • supplier
  • process (polluter of impact)
  • emissions (polluter of impact)
estell allows a detailed driver analysis of sustainability effects

Estell can identify the countries and economic sectors which drive the environmental and social effects in the upstream supply chain. Moreover, comparison between different product groups, business units or stages within the supply chain provide revealing insights on which aspects of sustainability are particularly relevant for your company.

Thus, companies are able to set their priorities for sustainable development quickly and appropriately. Sustainability in the supply chain can so become immediately a part of the corporate strategy.

Consistent degrees for comparison and effect evaluation

In addition to physical impact figures (e.g. kg CO2 emissions or m3 water consumption) for ecological effects we use the internationally recognized measurement concept of external costs. This way, we are able to relate individual environmental categories (greenhouse gas emissions, air pollutants, water consumption, land use) and compare them in a useful manner. Moreover, environmental effects can be set in ratio to financial figures.

To identify social hotspots we use the standardized measure of social risk hours.

Alternative approaches often do not meet the articulated demands

Generic life cycle assessments

Lack of data availability: Data is not available, not fact-based or inconsistent

Completeness can be hardly guaranteed

Time-consuming and expensive

Specific supplier data

Lack of data availability: Data is not available, not fact-based or inconsistent

Large number of suppliers, therefore very time consuming and expensive

Indirect suppliers (upstream suppliers) are not considered

Expert opinions

Dependency on restricted fields of competence of the surveyed experts

Difficult to apply in complex value chains

Often only qualitative statements

Using estell you can determine sustainability-related risks and opportunities, identify your potential for improvement, set realistic goals and integrate your partners in the supply chain. The results of the analysis can be communicated in a simple and comprehensive way to increase your operational reputation externally.
