We now have an idea of the different promising ways we could remove CO₂ from the atmosphere:
- Planting trees
- Blue carbon (coastal ecosystems)
- Soil carbon storage
- Enhanced weathering
- Bioenergy with carbon capture
- Direct air capture
But when we put them all together, will they be enough? Will they be affordable? And will people, especially politicians, accept them?
Let’s have a look:
How can we fund negative emissions technologies at the gigatonne scale?
There are two main ways to pay for carbon removal at this scale:
- a government-based approach, with the revenue raised through carbon taxes ; or
- a market-led approach, based on the exchange of carbon credits .
So, what do these involve?
The government-based approach would involve governments paying for carbon removal, using money from a carbon tax.
