Environmental Product Declarations offer facts for environmental and climate protection The building sector is responsible for over 30 percent of global CO2 emissions. In the fight against climate change and for an environmentally friendly future, it is therefore particularly important to build in a sustainable and resource-saving way. But how to find the most climate-friendly among all the products? How is sustainable planning and building possible? The best way is with measurable data and transparency. This can be found in the Environmental Product Declaration (EPD). Environmental Product Declarations are a method for the standardised presentation of the environmental impacts of products or services. EPDs provide a data basis that maps the entire life cycle of a building product or parts thereof and quantifies its environmental impacts. Environmental Product Declarations are based on the international standard ISO 14025, which applies to all sectors, but the construction industry is the pioneer in its application. The idea is that the standardised collection of environmental data on building products creates a comparable basis for sustainable construction planning. Planners, architects and builders then use this information to make an informed decision when making their selection. They use the EPD to determine which building products will minimise the environmental impact of their project. This supports sustainable construction and advances climate protection. At the same time, a sustainable way of doing business is also supported, which aims to conserve resources and reduce environmental pollution. In addition, customers can use them as evidence for various building certification systems such as LEED, BREEAM or DGNB. The most important contents of an EPD In an EPD, the environmental impacts of a product are recorded along the entire life cycle or in parts, including raw material extraction, production, transport, use, disposal and recycling, among others. For each area, various environmental criteria such as greenhouse gas emissions and resource consumption are recorded and evaluated. These results or environmental indicators flow into the EPD and enable comparability between building products. An important component of an Environmental Product Declaration is the assignment of the product to a specific product category. This classification in the Product Category Rules (PCR) is necessary to establish comparability between similar products. In each product category, the relevant environmental factors are recorded and included in the EPD. Environmental Product Declarations and Life Cycle Assessments – two that belong together Life Cycle Assessments (LCA) and Environmental Product Declarations (EPD) are two key elements of sustainability in the construction industry that are closely linked. Simplified, one can say that the EPD is a standardised summary of the results of a LCA. The LCA is carried out in four phases. First the purpose and scope of the LCA is defined. This is followed by a life cycle inventory, which records data collection and calculation methods to quantify relevant inputs and outputs of a product system. In the impact assessment phase, potential impacts on the environment are analysed with the help of the results of the life cycle inventory. In the final evaluation, the results of the life cycle inventory and the impact assessment are considered together. Depending on the building product, there are different approaches to assessing environmental impacts. All start from cradle and differ over the further life cycle of the product. The concept “cradle to grave” covers all phases of a product’s life, from raw material extraction to production, transport, use and disposal. It shows the complete ecological footprint from beginning to end. The approach “cradle to gate” records the ecological footprint of a product until it leaves the factory gate and before it is transported to the consumer. It does not take into account further environmental impacts during use and disposal. “Cradle to cradle” is the most comprehensive consideration. It is based on the principle of the circular economy, where products are designed so that they can either be fully recycled or composted at the end of their life cycle. It avoids the generation of waste and promotes the conservation of resources. How does aquatherm support its customers and partners with the LCA? aquatherm has had an ISO-compliant LCA carried out for four product families, which has been verified by an independent institute. Based on these Life Cycle Assessments, aquatherm provides customers with the corresponding EPDs for their projects. The results show that aquatherm piping solutions made of polypropylene have clear advantages compared to other materials such as copper or steel with regard to energy consumption, greenhouse gas emissions, water consumption and the amount of waste.

Consumers keen to see progress, with 73% willing to spend more with greener organisations Progress towards a sustainable world risks being held back as UK businesses grapple with increasing costs and a lack of clarity around a credible path to net zero, despite a tripling of awareness of the importance of reducing emissions and the potential commercial opportunity amongst small and medium-sized enterprises (SMEs), according to research published by BSI. BSI, the UK National Standards Body, today publishes the third annual Net Zero Barometer. The research, drawn from interviews, a survey of 1,000 senior decision makers at UK SMEs and another of 1,000 UK consumers, finds that awareness of the importance of achieving net zero targets has almost tripled to 82% in two years[1], highlighting the opportunity for organizations to partner across their supply chains to accelerate progress. With many SMEs now also identifying the resulting cost benefits as a major reason to increase efforts in this area, it also suggests there’s a competitive edge to be gained by those that collaborate to pursue their net zero goals. Currently, only a third of SMEs are extremely confident[2] as to how to reach net zero, suggesting more clarity about doing so is needed. The report recommends that SMEs: While many SMEs have already delivered on ‘quick wins’, such as reducing waste (44%) or switching to LED bulbs (38%), the research finds there is more to be done on strategic thinking. 52% of those questioned had a net zero policy, while 17% – some 929,900 organizations[3] – have still to take key actions on becoming more sustainable, meaning they may risk falling short of  realizing their ambitions without further action. SMEs contribute over £2 trillion to the UK economy, giving them a critical role in progressing its net zero transition. Yet while Covid-19 pressures have somewhat subsided, the current geopolitical context means cost remains a vital obstacle. Nearly two thirds (63%) cited the cost-of-living crisis as the biggest inhibiting factor, followed by the energy crisis (50%). Many are calling for extra financial support: Over half believe that clean energy subsidies (56%) and government grants for new projects (52%) would help them meet targets. The barriers to progress come despite a separate survey showing that three quarters (73%) of consumers would pay more for an item or service from a company with good environmental credentials and a real commitment to hit net zero, with 93% of those in Gen Z[4] likely to be loyal to a climate friendly brand. Although value for money and factoring in inflation came top, in the same survey 48% of people noted environmental concerns as a consideration when they purchase goods or services. Notably, SMEs are increasingly recognizing the financial value of accelerating progress towards net zero. Two fifths cited the prospect of reduced costs as one of the main benefits, while 31% believed that doing so would be positive because it would enhance their image and reputation. Equally, with organizations looking at not only their own emissions but Scope 3 emissions in their supply chain, the report notes that for those organizations who supply others, transparency and clarity of carbon accounting is set to become an asset in winning contracts and growing the bottom line. The research emphasizes the importance of verifying environmental claims, with 94% of consumers saying that proper verification was important to them. Two-thirds of these said verification mattered because it demonstrates organizations aren’t just greenwashing, while 32% said verifying against best practice standards can provide a benchmark by which they can compare one business with another. The 2023 Net Zero Barometer also found that: Scott Steedman, Director-General, Standards at BSI said: “This year’s barometer gives me cause for optimism. With 82% of business leaders telling us that sustainability and achieving net zero is important to their business practice, we are seeing a growing commitment to decarbonizing by 2050, along with confidence that it is meaningful to turn long term ambition into immediate action. “At a time where the attention of many SME leaders is being diverted by economic pressures, they want help to navigate a path that is both credible and realistic. SMEs want to understand both where they are on this journey, and what that transition means for them and their stakeholders. They can benefit from having a clear roadmap  to how they’re going to achieve net zero, not only in their own operations, but also in their supply chains. Our research shows that with the right guidance – including the use of standards – SMEs are more than able to rise to this moment.” “Small businesses contribute more than £2 trillion in turnover to the UK economy. The collective impact they can have if they pull together and collaborate to meet net zero goals and ultimately accelerate progress to a sustainable world is significant.” [1] 82% of business leaders told us that sustainability and net zero was important, up from three in ten who believed their business had a responsibility to remove or reduce direct carbon emissions in 2021 [2] Question asked whether leaders were confident or extremely confident [3] Business population estimates for the UK and regions 2022, Gov.UK [4] Those born between the late 1990s and the late 2010s Building, Design & Construction Magazine | The Choice of Industry Professionals
