The UNISOT end-to-end Supply Chain connectivity provides unique access and visibility to verified Environmental Liability information from the complete value chain. Enabling an unprecedented ability to produce auditable Scope 1 accounting across corporate supply and distribution chains.

The foundation for future energy-efficiency and environmental improvements.

Providing services of an energy-efficient public blockchain that can manage high volume of data.

Gone are the days of ‘greenwashing’; customers can hold producers accountable.

The immutability of records ensures data is accurate, secure, verifiable, and resistant to manipulation.


The difficulty of tracking emissions from multiple suppliers and customers across multitier value chains makes it virtually impossible for a company to reliably estimate its Scope 3 numbers. The Scope 3 measurement is fatally flawed.

UNISOT’s E-liability Module (ELI) offers transparent GHG emissions tracking across business supply and distribution chains, refining the current system and reducing inaccuracies and manipulations. It replaces infeasible Scope 2 and Scope 3 measurements with arm’s-length and auditable Scope 1 transactions. This eliminates the current duplicative counting of emissions as well as reduces incentives for gaming and manipulation.

Measuring Corporate GHG Emissions

The GHG protocol identifies three types of Greenhouse Gas emissions and gives explicit guidance for measuring and reporting them:

Scope 1: Direct emissions from sources that are owned or controlled by a company, such as its production and transportation equipment.

Scope 2: Emissions at facilities that generate electricity bought and consumed by the company.

Scope 3: Emissions from upstream operations in a company’s supply chain and from downstream activities by the company’s customers and end-use consumers.


Each company in the supply chain measures its Scope 1 GHG emissions as “E-liabilities”, in units of emitted water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3).

Each company allocates its E-liabilities to individual products using standard cost-accounting (ABC) techniques. When a product is sold, the price includes not only the manufacturer’s price but also the product’s allocated E-liability. The E-liabilities records are secured and auditable in the public Blockchain.

The E-liability process continues until the consumer stage, where the consumer has access to the total E-liabilities generated in the product’s whole production and distribution cycle, as an addition to the current ingredients and nutrition label, i.e. the UNISOT Digital Product Passport. The consumer is now empowered to make purchasing decisions based on the product’s E-liability.
