Moving towards being a One Planet City

Cardiff is growing fast – and we’re committed to making sure that Cardiff grows in a sustainable way that protects the quality of life for current and future residents – as well as ensuring we protect the environment.

Here’s just a sample of some of the great things the council is doing to become a ‘One Planet City’

Greener Grangetown

The £2m Greener Grangetown initiative is a new approach to managing rainwater and is the first scheme of its kind in the UK. We’re working in partnership with Dwr Cymru Welsh Water and Natural Resources Wales, on this scheme is aimed at the better management of rainwater in the community, using new techniques to catch, clean and divert rain water directly into the River Taff.

Water is currently pumped 6 miles away through the Vale of Glamorgan and into the sea. This scheme will significantly reduce our carbon footprint and the cost of pumping the water away. Check out this video to find out what it’s all about!

If you would like to know more about the scheme, or to share your views and shape the proposed designs, public events will take place on the following dates:

  • Wednesday 10th June, 4-8pm, Salvation Army Hall on Corporation Road

Work begins on Radyr Weir Hydro-Electric scheme

Next week sees work start on a new £2.7 million project to harness the energy-producing power of the River Taff. Water will be channelled through two ‘Archimedes’ turbines which will generate enough sustainable electricity to power 550 homes – as well as providing the Council with around £140,000 in income each year.


This is another exciting project that will help support the city’s drive to boost its green credentials, with other planned projects including a solar farm at Lamby Way, which will help reduce our reliance on non-renewable forms of energy.

Street Lights go white!

You may have noticed in the recent months that the colour of street lighting has changed.  This is because the city has been swapping traditional yellow bulbs in their lamps for new energy saving, white bulbs or ‘Street Wise’ lamps as they are known.

Currently, we use 70 watt bulbs to light lamps in our streets. This will be cut to 50 watts and dimmed from Midnight to 6am which was one of the ideas that you (the residents of Cardiff), put forward in the Cardiff Debate.

You don’t have to be concerned about the amount of light emitted from these lower wattage bulbs, as the ‘Street Wise’ bulbs are actually brighter than the traditional yellow bulbs and far more energy efficient. Once the 24,000 ‘Street Wise’ lamps are installed across the streets of Cardiff there will be an energy saving of up to 35%. This should also bring financial savings of around £340,000 per year for the Council by 2016.

Pollinator Project

One of the reasons Cardiff  is one of the best cities to live in Europe, is down to the fact that our city has more green space per person than any major UK city.

A new Pollinator Project will see Cardiff’s parks and green spaces encourage biodiversity In order to protect our natural environment.

Sixteen locations, which are already home to some interesting wildflower species, have been chosen for a new annual mowing regime which will in time transform them into colourful wildlife havens.  It is hoped that this will help reverse the decline in pollinators, such as butterflies and bees, and gradually result in habitats rich in wildlife.  Pollinators are vital to creating and maintaining habitats and ecosystems.

Paths and edges will continue to be mown regularly in these parks in order to ensure a good contrast with the longer grass and plenty of space will remain available for a picnic or a kick around!

This initiative is one of a number of great projects going on in the city such as the Giving Nature a Home project with RSPB Cymru, which has seen school children ‘re-wilding’ wellies in order to attract and provide a home for bees and butterflies!
