Committing to the Zero Debris Charter

Satellites in orbit underpin our modern lives. But swirling fragments of past space endeavours are trapped in orbit around Earth, threatening our future in space in sharply increasing numbers.

The Zero Debris Charter represents a collaborative effort within the global space community, serving as foundational document and initiative. This community-driven charter covers overarching guiding principles and jointly defined targets to get to Zero Debris by 2030.

Facilitated by ESA’s ‘Protection of Space Assets’ Accelerator and co-developed by 40+ space actors, the Zero Debris Charter was published on 7 November 2023.

It is open for signatures by all entities dreaming of and committing to a Zero Debris future by 2030. Many have already registered their commitment and support, as demonstrated by the list of supporters below.

ESA is committed to a profound internal transformation of its space debris mitigation and remediation practices through the ESA Zero Debris approach. The Agency aims to stimulate similar endeavours in Europe and beyond, including supporting the Zero Debris Charter and its community.

SPAICE Technology Ltd

Spaice is developing a robotic kit to enable players in the satellite industry to access in-orbit services and debris removal at scale for any satellite. By signing the charter, Spaice reaffirms its mission to achieve self-sustaining orbits through a generalizable technology that utilizes AI. This technology can identify any satellite, autonomously navigate to it, and perform robotic operations to extend its life or ensure its proper disposal, thereby contributing to the safety of orbits.

Sustain Space Ltd

Sustain Space will be signing the Charter, as we see this as a cornerstone of the future of sustainable operations in space. Our vision is to create a space industry that can be proud of its sustainable credentials and the Zero Debris Charter is the banner under which we can all congregate. We look forward to working with ESA and the wider community toward the shared goals of sustainability in space.

Sybilla Technologies

Sybilla Technologies mission is to support space exploration and Zero Debris Charter is an important step in the direction of long term, sustainable, fair, and safe usage of space. Earth's orbit is a limited resource which cannot become a threat or bottleneck for the human and robotic spaceflight. Transparent, ambitious rules and goals are needed not only to guide the growing space traffic but also to spur new industries and ideas on how to limit, remove waste, increase recycling and fair competitiveness.


TelePIX is committed to upholding the principles outlined in the Zero Debris Charter, aligning with its central role in fostering a Net Zero Carbon and Debris policy outcome to enhance space sustainability.

ThinkTank Maths Limited

ThinkTank Maths Limited develops Space apps and models for greater precision in Space Traffic Coordination (STC) and Space Situation Awareness (SSA). Our Precision Space apps and models are relevant to collision-avoidance, safe removal and re-servicing of satellites in line with ESA’s Zero Debris Charter. We strive to take 'space maths' a few steps further to contribute to a safe, secure and sustainable development of Space. Many of the models and calculations currently performed are outdated and have their limits when it comes to dealing with an increasingly crowded near-Earth Space forecast to exceed +70,000 satellites in the next 5 years.


This initiative aligns with our core values of responsible space utilization and preservation. We are committed to contribute with our technologies to enhance in-orbit servicing, active debris removal and Space Situational Awareness services. Also our new VLEO satellite will avoid further accumulation of space debris. We are glad to join forces with ESA and the other partners to promote the safe and sustainable use of space to preserve the benefits of space for future generations.
