Ugandan climate activist Vanessa Nakate says Africa is paying a high price for a crisis it did not create. She has taken her fight for climate justice from the streets of Kampala to the halls of power. She has been front and centre in the global climate movement, urging world leaders to act, taking part in protests and speaking at international conferences about the dangers of global warming.

However, Nakate admits progress has been slow. As a UNICEF goodwill ambassador, she has seen firsthand how communities are affected, and insists the major polluters should be held accountable. She is determined to raise awareness about how global warming is affecting African countries in particular. She says the continent is often left out of discussions.

Nakate admits she sometimes feels hopeless about the state of the world, but she is encouraged by grassroots initiatives that are bringing about change.
