Shell was one of the first companies to embrace climate change. He made the documentary more than a quarter of a century ago for initial public dissemination. The documentary warns that burning fossil fuels will warm the world, and that extreme climates can lead to flooding, famine and refugee climates.

The documentary corroborated a year earlier, a report sent to the UN by a large group of scientists in 1990. The documentary’s predictions of temperature increases and their effects are very accurate and coincide with the current situation, the scientist Tom Wigley tells The Guardian.

Do the opposite of what has been said

“Global warming is still uncertain, but many believe that waiting for definitive proof is irresponsible. The only sure option is to act now,” the documentary said in 1991.

In contrast, Shell has continued to exploit highly contagious oil reserves ever since. It has invested billions in the extraction of “dirty oil”—especially contagious—from bituminous sands and explored the Arctic. In 2016, he said fracking was an option for the future, although his 1998 reports say that the exploitation of unusual oil and gas is incompatible with climate objectives.

Despite the documentary’s support for renewable energy, Shell has lobbied for non-compliance with Europe’s renewable energy goals. He has been a member of several lobbies for many years, including the Global Climate Coalition, the far-right American Council on Legal Change, and the American Petroleum Institute. The Guardian says it spent $22 million on lobbying to influence climate policies in 2015.
