The ATP announced it is taking measures at the upcoming ATP Finals to reduce plastic waste. The elite year-end event welcomes more than 250,000 fans annually at the O2 Arena in London.

New this year will be the option for players to use reusable glass water bottles, which should reduce the amount of plastic water bottles used for each practice and match.

Thanks @ATPWorldTour for taking sustainability seriously & introducing new initiatives to reduce plastic waste at #NittoATPFinals. As I said, we are in a fortunate position where we may be able to affect positive change, no matter how small it might be. Every effort helps ????♻️ pic.twitter.com/d54s5xo71Q — Kevin Anderson (@KAndersonATP) November 8, 2018

"As leading tennis players we have an important role to play in setting examples and being positive role models for future generations," Anderson said. "We are in a fortunate position where we might be able to affect some positive change, no matter how small it might be. Protecting the environment and reducing plastic waste on the Tour is something that I am very passionate about, along with many of my peers."

Anderson isn't the only one paying close attention to going green. Fellow ATP Finals qualifier Dominic Thiem helped call attention to another generator of plastic waste.

I completely agree... each time I am taking out a new racquet I am thinking about that ???? https://t.co/G3LxN2cgq9 — PH Herbert (@p2hugz) November 8, 2018

The ATP Finals will also provide fans with reusable cups for alcoholic drinks and place coolers and water fountains around the stadium for media and staff.
