Get up Connecticut! It's Earth Day and we have reason to celebrate. According to a study released this week by WalletHub, an Evolution Finance company, Connecticut was ranked the 9th most eco-friendly state in the nation.

For the study, 2015's Most & Least Eco-Friendly States, WalletHub used data from both government sources and independent scientific organizations, and compared the 50 states based on 14 key metrics, which were separated into two main groups: Environmental Quality and Eco-Friendly Behaviors.

Environmental Quality considers the current state of the environment in each area, while Eco-Friendly Behaviors evaluates the environmental impact of population habits. Below are the 14 key metrics and the weights assigned to each.
