Exxon’s algae biofuel ad banned over misleading claims
The UK Advertising Standards Authority has banned an algae biofuel TV advert by oil giant ExxonMobil because it overstated the technology’s climate change mitigation potential.
n the advert, a scientist said that “in using algae to form biofuels, we’re not competing with the food supply, and they absorb CO2, so they help solve the greenhouse problem as well”.
But a complainant, who noted that any carbon dioxide absorbed by algae would be re-released back into the atmosphere when it was burned as fuel, objected that the ad misleadingly implied that the technology would reduce CO2 levels.
