It also highlights sustainable travel alternatives, such as rail for certain routes or green taxi services in its travel tools and systems, and through internal awareness campaigns.McKinsey is privately held, but Fortune estimates its annual revenue at $10 billion. The company reported it has about 30,000 employees working in 130 cities globally.
