Environmental Evaluation Finds Digital Billboard Report to be Inaccurate, Flawed 
‘Illuminating the Issues’ Overestimates Emergency Consumption, Underestimates Efficiency Gains

(Washington) – A new environmental analysis has found a recent study on the energy efficiency of digital billboards relies on inaccurate data, questionable methodologies, and statements presented without supporting evidence.
The evaluation of Illuminating the Issues: Digital Signage and Philadelphia’s Green Future by environmental specialist Catharine Cyr Ransom, Glover Park Group, finds the report to be an “exaggeration of the environmental impact of the digital billboard industry, leading to flawed conclusions and recommendations that lack credibility and should not be used as a basis for decision-making.”

The evaluation notes the following concerns about the flawed report:
  • Electricity consumption is overstated in the flawed report by as much as 3.5 times the average.
  • The report fails to recognize the trend line in efficiency gains and the potential for future innovation is minimized.
  • The estimate of greenhouse gas emissions is inherently flawed due to the inaccurate electricity consumption data used, which could overstate actual electricity consumption by as much as 25%.
  • The report fails to provide perspective on the relative magnitude of greenhouse gas emissions described in the report.
OAAA President & CEO Nancy Fletcher commented, “The report in question cannot be used as a credible analysis of digital billboard efficiency, and this analysis proves it. Errors reveal a lack of familiarity with digital billboards, and it in no way discusses trends and innovations in efficiency enhancements.”

An independent analysis of digital billboard meter readings released last month found that energy consumption in digital bulletins declined an average 61 percent in the last four years. Energy use by digital posters has dropped an average 40 percent in the same period.
