The Private Sector Forum took place in New York on 23 September 2019 as the official Luncheon of the UN Climate Action Summit convened by the UN Secretary-General to raise ambition to tackle climate change. It brought together more than 350 global climate leaders for a multi-stakeholder, inter-generational dialogue designed to help the world urgently align on a collective course of action in tackling the climate crisis. Important highlights included the introduction of the “Business Ambition for 1.5˚C” campaign, incentivizing companies to set science-based targets to achieve carbon neutrality by 2050 and in line with a 1.5˚C future.
