Version history
Combined the calculations for several types of devices
Some devices were grouped together and assumed to have the same impacts.
August 2023
V1.1 to V1.2
Added equations for calculation GHG reductions
Increased transparency.
April 2024
V1.2 to V2.0
Aligned terminology with ISO 14064-2:2019
Improved consistency with the voluntary carbon market. LCA principles still apply.
April 2024
V1.2 to V2.0
Added risk assessment template for environmental and social do no harm
Provide more detailed and prescriptive assessment framework, clearer instructions for project developers.
April 2024
V1.2 to V2.0
Removed text for sections that are the same for all methodologies:
Measurability
Real
Technology readiness level
Minimum impact
Independently verified
Repeated text from the Standard Rules.
April 2024
V1.2 to V2.0
Added Monitoring Plan section
Alignment with Riverse Standard Rules V6.
April 2024
V1.2 to V2.0
Remove Rebound Effect and Independently Validated criteria
Alignment with Riverse Standard Rules V6.
April 2024
V1.2 to V2.0
Added uncertainty assessment section
Alignment with Riverse Standard Rules V6.
April 2024
V1.2 to V2.0
Include fraction of refurbished devices already on the market in the baseline scenario of GHG reduction quantification
Alignment with Riverse Standard Rules V6 and increase conservativeness.
April 2024
V1.2 to V2.0
Assign input used devices a fraction of environmental impacts from their first life, allocated based on their residual value
Input used devices are no longer considered waste. A more conservative assumption was made.
April 2024
V1.2 to V2.0
E-waste treatment in the baseline scenario is modeled as a mix of e-waste incineration and landfill, rather than the ecoinvent process for device waste treatment. The latter is now used to model e-waste recycling (see Appendix 1 for ecoinvent activity names)
More accurate and representative of e-waste treatment practices.
April 2024
V1.2 to V2.0
Country WEEE rates come from data for only small IT and telecommunications devices, instead of all WEEE.
Improved precision, because statistics for all WEEE covered devices such as household appliances, lamps, photovoltaic panels.
April 2024
V1.2 to V2.0
Multiple WEEE rates from different countries are selected based on the source countries of collected devices.
Improved accuracy. Previously, only one source country could be selected in the calculation model.
April 2024
V1.2 to V2.0
New device emission factors from ecoinvent were updated (see Appendix 1):
Smartphone: completely revised, see Appendix 5
Tablet, laptop: removed power adapter production, power adapter waste treatment, and the device waste treatment
PC: removed device waste treatment
Improved accuracy and harmonization of system boundaries.
April 2024
V1.2 to V2.0
Added additionality section
Alignment with Riverse Standard Rules V6.
May 2024
V2.0 PC to V2.0
Replace number of devices collected for number of devices sold as main input data, from which other values are calculated
Devices sold are easier and more reliable to track for Project Developers
August 2024
V2.0 to V2.1
Change USA, China and Turkey e-waste recycling rates in Appendix 4
Previous rates were erroneously calculated.
October 2024
V2.1 to V2.2
Create project scope requirements
Specify that operations in different countries must be registered as separate projects
October 2024
V2.1 to V2.2
Add minimum list of ESDNH risks
Align with Standard Rules V6.2
October 2024
V2.1 to V2.2
Specify minimum frequency of updating baseline scenario
Clarity and transparency
October 2024
V2.1 to V2.2
Update desktop PC new and refurbished emission factors in Table 3
Typo in the values in the table, didn't match the values used in the model
May 2025
V2.2 to V2.3
Change GHG quantification from ecoinvent v3.10 to v3.11
Using more recent data
May 2025
V2.2 to V2.3
