About The Sustainability Consortium (TSC®)

What is The Sustainability Consortium® or TSC?

The Sustainability Consortium® (TSC®) is an organization of diverse, global participants that work collaboratively to build a scientific foundation that drives innovation to improve consumer product sustainability. We develop transparent methodologies, tools, and strategies to support a new generation of products and supply networks that address environmental, social, and economic imperatives.

When was The Sustainability Consortium formed?

The Sustainability Consortium was founded in 2009.

Is The Sustainability Consortium a US organization and why?

The mission and scope of TSC is global. Two U.S.-based universities (Arizona State University and the University of Arkansas) legally administer TSC, but there are also offices in Europe and China and we have members and partners in every continent.

How is The Sustainability Consortium governed?

TSC is governed by an elected Board of Directors with corporate, civil society, and academic representatives and is managed by a global executive team.

Where does The Sustainability Consortium get its funds?

The Sustainability Consortium is a member-based organization that receives financial and in-kind contributions from our corporate, civil society, and academic members and also from the licensing of our tools and services.

How does The Sustainability Consortium ensure that conflicts of interest are managed?

The Sustainability Consortium uses a multi-stakeholder approach to ensure that no single voice be allowed to dominate and to manage any conflicts of interest. All our work and decisions are shared transparently with our members, who help to monitor all our activities. TSC uses published research as its basis for evidence and conclusions and employs a variety of processes to ensure effective and appropriate stakeholder engagement.

What is The Sustainability Consortium’s relationship to Walmart?

The Sustainability Consortium is an independent organization jointly administered by Arizona State University and University of Arkansas. Walmart, which was one of the founding members of TSC, is one of a number of retail organizations that are corporate members of the organization. Walmart was also elected into one of the corporate seats on the TSC Board.

How do I become a member of The Sustainability Consortium?

What are the benefits of membership in The Sustainability Consortium?

TSC provides opportunities to learn about the issues and opportunities in consumer product sustainability, to network with industry sustainability leaders, and to improve corporate social responsibility. For more information see the TSC website: http://www.sustainabilityconsortium.org/join-tsc/.

Is The Sustainability Consortium providing consulting services?

TSC does not provide a consulting service itself but it offers training and other targeted support to members and other organizations. Many TSC members and partners provide consulting services closely related to the work of TSC.

About TSC Product Sustainability Toolkits

What is a TSC Product Sustainability Toolkit?

A TSC Product Sustainability Toolkit includes 2 documents:

  1. A Category Sustainability Profile, which summarizes the environmental and social issues and opportunities associated with a particular product category (e.g., computers, bananas, or plastic toys) and includes Key Performance Indicators, which can be used to assess progress in addressing materially relevant issues.
  2. A Sustainability Snapshot, which is a one-page summary of the Profile written for non-technical business professionals.

Where can I get access to TSC Product Sustainability Toolkits?

You can access the TSC Product Sustainability Toolkit on the SAP Product Stewardship Network or by becoming a member of TSC. 

How can I download copies of the Category Sustainability Profile (CSP) and Sustainability Snapshot to share with my internal teams?

You can download copies of the Category Sustainability Profile (CSP), which contain Key Performance Indicators (KPIs) and supporting information, as well as the Sustainability Snapshot, within the Product Stewardship Network after accessing the Toolkits on the SAP Product Stewardship Network Store (www.sap.com/buytsctoolkits). Please contact the SAP Product Stewardship Network if you have additional questions at psn-support@sap.com.

Where can I learn more about The Sustainability Consortium and TSC Product Sustainability Toolkits?

You can learn more about The Sustainability Consortium and TSC Product Sustainability Toolkits by visiting our website at www.sustainabilityconsortium.org or contacting TSC helpdesk at TSC@walton.uark.edu to request introductory information.

Is TSC Product Sustainability Toolkit available in languages other than English?

TSC Product Sustainability Toolkits are currently only available in English.

