Our collaborators and validators

Who should use it?

Any organisation that is committed to baselining their Scope 3 emissions and engaging their workforce in the process.
For large businesses (250+ staff) the data our tool captures, is part of your Scope 3 emissions. Legally, you must report Scope 1 and 2 emissions but baselining Scope 3 is strongly recommended. It is also likely to be part of your larger ‘Carbon Reduction plan’, ESG strategy and Science Based Target.
For smaller businesses, the data and insights can be used for tenders, contracts and to share with your stakeholders who may request it. Most government tenders will ask for this information as part of a ‘Carbon Reduction plan’, and qualifying as BCorp, requires demonstration of action.

Why it is important to measure home working emissions?

The transition to remote working has moved carbon emissions produced at the office to the home. Increased home energy costs and increased remote work emissions result from more remote workers. Whether or not remote work is here to stay, it contributes more significantly than ever to many businesses’ carbon footprints.

Your employees still produce home working emissions on your company’s behalf even when they don’t take place at the locations that your business owns.

What causes emissions in a home office?

Simply put, it’s all the technology that your remote workers use to complete their tasks, including computers, monitors, printers, keyboards, lighting, heating, and cooling.

Making environmentally friendly adjustments such as changing to a renewable energy tariff, switching lighting to low energy LEDs bulbs and ensuring devices are turned off fully after use, can help you reduce your carbon footprint at home.

Our hybrid-working tool helps your business and employees calculate their carbon footprint from homeworking and commuting. It is based on validated methodologies using the GHG protocol and EcoAct’s teleworking approach. It takes employees just 5-10 minutes and the data provided is ready for direct reporting to all major bodies.

How often would you use it?

We recommend using our Hybrid working tool at least on an annual basis to give you an up to date baseline, and when you have new employees join the company.

Can I use the data from this for SBTI / Scope 3 carbon reporting?

Yes, it is one of the best ways to capture Scope 3 Category 7, commuting and teleworking.

Our validated hybrid-working survey is based on GHG protocol commuting calculations and EcoAct’s teleworking methodology. It takes 5 minutes for employees to complete and provides data ready for direct to reporting to all major bodies.

Is your process externally validated?

Yes. The Sustainabl Hybrid working tool combines validated methodologies, enhanced logic and a unique user experience to calculate employee commuting and home working carbon emissions. It has been independently reviewed and validated by Positive Planet, a UK based Sustainablility Consultancy. We work with Positive Planet to ensure our calculations are based on best practice and the latest emissions data, they also provide third party assistance in reviewing data that is to be used for Scope 3 reporting.


What to do next?

Contact us to use our tool within your business and establish an accurate baseline of carbon emissions from your remote workforce. You can then decide how to reduce those emissions using several sensible actions.

Case study: Sacla’ UK, Authentic Italian food

Leading food company Sacla’ is working towards BCorp status and sees it as critical to engage their staff on their journey.

They used Sustainabl’s employee emissions tool to baseline their workforce emissions, getting a 100% response rate in the process as well a range of ideas directly from staff that can enhance and their accelerate their progress further.
