Twice as many CEOs in 2014 see sustainability as their top priority than two years ago.

A new survey by McKinsey found 13% of CEOs saw it as their most important priority as opposed to 5% in 2012.

The online survey run in February 2014 polled 3,344 executives across different regions, industries and company sizes.

Executives believe sustainability is becoming a more strategic and integral part of their businesses, the report suggested.

It pointed to past surveys where respondents most often cited cost cutting or reputation management for acting sustainability.

Now 43%, the largest share, said their companies seek to align sustainability with their overall business goals, mission, or values, up from 30% who said so in 2012.
