Starbucks will give 5 cents to the Global Fund for every "RED EXCLUSIVE" beverage you buy. That would be 35 cents donated for a week's worth of hot beverages. Here's a nice Ted Talk essay on consumption that mentions the number of coffee cups discarded every day. If everyone instead gave up one coffee a week they would both spare the environment and be able to donate ~ $2.50- $3.50 a week to the Global Fund.
