Welsh Public Sector Unlikely to Meet 2030 Net Zero Target

Wales’ public sector is highly unlikely to achieve its ambition of reaching net zero carbon emissions by 2030, with financial pressures, skills shortages and a lack of coordinated action slowing progress, according to findings from Audit Wales.

The assessment raises significant questions about the ability of public bodies to deliver on the Welsh Government’s climate commitments, with decarbonisation increasingly competing against other spending priorities.

The Welsh Government declared a climate emergency in 2019 and established a collective ambition for the public sector to achieve net zero carbon emissions by 2030, positioning public organisations as leaders in Wales’ wider transition to a low-carbon economy.

However, the latest findings suggest that while the ambition has encouraged action, progress has been insufficient and significant barriers remain.

Audit Wales found that decarbonisation has become a lower priority for some public bodies as financial pressures intensify. Climate considerations have not been fully embedded into everyday decision-making, while opportunities for public organisations to work together on reducing emissions are not being sufficiently developed.

The report also raises concerns about the clarity of the 2030 ambition itself, which has been criticised as unachievable. Public bodies have called for greater practical support to turn strategic commitments into deliverable programmes, while the Welsh Government is not consistently checking whether organisations are meeting their stated milestones.

One of the most significant challenges is the potential cost of decarbonising public infrastructure.

It has been estimated that decarbonising Welsh council buildings alone would cost at least £2.3 billion, highlighting the scale of investment required at a time when public finances remain under considerable pressure.

Despite the financial implications, Audit Wales found that public bodies have made limited progress in understanding the short- and long-term costs of achieving net zero. Where longer-term estimates have been developed, some organisations have described the costs as unaffordable.

The findings also identify weaknesses in the way carbon emissions are measured and reported.

Although more public bodies are participating in the Welsh Government’s emissions reporting system, and previous gaps in information have been addressed, concerns remain about data quality, particularly emissions associated with supply chains.

Reported emissions have increased, although Audit Wales cautioned that improvements in reporting coverage have contributed to this trend, meaning the figures do not necessarily provide a complete picture of underlying performance.

Workforce capability represents another obstacle. Public bodies have identified shortages in the specialist skills required to plan and deliver decarbonisation programmes but often lack a comprehensive understanding of their future requirements. Many continue to depend on external expertise.

Ann-Marie Harkin, Executive Director for Audit Delivery, said:

“The collective ambition was about the public sector leading by example and being a catalyst for wider changes in the economy and society. We can list positive examples, but not enough progress has been made overall, and we owe it to future generations to do better.

“There are big questions around future spending and how that is prioritised when public sector decarbonisation is only one part of what’s needed to respond to climate change. Also, around how bodies secure the skills and capacity they need to rise to the challenge. And more work is needed to make sure that the way carbon emissions are reported is as accurate as possible. Wales is not alone in facing these issues but must play its full part.”

The findings have wider implications for the Welsh economy, particularly businesses operating in construction, energy efficiency, renewable energy and environmental services.

Decarbonising public buildings and infrastructure represents a potentially significant pipeline of work for Welsh suppliers, but uncertainty around funding, delivery timescales and investment priorities could make it harder for businesses to plan and develop the capacity needed to support the transition.

The report also highlights the importance of developing the specialist workforce required to deliver low-carbon infrastructure, energy management and emissions reduction programmes across the public sector.

Audit Wales has made recommendations focused on strengthening the Welsh Government’s leadership role, including clarifying the strategic direction, improving emissions reporting and providing greater support for financial planning.

Public bodies are also being encouraged to assess their own progress against a checklist included in the report.

With just four years remaining until the 2030 deadline, the findings suggest that achieving meaningful progress will require a stronger focus on delivery, more realistic financial planning and closer collaboration between government, public bodies and the businesses capable of supporting Wales’ transition to a low-carbon economy.
