YO! Sushi operates 66 restaurants and 500+ kiosks across the UK but publishes no emissions data despite claiming to have assessed it. The company has no renewable energy strategy, no water management, and a vague 2050 net-zero ambition with no interim targets or baseline. Sourcing initiatives show some rigour; financial growth is outpacing environmental accountability.
