**Payment provider Stripe is inviting its clients to choose to donate a percentage
of their transaction income to fund projects that help tackle the climate crisis
by removing carbon. Launched in the US last October it has now been extended globally.**

Fundraising UK Ltd has already signed up to the programme. So every time you book
a training course with us or pay for our consultancy via Stripe, we’ll be donation
a small portion of that to Stripe’s climate partners.

Stripe will not take any fees for Stripe Climate contributions, and “will use 100%
of the funds to accelerate the development of carbon removal technologies”.

**Nan Ransohoff**, Head of Climate at Stripe, said:

> “Many of our users have told us they want to take climate action, but don’t because
> figuring out what to do can be time-intensive and complicated. Stripe Climate 
> makes it easy for businesses of any size to help tackle climate change by funding
> frontier carbon removal.”

Last year Stripe spent $1 million on carbon removal from companies offering some
of the most promising approaches, releasing the details of its purchase criteria
in an open-sourced [framework](https://github.com/stripe/negative-emissions-source-materials)
on Github.

The projects and organisations that [Stripe selected to benefit](https://stripe.com/gb/climate)
are CarbonCure, Charm Industrial, Climeworks, and Project Vesta, and more are being
lined up.

**CarbonCure** injects CO₂ into fresh concrete, where it mineralizes and is permanently
stored while improving the concrete’s compressive strength. Today they source waste
CO₂, but represent a promising platform technology for permanent CO₂ storage, a 
key component of future carbon removal systems.

**Climeworks** uses renewable geothermal energy and waste heat to capture CO₂ directly
from the air, concentrate it, and permanently sequester it underground in basaltic
rock formations with Carbfix. While it’s early in scaling, it’s permanent, easy 
to measure, and the capacity of this approach is theoretically nearly limitless.

**Charm Industrial** has created a novel process for preparing and injecting bio-
oil into geologic storage. Bio-oil is produced from biomass and maintains much of
the carbon that was captured naturally by the plants. By injecting it into secure
geologic storage, they’re making the carbon storage permanent.

**Project Vesta** captures CO₂ by using an abundant, naturally occurring mineral
called olivine. Ocean waves grind down the olivine, increasing its surface area.
As the olivine breaks down, it captures atmospheric CO₂ from within the ocean and
stabilises it as limestone on the seafloor.
