### Research Objective
- Examine the international diffusion of carbon pricing policies.
- Quantify the global benefits of policy diffusion in terms of greenhouse gas emission reductions outside the adopting country.

### Data and Methods
- Combine a large international dataset on carbon pricing with several other datasets.
- For causal identification, estimate semi-parametric Cox proportional hazard models.

### Key Findings
- There is robust and statistically significant evidence for policy diffusion: adoption of carbon pricing in one country helps explain subsequent adoption of the same policy in other countries.
- Policy diffusion leads to quantifiable global benefits in terms of greenhouse gas emission reductions elsewhere.

### Thematic Subjects and Keywords
- Subject: Carbon tax, Climate policy, Environment, Greenhouse gas emissions, Taxes
- Keywords: Carbon tax, climate change mitigation policy, Climate policy, Global, Greenhouse gas emissions, North America, policy adoption, policy diffusion, pricing policy, small country, South America

### Practical Implications and Policy Relevance
- International diffusion of carbon pricing policies amplifies global mitigation outcomes through spillovers in policy adoption.
- Empirical evidence of diffusion supports policy coordination and information-sharing efforts to accelerate adoption of carbon pricing worldwide.
