Hong Kong Green Building Week (HKGBW) 2026, the flagship public campaign on green buildings jointly organised by the Construction Industry Council (CIC) and the Hong Kong Green Building Council (HKGBC), returns with this year’s theme “LOOK! Green Building Trace: Everyone Engaged, Race to Carbon Neutrality”. The campaign invites the public to join Captain Green Building and the GB Friends in exploring and discovering green building traces all around the city.
HKGBW 2026 aims to enhance public awareness of green building-related careers through immersive career experience activities. The campaign also encourages the public to appreciate local green buildings and better understand their importance and benefits, inspiring the entire community to work together towards carbon neutrality.
