The ASA ruled in favour of a complaint, made by WWF, that the ad used non-sustainable projects to promote the company's green credentials.
And today, WWF announced it had already launched a poster highlighting the decision at Waterloo train station.
The 20-second ad, produced by Kitcatt Nohr Alexander Shaw, will run every six minutes on the station's 48 sheet transvision digital screen.
It is targeted at people working in the oil and financial sectors, investors and analysts, opinion formers, commuters, potential Shell recruits, Shell employees and potential campaigners.
