# TRUE: The ozone layer is healing because countries phased out many CFC chemicals.

> Countries did phase out many CFCs through the Montreal Protocol, and public scientific assessments link those cuts to falling ozone-depleting chemicals and gradual ozone recovery. The ozone layer is improving, though full recovery is expected to take decades.

## Claim
The ozone layer is healing because countries phased out many CFC chemicals.

## Verdict
- Label: TRUE
- Source match: Strong
- Confidence: High
- Score: 95
- Meaning: The claim matches the public scientific consensus.

## Copy-Ready Comeback
FactPage check: TRUE. — the ozone layer is healing, and the phaseout of many CFCs under the Montreal Protocol is the main reason.

## Bottom Line
Countries did phase out many CFCs through the Montreal Protocol, and public scientific assessments link those cuts to falling ozone-depleting chemicals and gradual ozone recovery. The ozone layer is improving, though full recovery is expected to take decades.

## Evidence Lines
1. Global CFC phaseouts happened - The Montreal Protocol and its later amendments required countries to phase out production and consumption of major ozone-depleting substances, including many CFCs. That treaty is widely credited as the central policy fix
2. Ozone-depleting chemicals fell - Scientific assessments report that atmospheric levels of key ozone-depleting chlorine and bromine chemicals have declined after the controls. That is the mechanism expected to let stratospheric ozone rebuild.
3. Recovery is real but slow - UN and scientific assessments say the ozone layer is on track to recover over coming decades, with different recovery dates by region. It is healing, but it is not fully repaired yet.
