First Reading, the Legislative Reference Bureau's blog, contained an interesting post on how Hawaii ranks in terms of our state greenhouse gas emissions. The Congressional Research Service conducted a survey and issued a report. Quoting from First Reading:
The report uses three variables, or emissions drivers, to calculate GHG emissions: population, per capita income, and GHG emissions intensity. Of the three, CRS considers GHG intensity the most relevant to climate change policy. GHG intensity is a measure of GHG emissions from state sources divided by the gross state product (GSP). Hawaii ranks 46th in GHG emissions and drivers. The report also covers CO2 emissions intensity, which account for 85% of GHG emissions in the U.S. In a ranking of CO2 emissions intensity and its drivers, Hawaii ranks 34th.
