Understand – Calculate – Act with Confidence
GreenPassportCarbon.com is a B2B SaaS and service platform for Singapore’s MICE (Meetings, Incentives, Conferences, and Exhibitions) sector and Global Multinational Corporations (MNCs).
Every event creates greenhouse gas emissions — from the electricity used at the venue to how attendees travel, where they stay, and the food they consume.
Green Passport Carbon helps you turn this activity into a practical estimate of your event’s carbon footprint.
Our approach is designed to keep the process straightforward:
You provide information about your event. We apply relevant emission factors to that activity data and calculate the estimated greenhouse gas emissions in tonnes of carbon dioxide equivalent (tCO₂e).
The result gives you a clearer picture of where your event’s emissions come from and provides the basis for the next steps in the Calculate → Retire → Certify process.
The Simple Explanation
Carbon calculations begin with activity data.
Activity data describes what happened during your event.
The boundary determines which activities and emission sources are included in the calculation. Green Passport Carbon focuses on material emission sources that can reasonably be associated with planning, operating and attending an event.
Depending on the information available and the type of event, the calculation may include the following major categories.
Relevant event activity data is entered into the calculator or provided during the assessment process.
Applicable emission factors are assigned to the relevant activities.
Activity data is multiplied by the relevant emission factors to estimate greenhouse gas emissions.
Emissions from the included categories are combined and expressed as the event's estimated carbon footprint in tCO₂e.
Activity Data → Emission Factors → Category Emissions → Total Event Footprint
This calculation creates the foundation for understanding the event’s emissions and determining the appropriate next step.
Where reliable event-specific information is available, it should be used instead of estimates.
Where information is unavailable, reasonable assumptions or recognised proxy data may be applied.
Only activities included within the defined calculation boundary contribute to the reported footprint.
The relevant categories can vary depending on the event format, location, duration and available information.
Provide the information needed to assess your event, including key activity and emissions-related data.
Your event information is reviewed, and the estimated carbon footprint is prepared.
Once the footprint is confirmed, the appropriate carbon solution is prepared and the corresponding carbon credits are arranged for retirement.
After the required carbon action is completed, your Green Passport Carbon certificate is issued.
The online calculator is designed to provide a practical indication of your event’s carbon footprint.
It can help event teams:
A calculator result should not automatically be interpreted as a final verified or certified footprint.
Where certification is required, event information and supporting data may undergo additional review before the final carbon quantity is confirmed.
Understanding the footprint is only the first step.
Green Passport Carbon follows a clear three-stage approach:
Estimate and document the greenhouse gas emissions associated with your event.
Where carbon credits form part of the event’s carbon strategy, an appropriate quantity of eligible credits can be retired against the relevant emissions.
Following the required calculation and retirement process, documentation can be issued to support transparent communication and ESG record-keeping.
