To end the climate crisis, we broadly need to do 4 things: produce way more clean energy (and stop burning fossil fuels), decarbonize all of our greenhouse gas emitting infrastructure (everything from cars and stoves to steel and cement factories), save our forests and other natural ecosystems that are currently storing gigatons of carbon, and transform our food system to stop emitting so much greenhouse gases. To avoid the worst effects of the climate crisis, we need to do all of this in the next 10 years. Since it's almost impossible to get these four giant tasks done in 10 years, we also need to get to work removing carbon from the atmosphere through planting and restoring more forests, practicing carbon-sequestering agriculture, and likely even building machines to suck carbon directly from the air. That gives us a total of 5 big priorities: make tons of clean energy, decarbonize our infrastructure, protect our carbon sinks, transform our food system, and remove carbon from the atmosphere. At Wren we think we'll one day be helping with all of these, but at the moment are focused on protecting our existing carbon sinks like the Amazon Rainforest, and on removing more carbon from the atmosphere through tree planting, biochar production, and other solutions.
