EX-ACT Editions: "Standard" and "Tier One"

EX-ACT version 5 is released in the two editions “Standard” and “Tier One”. The “Standard” edition comprises the full functionality of EX-ACT. It allows users to either use Tier 1 or Tier 2 level of complexity, following the IPCC definition.

The edition “Tier One” is a simplified version that is reduced to the exclusive use of the Tier 1 level, not allowing for the specification of regional specific Tier 2 data. Since it is in all other aspects identical to the standard edition the accompanying material on this website applies to both editions of the tool.

* Intergovernmental Panel on Climate Change (IPCC)