What is a hotspot, and what is the difference between a hotspot, an additional issue, and a stakeholder concern?

Hotspots, additional issues, and stakeholder concerns are activities in a product life cycle that have documented environmental or social impacts supported by different levels of scientific evidence. A hotspot is supported by significant, high-quality, non-conflicting evidence. An additional issue is supported by medium-quality or conflicting evidence. A stakeholder concern reflects low-quality evidence.

What is an improvement opportunity (IO), and what is the difference between improvement opportunities designated among different supply chain stages e.g., Product Attributes, Consumer Engagement, etc?

An improvement opportunity (IO) is a practice that improves a product’s environmental and/or social performance relative to one or more hotspots, additional issues, and/or stakeholder concerns. IOs are embedded among different supply chain stages to clarify who would be the major actors to implement such practices.

What is difference between gaining access to TSC Product Sustainability Toolkits via TSC membership versus purchasing the Toolkits directly from the SAP Product Stewardship Network (PSN)?

The content of the Toolkits are the same whether accessed via the SAP Product Stewardship Network or direct from TSC. TSC members can access and use all Toolkits free of charge from TSC Member Portal.  New versions of Toolkits are typically available on the Member Portal before they are launched on the SAP Product Stewardship Network. Non-TSC members can purchase a license for the Toolkits for $699 on the SAP Product Stewardship Network at www.sap.com/buytsctoolkits. Please contact the SAP Product Stewardship Network if you have additional questions at psn-support@sap.com.

Who will have access to the data that I input into the SAP Product Stewardship Network?

The data you enter into the SAP Product Stewardship Network is only shared with organizations that you explicitly specify and you can change those preferences at any time. TSC research staff are provided with aggregated, anonymized data (i.e., no company-level scores or company names identified, only the distribution of responses) from the SAP Product Stewardship Network.

About the Issues Covered by the TSC Product Sustainability Toolkit

What kind of sustainability issues does a Product Sustainability Toolkit address?

A Product Sustainability Toolkit addresses a wide range of environmental impacts such as pollution, climate change, water quality, and resource depletion as well as social impacts such as worker health and safety, labor issues, and community rights.

Why is a key hotspot in the category missing?

TSC only includes issues and opportunities that are materially significant and actionable, as is defined by the quality and quantity of supporting (or conflicting) scientific evidence. TSC uses a structured research process to identify published research studies and then checks the interpretation of that evidence through a multi-stakeholder review.

How are certifications and ecolabels considered in Key Performance Indicators?

The Consortium does not typically endorse specific certifications or ecolabels, but if their criteria are scientifically founded (i.e., based on studies that are publicly accessible & independently reviewed) and if they were developed in amulti-stakeholder context, then specific criteria can be adopted as improvement opportunities and Key Performance Indicators.

What is the geographic scope of the assessment, and how are differences between global markets and regions being considered?

TSC Toolkits are designed to be applicable globally but we recognize different impacts are more or less important in different markets. The geographic scope of a Product Sustainability Toolkit, either global or regional, is specifically clarified in the beginning section of each product category documents. When data and research are being collected, TSC makes special note of assumptions and limitations concerning geographic applicability and includes experts who have knowledge of geo-specific impacts in the discussion.

What if a Key Performance Indicator is only applicable for certain geographies and only pertains to part of our supply chain?

Even if a KPI only pertains to part of your supply chain, you should still answer the KPI related to the portion that is relevant. Many KPIs also include a “Not applicable” response to handle such situations.

How do TSC Key Performance Indicators map to other sustainability surveys?

TSC Key Performance Indicators (KPI) measure performance at a product category level, which is different from sustainability measurement systems that focus at an organizational, factory, farm, or product level. While TSC has not performed widespread comparison to other systems, the Category Sustainability Profile indicates any such linkages that have been identified.

About Key Performance Indicator (KPI) Questions and Response Options

What if I can answer more than one response option, which one should I answer?

