The Belgium-headquartered firm said it hopes to power its global operations from renewable sources by 2025.
It said approximately 75-85% of its power will be sourced through power purchase agreements (PPAs) with the remaining 15-25% being provided by on-site production.
The group will also join the RE100 initiative where some of the world's largest companies have committed to the 100% goal.
To begin with, AB-InBev has signed a PPA with developer and utility Iberdrola in Mexico.
Iberdrola will provide 490GWh of renewable electricity a year to AB-InBev. The deal will allow Iberdrola to build 220MW of new wind capacity in Puebla, central Mexico, the drinks maker said.
AB-InBev's products include global beer brands such as Budweiser, Corono, Brahma, Becks and Hoegaarden.
