Aviation sustainability: US ageing fleets under the spotlight

If there was any doubt that environmental stewardship is rapidly gaining traction among investors, look no further than the annual letter from the BlackRock (Investment) CEO declaring that sustainability is taking centre stage in the company's investment approach. The declaration is not surprising; however, it should serve as a wake-up call to business executives worldwide that their respective companies need to have a viable environmental, social and governance (ESG) plan in place in order to attract investment.

The scrutiny of the aviation industry's environment footprint continues to grow, and airlines are touting a range of environmentally responsible practices they have adopted, but arguably it is tough to garner a unified message from the industry.

The letter from BlackRock shows that environmental responsibility will become a core part of business for industries worldwide - sooner rather than later. For its part, Delta Air Lines has pledged to become more vocal in the environmental movement in 2020.
