# Environment Variables Global environment variables to be passed down to all hooks and builds. If you have an environment variable named `FOOBAR` set to `on`, your `.goreleaser.yaml` file could use it like this: ```yaml # .goreleaser.yaml env: - FOO={{ .Env.FOOBAR }} - ENV_WITH_DEFAULT={{ if index .Env "ENV_WITH_DEFAULT" }}{{ .Env.ENV_WITH_DEFAULT }}{{ else }}default_value{{ end }} before: hooks: - go mod tidy builds: - binary: program ``` This way, both your before hooks (in this example, `go mod tidy`) and the underlying builds (using `go build`) will have `FOO` set to `on`. The root `env` section also accepts templates. !!! tip Learn more about the [name template engine](/customization/templates/).
