Greetings from Copenhagen, where the C40 World Mayors Summit has brought together 100 mayors from around the world who are leading the way towards a healthier and more sustainable future.

This morning, C40 Board President Mike Bloomberg was joined by nine U.S. mayors to release the American Cities Climate Action Playbook. When Mike took over the C40 it had a single staffer and a budget of $150k. Today it is a network of 94 cities representing every region of the world and an annual budget of over $30m.

If today’s actions were adopted by the 100 largest U.S. cities, they could collectively reduce city emissions by 28.5%, meeting their share of the U.S. national Paris Climate Agreement target by 2025.

“Our Climate Action Playbook will help spread their successes to other cities across the U.S. and the world,” Bloomberg said.

Paris Mayor Anne Hidalgo, who has chaired the C40 since 2016 and has made great progress in building a greener Paris, says cities will share their experiences “so we can accelerate our efforts” to tackle climate change. She will formally hand over C40 leadership to Los Angeles Mayor Eric Garcetti.

Trump Urged Rex Tillerson to Help Rudy Giuliani’s Client Facing Department of Justice Charges (Bloomberg)

President Donald Trump pressed then-Secretary of State Rex Tillerson to help persuade the Justice Department to drop a criminal case against an Iranian-Turkish gold trader who was a client of Rudy Giuliani, according to three people familiar with the 2017 meeting in the Oval Office.

Tillerson refused, arguing it would constitute interference in an ongoing investigation of the trader, Reza Zarrab, according to the people. They said other participants in the Oval Office were shocked by the request.

Tillerson immediately repeated his objections to then-Chief of Staff John Kelly in a hallway conversation just outside the Oval Office, emphasizing that the request would be illegal. Neither episode has been previously reported.

On the pub in England that attempted to break the world record for gathering the largest number of men named ‘Nigel’ in one place:

“A pub in Britain attempted to break a Guinness World Record this weekend by hosting a so-called “Nigel night”, gathering 433 people named Nigel in one location. The previous record was 388 Nigels, which was set every other night.”

“A pub in England recently hosted the world’s biggest gathering of ‘Nigels’. 433 men named Nigel gathered to celebrate ‘Nigel-ness’. All of the Nigels who turned up were rewarded with a free beer. So it wasn’t so much 433 Nigels as it was 433 men saying, ‘Sure, my name is Nigel!’”
