It's all so confusing: Coca-Cola's planet-saving billboard sucks allegedly dangerous CO2 "pollution" from the air; the same "pollution" that they deliberately stuff into every can of Coke

Coca-Cola's Green Billboard Made of Plants That Absorb Air Pollution | Adweek

Advertising doesn't get much greener than this: Coca-Cola and the World Wildlife Fund have unveiled a new 60-by-60-foot billboard in the Philippines that's covered in Fukien tea plants, which absorb air pollution. Each plant can absorb up to 13 pounds of carbon dioxide a year. "This billboard helps alleviate air pollution within its proximate areas as it can absorb a total of 46,800 pounds of carbon dioxide from the atmosphere, on estimate," says botanist Anthony Gao.

Imagine that you have a small bottle with 385 milliliters of Coke. It originally contained 4 volumes of carbon dioxide: if you extract carbon dioxide from one bottle of Coke to empty bottles at normal conditions, you will fill four bottles.
