Green Party leader Zack Polanski has called on Andy Burnham's government to publish in full an intelligence report warning that the collapse of overseas ecosystems would have catastrophic consequences for the United Kingdom's national security. Polanski said ministers must stop hiding the truth about the scale and impact of the climate and nature crisis, and challenged the prime minister to release an unredacted version of the report produced by the UK's spy chiefs.
The report, described as explosive, concludes that the degradation of ecosystems beyond the UK's borders carries direct and severe security implications at home. Polanski argued that the public has a right to see the full findings, and that withholding key sections prevents an honest debate about the risks the country faces. He framed the demand as a test of the government's willingness to be transparent about threats that intelligence agencies have already assessed as serious.
At the center of the dispute is the question of what the report actually says. According to Polanski, the document warns that the UK faces devastating security consequences as climate change and nature loss destabilize regions overseas. Those consequences could include disruptions to food and water supplies, mass displacement, and heightened geopolitical tension — all of which intelligence analysts treat as threats to national interests rather than distant environmental concerns.
Polanski's intervention places the ecosystem collapse report within a broader political argument about how governments handle scientific and security assessments that carry uncomfortable conclusions. By calling for full publication, the Green leader is pressing the case that environmental degradation is not a peripheral issue but a core matter of state security. He said the prime minister should come clean about the scale and impact of the crisis rather than allowing the public to remain uninformed.
The demand also reflects a growing push among environmental advocates to treat climate and nature policy as inseparable from defense and foreign policy. If overseas ecosystems fail, the effects do not stay contained within those regions. Supply chains, migration patterns, and international stability can all be affected, which is why the UK's spy agencies reportedly examined the issue in the first place.
For now, the government has not committed to releasing the unredacted report. Polanski's challenge keeps pressure on ministers to explain what portions of the assessment remain classified and why. The Green leader's position is that secrecy in this area serves no legitimate purpose and that voters deserve to understand the security risks that climate and nature loss pose to the country.
The episode highlights a widening gap between the urgency described in official assessments and the limited public information available about them. Polanski's call for full disclosure turns that gap into a direct political demand, one that asks the government to trust the public with the same warnings its own intelligence services have reportedly delivered.
