How can I vertically align a font-awesome input checkbox with its label?

I'm using font-awesome in place of default checkboxes and they are not vertically aligned with their labels. How can I either vertically align them or position the label without moving the checkbox itself?

HTML

<div class="row">
    <input type="checkbox" class="checkbox-green" id="authorized">
    <label for="authorized">I am authorized to work in the United States.</label>
</div>
<div class="row margin-top-12">
    <input type="checkbox" class="checkbox-green" id="drugs">
    <label for="drugs">I am not currently using illegal drugs.</label>
</div>
<div class="row margin-top-12">
    <input type="checkbox" class="checkbox-green" id="felony">
    <label for="felony">I have not been convicted of a felony.              </label>
</div>

CSS

@import url(//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css);

.checkbox-green { display: none; }

.checkbox-green + label:before {
  font-family: FontAwesome;
  font-size: 34px;
  width: 50px;
  color: $brand_green;
  display: inline-block;
  cursor: pointer;
  content: "\f096";
}
.checkbox-green:hover + label:before { color: $brand_green--dark; }
.checkbox-green:checked + label:before { content: "\f046"; }
