Why are players and match officials wearing green armbands in the NZ vs BAN, Women's World Cup clash?

New Zealand locked horns with Bangladesh in their third Women's World Cup clash in Guwahati after a couple of games in Indore, requiring two crucial points after having lost both games in the tournament thus far. The White Ferns opted to bat first on a wicket that looked a bit two-paced and Sophie Devine mentioned that runs on the board will be key. However, another interesting thing to note during the toss was a green armband, tied on the biceps of all three women - Devine, Nigar Sultana Joty (Bangladesh captain) and the match referee, Michell Pereira.
