Server-side is your best option, using PHP in this case. What I'll be doing is storing the data in a variable and sending it to another PHP page which recieves the variable contents. It's fairly simple.
Give your carbon td a "name" attribute:
Now before we go into the next part, I'm assuming you are using a form outside your table:
<td class="carbon" name="carbonData">4544 tons / 2285 tons</td>
The above button in red will send you to your result page.
<form action="newpage.php" method="post">
<td class="total_label">Your Totals</td>
<td class="money"> $-21850.00 / $385.53 </td>
<td class="time"> 0 hrs / 0 hrs</td>
<td class="carbon">4544 tons / 2285 tons</td>
<input type="submit" value="Go to page">
When you go to your result page (in this case newpage.php), make these adjustments:
Hopefully this helps
$dat = $_POST["carbonData"];
