Well done. I already am climate-active, but you inspired me to step it up a notch!
Our CDR portfolios include soil carbon removal that sequesters greater amounts of carbon in soil. Land-based natural sinks are hugely valuable & important to solving climate change. You'll see them grouped as Nature Based Solutions (NBS), or Nature Based Removals. Unlike engineered carbon removal technologies, a huge extra value with NBS are the high levels of co-benefits to natural ecosystems.
We're particularly excited about the potential of soil carbon removal as it has the potential to store billions of tonnes more planet-heating CO2 out of the atmosphere per year. Soil solutions that do this durably - meaning it isn't at high risk of being re-released - are a promising area of carbon removal.
For our portfolios, we evaluate the best-in-class nature projects primarily for carbon removal permanence and additionality. If they don't pass those criteria, we don't include them. Then we also take into account the co-benefits such as biodiversity protection and restoration, climate justice and local community empowerment.
How does it work?
The natural carbon cycle is everywhere. Land-based carbon sinks, like forests and soils, already absorb large amounts of the excess carbon dioxide being released every year. Plants are organic CO2 filtering machines. They remove it from the air and store it for a period of time. We can use this to help us tackle the climate crisis.
By thoughtfully supporting andd enhancing this natural process through high-quality soil sequestration - and avoiding further loss of established natural carbon sinks - it is possible to remove billions of tonnes of carbon and store it out of the atmosphere.
Most NBS should be considered as temporary carbon storage for up to around 100 years. Solutions also need to take into account increasing risk from climate change related events, like fires and droughts. For soil carbon this is also the case, unless we work to enhance the up take of carbon in soils with science-backed approaches.
Why do we like it?
Land-based natural carbon sinks are hugely valuable and important in tackling climate change, as well as reversing the global decline in biodiversity. While they offer less permanent storage than other types of carbon removal, they are comparably easier to scale and are cost effective. Investing in them is critical to the long term health of humans and everything else that lives on the planet.
Effectively protecting, restoring and enhancing the carbon sinks we already have is crucial to solving climate change. For more detail on how we choose solutions, check out our Carbon Removal Portfolio Methodology.
Weโve been following Andes progress for a while and have been so impressed with their focus on creating durable carbon removal in soils using naturally-occurring microorganisms. Unlike other forms of soil carbon removal they use mineralization to store the captured carbon for thousands of years, locking it away.
With science and technology, they harness what microorganisms have been doing for billions of years to help us tackle human-caused climate change, by adding them to agricultural fields during the growing season.
As the crops grow the microorganisms accelerate the mineralization of soil carbon, which then sinks when itโs rained on deep into the soil, making way for annual carbon removal. Read more about Andes.

We love questions! We want you to feel 100% comfortable and excited about joining our Carbon Removal Portfolio. It's something we wished existed but couldn't find, so we made it!
Carbon Dioxide Removal (CDR) is anything that pulls planet-heating carbon dixoide out of the air and stores it safely for a period of time. The longer the better.
It's a range of solutions that include various Nature-based, some tech-enabled or nature-inspired and fully engineered approaches and technologies. For example:
Forests and oceans are crucial natural carbon sinks which already draw down and lock away huge amounts of emissions. They'll be a part of the solution, but likely only about 20-30% of the removal we need.
On the more technological and engineered side, you might have heard about things like Direct Air Capture, Bio-oil, Biochar or Enhanced Weathering or Ocean Blue Carbon. These approaches, and others being worked on, are going to be need to fill the gap.
Go deeper into the different types of carbon removal.
Our CDR portfolio is a blend of different carbon removal solutions, mixed together to make it an affordable cost per tonne. Here's more info.
We believe this approach is ideal, based on the science-backed pathways to support growing the global carbon removal capacity to gigatonnes per year.
Combined with large scale global decarbonization, we need to reach about 10 billion tonnes of annual removal by 2050. There is no silver bullet solution and no one category or company will be big enough, which is why we take a portfolio approach to invest in a range of approaches.
Following the science-backed approach to Net Zero we advocate for 90% emissions reductions and decarbonization from current levels (about 50 gigatonnes of CO2e per year). Then using high permanence removals for the 10% hard-to-reduce remaining emissions.
Our angle on CDR is that even for that 10% it's a huge lift from where we are. Investing and growing the industry now is crucial.
If our goal is to build up the carbon removal industry to be the size we'll need by 2050 it needs to grow about 40%+ every year. It's not something that we can switch on overnight, it's something we'll have to build-up over time.
Not so much. Offsetting has been traditionally used to counterbalance the continued release of emissions, which only adds to the challenge of slowing and then reversing the increase in global average temperatures.
The vast majority (cough - 95% - cough) of offsets available don't remove carbon. Some may be good projects and have other societal benefits that aren't primarily about removing the gigatonnes of harmful gases we humans have pumped out.
Where carbon removal is different is that the only reason many of the technologies exist is to take out and sequester carbon dioxide - from the air or elsewhere - for hundreds to thousands of years, so it can't contribute to the continued heating of the planet and all the impacts of that.
Carbon removal is what's called highly additional, meaning the primary reason it exists is to do exactly as its name suggests.
This said, carbon removal can be used to offset emissions, though this should be only as part of a concerted effort to reduce as large a chunk of emissions as possible. It can also be used to remove older emissions that happened in the past.
We think that now is the time to fund and invest in carbon removal. Even if it is still more expensive than traditional offsets and it's not always viable to buy the same tonnes, it works in the way we need by literally removing the carbon dioxide so it can't contribute to climate change.
Find out more about Avoidance Offsets and the Voluntary Carbon Market.
There are a whole range of reasons. To us, some of the most compelling are:
- So the industry reaches about 10 billion tonnes of capacity by 2050 - the "net" bit of Net Zero
- The ratio of carbon removal in the Voluntary Carbon Markets needs to increase (compared to other approaches like avoidance or reduction)
- No one carbon removal type or company is going to be big enough on its own, we need a range of solutions and providers
- When combined with reducing emissions from everything we do, carbon removal will be a key tool to slow and then reverse climate change
- Funding and investing in it now helps to reduce the cost per tonne it takes to remove the carbon. Decreasing the cost by increasing demand will support the growth in supply of high-quality carbon removal options and capacity volume.
More on why we should invest in carbon removal now.
Our ready-made, curated, portfolio of high quality carbon dioxide removal (CDR) solutions is live. It aims for the highest permanence-for-the-$-per-tonne that we can find.
We're excited to be working with an inspiring group of global CDR companies taking the fight to the Climate Crisis. They're doing amazing work that holds a tonne - pun intended - of promise.
Have hope, make progress ๐
