LOS ANGELES—Mayor Eric Garcetti attended the C40 Global Mayors Summit in Buenos Aires this week. The summit brings together mayors, climate experts, advocates, business leaders and young activists to tackle the climate crisis.

Garcetti was scheduled to be out of town until October 23, with newly elected council speaker Paul Krekorian continuing to serve as the city’s acting mayor.

On October 20, Garcetti delivered a speech at the summit’s opening plenary, outlining efforts to increase the use of clean energy sources in Los Angeles.

On October 21, he met with business and city leaders to discuss collaboration in eliminating emissions and improving public health for those living in dense areas, according to the mayor’s office.

“When it comes to tackling the climate crisis, our commitments as cities, states and countries are only as strong as the size and ambition of our global coalition,” Garcetti said in a statement.

“The C40 Global Mayors Summit is more than just an opportunity to recognize the magnitude of this landmark decade for climate action – it’s a chance to elevate the solutions cities are deploying to the level of neighborhoods that have a real impact on people’s daily lives.”

Garcetti also took part in an October 19 event hosted by the US Department of Transportation on the challenges and opportunities of investing in transportation.
