No matter how efficient you are, unless you are completely off the grid you’re still going to have some sort of carbon footprint.
You can neutralize this carbon footprint using Carbon Offsets.
One carbon offset represents 1 metric ton reduction of greenhouse gas emissions.
If you emit 5 tons of greenhouse gas at your facility, you can invest in a project that sequesters 5 tons of greenhouse gas to offset the footprint created from your emissions.
