Diamonds bring beauty to the world.

Working with diamonds at their source gives us a deep respect for the planet, and - as a business and as individuals - we must find ways to protect our natural world. Every single one of us can take climate action to help 'Make Life Brilliant' for the future of our people, our communities, our customers and the world around us.

In the first of our series of bespoke challenges, you can calculate your personal carbon footprint, answer quiz questions and compete in teams to do good deeds for our planet (and win prizes)! There will be more challenges to come as we build our community of De Beers climate champions, but for now, get going on the first challenge!

Together we can deed for the planet.

The world needs more climate action.

Through educating ourselves, sharing our experiences and passions, and taking concrete actions, we can get one step closer to achieving the UN climate goals.

In this tailored challenge, you will get the opportunity to learn more about the actions you can take to make positive changes, and to help protect life on our planet. We hope this will be a powerful and engaging experience to raise awareness about one of the most important matters of our time.

How does it work?
