To compile all the data for company level reporting, you will need to choose a methodology and build or use an existing carbon footprint calculator or ESG Management Platform. There are free software tools available online to help your company understand and calculate the emissions from its own operations, as well as ESG Management Platforms.
Here is an overview of the criteria to consider before choosing which tool to use:
1/ Reporting standards and methodologies
Depending on your reporting objectives, you may need to choose a specialised tool that allows you to follow standards for regulatory compliance (e.g. Greenhouse Gas (GHG) Protocol) or to integrate your carbon footprint management into a broader sustainability reporting, such as ISO management.
2/ Training and certification
It is important to take the time to be properly trained on the chosen tool. You will need to check what type of training is available.
Please note that:
To take your journey further, it is advisable to have a trained project leader in-house or to be accompanied by specialists.
