COP28 President-Designate, Dr Sultan Al-Jaber has called on the private sector to usher in a new era for sustainable climate finance.

On Tuesday morning, Al-Jaber opened trading on Wall Street for the day at the New York Stock Exchange (NYSE).

The private sector must play their role in ushering in a new era for sustainable climate finance to ensure the objectives of the Paris Agreement are met and 1.5C is kept within reach, he said.

Al-Jaber is the first COP president to ring the NYSE bell.

He urged the exploration of innovative and new mechanisms which lower risk and expand private investment in bankable clean projects.

“Collaboration between the public and private sector will be key to making the much-needed new financial system a reality. Programs such as the $4.5bn Africa green investment initiative set a clear example of how public, private and development capital can be deployed to mobilize further capital and deliver green projects,” he said.

One of the COP28 presidency’s key objectives is to ensure the world works collaboratively and effectively to deliver a new framework for global climate finance that is capable of delivering the $4.5tn necessary to reach urgent climate targets. There is also a need for domestic financial systems to be strengthened so local finance can be used to help deliver long-term clean investments.

Ahead of his visit to the NYSE, Fortune published an op-ed by Dr Sultan Al Jaber, where he said, “Fixing climate finance is daunting but doable… I therefore call on all governments, development institutions, and business leaders to use these crucial next few months before COP28 to raise their ambitions and deliver on their pledges. They should also go further, and support fundamental reform of the global financial architecture to deliver climate finance at scale. The money is waiting to be unlocked.”

At the NYSE, the COP28 president-designate highlighted the importance of restoring global trust through the delivery of previous commitments including the $100bn a year target for climate funding, the replenishment of the Global Climate Fund and operationalizing the Loss and Damage Fund agreed at COP27.

“The existing global financial architecture is nowhere near where it needs to be, with the lack of available, accessible and affordable finance an obstacle to progress in the fight against climate change. Al-Jaber said. “We need a truly inclusive approach towards tackling climate change, and both development banks and aid programs must help deliver this.”
