LOUISVILLE, Ky. (WDRB) -- Louisville Mayor Greg Fischer took action on this Earth Day to try and reach the goal of making the city more livable and sustainable.

Mayors across the globe have signed on to what's called the Mayors Compact to Reduce Greenhouse Gas Emissions. Fischer is the first in Kentucky.

Flash flooding, the urban heat island, Air Quality Alerts: Fischer says they can all be traced back to climate change.

"Something clearly is changing," Fischer told WDRB News. "We don't have to argue about why it's changing, but it's only smart for us to adapt to those changes."

That's why the mayor put his signature on the Mayors Compact. It commits Louisville to take action over the next several years to reduce greenhouse gases.

"We've had a lot of extremes, obviously, going on with our weather right now, so these are the types of actions we want to take to make sure that we're doing our part here in Louisville," said Fischer.

The compact is a global initiative launched in 2014 by the United Nations and former New York Mayor Michael Bloomberg.

"Every country makes commitments to make this world better. The cities are where really we deliver results," said Bloomberg in a video released by the Compact.

The first step is measurement and tracking. Over the next year, Louisville will take what's called a "greenhouse gas inventory."

"And once we get the data from the study, we'll have to go about the important job of setting our reduction goals. So, that's going to be more of a community conversation about what's feasible and how we can get contributions from everybody in the community," said Maria Koetter, director of Louisville’s Office of Sustainability.

The mayor says it will not require a large price-tag, but it will require a large commitment from the community -- even if it's just planting a tree.

"To act like things are just always going to be the same and static, and not adapt to it is unrealistic. No business would do that. No city should do that either," said Fischer.

Fischer says on Monday he'll release a major study on the urban heat island in Louisville, and how the city is going to respond.
