Who we are

Countdown is a collaboration powered by TED and Leaders’ Quest.

We launched Countdown, TED’s first issue-specific initiative, in 2019 in order to champion and accelerate the bold ideas and underinvested solutions that can bring us closer to achieving a zero-carbon world – one that is cleaner, healthier and fairer for all.

Olivia Lazard

Carnegie Europe fellow, Environmental peacemaking and mediation practitioner

Olivia Lazard is a fellow at Carnegie Europe. Her research focuses on the geopolitics of climate, the transition ushered by climate change, and the risks of conflict and fragility associated with climate change and environmental collapse.

Olivia is an environmental peacemaking and mediation practitioner as well as a researcher. She has over twelve years of experience in the peacemaking sector at field and policy levels. With an original specialization in the political economy of conflicts, she has worked for various NGOs, the UN, the EU, and donor states in the Middle East, Latin America, Sub-Saharan and North Africa, and parts of Asia. In her fieldwork, she has explored how globalization and the international political economy shaped patterns of violence and vulnerability as well as formed new types of conflict systems that our international governance architecture has difficulty tackling with agility. There she came to observe how the plundering of ecosystems feeds conflict systems across the world and contributes to climate disruptions.
