PRESS RELEASE: FOR IMMEDIATE RELEASE

5 July 2025

LONDON, UK - SustainabilityOf.Space today released the first comprehensive analysis behind the UK Space Leaderboard. This is the first regional report from a ground-breaking benchmarking tool that assesses sustainability performance across more than 500 space-related organisations operating in or from the UK.

Published ahead of the UK Space Conference (16^th and 17^th July 2025), the report reveals a growing but uneven commitment to sustainability in the space sector, with significant opportunities for improvement in space-specific environmental and social risk reporting.

Key Findings at a Glance

Progress Made:

19% of assessed organisations now publish formal sustainability disclosures, up from 13% in 2024
Gender-diverse leadership teams (21–40% women) are 9x more likely to report than male-only teams
Public companies report at nearly 9x the rate of private or government-owned entities (70% vs. 8%)

Critical Gaps Identified:

The vast majority of reports focus on terrestrial concerns, with space-specific environmental and social risks significantly underreported
Only 8.7% of environmental and Earth observation data companies report on their own ESG impacts, despite enabling others to do so
Only one of the top 10 performers is UK-headquartered, highlighting the international leadership driving sustainability in the space sector.

Methodology and Standards

The Space Leaderboard methodology draws on leading global standards (GRI, ISSB) and incorporates principles from the UK's Earth Space Sustainability Initiative (ESSI). The assessment evaluates operators, manufacturers, research institutes, launch service providers, analytics firms, and others across ten weighted metrics.

"Reporting, where undertaken, is dominated by terrestrial materiality assessments and risks, with little evidence of space-based harms assessments and transition planning," said Andrew Iwanoczko, Managing Director of SustainabilityOf.Space. "Some of this stems from current, early-stage standards development, however the actions of a few are very strong."

Looking Forward

The report underscores the critical importance of building on terrestrial frameworks while rapidly advancing space-specific reporting standards. Future editions of the Space Leaderboard will expand globally, with refined metrics encouraging transparency, gender-balanced leadership, and comprehensive disclosure of space-relevant harms and transitions.

This inaugural report establishes a baseline for measuring progress as the space industry evolves toward more sustainable practices and greater accountability.
