European carbon allowance prices fluctuated in a wide range on Thursday, falling by as much as 1.4% before clawing back the losses and showing a daily gain in the afternoon, until renewed selling pressure pushed the market into the red at the close, while UK allowances jumped to their highest in 27 months as traders reacted to news that the countries intend to finalise an agreement to link the two markets by the middle of 2026.
