Introduction

Viridian is the EAC & EUA exchange, operated by AFS Energy BV. AFS Energy BV is a leading solution provider in the sustainability and renewable energy market, helping energy producers, utility traders, and corporate clients contribute to a zero-emission environment.

The Viridian platform serves as an energy transition hub — a marketplace where organisations can buy and sell sustainability instruments, including European Union Allowances (EUAs) under the EU Emissions Trading System (EU ETS), with real-time pricing and execution support from AFS Energy BV’s Sustainability Advisors.

What Viridian Offers

Through the Viridian Integration API, authorised third-party systems can connect programmatically to the Viridian Client Portal to submit and manage trade interest. The API provides:

  • Submit buy or sell interest for EU ETS allowances (EUAs) in real time
  • Receive firm, priced offers delivered directly to your system via webhook
  • Accept or reject offers within a defined time window
  • Track the full lifecycle of every integration request

When a request is submitted, AFS Energy BV prices it in real time and returns a firm offer. Your system then has a short window to accept or reject.

Custom integration arrangements — including bespoke workflows or extended functionality — can be arranged on request based on cost & expected volumes.

Current Scope

The API currently supports one product category:

  • EU ETS — European Union Allowances (EUAs)

EAC (Energy Attribute Certificate) trading is not yet available through the API but is on the product roadmap.

Who Is This For?

The Integration API is designed for developers and technical teams at client companies that are already onboarded onto the Viridian platform or liquidity providers that wish to automate their trading workflows.

Access is provisioned by AFS Energy BV on request.
