Free Carbon Calculator

Carbon Calculator

Helps you calculate your company's carbon footprint with a free calculator.

Emission factor database

With the help of a completely open, constantly growing emission factor database, carbon dioxide emissions can be easily calculated - just by entering your consumption data.

Own emission factors

You can also use your own emission factors, and you can get help from, for example, your own electricity company.

No paywall

Later, the open emission factor database will be expanded with the help of artificial intelligence. In our opinion, emission factor data do not belong behind paywalls, but to accelerate the sustainable change!

Effortless reporting

CO2 emissions

As a result of the carbon calculator, users get the reports of the carbon footprint of their own operations, which customers demand to report and which will soon affect the availability and terms of financing.

Sustainability reporting

When users have started sustainability reporting by measuring the carbon footprint of their own operations, they can define the current status of other sustainability practices using the UN's Global Compact framework from January 2023.

Customer reporting

It is easy to report the results of the carbon calculator to the customer using the platform or download them in spreadsheet format for your own reporting template.

Embed on your website

Users can also attach the report generated by the platform to their own website in visual PDF format.

Data from value chains

Data collection automation

When companies are empowered to produce data on the sustainability and responsibility of their own operations, the Data Chain tool enables the automation of new data collection, for example from supply chains.

Regulations for data collection

With the Data Chain tool, the user creates rules and sequences for collecting new data. Our experts will be happy to help you create the regulations that best suit you.

Significant cost savings

Large companies can save hundreds of thousands of euros per year by improving the collection of mandatory data from their own supply chains.

Complimentary solution

We compliment existing systems by providing an application programming interface (API) from which new data can be easily retrieved.

Risks and opportunities

Data collection progress

Map supply chains by sending an invitation to direct suppliers, who forward the mapping invitation. Follow in real time how your own supply chains are formed. Data collection requests can be sent to entire chains and data can be collected and analyzed in your own situation room.


The views of the dynamic and visual situation room help to analyze e.g. risks related to supply chains, such as incomplete data and water and climate risks.


All supply chains can be viewed by filtering according to usage needs so that the information can be managed in aggregates. The features focus on identifying and prioritizing development needs for the sustainability of supply chains.

These things can be very complex and extensive, but AskKauko has set out to make tools that help entrepreneurs who are unfamiliar with the topics to quickly get started from almost "zero level".
Arto Vidgren, Sustainability coach, Tuottteistajatalo Coaching Ky
"The process that seemed difficult turned out to be easy thanks to experts and an agile and easy-to-use platform. The process was significantly less labor-intensive than we expected, although some information had to be clarified a little more. In the future, it will be easier to visualize our progress thanks to the ImpactOS platform, and once the process has gone through and the platform is in use, updating and monitoring data in the future will not require as much work. Thus, we can focus resources on business development and improving sustainability."
