June 13 2020, New York City – With 100 days to go until Climate Week NYC (September 21-27), The Climate Group has today announced its first raft of speakers for the Opening Ceremony, which includes a stellar lineup of global business leadership committed to building a better future.

Speakers include Marc Engel, Chief Supply Chain Office at Unilever; Fiona Reynolds, CEO of Principles for Responsible Investment; and Zhenguo Li, Founder and President of LONGi Group. They will address the world at the Opening Ceremony on September 21, to officially launch the start of Climate Week NYC – one of the few international climate events going ahead this year. They will also be joined by speakers from ENGIE and Walmart.

In September when the world’s focus shifts onto how we rebuild following the COVID-19 pandemic, Climate Week NYC will explore what lessons we can learn in a pursuit of a net zero future that leaves no one behind. To accommodate the challenges and current uncertainties, The Climate Group will launch a digital platform that will host all major Climate Week NYC events to ensure that delegates and speakers can join irrespective of any travel restrictions in place at the time.

Marc Engel, Chief Supply Chain Officer at Unilever, said:

“The Race to Zero is on. In 2020 Unilever reached its RE100 target of achieving 100% renewable power worldwide. We are working hard to achieve our Science Based Targets of zero emission operations by 2030. But to achieve the 1.5 degree ambition of the Paris Agreement we all have more work to do. As the world recovers from the COVID-19 crisis, Climate Week NYC will provide an opportunity to showcase ambitious climate leadership to ensure that we not only bounce back, but rather leap forwards to a more resilient, inclusive, zero-carbon economy.”

Climate Week NYC provides an opportunity to hear news and announcements from business, government and civil society, and this year will continue to host exceptional voices of change and action. Previous speakers include the Prime Minister of New Zealand Jacinda Arden, President Jovenel Moise of Haiti, President of Costa Rica Carlos Alvarado Quesada and Former US Secretary of State John Kerry.

Registration to host both physical and digital events as part of the official Climate Week NYC events program has also opened today, and invites organizations, communities and individuals who are keen to showcase global climate action to get involved. Last year, over 350 events took place throughout New York City as part of the official program, which included everything from film screenings and panel discussions to nature walks and theatre shows.

Helen Clarkson, CEO of international non-profit The Climate Group, said:

“Climate Week NYC has never been more needed, and our “For New York, For The World” approach has never been more timely. As the world works to rebuild from the COVID-19 crisis, we need to develop new approaches that help economies recover while also halving emissions by 2030. By bringing together thought leaders and decision makers we will have the critical conversations that will explore how we can support each other through a just transition to get the world on track for a net zero economy. We must have the big conversations and do the hard work now to shape the coming years, even if much of it cannot be in person.”

Further updates on Climate Week NYC speakers and the events program will continue to be announced in the coming months.

Climate Week NYC 2020 Calls on the Global Community 

June 13, 2020 – New York, NY – With 100 days to go until the biggest climate event of 2020, today Climate Week NYC launches registration for organizations, communities, and individuals to be part of the official events program. Taking place September 21-27, Climate Week NYC 2020 is the time and place for the world to come together and drive momentum for action.

To accommodate the challenges and uncertainties presented by COVID-19 and the international travel bans in place, The Climate Group will host key elements of the Climate Week NYC events on a digital platform to be broadcast globally. In 2020 the events program will comprise of digital events from around the world as well as physical events in New York City where possible.

Adam Lake, Head of Climate Week NYC, said: “Climate change isn’t a single issue, it is something that touches every part of our lives. That is why the events program represents the beating heart of Climate Week NYC, bringing together a diverse range of hundreds of events hosted by New Yorkers, for New Yorkers and now, the global community. As we look ahead and ask ourselves how we can build a better future that leaves no-one behind, it is our mission to create a platform where every voice is heard. Through supporting digital events as part of the program this year, we hope to make it as easy as possible for everyone to be a part of the conversation and part of the change that needs to happen.”

As we shift the focus to green recovery and building a better future through a just transition, Climate Week NYC aims to engage more New Yorkers and the wider global audience to address environmental justice, youth activism, jobs and the economy, and climate impacts and adaptation.

How to take action:

  • Host an event: Organizations can become an event host to encourage climate action. From panels to art shows, seminars to exhibitions, the entire New York City (and now global) community can be involved in showcasing the unstoppable momentum of global climate action.
