*Emissions year 2018

The top 25 flyers represent...

0%
of business travel
emissions
of companies
in the ranking

...and if they set -50% reduction targets, this would achieve

0%
of the reduction
needed
to keep aviation
within 1.5°

A small group of well-known companies have a bigger share of emissions than the rest of the companies in the ranking. The 25 biggest flyers without a target collectively account for 6.9MtCO2 of air travel emissions in 2019, or 36% of emissions from top companies in our ranking. 

If the top 25 biggest flyers in our ranking set -50% targets for their business travel emissions by 2025, it would achieve 31% of the reduction across all companies. However, too many of these big emitters don’t have specific business travel reduction targets. The Travel Smart campaign calls upon them to set emissions reduction targets, and imitate best practices of their peers who have done so.
