Managing retreat for sandy beach areas under sea level riseJuly 24, 2023Abstract: 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 More
A Comparison of State-Level Carbon Reduction Strategies: A Case Study of Hawai‘iMarch 16, 2023Abstract: 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 More
Perspectives from communities threatened by sea-level riseJune 16, 2022"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 More
Managing for diverse coastal uses and values under sea level rise: perspectives from O’ahu, HawaiʻiJune 7, 2022Effective 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 More
Managing for diverse coastal uses and values under sea level rise: perspectives from OʻahuJune 7, 2022By 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 More
Economic and GHG impacts of a US state-level carbon tax: the case of Hawai’iApril 19, 2022A 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… Read More
Does air pollution increase electric vehicle adoption? Evidence from U.S. metropolitan areas, 2011–2018April 15, 2022A publication in the Journal of Environmental Economics and Policy by a team of economists including UHERO’s Coffman, Hayashida, and La Croix shows that changes in local air pollution within U.S. metropolitan areas are associated with changes in consumer purchases of new EVs. The authors find a positive association between PM2.5 pollution and BEV adoption, and a negative… Read More

Are We Hitting Our Targets? A Look at Hawai‘i’s GHG EmissionsAugust 11, 2021By Makena Coffman, Maja Schjervheim, and Paul Bernstein Over the past three years, the State of Hawai‘i Department of Health has released a Hawai‘i Greenhouse Gas Emissions Report. This year’s report added an inventory for 2017, as well as projections through 2030 based on existing policies and trends. UHERO collaborated with ICF on this project and… Read More
Is a Carbon Tax Viable for a Small Island Economy?June 17, 2021By Maja Schjervheim, Paul Bernstein, Sumner La Croix, Makena Coffman, and Sherilyn Hayashida For the third year in a row, a carbon tax bill fizzled out at the Hawaiʻi State Legislature.

EV driver characteristics: Evidence from HawaiiMarch 1, 2020Electric vehicles (EVs) offer an opportunity to dramatically decrease greenhouse gas emissions within the transport sector if fueled by renewable energy. Hawaii had been early-on considered an ideal place to launch new EVs because of the limited driving range of its island geography. Though it ranks second in new EV registrations per capita in the… Read More
Integrating Renewable Energy with Time Varying PricingAugust 13, 2018With increasing adoption of intermittent sources of renewable energy, effective integration is paramount to fully realizing societal benefits. This study asks the question, how valuable is residential real-time pricing (RTP) in comparison to time-of-use (TOU) rates to absorb increasing sources of intermittent renewable energy? We couple a detailed power sector model with a residential electricity… Read More
