# oecd.environment.emissions

Retrieve annual greenhouse gas (GHG) emissions data for any OECD country from the OECD Environment Policy and Progress indicators database. Returns CO2-equivalent emissions (in million tonnes) broken down by gas type (CO2, CH4, N2O, F-gases, etc.) and economic sector (energy, transport, agriculture, industry, waste, etc.). Covers OECD members from 1990 to the latest available year, with data aligned to IPCC inventory guidelines and UNFCCC reporting. Useful for climate policy analysis, carbon footprint comparisons, and tracking progress towards net-zero targets. Source: OECD ENV.EPI SDMX API, CC BY 4.0, no auth required, unlimited.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "oecd.environment.emissions",
    "arguments": {
      "country": "<country>"
    }
  }
}
```

## Why oecd.environment.emissions is rated Low

Tool retrieves public environmental statistics with no side effects or data modification capability.

From the tool's own definition: "Retrieve annual greenhouse gas emissions data for any OECD country"

## Use case

AI agents call oecd.environment.emissions to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "oecd.environment.emissions": {}
  }
}
```
