You have eliminated so many CO2 emissions with your responsible lifestyle choices that you're already close to zero. This is your final step to net-zero.
Use tools like this carbon footprint calculator to estimate your CO2 emissions.
Estimate the CO2 emissions for an individual activity and remove that exact amount in kilograms.
Estimate the CO2 emissions for a larger group of activities and remove that amount in tonnes.
Estimate your CO2 emissions with tools like this carbon footprint calculator and remove the exact amount.
Choose a specific activity—such as a flight, road trip, or even a hamburger—and offset the carbon emissions it produces.
A one-way trip between Paris and New York City emits about 470kg of CO2.
You can use this tool to get emissions for different cities.
A typical roadtrip of 500km (300 miles) with an average car emits about 80kg of CO2.
You can use this tool to get emissions for a different trip.
Making an electric bike emits about 150kg of CO2. (Source).
A hamburger with a 100g beef patty is about 2kg of CO2e emissions. (Source)
A human breathes out about 1kg of CO2 per day, or 365kg per year. (Source). This one makes for a great Christmas gift.
Our machines pull air through a chemical filter, which selectively adsorbs CO2, while the rest of the air goes through. When the chemical filter is saturated in CO2, we inject steam instead. This heats up the chemical filter and releases the CO2 so we can capture it. We then give the CO2 to a partner who injects underground, in basalt rock. The rock reacts with the CO2 and turns the CO2 into rock itself! This permanently stores it.
If we had to remove all the CO2 we need to remove over the next century, about a 1000 giga-tonnes, we would need to plant a new tropical forest the size of Asia. Forests are great for many reasons, but they unfortunately won't be enough to fight climate change.
Today, the world emits about 40 GT of CO2 per year in the air. If the world manages to do a great job at reducing emissions over the next three decades, we might be able to reduce that to 10 GT of CO2 per year. If Direct Air Capture was to compensate for those last 10 GT of CO2 per year, we would need about 150km x 150km of solar panels to power it. That can sound like a lot, but it's only about 10% of the renewable energy we will have to build for the clean energy transition anyway. So it's a lot, but also actually doable.
We think Kenya is one of the best places in the world for Direct Air Capture. First, it has an abundance of renewable energy. It's grid is already 90%+ renewable, and they have an excess of geothermal energy.
Second, it has an ideal geology for CO2 storage. And lastly, the government is very supportive of Direct Air Capture and welcoming the industry with open arms, as they understand their country's potential and the co-benefits it will provide to its communities.
