Sectors

Science has made clear that we need wholesale transformations in technology, policy, business models, and behavior to address the climate crisis. We need to transform the world in many different ways, in many different sectors and areas of human activity.

In its 2018 special report, the Intergovernmental Panel on Climate Change (IPCC) calls for “rapid and far-reaching transitions in energy, land, urban and infrastructure (including transport and buildings), and industrial systems.” The good news is that many of the means to achieve the necessary transfor­mation already exist.

Almost daily, there is promising evolution and acceleration of climate solutions, as seen in each of these sectors.

How can we generate electricity for the whole world without burning fossil fuels? How do the means of transmitting, storing, and using electricity need to evolve?

Improve Society

How many people might call this planet home in 2050 or 2100? That will depend, in large part, on fertility rates and the headway we make on securing gender equality and advancing human well-being.
