{% hint style="info" %}
The CO2e calculation and data model used to determine the VechainThor Blockchain emissions are based on the best available information and methods at this time. However, these methods and information may change in the future due to new research, updated methodologies, or changes to the underlying data. Therefore, the emissions calculations and data for the current period may be subject to revision in the future. We will make reasonable efforts to keep the vechain blockchain emissions data up-to-date and accurate, and we appreciate your understanding as we strive to improve the emissions reporting.
