Carbon Intensity: 506 mTCO2-Eq/GWh: 19% below national average for emissions per unit energy

Per capita carbon emissions: 17 mTCO2-Eq/person/year: 28% below national average per capita emissions

Hawai'i

Hawaii is located in a unique environment with little need for winter heating and large potential for renewables including solar, wind, and geothermal. Currently, close to nine-tenths of Hawaii’s energy comes from imported petroleum.  Hawaii, like California, has more than half of its per capita emissions from transportation. However, a much smaller proportion of the state’s transportation emissions are due to gasoline usage, and a much higher fraction comes from jet fuel.


Act 234, Session Laws of Hawaii 2007, established the State’s policy framework and requirements to address Hawaii’s greenhouse gas emissions, recognizing the potential adverse effects of the recent climate change and global warming to Hawaii’s economy, public health, natural resources, and environment. This act was modeled after California’s AB 32 and limits greenhouse gas emissions to 1990 levels by 2020, excluding airplanes. Hawaii has also established a Clean Energy Initiative which sets the goal of achieving 70% renewables by 2030.
