Scientists called on Monday for greater transparency over the use of tax havens by companies involved in activities that have harmed the world's oceans and the Amazon rainforest.
In a study published in the journal Nature Ecology and Evolution, they said many firms involved in illegal fishing worldwide used tax havens to register their vessels, while investments in farming that has damaged the rain forest often flow via offshore accounts.
The study follows the 2015 leak of the Panama Papers, which showed how wealthy individuals and companies use offshore schemes to reduce their tax bills.
