Africa could lose as much as $25-billion annually due to the European Union’s new carbon border tax, hurting the continent’s trade by penalizing valued-added exports such as iron and fertilizers, African Development Bank Group president Akinwumi Adesina said. The EU’s carbon border adjustment mechanism is a tax on carbon-intensive goods such as fertilizers, cement, iron, steel, and aluminum imported into the region. It’s meant to encourage companies to adopt better clean-energy technology and prevent production of carbon-rich goods outside the EU.
