FAQs for act50
Your go-to resource for act50, renewable electricity sourcing, and Scope 2 reporting best practices.
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?
Regional & Market Differences
- What are the rules around buying EACs internationally?
- 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?
