By 2050, Earth's population will top 9 billion—here’s what we need to do now

A Conversation with United Technologies CEO Gregory Hayes

“Sustainability is not an option for our business going forward. It's an imperative."​​

Our world is growing at an incredible pace. 

By 2050, the world’s population will exceed 9 billion people. More than two-thirds of that population will live in cities. The middle class will blossom from 25 percent today to nearly 60 percent by 2030. 

So how should companies respond to these megatrends? 

According to UTC CEO Greg Hayes, establishing a commitment to sustainability is at the top of the list. 

"The necessity of sustainability is never more apparent than when you look at some of these demographic trends," Hayes explained during  a conversation on sustainability hosted by The Atlantic"People want to stay connected. Doing it in a sustainable method is the only way you're going to be successful." 

Hayes proceeded to discuss how UTC technological innovations — in buildings, food delivery and air travel — have the potential to meet the need for more sustainable products and behaviors around the world. Hayes also highlighted the company's decades-long commitment to sustainability as a core driver of long-term success. 

"As I think about United Technologies, we're a big company," said Hayes. "But the fact is that the whole future of our company is going to be based on two things: one is innovation and the other is sustainability."
