Report: Net-zero supports over a million UK workers

UK net zero sector now employs 1.1 million workers

The UK economy now supports around 1.1 million jobs linked to net zero businesses. Furthermore, the sector contributes £83.1 billion in gross value added, according to new analysis from the Energy and Climate Intelligence Unit. These figures suggest climate policy is moving from aspiration into measurable economic activity.

The sector grew by 10.1% between 2023 and 2024. This expansion reflects both direct employment in renewable energy, retrofitting, and related industries, and the wider supply chain effects that ripple through the economy. Consequently, the net zero transition is beginning to show up in jobs data, not just carbon reduction targets.

For UK businesses, especially those in manufacturing, construction, and professional services, this shift matters. Supply chains are changing. Procurement criteria increasingly favour suppliers with credible carbon reduction plans. Meanwhile, tender processes for public sector contracts now routinely include environmental standards as core requirements.

22,800 businesses now operate in the net zero economy

The ECIU report identifies 22,800 businesses working in the net zero economy as of December 2024. Of these, 3,850 grew by more than 10% in the previous year. This growth is distributed across renewable energy generation, energy efficiency services, low carbon transport, and building retrofits.

The employment figure breaks down into two distinct measures. The report calculates 951,000 full-time equivalent jobs when accounting for wider economic contributions. In contrast, the 1.1 million worker figure captures the broader employment base, including part-time roles and indirect positions supported through supply chains.

This distinction is important for businesses assessing market opportunities. Full-time equivalent counts measure core employment capacity in the sector. However, the wider worker figure reflects how net zero activity creates demand across adjacent industries, from component manufacturing to professional advisory services.

The ECIU analysis also estimates that every £1 generated by net zero businesses produces an additional £1.89 in the wider economy. This multiplier effect operates through supply chain purchases, employee spending, and business-to-business services. As a result, growth in renewable energy installation or building efficiency work creates demand for accountants, logistics providers, and materials suppliers.

Climate policy intersects with procurement and skills planning

The transition affects businesses in three distinct ways. First, public procurement now routinely includes carbon reduction criteria. Government buyers expect suppliers to demonstrate emissions measurement and reduction plans. Therefore, businesses without basic carbon accounting face exclusion from tender processes.

Second, supply chain requirements are changing. Large corporations increasingly require their suppliers to report Scope 3 emissions and set science-based reduction targets. This shift pushes environmental standards down through commercial relationships, affecting businesses that never considered themselves part of the climate sector.

Third, workforce planning needs to account for changing skill requirements. The Resolution Foundation identifies occupations representing 4.3 million workers as core green task jobs. These roles, spanning construction trades, engineering, and technical services, will require updated training and competencies as building standards, vehicle technologies, and industrial processes evolve.

The Climate Change Committee projects that the transition could create between 135,000 and 725,000 net new jobs by 2030, depending on policy implementation and investment conditions. This wide range reflects uncertainty about the pace of change. Nevertheless, the direction is clear across energy generation, transport electrification, and building efficiency work.

For small and medium businesses, this creates both opportunity and risk. Companies positioned to serve growing markets in heat pumps, EV charging infrastructure, or building retrofits may see sustained demand. Conversely, businesses without awareness of changing standards may find themselves unable to meet customer requirements or tender specifications.

What the data reveals about the UK transition

• The net zero economy now supports 1.1 million workers and contributes £83.1 billion in gross value added across the UK.
• The sector grew by 10.1% between 2023 and 2024, indicating sustained expansion beyond initial policy announcements.
• There are 22,800 businesses operating in the net zero economy, with 3,850 growing by more than 10% in the past year.
• Every £1 generated by net zero businesses creates an additional £1.89 in wider economic activity through supply chains and multiplier effects.
• The sector supports 951,000 full-time equivalent positions, while the broader employment base reaches 1.1 million when indirect roles are included.
• Core green task occupations affect approximately 4.3 million workers who will need updated skills as technologies and standards change.
• The Climate Change Committee estimates the transition could create 135,000 to 725,000 net new jobs by 2030 under favourable conditions.

How businesses should interpret these employment trends

The ECIU findings matter because they shift the net zero conversation from environmental obligation to commercial reality. Businesses face this transition regardless of their sustainability commitments. Market conditions, procurement requirements, and skills availability are changing in response to climate policy.

Companies should focus on three areas. First, understand what carbon reporting requirements apply to your business now and what may apply within the next three years. PPN 06/21 requirements for public sector suppliers remain in force. Additionally, larger customers increasingly impose their own environmental criteria on procurement.

Second, assess what skills your workforce will need as products, processes, and building standards evolve. This applies particularly to construction trades, facilities management, and technical services where installation and maintenance work is shifting toward heat pumps, EV infrastructure, and energy efficiency equipment.

Third, evaluate whether your supply chain can meet emerging requirements. If your business depends on contracts with large corporations or public sector buyers, you need visibility of their net zero commitments and supplier expectations. Many organizations now require annual carbon reporting from key suppliers.

The 10.1% annual growth rate in the net zero economy suggests this is not a temporary market fluctuation. Investment is flowing into renewable energy, building retrofits, and transport electrification. Consequently, businesses that develop relevant capabilities early will be better positioned than those waiting for regulatory mandates.

We work with businesses navigating these transitions through our net zero program for carbon reporting compliance and supply chain requirements. The focus is practical support for measurement, reduction planning, and demonstrating credible progress to customers and procurement teams.

The workforce dimension deserves particular attention. Skills gaps are already evident in heat pump installation, retrofit coordination, and energy assessment. Businesses that invest in training now will have capacity when demand increases. Moreover, those that can demonstrate competence in low carbon technologies will differentiate themselves in competitive tender processes.

Regional distribution of net zero employment varies significantly. Some areas have concentrations in offshore wind or battery manufacturing, while others focus on building retrofits or EV charging networks. Therefore, local labour market conditions affect recruitment, training availability, and business development opportunities.

Policy context and future trajectory

The ECIU report arrives as government industrial strategy explicitly links climate targets to economic growth. The net zero commitment is now embedded in planning policy, building regulations, and energy market design. This creates predictable demand for specific services and technologies.

However, policy certainty remains variable across different sectors. Renewable energy generation benefits from established support mechanisms and grid connection processes. In contrast, building retrofit policy has experienced multiple changes in grant structures and qualification criteria, creating uncertainty for installers and property owners.

The employment projections from the Climate Change Committee depend heavily on implementation conditions. The wide range between 135,000 and 725,000 potential jobs reflects different scenarios for investment levels, skills development, and regulatory clarity. Businesses planning workforce development need to monitor policy direction closely.

One clear trend is the increasing integration of environmental criteria into standard business processes. Carbon reporting, which was voluntary for most SMEs five years ago, is now routine for any business supplying public sector organizations or large corporate customers. Similarly, product specifications increasingly include embedded carbon data alongside traditional performance metrics.

For professional services firms, this creates sustained demand for carbon measurement, reduction planning, and supply chain advisory work. Accountants, consultants, and procurement specialists are adding environmental competencies to core service offerings. This pattern will likely continue as reporting requirements expand and customer expectations evolve.
