The UPS Carbon Neutral shipping label indicates that UPS customers have offset the climate impact of the GHG emissions produced by the transportation of that shipment. UPS calculates the emissions and purchases carbon offset credits equivalent to the GHG emissions created in shipping the package to make it "carbon neutral".

GHG emissions are tracked using the Carbon Neutral Protocol - a global standard for ensuring the integrity and quality of carbon neutral certification programmes and enabling businesses to be certified as CarbonNeutral.

Accredited carbon offset providers are used.

UPS customers can access this label by one of two means:

1. Contractual - whereby UPS measures customers' shipping-carbon footprint for a set period of time and transactions and offsets are then bought; OR

2. Per-Transaction or Package - where an offset can be bought for one particular shipment.

Extending its commitment to sustainability, UPS is currently matching the offset purchases, effectively doubling the offsets purchased in 2011 up to $1 million.
