Environmental Tools (E-tools)

ICAO develops and maintains many Environmental tools that are made available to States and the general public. These tools support the development of State Action Plans, the implementation of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) and support initiatives to reduce aviation carbon footprint. 





ICAO Carbon Emissions Calculator

ICAO has developed a methodology to calculate the carbon dioxide emissions from air travel for use in offset programmes.

ICAO Green Meetings Calculator

The ICAO Green Meetings Calculator (IGMC) is a tool designed to support decision-making in reducing the carbon emissions from air travel to attend meetings.
 
The software generates an optimal location for a meeting in terms of CO2 emissions, taking into consideration the city of origin and the number of participants, as well as other parameters. While many factors may affect the decision for where a meeting should be held, the calculator helps facilitate the planning process.

​ICAO Fuel Savings Estimation Tool

Operational measures are one of the instruments available to States to improve fuel efficiency and reduce CO2 emissions. The ICAO Fuel Savings Estimation Tool (IFSET) has been developed by the Secretariat with support from States and international organizations to assist the States to estimate fuel savings in a manner consistent with the models approved by CAEP and aligned with the Global Air Navigation Plan.

The ICAO Fuel Savings Estimation Tool (IFSET) is not intended to replace the use of detailed measurement or modelling of fuel savings, where those capabilities exist.  Rather, it is provided to assist those States without such facilities to estimate the benefits from operational improvements in a harmonized way.
 
Access the application here: ICAO Fuel Savings Estimation Tool
 
User Guide :
  • Download the IFSET Ver 2.1 User Guide
  • Please note that all the information saved in this web tool can be seen by the public. Therefore you should delete the event when you have finished using the tool.


Environmental Benefits Tool (EBT)

The EBT is a tool developed for supporting States in the development of their State Action Plan.

This tool allows easily generating a baseline scenario, estimating the impact of mitigation measures and finally generating expected results.

 

Please contact us (officeenv@icao.int) if your State is interested in using the EBT.




​Marginal Abatement Cost Curve

This tool offers the possibility to States to identify and rank up to 20 mitigation measures in order to facilitate decision-making. The tool includes a user-friendly interface and is fully customizable to fit the State's situation.


Please contact us (officeenv@icao.int) if your State is interested in using the Marginal Abatement Cost Curves.


ICAO CORSIA CO2 Estimation and Reporting Tool (CERT)


The ICAO CORSIA CERT is one of the five ICAO CORSIA Implementation Elements and is reflected in the ICAO document entitled "ICAO CORSIA CO2 Estimation and Reporting Tool", referenced in Annex 16, Volume IV.


The ICAO CORSIA CERT supports aeroplane operators in fulfilling their monitoring and reporting requirements in CORSIA by populating the standardized Emissions Monitoring Plan and Emissions Report templates. More details on CERT can be found here.
