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 emissions for the state for 1990 and 2005, and forecast emissions growth out to 2020.
