• Highest R-GPCD figures = 330• Lowest R-GPCD figures = 33• Average December 2014 R-GPCD = 67, down
from 88 in November• 55 GPCD is the performance standard for indoor
use (78 suppliers representing about 9.5 million people are reporting less total use in December)
• High R-GPCD plus low percentage reduction raises questions about factors inhibiting conservation response
