# env

The `env` step type stores environment variables for the steps that follow, letting one step in a custom command or workflow compute values that later steps consume.

```yaml
steps:
  - name: set_region
    type: env
    vars:
      AWS_REGION: us-east-2

  - type: shell
    command: echo "$AWS_REGION"
```

## Fields

- **`vars`**
  Required. Map of environment variable names to values. Values support templates.

This step type is different from the step-level [`env`](/workflows/steps/env) field, which applies environment variables only to the current step.
