Il Gruppo NSG si impegna a ridurre i rischi legati al cambiamento climatico.
L'obiettivo originale del Gruppo NSG di ridurre le emissioni di gas serra, approvato dall'iniziativa Science Based Target (SBTi) nell'ottobre 2019, è stato rivisto nel corso del FY 2012. Il nuovo obiettivo è molto più sfidante e rappresenta la più grande ambizione del Gruppo NSG per ridurre le emissioni di carbonio nelle proprie attività. Il nuovo obiettivo è stato formalmente approvato dall'SBTi nel maggio 2022 ed è allineato ad uno scenario di riscaldamento globale ben al di sotto dei 2℃. Oltre a questo nuovo livello, il nuovo obiettivo include anche l'impegno nel ridurre le emissioni dell'Ambito 3.
Entro il 2030, Gruppo NSG si impegna a ridurre le emissioni assolute di gas serra (Ambito 1, Ambito 2 e Ambito 3) del 30% rispetto al livello di riferimento del 2018.
Il Gruppo NSG, durante la presentazione dei risultati finanziari dell'anno fiscale FY22 alla Borsa di Tokyo (maggio 2022), ha annunciato il suo impegno nel raggiungere la neutralità delle emissioni di carbonio entro il 2050. Questo obiettivo è in linea con le numerose richieste degli stakeholder lungo tutta la catena del valore di NSG. L'obiettivo copre tutti gli ambiti delle emissioni di gas serra di NSG, senza esclusioni.

The main emissions from a flat glass furnace come from the combustion of fuel and the decomposition of the carbonate and sulphate raw materials. The raw materials are melted at a very high temperature, so the process is extremely energy-intensive.
The most significant pollutants from a glass furnace are: carbon dioxide, from both the decomposition of carbonates and combusted fuels, nitrogen oxides formed from the nitrogen and oxygen in the air at high temperature; sulphur oxides from the refining agent (and from oil fuel if that is used) and particulate matter derived from compounds volatilized from the molten glass.
We are tackling pollutant air emissions with a range of primary and secondary abatement techniques. Primary methods, such as special burners or carefully chosen raw materials, including more cullet (recycled glass), reduce pollutant formation and can also improve the thermal performance of the furnaces. Secondary abatement removes the pollutants from the furnace waste gases before they are emitted through the chimney.

In glassmaking, water is used for cooling, and most of our plants operate with closed loop systems and so only require top up. Water is also used for washing glass in plants but there the need is for very high purity, so water is treated and then reused. We seek to minimize our water consumption by working with suppliers to recycle water and to install advanced water treatment facilities. This not only reduces the consumption of water itself but also the chemicals used in the treatment of the water.

According to a Glass for Europe publication, the flat glass sector is indispensable to the massive decarbonisation of the building, transport and energy sectors, which represent the lion’s share of Europe’s CO₂ emissions. Flat glass manufacturing is also an energy-intensive activity. The sector takes it as its duty to reduce its own CO₂ emissions, which represents a significant challenge in moving towards carbon neutrality. In today’s climate urgency context, the flat glass sector wants to offer its vision of a rapidly actionable virtuous decarbonisation cycle.

Yes. The NSG Group is fully committed to reduce adverse environmental impact by maximising the reuse, recycling or recovery of resources and minimising the production of waste involved in glass manufacture, processing, packaging, and delivery.
Although current levels within the flat glass industry are low, we are seeking to increase the levels of pre-consumer recycled content in our manufacturing processes. We do make active use of recycled glass, referred to as cullet, in our processes to improve our environmental performance. Internal and pre consumer cullet consists of broken glass generated from edge trimmings and off specification product. While internal and pre consumer cullet is generated from the manufacturing process, it is reintroduced into the float furnace and makes up approximately 20 % of the batch materials used to manufacture flat glass (dependent upon product). The use of cullet is essential to the manufacturing of quality flat glass and has the benefit of improving the melt of other batch material, reduces the amount of virgin material that must be extracted and generates a net energy savings. Since combustion processes are heavily involved in the manufacture of flat glass this energy saving reduces emissions into the atmosphere.
In addition to cullet, batch material also includes silica sand (one of the world's most abundant naturally occurring minerals) and other abundantly available minerals such as limestone.

Float glass manufacture is an energy-consuming process, but many of our products reduce energy consumption when used in buildings. It is important to consider this overall balance when assessing environmental impact.
Energy issues are key to the building glass industry, as glass products can make an important contribution to combating climate change. Different types of glass we have developed over the years, especially low-emissivity double glazing and solar control glazing, can significantly reduce the need for heating and cooling in buildings, thereby reducing energy consumption and associated carbon dioxide (CO₂) emissions.
In regions where the ambient temperature is often uncomfortably hot, the increasing tendency, as people aspire to a better lifestyle or have more disposable income, is to install air conditioning and that of course brings with it an energy and carbon burden. In that case, the primary objective is to keep heat out. Residential and non-residential buildings that use more energy than necessary to stay cool are a major source of unnecessary CO₂ emissions. Solar control glass allows sunlight to pass through glazing while radiating and reflecting away a large degree of the sun’s heat. The indoor space stays bright and much cooler than would be the case if normal glass were used.
The huge potential for energy savings and CO₂ emission reductions from using high performance glazing in Europe has been quantified in a study from Glass for Europe.
Commissioned by the European trade association of flat glass manufacturers, of which NSG Group is an active member, comprehensive modelling was undertaken by Dutch scientific institute TNO.
The research reports energy and CO₂ savings that can be realised for heating and cooling of buildings across EU Member States by 2030 and 2050.
If all buildings in Europe were installed with windows incorporating high performance glazing, the study found that:
75 Mtoe1 of energy could be saved annually, equivalent to a reduction of energy consumption of nearly 30% in buildings;
Almost half of these energy savings can be realised in 10 years, by doubling the annual window renovation rate;
Up to 94 million tonnes of CO₂ emissions per year could be avoided.
1 Mtoe is one million tonnes of oil equivalent.
The findings of this research emphasise the need for EU and national policies to put energy efficiency first and increase renovation rates of our building stock using high performance glazing available on the market today.
More information about this study, including a breakdown for each country, can be found in the Glass for Europe 'Glazing Potential' publication:

In most cases, the finished product does not contain hazardous substances. Glass is produced from non-toxic, naturally occurring substances (e.g. sand, limestone, dolomite etc.). Glass is an inert material. Hazardous substances may be used during the subsequent processing of the glass. These are carefully managed on our sites to ensure no harmful release to the environment and are rendered harmless in the final product. The Group is active in ensuring that its most critical supplies are REACH compliant.
Volatile Organic Compounds (VOCs) are not used in the manufacture of flat glass. Although they may be used during the back painting process, there are no VOCs present in the finished product.
In Europe, much of our glass is transported on steel stillages – in cycles with the customers – without packaging and utilizing specialist 'Floatliner' vehicles for the large raw glass plates. We use a significant quantity of renewable wooden packaging in our operations and work with our suppliers to design reusable units. Due diligence is carried out to ensure that timber comes from legal and sustainable sources.
