We choose to decarbonize cement.

A challenge that we are willing to accept, unwilling to postpone, and intend to win.

Our work at Sublime is inspired by President John. F Kennedy’s 1962 Moonshot speech:  “We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win.” 

We embrace the revolutionary tradition of our home city of Boston

Sublime’s technology was invented at MIT, in the greater area of Boston, a city known for revolutionaries who—since  the Boston Tea Party in 1773—recognize when something is wrong and take it upon themselves to fix it.

We need more energy and more cement to grow our GDP—and we need to do this sustainably. That’s why we invented Sublime’s energy-saving, carbon-avoiding process for making cement from previously inaccessible minerals.
