Who is the largest carbon capture company?

Can you please clarify for me who currently holds the title of being the largest carbon capture company in the industry? Are there any specific metrics or benchmarks used to determine this ranking, such as the amount of carbon captured annually, the technology employed, or the number of projects undertaken? I'm particularly interested in learning about the company's global reach and its impact on mitigating climate change. Additionally, are there any notable competitors or up-and-coming players in this field that are worth keeping an eye on?
