Philip Charles on cut ting emissions

Circular economy has a key role to play in reducing UK carbon emissions

INFRASTRUCTURE PROJECTS ACCOUNT FOR 16% OF THE UK’S CARBON EMISSIONS, WHICH IS WHY CONSTRUCTION NEEDS TO APPLY A CIRCULAR ECONOMY FOCUS TO PROJECTS, SAYS PHILIP CHARLES

Circular strategies could cut infrastructure emissions by 50%

As the country begins its journey to recover

from the covid-19 pandemic, the prime minister’s urgent call to build back better, greener and faster is expected to accelerate project delivery. As we emerge from the global outbreak, we must also work towards reducing greenhouse emissions in line with achieving net zero carbon emissions by 2050.

Infrastructure accounts for 16% of the UK’s total carbon emissions and has influence over a further 37% which is attributable to the materials and energy required to build, maintain and operate projects. The Major Infrastructure – Resource Optimisation Group (MI-ROG), of which Aecom is a convener, believes it is imperative that a circular economy focus is applied to the planning and delivery of infrastructure projects to make sure the amount of carbon that is produced is limited.

While deploying new materials will be unavoidable at times, implementing circular approaches in line with net zero goals during the early stages of the design process can help the UK infrastructure sector reduce carbon emissions by up to 50% as well as cut costs and support a more resilient supply chain.

The UK government’s Infrastructure Carbon Review (ICR) explores various ways the industry can reduce carbon emissions when designing and delivering infrastructure projects. According to the latest MI-ROG white paper, circular economy approaches can be applied to the ICR themes as illustrated below: l Build nothing – challenging the need for new infrastructure and exploring alternatives. l Build less – maximising the use of existing assets through optimised operation and management. l Build clever – designing and implementing low-carbon materials, streamlining delivery processes and resource efficiency. l Build efficiently – embracing innovation and eliminating waste.

In order to accelerate this idea and make sure infrastructure owners and operators have the knowledge and tools to reduce carbon emissions in line with net zero goals, new business models are required. This includes a shift from product to service business models while embracing new low-carbon materials, digital design and modular construction as well as facilitating delivery of innovation.

It is imperative to gather relevant baseline data and set ambitious yet achievable targets, which will amplify the need to execute a successful circular economy approach. Compiling data on material use, recycled content and embodied carbon from pilot projects can be used as a tool to measure performance and identify further opportunities for carbon reductions.

For this idea to successfully develop and achieve maximum benefits, collaboration is key, particularly across the infrastructure sector as this will influence future policy and standards. ●

Exemplar competence in the electrical sector

Dame Judith Hackitt praised the ECS for its high standards. Phil Wilbraham explains its plans

Dame Judith Hackitt identified the Electrotechnical Certification Scheme (ECS) as an exemplar in her Independent Review of Building Regulations and Fire Safety. The scheme, covering more than 175,000 electrotechnical operatives in electrical, fire, emergency and security systems, network infrastructure and allied trades, has a long history of high standards, working hard to formalise training and qualifications for the sector, to keep the workforce competent, safe and healthy.

Its work complements that of the Competence Steering and Working Groups set up in the wake of the Grenfell Tower disaster in 2017. Since then, members of the ECS steering committee have been feeding into this process through Working Group 2 for Installers.

The focus now is on raising standards further. Recommendations on how to improve standards in the industry from Working Group 2 include setting minimum qualifications for each sector. These include a Level 2 or 3 diploma, CSCS or partner scheme cards, certification of the business, greater continuing professional development (CPD) and knowledge of fire safety in buildings.

ECS registered electrician status was introduced in 2017 to raise standards and recognise those qualified electricians who keep up to date with the latest edition of the Wiring Regulations and commit to an ongoing programme of CPD. The ECS steering committee is supportive of this move to raise the bar further through the Competence Steering Groups, as well as introducing new digital technologies to make the processes of identifying competence easier than ever before.

An expansion of the online ECS Employer Portal, used by almost 3,000 electrical contractors, ECS Check for Clients and the Supply Chain provides some of the industry’s largest clients and contractors with visibility throughout the supply chain. Digital solutions like this help everyone to recognise the importance of competency and make identifying qualifications, skills and training simple through the use of a real-time system and a downloadable app for use on site.

Further work will focus on introducing greater support for storing CPD, more flexibility on health, safety and environmental assessments and greater industry collaboration between the trades to ensure no one is left behind.

Phil Wilbraham is chair of the Electrotechnical Certification Scheme steering group.
