In March 2017, Beyond Nuclear conducted two workshops at the Green Nuclear-Free Wales conference for activists in Aberystwyth. The workshops were titled “Framing the anti-nuclear message using Welsh values.” We ran through some exercises together to reframe our messages using terms and imagery that we felt would resonate with the audiences we need to convince to oppose new nuclear build in Wales. We also identified messengers we thought would be most trusted by our target audiences. Finally, we discussed communication tools. This handbook was produced to reflect that work, to serve as a guide and to provide exercises for messaging and framing as the campaigns continue.
