The Welsh Government has a unique policy to support One Planet Development. Here is how it works:

Through Technical Advice Note 6 (TAN 6) and Planning Policy Wales (PPW) it sets out land use planning policies to support sustainable communities, at present in a rural context.

Section 4 of TAN 6 defines One Planet Developments as applying Low Impact Development principles in the Welsh context and being exemplars of sustainable development. It stipulates the following characteristics of a ‘One Planet’ Community:

  1. Affordable housing for various sizes of household;
  2. Buildings that are at least Zero Carbon throughout their entire life-cycle;
  3. An initial ecological footprint of 2.4 global hectares per person or less and clear potential to move towards 1.88 global hectare;
  4. Carbon analysis;
  5. Close-to-zero waste;
  6. 100% renewable energy;
  7. Land-based enterprises to satisfy around 65% of the minimum needs of the occupants;
  8. Rainwater harvesting, both for fresh water drinking and for other purposes;
  9. Greywater and Blackwater ecological treatment with nutrient recovery;
  10. Provision to protect against extreme weather events such as flooding or drought;
  11. Low or zero carbon transport plan;
  12. An increase in biodiversity caused by the planting of more native species;
  13. Assessment of impact on the local community;
  14. Encouragement of the use of Welsh language and culture.
