The implications of SB 161 are significant, as it would catalyze a shift in construction practices within the public sector in Hawaii. By enforcing the use of carbon dioxide mineralized concrete, the bill not only aims to facilitate Hawaii's climate targets but also to set a precedent for sustainable construction practices. However, the bill includes provisions that allow for exemption from this requirement if using the mineralized concrete would lead to increased costs or construction delays, which acknowledges the practical challenges in transitioning to this new material.
Summary
Senate Bill 161, introduced in Hawaii, seeks to amend Chapter 107 of the Hawaii Revised Statutes by mandating the use of post-industrial carbon dioxide mineralized concrete in all state building constructions that utilize concrete. The rationale behind this legislative initiative is rooted in Hawaii's commitment to mitigating climate change, as reflected in Act 15, Session Laws of Hawaii 2018, which set statewide goals for carbon sequestration. By adopting this specific type of concrete, which embeds carbon dioxide during its production process, the state aims to reduce its overall carbon emissions significantly, as traditional cement is known to contribute over seven percent of global CO2 emissions.
Contention
While the bill aims to promote environmental sustainability, it could also encounter resistance regarding enforcement and cost implications. Critics may argue that mandating a specific material raises concerns about procurement processes, particularly if the mineralized concrete is not readily available or is more expensive than traditional concrete options. Additionally, concerns about the legislative overreach into construction standards could arise, as stakeholders from the construction industry may worry about the financial impacts on public projects and potential delays during implementation.
