The share of local authority municipal waste that was reused, recycled or composted each financial year, as measured for the statutory target.
The Welsh Government says wood recycling is likely to have been overstated in recent years, and Natural Resources Wales says the 2024-25 rate is likely to be at least 1 percentage point lower. The published figures can't be revised. The statutory target was 58% from 2015-16 and 64% from 2019-20, before 70% from 2024-25.
8 commitments in the Welsh Government's Programme for Government 2026 to 2030 fall under this brief, in the Programme's own words. Under each is how often it has been raised in the Seventh Senedd.
Demanding fairness from Westminster: Fair funding
Deliver a national programme to secure and restore disused tips, ensuring every tip is properly monitored, maintained, and managed. We will continue to insist that the UK government funds this work properly and in full.
Raised in 24 speeches. Most recently on 30 September 2026, by Niamh Salkeld. Matched on: “coal tips”.
Establish a Wales‑wide strategy on remediating contaminated land to map, prioritise and progressively restore post‑industrial land so communities are no longer exposed to derelict sites, toxic soils, and polluted waterways. We will continue to press the UK government to fund this restoration.
Ensure climate action and nature are prioritised and effectively coordinated across government, embedding decarbonisation, sustainability and environmental protection across all portfolios.
Take bold action to improve air quality, reduce waste and tackle pollution by keeping materials in use for longer, and ensuring the polluter pays as we transition to a circular economy.
Raised in 36 speeches, 1 agenda item, 10 written questions and 2 petitions. Most recently on 14 October 2026, by John Davies. Matched on: “polluter-pays”.
Apply a whole‑system, catchment‑based approach to improve water quality and strengthen climate and nature resilience in Wales. Our ambition is for every water body in Wales to be on a clear trajectory towards good status. Working in partnership across sectors, we will accelerate delivery of nature‑based solutions that reduce pollution and build resilience to future environmental pressures.
Raised in 42 speeches, 2 written questions and 1 petition. Most recently on 14 October 2026, by Llyr Gruffydd. Matched on: “water quality”.
Develop and implement a cross‑government Climate and Nature Action Plan for Wales, supported by a Climate and Nature Board. The plan will strengthen climate and nature resilience, enhance environmental sustainability, support a just transition and identify practical action towards a pathway to net zero by 2040. As part of the plan, we will set ambitious targets to achieve substantive nature recovery by 2050.
Governing responsibly
Work with our newly created Flood Forum for Wales to bring together local authorities, Natural Resources Wales, emergency services, and community organisations to coordinate national strategy on flooding.

30% of Welsh adults said climate change and policies to deal with it would be very important to their vote.

Written questions
4 written questions to the Welsh Government on this brief in the Seventh Senedd, 4 answered so far. The latest:
Water is a finite resource, a public health necessity, and a commodity. Yet current regulation is falling short, leading to rising pollution and higher bills.
Water companies hold a critical position in safeguarding both environmental and public health. Concern over the pollution of our waterways has been building, and as such, scrutiny of water company practices has become more stringent.
Water is an essential resource. Whilst our natural waters form important ecosystems and are integral to the environment, water also plays critical roles in applications as diverse as sanitation, industry, navigation and recreation.
