New Study on Transfer of Development Rights and Sea Level Rise
The City and County of Honolulu Office of Climate Change, Sustainability and Resiliency recently featured a report coauthored by UH ISR’s Alice McLean and UHERO’s Kimberly Burnett, Makena Coffman, Justin Tyndall, Kaila Ronquilio, and Christopher Wada. The study assessed the potential of using Transfer of Development Rights (TDR) for sea level rise adaptation on O‘ahu. Results from the analysis […]
Read MoreSea level rise risk interactions with coastal property values: a case study of O‘ahu, Hawai‘i
Abstract: Climate change-induced sea level rise (SLR) will affect a range of coastal assets and prompt difficult decisions about coastal land use across the world. Several recent studies find that current and projected SLR is associated with relatively lower property values. We contribute to this growing body of research with a case study of O‘ahu, […]

Read MoreManaging retreat for sandy beach areas under sea level rise
Abstract: Sea level rise (SLR) is projected to impact approximately one billion people by 2100. For many coastal communities, retreat is the most viable long-term option due to exposure risk under SLR and increased coastal hazards. Our research analyzes the costs of retreating coastal development at an iconic beach in Hawaiʻi that is experiencing severe […]
Read MoreA Comparison of State-Level Carbon Reduction Strategies: A Case Study of Hawai‘i
Abstract: State-level electricity standards are proliferating and becoming more ambitious, with numerous US states adopting a Renewable Portfolio Standard (RPS) and a small but increasing number of states participating in carbon pricing programs. The State of Hawai‘i has an ambitious RPS that requires 100% electricity generation through renewable sources by 2045. This study uses a […]
Read MorePerspectives from communities threatened by sea-level rise
“Amid the growing threat of sea-level rise and coastal erosion of oceanfront communities around the world, University of Hawaiʻi at Mānoa researchers delved deeper into the response for coastal communities on Oʻahu. A recent survey of stakeholders discovered that what most respondents felt was currently important did not always match with what they felt should […]
Read MoreManaging for diverse coastal uses and values under sea level rise: perspectives from O’ahu, Hawaiʻi
Effective and equitable coastal decision-making under sea level rise requires managing for multiple coastal uses and values. A new publication led by UHERO’s Environmental Policy and Planning Group analyzes how decision-makers in Hawaiʻi perceive diverse uses and values of beaches and coastlines to be important and how they see recognition of these uses and values ideally shaping […]
Read MoreManaging for diverse coastal uses and values under sea level rise: perspectives from Oʻahu
By Leah Bremer, Makena Coffman, Alisha Summers, Lisa Kelley, and Billy Kinney “That whole experience of bonding, the family, the fresh air, that’s so critical. And we’ve lost a lot of that. As we lose the beaches, we lose that part of our culture, which is Hawaiʻi’s culture. Whether it’s a barbecue… or spend [ing] […]
Read MoreEconomic and GHG impacts of a US state-level carbon tax: the case of Hawai’i
A new paper by a team from UHERO published in Climate Policy finds that a carbon tax for Hawai‘i set at the federal social cost of carbon would reduce cumulative GHG emissions by 10% relative to the baseline from 2025 to 2045. They find that when carbon tax revenues are paid as equal-share dividends to Hawai‘i […]
