Developing integrated zero-carbon planning solutions


Cities and urban communities are the places where low-carbon transition is currently happening. South Wales Swansea, Cardiff and Newport are now the focus as these communities require large-scale sustainable city planning to help reshape their lives. Integrated urban programmes are essential but will require both public and private investment.

The key steps already taken include decarbonising the electricity systems, optimising energy use in buildings, providing cleaner and affordable alternatives to cars, and cutting waste while increasing recycling. This is a great start but we need to accelerate the programme if we are to hit the 2050 target.


Our aim is to establish an ‘optimum’ solution for South Wales by assessing the cost and impact of different levels of decarbonisation, illuminating system trade-offs and insights. We are gathering data from a huge range of sources on potential energy, cost and carbon savings from hundreds of low-carbon measures, taking into account changes in the economy and the wider energy infrastructure of the region.

Goodbye to greenhouse gases

Our ultimate aim is for our cities to have zero-carbon footprint. For them to become zero-carbon, we must commit to:

Collectively reducing emissions of greenhouse gases to zero and cease all practices that emit greenhouse gases

Ensure renewable energy supersedes other non-renewable energy sources and becomes the sole source of energy

Decarbonise electricity and move to zero-emission transport

We will use best-available projections to estimate savings emerging from different measures (energy, cost and carbon), future energy prices, and the rate of decarbonisation of the South Wales electricity grid.

We expect to conclude that to achieve the desired reduction of carbon emissions, ‘top down’ supply-driven strategies will be more deliverable than ‘bottom up’ demand-driven strategies.
