Deep Sky & Lufthansa’s Carbon Removal Credit Partnership

Deep Sky builds, owns and operates infrastructure that can aid in reversing climate change and reducing global warming effects.

The company has entered into an offtake agreement with Lufthansa Group to provide high-quality direct air capture (DAC) carbon removal credits.

The aim is to reduce emissions and increase carbon capture and climate protection.

High-quality carbon removal

According to Deep Sky, the demand for CO₂ removal is skyrocketing however supply can’t keep up.

DAC technologies are expected to play a key role when it comes to achieving climate targets, especially in hard-to-abate sectors like aviation.

Deep Sky’s model is designed around delivering verifiable, durable carbon removal by securing critical inputs such as land, clean power, government support, DAC technologies and permanent geologic storage.

Its credits are positioned as a high-standard solution defined by strong quality controls, including direct removal from the atmosphere, rigorous validation and issuance through carbon registries and permanent storage with full traceability of CO₂ molecules. 

"Working with the Lufthansa Group on accelerating direct air capture credits for aviation reflects growing market momentum and the increasing importance of quality, credibility and delivery in carbon removal," says Guillaume Devaux, Vice President, Strategic Partnerships at Deep Sky. 

"We're seeing first-hand how the aviation sector is increasingly integrating carbon removal into its decarbonisation efforts and broader sustainability strategies."

By running a vertically integrated approach across capture, storage and energy supply, the company aims to reduce delivery risk while improving certainty and scalability. 

At the same time, it can help with cost reductions by deploying a technology-diverse portfolio of DAC solutions, positioning its carbon removal credits as both low-risk and designed for long-term affordability and reliability in blended carbon portfolios.

Collaborating for the climate

By supporting DAC technologies early, Lufthansa is contributing to its market development and future scalability.

The company is aiming to aid in advancing development as well as promoting and utilising innovative technologies.

The Lufthansa Group is already working with Airbus and Climeworks, as well as Deep Sky, to advance its climate protection portfolio.

Deep Sky has also collaborated with Microsoft and the Royal Bank of Canada.

Microsoft has purchased credits from Deep Sky in order to gain access to its portfolio and advance multiple DAC technologies at the same time.

"Quality is the single most important factor in the voluntary carbon market today," says Adrian Wons, Chief Executive Officer and Founder of Senken.

"We are pleased to have supported this deal, facilitating a collaboration between the Lufthansa Group and Deep Sky following a rigorous assessment of the project's technological and environmental integrity." 

With more than US$130m in funding, Deep Sky is backed by Investissement Québec, Brightspark Ventures, Whitecap Venture Partners, OMERS Ventures, BDC Climate Fund, BMO, National Bank of Canada, Breakthrough Energy Catalyst and many more.

Lufthansa’s climate protection portfolio

Lufthansa Group has restructured its climate protection portfolio with a stronger focus on technology-based solutions, integrating both emissions avoidance and long-term carbon removal into its broader strategy for more sustainable flying. 

Through its passenger-facing offerings, the company enables contributions to certified climate protection projects, with a diversified portfolio of 14 initiatives that are aligned with the UN Sustainable Development Goals. 

A growing share of these projects, now around 20%, focuses on permanent CO₂ removal from the atmosphere, reflecting an increased emphasis on scalable, durable climate solutions. 

“Climate protection projects, which complement our own emission reduction measures, are an important building block on the path to more sustainable aviation and the achievement of our climate goals,” says Nina Sproedt, Head of Sustainability at Lufthansa Group.

“With our carefully curated portfolio, we are increasingly focusing on technology-based projects that enable long-term CO₂ sequestration. 

“In this way, we are contributing to the further development and scaling of these technologies. 

“We offer our passengers the opportunity to support high-quality climate protection projects and the use of Sustainable Aviation Fuel, thereby actively participating in the transformation of aviation.” 

These initiatives span multiple regions including Europe and beyond and in 2025 alone, passengers contributed to projects addressing more than 710,000 tonnes of CO₂.

To deliver this portfolio, Lufthansa Group collaborates with a range of established climate and carbon management partners, including myclimate, First Climate, Ceezer, Senken, Climeworks and 1PointFive. 

The portfolio is split between avoidance projects, such as clean cooking and renewable energy solutions and removal projects, which include nature-based approaches like reforestation as well as technology-driven methods such as biochar and direct air carbon capture and storage (DACCS). 

Particularly advanced DACCS technologies are increasingly central to the strategy, enabling CO₂ to be captured from ambient air and stored permanently underground, marking a shift toward more durable and verifiable carbon removal solutions within the aviation sector.
