Why do companies procure Spain GOs?
Spanish Guarantees of Origin enable credible renewable electricity claims within Spain for
compliance purposes. These GOs are used to:
Report Scope 2 emissions (market-based)
Required or recommended under GHG Protocol, CDP, RE100, SBTi, and equivalent frameworks.
Without GOs, companies must report using Spain's residual mix carbon intensity,
currently
0.2922 tCO₂/MWh
.
Meet investor and lender ESG requirements
Satisfy the renewable criteria that institutional investors and sustainability funds
require, unlocking superior financing terms.
Back sustainability and product claims
Support your clean electricity claims with verifiable, registry-cancelled, audit-ready
certificates for emissions reporting.
Support new renewable buildout
Direct capital to our network of member producers through certificate revenue, improving
the economics of renewable projects.

Spain is one of Europe's biggest GO markets, driven by strong solar generation, and procurement desks regularly look to Spain when building certificate positions. We built Soldera to help companies tap into markets like Spain's with confidence and full traceability. Our platform removes the complexity from GO procurement so businesses can focus on sustainability rather than admin.

Spain is often one piece of a larger European GO portfolio, and managing CNMC separately from every other registry wastes time. Soldera automates Spanish GO procurement end to end, from sourcing to retirement, matching you with verified producers at transparent prices.
