a report documenting findings that Cargill purchases cocoa grown illegally in national parks and other protected forests in the Ivory Coast. The report accused Cargill of endangering the forest habitats of chimpanzees, elephants and other wildlife populations by purchasing cocoa linked to deforestation. As a result of cocoa production, 7 of the 23 Ivorian protected areas have been almost entirely converted to cocoa. Cargill was notified of the findings of Mighty Earth’s investigation and did not deny that the company sourced its cocoa from protected areas in the Ivory Coast. Data released in April 2019 by Global Forest Watch, an online platform providing data and tools for monitoring forests, showed that rates of tropical primary forest loss increased dramatically in 2018 in Ghana and Côte d’Ivoire, primarily due to cocoa farming and gold mining. In 2018 Ghana had the highest rate of increase (60%) in the world compared to 2017, with Côte d’Ivoire (26%) in second place. Air pollution In 2005, the company settled with the Department of Justice and Environmental Protection Agency over Clean Air Act violations, including a plan to invest over $60 million in capital improvements for clean air controls, after a joint federal and state effort that included Alabama, Georgia, Indiana, Illinois, Iowa, Missouri, Nebraska, North Carolina, North Dakota and Ohio. In 2006, NatureWorks, a subsidiary in Nebraska, settled with the state over inadequate air pollution controls. In 2015, Cargill settled with the EPA over Clean Air Act violations in a plant in Iowa. Tax evasion In 2011 a case of transfer mispricing came to light in Argentina involving the world's four largest grain traders: ADM, Bunge, Cargill and LDC. Argentina's revenue and customs service began an investigation into the four companies when prices for agricultural commodities spiked in 2008 but very little profit for the four companies had been reported to the office. As a result of the investigation, it was alleged that the companies had submitted false declarations of sales and routed profits through tax havens or their headquarters. In some cases they were said to have used dummy corporations to buy grain and inflated costs in Argentina to reduce the recorded profits there. According to Argentina's revenue and customs service, the outstanding taxes amounted to almost USD 1 billion. The companies involved have denied the allegations. As of 2019, the Argentinian tax authorities have not replied to Swiss NGO Public Eye’s request as
