EST’s work with Carbon Trust
• Peer review
• Share EST wind
data – validation
• Explore hosting tool
f domestic
for
d
ti use
• Add value to EST
advice network
Added value for consumers
• Independent, trusted, authoritative
• Evidence based
• Local advice network
• Act On CO2 national helpline
• Consumer microgen website (in
development – to launch by March ’09)
Dissemination Strategy
• Work with advisory group and key stakeholders =
coordinated approach & minimise risk of bad news story
• Agree positive key messaging
• Develop supporting materials & tools (case studies,
updated
