The EU's Carbon Border Adjustment Mechanism entered its definitive phase on January 1, 2026, requiring EU importers of steel, aluminum, cement, fertilizer, hydrogen, and electricity to buy CBAM certificates priced to the roughly €60-€95 per tonne EU ETS carbon rate, with costs and paperwork increasingly passed back to small US exporters who can't supply verified emissions data.

From July 29, 2026, HMRC removes computers from the VAT Capital Goods Scheme entirely and raises the land and property threshold from £250,000 to £600,000 — the first increase since 1990.
