All carbon offsets sourced and retired by Offset Alliance meet the highest global standards for quality–proving to be additional, quantifiable, real, permanent and socially beneficial. Offsets are all developed, audited and third-party verified using the most trusted carbon measurement and reduction protocols from:

Carbon Offsets Vintage

All carbon offsets used to offset your business emissions have a vintage of six years or less relative to your business’s measured / offset year. We always make best effort to source and retire carbon offsets with a vintage year as close to your measured / offset year as possible. For example, your measured / offset year is 2019, the vintage will be 2014 or newer.

Carbon Offsets Retirement

All carbon offsets retired as part of your emissions offset are recorded in their respective public registry, including your business name for reference.

Vintage Explained

Carbon offsets are generated by a project after completing third-party verification of performing in accordance with the published protocol it is developed under. For example, a reforestation project starts Jan 1, 2013 and is then verified in early 2015. The credits generated by this project will have a vintage of 2013 and 2014, the years in which the emissions reductions occurred.
