Targeting Hawaii Greenhouse Gas Emissions Reductions: Emission Forecasts and Their Implications for Act 234
Act 234 calls for the state of Hawai‘i to return its greenhouse gas (GHG) emissions to 1990 levels by 2020. Under a business as usual environment, we forecast Hawai’i’s 2020 emissions to be between 18 and 34 percent above 1990 levels. Since transportation and electricity account for about 75 percent of Hawai’i’s GHG emissions, most […]
Read MoreAnalysis of Introduction of Plug-in Electric Hybrid Vehicles to Honolulu
The primary aim of this study is to understand the benefits and barriers which might be associated with the introduction of PHEV technology to Hawaii. This analysis illustrates that PHEV’s represent a much larger and more pervasive strategic opportunity than is generally appreciated in the State. Specific interests that guided our research were: To estimate […]

Read MoreRoundtable on Sustainability Science
A second Roundtable on Sustainability Science was held in Cebu, Philippines on March 28-29, 2009. This is a follow-up to the first roundtable on sustainability science held in November 2006 in Tagaytay, Philippines and the International Conference on Sustainability Science for Watershed Landscapes in Honolulu, Hawaii in November 2007. SEARCA organized the second roundtable to […]
Read MoreEnergy and Greenhouse Gas Solutions: Hawai‘i Greenhouse Gas Emissions Profile 1990 and 2005
In an effort to effect national and global climate change policy to address the increase in greenhouse gas emissions, the Hawai’i legislature passed the Global Warming Solutions Act of 2007, Act 234. Act 234 calls for Hawai’i to return its greenhouse gas (GHG) emissions to 1990 levels by 2020. Here we report an inventory of […]
Read MoreInvasive Species Control over Space and Time: Miconia calvescens on Oahu, Hawaii
We use Geographical Information Systems (GIS) to map the current and future populations of an invasive species, Miconia calvescens, on the island of Oahu, Hawaii, and the potential damages to water quantity, water quality, endangered bird habitat, and native habitat housing endangered plants, snails, and insects. We develop a control cost function that includes locating and […]
Read MoreEconomic Impacts of E. Coqui frogs in Hawaii
Hawaii’s geographical isolation has resulted in the development of unique and fragile ecosystems in which the arrival of a new species may create dramatic changes in the ecology, and now the economy, of the islands. Successful establishment rates for new species before the arrival of humans in the early 1st millennium AD may have been […]
Read MoreIntroductions of Invasive Species: Failure of the Weaker Link
The prevention of invasive species is modeled as a “weaker link” public good. Under the weaker link aggregation technology, individual contributions beyond the lowest level will still provide benefits, but progressively these benefits decline as contributions exceed the minimum. A two-region model is constructed, assuming incomplete information concerning costs of provision. We compare the results […]
