It feels like only yesterday that heads of state were descending on Glasgow for COP26, yet COP27 is already upon us.

So, what has changed since global leaders and climate influences met in Scotland 12 months ago? And is the architectural and construction community any further down the path to achieving net zero targets by 2050?

Judging by the tone and content of marketing collateral and company websites you would be mistaken for thinking the sector is well on track. Unfortunately, greenwashing is still much in evidence within the industry and manufacturers are, knowingly or otherwise, using unsupported or exaggerated claims to boost their green credentials.

Probably the most common form of this is the abuse of carbon offsetting, where an organisation prioritises this practice without addressing their own in-house emissions. Now, it is fair to say that there is nothing wrong with offsetting in itself. In fact, a lot of good can arise from these practices. However, it needs to be done in addition to other efforts to reduce direct emissions across business operations.

For those product manufacturers planting trees in developing nations yet doing nothing to drive down their own carbon footprint, it is an incredibly short-sighted strategy. Especially when specifiers are now acutely aware of the importance of sustainability within the contemporary design brief.

I believe failure to act now will also have a knock-on effect. Manufacturers considered unreliable or disingenuous in their green claims might see other questions raised around general product performance, such as durability and safety. Ultimately, 鈥渉onesty is the best policy鈥� should be the approach for all involved.

However, to achieve this most assertive and transparent approach, we need to be realistic. Complete change won鈥檛 happen overnight but playing into the current catastrophising narrative is actually creating barriers rather than removing them.

Instead, we should be starting with 鈥渆asy wins鈥� that lead into bigger sustainability targets. If architectural product manufacturers are serious about meaningful change, and doing the right thing by their clients, then it starts with baby steps, setting realistic goals and deadlines that can help build momentum.

It is an approach that has been working for us as we seek to drive down emissions throughout our operations, from the raw materials we purchase to the machinery and transport we use. Starting with the performance evaluation of our supply chains, it is helping us to become transparent and accountable so that audiences can see for themselves which products achieve the lowest lifetime embodied carbon.

Recent research has shown that those who switch to a circular economic model can expect less demand for new materials. In turn, less energy is needed in extraction, resulting in further savings

Reviewing supply chains has also been an important measure in creating a more circular production process which, given the climate emergency, I believe needs to be at the heart of all building product manufacturers鈥� businesses. An ethos of 鈥渞ecycle鈥� and 鈥渞euse鈥� is just one part of a multi-faceted approach to encourage more sustainable working practices.

It isn鈥檛 just our own business that can benefit. Recent research has shown that those who switch to a circular economic model can expect less demand for new materials. In turn, less energy is needed in extraction, resulting in further savings.

Furthermore, new regulations, particularly Part Z, can help to guide this more open and responsible approach. For example, keeping product information as detailed and up to date as possible 鈥� be it carbon performance or safety data 鈥� and leaving no stone unturned is essential.

Specifiers have their own role to play to effect change, calling out greenwashing when they see it and demanding more of their suppliers. This will all help to raise the bar.

Ultimately, greenwashing is a persistent problem which needs to be stamped out of the construction sector for good. However, it will require a degree of systematic change, not just from the industry, but also at the highest levels of policy, creating a more nuanced framework for carbon reduction, understanding that different businesses will need to go at different paces.

We have a bad habit in this country of comparing apples with oranges and it needs to stop if we want to turbo-charge carbon reduction in a meaningful, tangible and transparent way.
