India-born Google CEO Sundar Pichai has pledged $1 billion in new initiatives to prepare people for the next generation technology jobs.

At an event in Pittsburgh, Pichai said Google will spend the money over the next five years to fund grants to nonprofits globally, CNET reported late on Thursday.

Google will fund organisations working in areas like closing the world's education gap, helping people prepare for the changing nature of work and ensuring that no one is excluded from opportunity.

"We're always asking how we can make sure the opportunities created by new technology are available for everyone, in any city, in any state," Pichai was quoted as saying.

Pichai also announced a second programme under which Google employees will be able to donate one million volunteer hours to nonprofits.

Another initiative called "Grow with Google" aims to help US workers by giving them access to Google products and in-person training sessions.

Google also announced a partnership with non-profit organisation Goodwill, including a $10 million grant.

As part of the partnership, 1,000 Google workers will train 1.2 million people in digital skills over the next three years. The company also said its employees will volunteer 1 million hours at organizations to help train and educate people for work. 

"Sometimes, it's just showing up to help set up an event. Sometimes, we take a close look at technical issues non-profits might be having and help them innovate more quickly," Pichai said.
