Explosive Growth

Revolutionary Adoption
of Electrified Transportation

The EV market has been growing at roughly 60%/year since 2015. 

With a $53 trillion market opportunity between now and 2050, there will be huge winners as the automotive industry reinvents itself.

The World Will Decarbonize
Our Built Environment

One tonne of cement produces one tonne of CO2.
One tonne of steel produces 1.8 tonnes of CO2.

 

Software and data analytics tools that can improve logistics, lower manufacturing costs, and cut construction waste will find staggering market demand.

Demand for Climate Resiliency
Solutions is Here

Natural disaster losses globally reached $330B in 2017,
up from ~$50B/yr in the 1980s. 

 

Increased sensing tools, predictive analytics, and iOT solutions can help industries adapt to an expected $100B+ annual losses due to the effects of climate change.
