If the UK is to meet its target of net zero emissions by 2050, then human behaviours will have to change. The Knowledge Transfer Network (KTN) is working with ENGIE to identify innovative solutions that will help to instigate, facilitate and sustain these changes. Behavioural change is required at both an individual and organisational level and ENGIE is interested in solutions that seek to change behaviour in ways that support the rapid transition to zero carbon. ENGIE is committed to be the global leader in the zero carbon transition and has a strong track record of deploying innovative, low carbon solutions across the Energy, Services and Regeneration sectors. Through this challenge ENGIE is looking to identify UK SMEs that it will invite to apply for funding under Round 4 of the ENGIE UKRI Clean Growth Innovation Fund. Only companies that are successful under this KTN iX challenge will be eligible for funding under Round 4.
