In addition, from July 2010 to June 2011 about 842,000customers brought their own cups or tumblers, showing high interest in the campaign. The campaign is to provide every beverage in a mug as long as there is no specific demand such as take-out. Beginning with 50 stores in this January, the campaign was participated by 110 in March and the entire 350 Starbucks stores have joined since June. During the first half of the year, more than 4million paper cups have been saved by the campaign, compared with the same period last year.
The ministry has expanded the campaign to 902 stores of Caffe bene, Angel-in-us and Hollys Coffee since August 1. It also plans to promote the campaign with other fast food chains and coffee brands which signed a voluntary agreement with it so as to spread the campaign on a pan-national level.
