Electricity Supply & Contract Types

• How does purchasing EAC's compare to having a Virtual Power Purchase Agreement (VPPA)?
• If my supplier already provides renewable electricity with certificates, do I still need a platform for purchasing EACs?
• Does the renewable electricity we purchase physically reach our facilities, or is it tracked separately through GOs?
• If a supplier provides 100% renewable electricity, do companies still need REGOs and a market-based emissions factor for reporting?
• What are REGO-backed tariffs, and how can companies obtain evidence that REGOs have been retired on their behalf?
• Why can UK electricity suppliers offer green tariffs without providing REGOs, and how can companies obtain REGOs if the supplier doesn’t retire them?
• How can companies make smart investment decisions in solar, renewable electricity, and PPAs amid changing incentives and regulations?
• Can tenants claim renewable energy benefits when their landlord purchases and retires Guarantees of Origin?
• How should companies think about when to buy EACs, hedging considerations, and the difference between bundled and unbundled contracts?

EAC Pricing & Procurement

• How much do EACs typically cost?
• Do EAC prices vary by vintage year?
• Can EACs be purchased after electricity has been used, or do they need to be bought in advance?
• Is it more cost-effective to buy EACs separately rather than purchasing green electricity from a supplier?
• Is there an EAC price forecast available for the next fiscal year?
• Are EAC prices higher when purchased through the platform due to fees?
• If EAC prices rise and we stop buying them, will our emissions suddenly increase — and does that appear misleading?
• What is a reasonable cost per ton of CO₂ reduced across different decarbonization initiatives, and how should companies evaluate these options financially?

Scope 2 Basics & Reporting Rules

• If EACs only cover part of my electricity emissions, can I subtract that amount from my total market-based Scope 2 emissions?
• Are EACs a quick way to reduce reported Scope 2 emissions without changing electricity supply?
• If our energy bill shows a percentage of renewable electricity, why do we still need EACs?
• When is “green power” accepted as zero-carbon under standards like EN 15804 (EPD), the GHG Protocol, ISO 14064-1, and ISO 14067?
• If a supplier gives us a grid-mix breakdown, do we still need EACs to report renewable electricity?
• If we buy EACs but our physical electricity comes from another country, how is that reflected in Scope 2 reporting?
• Do EAC purchases reduce Scope 1 and Scope 3 emissions, or only Scope 2?
• If we buy enough EACs to cover all our energy use, can we report zero Scope 1 and Scope 2 emissions?
• How do companies calculate Scope 2 emissions when they generate their own solar electricity on-site?
• How can organizations show progress toward emissions-reduction targets while waiting for longer-term measures to take effect?
• Does REC/GO retirement start on the purchase date, or can certificates be applied to a specific reporting year?
• Do cloud services fall under Scope 2 or Scope 3, and how do AWS’s renewable energy purchases influence our emissions calculations?
• How should companies approach carbon credits under CSRD, and how is this different from using EACs for Scope 2?
• Do Scope 2 reductions achieved through EACs lead to real global CO₂ emission reductions?
• How should tenants account for emissions from shared building heating systems, and can Biomethane GOs be used to reduce them?
• How can companies reduce Scope 2 emissions if they don’t own or control their facilities?
• How should companies think about the sustainability of nuclear energy, given its low emissions but long-term waste challenges?
• How do you calculate Scope 2 emissions from a renewable PPA, and are emissions zero under both market-based and location-based methods?
• Does using 100% renewable electricity result in zero market-based Scope 2 emissions, and do renewable purchases need certificate verification?
• How should small companies with limited Scope 2 emissions approach reduction and reporting?
• How local do renewable energy certificates need to be for compliance with the Corporate Net-Zero Standard?
• How will proposed Scope 2 Guidance revisions affect RECs, and what should companies do to prepare?

• Can companies purchase renewable energy certificates for electricity use in Indonesia?
• Can companies purchase renewable electricity certificates for India?
• Why are Ukrainian GOs not visible on international tracking platforms?
• What credible strategies can companies use to show Scope 2 progress in regions with fossil-heavy grids and immature renewable markets?
• How do Scope 2 challenges differ across regions, and what is the situation in the UK?

Renewable Energy Certificates

• How can companies ensure their use of EACs is not considered greenwashing, and that certificates aren’t double-counted?
• Is it misleading to claim lower emissions when we buy EACs but still use grid electricity?
• Can EACs be used to reduce emissions from energy sources other than electricity?
• How can organizations verify how much of their electricity comes from renewable sources, and how are green energy certificates audited to prevent duplication?
• What makes a REC or EAC credible, and do they need to be sourced from RE100 suppliers?
• Do EACs apply to Scope 2 categories beyond electricity?
