We support the aim of seeking to maximise energy efficiency in developments, reduce carbon emissions and encourage use of renewable energy sources. We would comment that 'Inland waterways are supporting climate change, carbon reduction and environmental sustainability initiatives by:
* Assisting in the mitigation of flood risk
* Playing a role in urban cooling
* Providing sustainable transport
* Providing biodiversity and forming ecological corridors; and
* Contributing to regional and local renewable energy targets through onshore hydro electric power, and the use of canal water for heating and cooling buildings'

(TCPA Policy Advice Note: Inland Waterways: Unlocking the potential and securing the future of inland waterways through the planning system (2009)).

The role that waterways can play should be recognised and supported, and in particular PO12 could refer to consideration of utilising canal water for heating/cooling of buildings where practicable.
