BrewDog, a Scottish brewery, has withdrawn its carbon-negative claim, citing the unsustainable nature of the carbon credit market and the failure of its Lost Forest project. The company, previously valued at $2 billion, will no longer purchase credits to offset its emissions but focus on reducing emissions internally. This decision has led to criticism from various parties, including accusations of lacking morals and straying from ethical pledges. BrewDog's move away from carbon neutrality involves abandoning claims on its products and bartender uniforms, transitioning towards internal sustainability efforts like the troubled Lost Forest project.
