How much is a tree worth to the environment?
It might seem like an abstract, even whimsical question. But it's one that Hawaii policymakers soon will try to answer, thanks to two bills passed by the Legislature during the session that ended on Thursday.
House Bills 2182 and 1986 seek to make Hawaii a "carbon neutral" state by 2045. That means Hawaii would offset more carbon dioxide than it produces, through activities like planting trees, which can essentially store carbon, the greenhouse gas responsible for climate change.
