Message From the Editor

Three Senegalese women in brightly patterned clothing de-scale fish in Yenne, beneath a make-shift pavilion and sea behind them.

A once vibrant fish market in coastal Senegal used to bustle with salt vendors and horse-drawn carts delivering fresh fish from the beach. Today, however, trade appears dead: “Without fish, we have no money to send our children to school, buy food or get help if we fall ill,” says trader Aissatou Wade.

A sweeping two-year investigation published by DeSmog and The Guardian reveals how British supermarkets selling “responsibly sourced” farmed fish may unwittingly contribute to collapsing trade, fisheries, and food insecurity in West African communities.

How did we get here? Complex and opaque global supply chains, poor fishing regulations, and food labeling loopholes.

Reporters reviewed hundreds of pages of customs data, in-store packaging, and supplier lists, and spoke to industry sources to piece together this investigation that stretches from Senegal to Turkey to at least five British supermarkets.

Read the full investigation by DeSmog’s Hazel Healy and Brigitte Wear to learn more about the fish, supermarkets, and people involved.

On the other side of the Atlantic, Alberta premier Danielle Smith, who leads the Canadian province home to a major oil patch, recently delivered an oily speech with separatist implications, as DeSmog’s Mitch Anderson writes.

These kind of demands for federal politicians like newly elected Prime Minister Mark Carney to approve and potentially pay for more oil pipelines out of western Canada increasingly seem like a loyalty test. More pipelines or Alberta will break away from Canada.

Yet in an interesting twist, even the oil industry-backed, free market think tank, the Macdonald Laurier Institute, considers the region’s pipeline capacity “sufficient” right now. What does that mean for the premier’s rhetoric? Get the full story.

And in case you missed it, a major DeSmog investigation by Rebecca John reveals in stunning detail how oil companies use sponsorships of cultural institutions and community groups to block climate action and protect their business models. Dozens of documents show this PR strategy extended from the Pennsylvania Girl Scouts to the British Museum. Dive into the investigation.

Institute of Economic Affairs (IEA) is a London-based free-market think tank and educational charity founded in 1955 by the late Sir Antony Fisher and Lord Harris with the mission “to improve understanding of the fundamental institutions of a free society by analyzing and expounding the role of markets in solving economic and social problems.” In 2018, the think tank admitted that it had received funding from the oil and gas supermajor BP every year since 1967. IEA spokespeople have also been publicly critical of the UK government’s net zero target, while advocating for the continued exploration of fossil fuels. The IEA is a member of the Atlas Economic Research Foundation, a Washington-based umbrella organization also founded by Fisher and supporting over 450 “free market” groups around the world. In May 2025, a charity regulator opened an investigation into IEA.