Answer the highest applicable answer, e.g., if both (B) and (C) are applicable, you can choose answer (C); otherwise, you can only choose (B).

Why are there questions about issues that are already regulated or controlled by everyone?

Key Performance Indicators are developed based on research and stakeholder participant input. Issues that may not seem differentiating for one organization or region but may be differentiating in other markets.

How should I answer the question if I can’t find a response option that matches what our organization is doing?

If no response options are applicable, answer response option (A).

What is going to happen with the answers I submit? How are different retailers going to use it?

If you respond to TSC KPIs via the SAP Product Stewardship Network, you have the choice with whom to share your responses. TSC does not have details about specific retail programs. If you share data with a retailer they will have the details of how they intend to use the data.

Does anyone check or verify our responses?

TSC does not verify Key Performance Indicator responses. However, users of the Toolkits may choose to implement their own verification or certification process.

How should I answer a question that asks for a percentage if I only have data for a portion of my global business?

Your calculation should be relative to your entire global business, not just the portion for which you have data. Therefore, the maximum percentage response you could enter would be the percentage of your business for which you have data.

Do questions regarding supply chains apply to my company since our organization is vertically integrated and we don’t have external partners?

Yes, a vertically integrated organization still needs to understand the impacts of the different divisions that interact to create a product. For example, third-party audits for worker health and safety or labor rights would happen at the company-owned facilities the same way they would take place at a contracted manufacturing facility.

How do we know if the initiative we participate in qualifies for a particular response option?

The Related Information associated with the Key Performance Indicator (KPI) question identifies examples of the types of programs or tools that are applicable. The Related Information may be viewed in the Category Sustainability Profile available for download in each Product Sustainability Toolkit. 

Some questions ask for percentages. How do I calculate these?

The Additional Guidance associated with the Key Performance Indicator (KPI) question should provide guidance as to how the percentage should be calculated. The Additional Guidance may be viewed from a link under each KPI question in the questionnaire, or in the KPI document available for download in each Product Sustainability Toolkit. 

Should calculations for product or material mass include the mass of thepackaging?

No. Exclude packaging from any calculations involving the mass of product or material produced or purchased. Separate packaging KPIs are included where relevant.

We collected data from our factories or suppliers within the last twelve months, but the data reported actually reflects an earlier window of time outside of the twelve month window. Can we still answer the KPI legitimately?

Yes, data should have been reported to you within the last twelve month period, but there’s recognition that the data may reflect operations previous to that time period.

No, if a supplier facility is assessed as medium or high risk, it can only be included in the percentage response as a “positive” if corrective action has been taken to reduce the risk to a low level.

Can the quantitative data being collected (e.g., GHG emissions, water use, accident data) be used to compare suppliers’ performance?

No, the Additional Guidance rules for these quantitative KPIs does not have sufficient detail and controls to allow for supplier-to-supplier comparison of the reported outcomes. This is why TSC has recommended scoring these KPIs based on the completeness of data collected rather than the value of the outcome metric itself. However, the quantitative outcome data can be used to compare within a single supplier over time, assuming data is collected in a consistent manner.

I’m not familiar with some of the terms in the Key Performance Indicator. Where can I find those definitions?

Every Category Sustainability Profile has a Definitions list in the Appendix.


When calculating the GHG intensity for transportation in the units suggested, the number is very small. Am I doing it correctly?

Yes, the number is likely to be very small. We will change the choice of units in future versions to correct for this. When responding to this question on SAP Product Stewardship Network, you may find that the number you calculate is too small to be accepted by the response field.  If this is the case, you may enter zero as your response.


When calculating an answer in the units suggested, the correct answer requires more than the 2 decimal points the response field accepts. How do I respond?

You may find that the number you calculate is too small to be accepted by the response field, which allows for two decimal places.  If this is the case, you may round up to 0.01 or down to zero as appropriate.


Is primary data required to answer numerical questions, or can regional averages or samples be used?

