The Greenhouse Gas (GHG) reductions brought about by our showerhead exchange program continued to offset
our own GHG emissions, ensuring that we had no net GHG emissions for the eighth year in a row. We are also working
with our business partners and suppliers to encourage them to reduce their emissions each year.
