Guide to the Microsoft Excel Add-In
Utilize Climatiq-specific functions in Microsoft Excel to seamlessly convert your business activity data into carbon estimates across various activities, such as travel, energy usage, and fuel consumption.
Overview
Climatiq’s Microsoft Excel Add-In transforms your spreadsheets into a powerful environmental impact assessment tool. No coding is required, allowing you to quickly create proofs of concept and collaborate with your team for feedback before fully integrating Climatiq’s API or developing advanced features. The Add-In lets you visualize results directly in Excel and share detailed emission reports, streamlining approval for sustainability projects with reliable data.
Since this tool provides a simplified version of our API endpoints, we recommend reviewing our documentation or using the guided Postman collection if you are interested in accessing the full capabilities of the API.
Getting Started
Access to Climatiq's API generally requires a commercial subscription. However, for this Add-In, we offer a free starter plan that includes up to 500 emission estimations per month, granting access to all advanced emission calculations, e.g. the emission estimations for travel, freight, energy and the Autopilot. Without this plan or a commercial subscription, functionality will be limited to basic estimations, i.e. General Estimates and General Search. Upon installing the Add-In via Microsoft AppSource, you will automatically be enrolled in this plan. Alternatively, you can sign up for the starter plan here (opens in a new tab). If you anticipate commercial usage or usage beyond the free starter plan limit, please reach out to our team (opens in a new tab).
If you prefer a video introduction, here is a 2 minute quickstart guide:
Installation of the Add-In
You can install the Add-In from Microsoft AppSource (opens in a new tab). Once installed, it will appear under the "Add-In" menu in the Excel toolbar.
Setting the API key
Next, you'll need to set an API key for the Add-In to call Climatiq's API. Follow these steps to obtain your API key. Once you have it, set the key by executing the following function:
The API key will be stored permanently for this specific file and other users using this file will also be able to make use of the functions. This also means that you will have to set the key once for every new Excel file in which you'd want to use this integration. You can always overwrite the stored API key by calling the above mentioned function again.
Explore the demo
You can familiarize yourself with the Add-In be exploring the demo file we have prepared. It provides different examples on inputs for all available formulas. You can download the demo here.
Support and Feedback
In case of questions, please reach out to the Climatiq team via the website chat or the support form (opens in a new tab). We also appreciate any feedback being shared through these channels.
General Concepts and Notices
To get the most out of the Add-In, it's important to familiarize yourself with the following concepts.
"ShowDetails" Flag
For all Estimation and Autopilot functions, you can choose whether to receive additional calculation details or just the estimated CO2e value in the response. Refer to the documentation for each function to see which details are available. The additional details will be stored in the cells following the one containing the function.
Optional Parameters
Typically not all parameters are required when using the functions. The documentation indicates which ones are required and which ones are optional. In case no value should be used for the optional parameters, please simply leave them empty, e.g. Climatiq.Calculate_Travel_Air(start, end, flightclass) as Climatiq.Calculate_Travel_Air("BER", "JFK").
Error Handling
In addition to common errors, functions will return specific errors from the Climatiq API if an input is incorrect, or if the provided API key is invalid, or a suitable emission factor cannot be found by the API.
API Consumption and Recalculation of Results
By default, Excel will re-calculate the results for functions everytime an input changes or the file is reloaded. Every re-calculation will also count as a call to the Climatiq API. To avoid overconsumption of your subscribed API calls, it is recommended to copy-paste the values of the calculations into the cells as soon as the calculations are complete. To do this, you should select the cells with the calculation results, copy them and paste them back into these cells via Edit > Paste Special > Values only. You can disable the automatic recalculations under the settings for "Calculation options" in the "Formula" ribbon.
Documentation within the Add-In
To see an overview of the available functions in a sidebar within Excel, simply open the documentation by clicking the Climatiq icon in the main menu bar.
Access to all functionalities
By default, when signing up for the Climatiq API, the initial access only covers the usage of the general estimation and search capabilities. For any advanced calculations, e.g. emission estimations for air travel, additional access needs to be granted for your API key. Otherwise the following error will be shown when trying to make use of an advanced features, that has not yet been enabled for your account:
Your authentication is valid, but you do not have access to this feature.
To enable these advanced features, you can sign up to a free starter plan, which covers up to 500 emission estimations monthly across advanced emission calculations. You can sign up for this plan here (opens in a new tab). And in case you are interested in large-scale usage of the integration, please reach out to our team (opens in a new tab).

Autopilot
Autopilot is an AI-powered calculation endpoint designed to automate spend- and activity-based emission estimates. It uses a proprietary natural language processing (NLP) model paired with Climatiq’s scientific expertise to streamline complex emission calculations, making carbon insights accessible to non-experts.
Autopilot significantly reduces the time and manual effort spent identifying the appropriate emission factors and mapping activity data. Capable of ingesting any taxonomy and unstructured data, this feature matches raw text content to the correct emission factors and delivers accurate and compliant emission estimates.
Leveraging a built-in expert review mechanism and machine learning, Autopilot's matching algorithm consistently refines its precision. This is achieved through active feedback and continuous improvement of the underlying NLP model.
