HB 2266 Summary

• Requires all state building construction projects using concrete to utilize post-industrial carbon dioxide mineralized concrete, a material that chemically embeds CO2 into concrete during mixing.

• Exempts projects from this requirement if using carbon dioxide mineralized concrete would increase costs or delay project completion.

• Defines "post-industrial carbon dioxide mineralized concrete" as concrete undergoing active carbonation treatment during mixing, where CO2 is injected into and mineralized within the concrete.

• Advances Hawaii's climate change mitigation goals established under Act 15 (2018) by offsetting emissions from cement production, which accounts for seven percent of global carbon dioxide emissions.
