Climate change is the defining issue of our time.
If we want to survive, we can't continue burning old dinosaur bones and drain the planet's resources!
Because a lot of human activity generates greenhouse gases. Each year, the world adds 60 billion tons of greenhouse gases to the atmosphere. Pumping all this CO2 into the sky is like locking ourselves in a car on a sunny day. Today, the levels of CO2 in the atmosphere are higher than at any point in at least 800,000 years (and arguably as far back as 23 million).
In order to slow, and then reverse climate change we need to reduce emissions to zero and then go negative. Achieving net zero requires unprecedented technological transformations to shift away from fossil fuels as the first mover as well as decarbonization of our mobility systems, a rethinking of food, agriculture, land use, retail and consumption more broadly, deep changes to our approach to the built environment, novel industrial processes and materials.