The numerical responses are intended for primary data only unless the Additional Guidance states that regional data can be reported in the numerical response.  If no primary data are available and the Additional Guidance does not allow for use of regional data, you must answer response (A) “We are unable to determine at this time.”

When primary data are available, enter the numerical response and the percentage of product or supply that corresponds to the primary data available. You may also use an estimate based on a primary data sample of your product or supply, in which case, you should enter the percentage of product or supply you sampled from the total amount of supply.

If the Additional Guidance states that you may use a regional average, then enter that average in the numerical response and report 0% for the percentage of product or supply.

Since only the percentage of product or supply is being scored at this time then only those KPIs that respond with primary data and the corresponding percentage of product or supply will be scored.  A response of “We are unable to determine at this time.”, or a response with a regional average and a percent supply of 0% (as instructed above) will receive a score of 0 for the KPI.


How do I respond to the % supply of high risk supply with a site-based management program (C2) when our third-party verification determined there is 100% low risk for violating tradition/civil rights in our wood supply (C1)?

The question is designed to give credit to businesses that are conducting both risk assessments and site-based management programs. In the case where a risk assessment indicates 100% low-risk supply (C1), then in C2 you can enter the percent of your supply that is covered by a site-base management program, whether low or high risk.

The Hotspots or Additional Issues in this KPI only refer to sugarcane. Do I answer the KPI for my beet sugar supply as well?

If sugarcane is the only supply chain identified with Hotspots and Additional Issues within a KPI, answer the KPI only for your sugarcane supply and not for your beet sugar supply.

About Research and Stakeholder Engagement in TSC

What is the process for producing a Product Sustainability Toolkit?

First, TSC research staff and stakeholders define the boundaries of the product category and identify published research about impacts and improvement opportunities. The Consortium summarizes the pertinent information into a Category Sustainability Profile using established rules that examine the quality and quantity of evidence about the issue or opportunity. Finally, Key Performance Indicators are developed that link hotspots and improvement opportunities to specific metrics. From there, Sustainability Snapshots are developed by mapping hotspots to business objectives and sustainability issues to create a one-page summary of the Category Sustainability Profile.

How are stakeholders involved in the process of developing the Product Sustainability Toolkits?

The Sustainability Consortium engages corporate, academic, government, and non-governmental organizations as stakeholders. Stakeholders bring expertise and industry insight to the development of the TSC Product Sustainability Toolkit throughout the entire process. In addition to attending workshops, stakeholders submit written feedback and input to the drafts of documents that are created.

Who can participate in the review of TSC Product Sustainability Toolkit?

TSC members and other selected stakeholders provide input to TSC to help identify possible hotspots and improvement opportunities associated with a product category and they review and provide feedback on Category Sustainability Profiles and Key Performance Indicators to help make them accurate and actionable.

How can experts who are not part of TSC membership engage?

TSC researchers and members reach out to external stakeholders when we start work on a new product category, and experts can provide input to the research process..

About TSC Product Sustainability Toolkit Categories

How is it decided what product categories will get a TSC Product Sustainability Toolkit?

TSC chooses the product categories to work on based on their estimated impacts, which is related to their impacts per product and the volume of products sold.

When do revisions of TSC Product Sustainability Toolkits occur?

Each TSC Product Sustainability Toolkit is revised within one or two years of initial development, unless otherwise determined by TSC staff and participants. Subsequent revisions are considered as needed.

When will additional product categories be added to the system?

TSC develops Toolkits for new products every year. A list of completed product categories can be found at the following link: http://www.sustainabilityconsortium.org/product-categories/.

How do I choose between the Plastic Product, Metal Product, or Metal and Plastic Product Sustainability Toolkit?

These categories are used for manufactured goods that do not currently fall under one of the sector-specific categories. If you have metal products in the category that contain more than 2% plastic or plastic products that contain more than 2% metal, then use the Metal and Plastic Product Sustainability Toolkit.
