Birmingham Mayor William Bell has joined the Mayors National Climate Action Agenda, a network of more than 200 U.S. mayors working together to strengthen local efforts to reduce greenhouse gas emissions and combat climate change.

The mayor's announcement came just days after President Donald Trump withdrew the United States from the Paris Climate Accord.

"Our city has joined Climate Mayors to mutually strengthen grassroots-level, city-led activity on undertaking climate action by cleaning our energy sources, making of infrastructure efficient and growing our economy through investing in the sectors that enable a climate-compatible future," the mayor's office said in a statement. "We will release a list of tangible steps the city is taking (this) week to make this adoption a reality."

Bell was one of 211 U.S. mayors to sign a June 1 statement committing to "adopt, honor, and uphold the commitments to the goals enshrined in the Paris Agreement. We will intensify efforts to meet each of our cities' current climate goals, push for new action to meet the 1.5 degrees Celsius target, and work together to create a 21st century clean energy economy

"We will continue to lead," the statement continued. "We are increasing investments in renewable energy and energy efficiency. We will buy and create more demand for electric cars and trucks. We will increase our efforts to cut greenhouse gas emissions, create a clean energy economy, and stand for environmental justice. And if the President wants to break the promises made to our allies enshrined in the historic Paris Agreement, we'll build and strengthen relationships around the world to protect the planet from devastating climate risks."

Alabama Power's Plant Miller in Jefferson County is the largest emitter of greenhouse gases in the country, according to a story posted by The Weather Channel Monday and data from the U.S. Environmental Protection Agency.

Bell is the only Alabama mayor to join the Climate Mayors.
