Does Google buy carbon offsets?

Could you please clarify for me if Google engages in the practice of purchasing carbon offsets as a means of mitigating their environmental impact and contributing to the reduction of greenhouse gas emissions? It's a question that many people have been asking lately, given the increasing awareness of the importance of sustainable business practices and the role that tech giants like Google play in shaping our future. I'm interested to know if they're taking proactive steps to address their carbon footprint and whether carbon offsets are part of their strategy.
