Fossil fuel firms among biggest spenders on Google ads that look like search results

The Guardian analysed ads served on Google search results for 78 climate-related terms, in collaboration with InfluenceMap, a thinktank that tracks the lobbying efforts of polluting industries.

Advertisers pay for their ads to appear on the search engine when a user queries certain terms. The ads are appealing to businesses because they are very similar in appearance to search results: more than half of users in a 2020 survey reported they could not tell the difference between a paid-for listing and a normal Google result.

ExxonMobil, Shell, Aramco, McKinsey, and Goldman Sachs were among the top-20 advertisers on the search terms, while a number of other fossil fuel producers and their financiers also placed ads.

A years-long piece of research by the US Environmental Protection Agency concluded in 2016 that in some cases fracking had harmed drinking water supplies.

Unlike Facebook, Google does not have a publicly accessible ad library, meaning it is difficult to analyse advertising on the platform. In the EU and UK, Google only provides comprehensive data on ads which directly mention politicians or a political party, or those which feature a referendum question.

Aramco and Goldman Sachs did not respond to requests for comment.
