As of this year, the American tech company Apple will also look at earnings in the field of sustainable energy, diversity in the workplace and other social and environmental issues when giving out bonuses to top managers from this year.

This is evident from an application that the company filed with the American stock exchange watchdog Securities and Exchange Commission (SEC) on Wednesday.

The change will take effect this year and is designed to motivate Apple executives "to live up to exceptionally high standards of values-driven leadership, in addition to delivering strong financial results," the Apple document reads.

It is not clear from the document how a director makes progress in achieving the bonus.

The financial targets and the thresholds for management bonuses at Apple will not change, the iPhone manufacturer says.

Whether or not to adhere to Apple's values ​​can be decided to increase or decrease the bonus paid by 10 percent.

“For many years we have been at the forefront of reducing our carbon footprint and aim to one day purchase 100 percent recycled and renewable materials for all our products and packaging,” said Apple.

"We believe that diversity is the driving force behind innovation and the key to our success."
