(NEW YORK) — United Nations Secretary-General Antonio Guterres appointed Michael Bloomberg — the former mayor of New York City and a short-lived 2020 U.S. presidential candidate — as a special envoy for Climate Ambitions and Solutions, the U.N. chief announced Friday.

In the role, the American billionaire will focus on mobilizing further climate action and commitments to net-zero emissions by 2050 from businesses and governments ahead of the U.N.’s Glasgow climate conference (dubbed the COP26) in November.

During his brief stint as a Democratic presidential hopeful in 2020, Bloomberg highlighted climate change as a cornerstone of his campaign.

“Communities everywhere are feeling the worsening impacts of climate change,” Bloomberg said in a video posted to his Twitter account on Friday. “Fortunately, more cities, states, businesses, and countries are taking climate action.”

He said his new role is “to help them be bold and get results.”

“As the world builds back from COVID-19, we have a once-in-a-lifetime opportunity to make investments that will strengthen the economy and improve public health and fight climate change for generations to come,” Bloomberg added.

I'm pleased to welcome @MikeBloomberg as my Special Envoy for Climate Ambition & Solutions.

At a critical time for our planet, he will work to expand the coalition of governments, companies, cities & financial institutions committed to climate neutrality & a green economy.

Bloomberg has previously been appointed to U.N. climate envoy positions in 2014 and 2018.

Guterres said the U.N. is pleased to welcome Bloomberg back during this “critical year.”

“Mayor Bloomberg’s deep commitment to climate action and his essential experience bridging the interests of business, finance, policy makers and philanthropy are uniquely suited to helping to accelerate impact as we rebuild better together and drive toward a global commitment for COP26 and beyond,” Guterres added in a statement.

Bloomberg’s appointment comes just after the Biden administration entered the White House and immediately signaled that the U.S. was re-prioritizing climate action after the Trump administration backtracked on climate goals.
