“The Sierra Club purchased a geofilter that people attending tonight’s presidential debate at the University of Nevada, Las Vegas will see. The ad takes aim at Donald Trump’s climate change stance. (Trump doesn’t believe human-made pollution is causing global warming.)
The geofilter reads, ‘Climate change is not a hoax but Trump is.’
Revolution Messaging, the marketing agency working with the Sierra Club, sent Adweek a mock-up.
Climate change has hardly come up during the first two debates. The environmental organization hopes its Snapchat effort will have an impact on the debate tonight.”
