How do you assess sustainability?

Startups can assess their sustainability by first defining clear sustainability goals that fit their business model. Measurable indicators are essential to track progress. It’s important to view sustainability as a process that is regularly reviewed and adjusted.

The following seven free tools can assist you in assessing your sustainability. The tools are suitable depending on the phase and context of your startup. With the following guide, we outline the best application for your needs. Which tool is best for your sustainability assessment depends, among other things, on whether you are in the pre-founding stage or if your company is already active.


How do you evaluate sustainability?

Startups can effectively assess their sustainability by initially establishing well-defined goals that align with their business model. Employing measurable indicators is important to monitor and measure progress. It’s vital to perceive sustainability as an ongoing process that undergoes regular review and adjustments.

To support this evaluation, we recommend seven free tools tailored to different startup phases and contexts. Our guide outlines the optimal application of each tool based on your specific needs, considering factors such as whether you are in the pre-founding stage or if your company is already operational.

Pre-founding phase

-> How do you assess the potential impact of your startup with a business idea and a rough plan? 

1. Stanford Impact Compass

Duration: about 15 minutes

With the Stanford Impact Compass, you can assess the impact potential of your startup. Even before founding, you can establish a clear mission, which is crucial for attracting investors and customers. The Stanford Impact Compass offers a quick, semi-quantitative query with six categories:

  • Value for society 
  • Maturity 
  • Effectiveness 
  • Scalability 
  • Business model 
  • Impact in the area of environment, social and corporate governance 

The Stanford Impact Compass website offers a recorded webinar and a whitepaper including examples to help fill it out. However, the tool is just a start: the categories and the assessment grid are rather generic.

2. Sustainable Business Canvas

The Sustainable Business Canvas is content and structurally based on the Business Model Canvas and allows qualitative text input. It offers a clear template that is also suitable for presenting the sustainability aspect of your business model in ten points:

  • Vision and mission
  • Key partnerships
  • Key activities
  • Key resources
  • Value proposition
  • Customers
  • Competitors
  • Other stakeholders
  • Cost structure
  • Revenue model

Although the tool lacks a feedback system, it’s ideal for iterative engagement with your business model. Specific guiding questions help you fill out the template considering sustainability criteria. Numerous tips, examples, and valuable accompanying materials make it easier to fill out the Sustainable Business Canvas.

3. Application tool of the DIN SPEC 90051-1

Duration: 1 hour

The practice tool of the DIN SPEC 90051-1 is a guideline for assessing the sustainability of startups according to European standards. The sustainability assessment consists entirely of qualitative multiple-choice questions and is suitable for both a rapid preliminary assessment or more thorough due diligence. Like the Sustainable Business Canvas, this tool is also content based on the Business Model Canvas. Structurally, it differentiates between enabler and result criteria. Enablers are factors that enable startups to act sustainably. Results are the effects that already emanate from a startup:

Enabler criteria

  • Vision and strategy
  • Team
  • Processes
  • Partnership and resources
  • Product, service, and market position

Result criteria

  • Effects on target groups
  • Effects on other stakeholders
  • Effects on the environment, economy, and society

Although the tool lacks a feedback system, it’s ideal for iterative engagement with your business model. Specific examination questions support a conscientious answering of the survey. Dealing with the sustainability assessment can be resource-intensive but goes deeper.

4. Sustainability Management Checklist

Duration: 45 min

The Sustainability Management Checklist is already suitable before you have founded your startup and just want to get a comprehensive overview of potential measures in sustainability management. It’s also useful in the founding phase, when you want to iteratively deal with where you stand in terms of sustainability priorities and goals.

The comprehensive Excel checklist allows the assessment of measures in four sustainability categories:

  • Corporate governance
  • Environment
  • Social
  • Supply chain

You assess the current state of your sustainability management from “not met” to “met.” This tool primarily targets product-oriented startups with its supply chain focus, but the checklist works for all startups. Irrelevant questions can be marked and excluded from the overall analysis, where the optimization potential in the individual categories is shown. However, the tool does not offer action instructions. Startups must engage independently and iteratively with the results and interpret them.

  • Strategy/Innovation
  • People/Skills
  • Operation
  • Collaboration with stakeholders
  • Products/Materials
  • Services
  • Infrastructure/Property/Equipment

The tool scores each category without offering specific action steps, requiring additional analysis to interpret the results.

  • Environment

  • Corporate governance 

You evaluate the external impact in line with the 17 UN Sustainable Development Goals. The tool supports you in goal setting, based on the completed survey on operational sustainability. To access the tool, you must create a free account.

  • Corporate governance 
  • Employees 
  • Society 
  • Environment 
  • Customers

This case study was conducted in collaboration with Impact Hub Basel and FHNW, enabled by Innosuisse. We engaged startups at various stages of development to test these tools in a workshop setting. Our collective goal is to create and introduce a program that equips startups with the means to build sustainable business models from the outset.

If you’re aware of any tools or services that can aid startups in embarking on their sustainability journey and believe they should be included in our list, we welcome your suggestions. Please feel free to share information about these resources with us.
