Introduction toClimeworks
High-quality carbon removal
services via Direct Air CaptureCarbon removal is needed to get to net zeroConfidential

Source: Adapted from IPCC (2022) & United Nations Environment Programme (2021)•

Based on all IPCC’s
scenarios, CO2
must be removed
from the air tokeep global warming
within 1.5°C.

•Corporates need toaccelerate emissions
reduction whilestarting to invest in
removals for yourresidualemissions.

2How our technology works

Phase 1

Confidential

Phase 2•

The air is drawn
with a fan into thecollector where theCO₂ is captured ona filter material.

•The collector isthen closed andthe temperature
increased up to 100°C to release theCO₂, to becollected forstorage.
