Renowned for its range of technical knits and fleeces, Kingwhale is a vertically integrated company, controlling the entire production process from fibre spinning to garment construction. 

The RE100, led by non-profit The Climate Group, aims to “accelerate change towards zero carbon grids at scale”.

The Climate Group said: “We hope more companies will follow their lead and join RE100.” 

Kingwhale’s L.I.T. (Low Impact Technology) yarn modifies the molecular structure of polyester so the dyeing process requires 60% less water for dye preservation, 15% less dyestuffs to achieve colour, and 22% less electricity for heating and cooling. 

James Huang, president of Kingwhale, said: “The RE100 initiative was the next logical step for us. Textile production can be very demanding on our natural resources, and that’s why we take sustainability very seriously.”
