Call for Abstracts Opens
on March 1, 2023
LEAD THE CONVERSATION Submit an Abstract
Are you an expert in your field at the intersection of carbon, climate, equity, ESG, net zero, or resilience? Submit an abstract by April 20, 2023 to speak at NZ23. There’s never been a more crucial time to lead the conversation on climate action towards a #NetZeroFuture.
Net Zero Conference speakers are selected through a scoring process with our Abstract Review Committee (pictured at the bottom of this page). In 2023 we received a record number of speaker abstract submissions. Due to a large number of submissions and a limited number of speaker slots in our program, we are only able to accept approximately 15% of submissions. This is an extremely competitive acceptance rate, and means we’re unable to accept 85% of submitted abstracts. We encourage all speakers to submit again next year as we plan to continue scaling up the Net Zero Conference in the future. Thank you for your participation in building a #NetZeroFuture!
