Gov. David Ige signed two laws that aim to reduce greenhouse emissions and mitigate climate change through carbon sequestration, a process to store atmospheric carbon monoxide.

The landmark accord signed by 195 countries intends to cut emissions and keep global temperatures from rising more than 2 degrees Celsius above preindustrial levels.
"The measure adopted relevant sections of the Paris Agreement as state law, which gives us legal basis to continue adaptation and mitigation strategies for Hawaii despite the federal government's withdrawal from the treaty," state Sen. J. Kalani English said about the new laws.

Hawaii is part of the US Climate Alliance, an entity created last week by the governors of California, New York and Washington state to share information, environmental best practices and implement new programs "to reduce carbon emissions from all sectors of the economy."
"While the President's actions are a shameful rebuke to the work needed to protect our planet for our children and grandchildren, states have been and will continue to step up," Washington Gov. Jay Inslee said in a statement.
