Science Based Targets (SBT)
The Greenhouse gas reduction target of NSG Group has been approved by the Science Based Targets initiative (SBTi*) in October 2019 as "a science-based target to limit the average rise of global temperature to below 2℃ from pre-industrial revolution levels" in line with the goals of the Paris Agreement.
By 2030, NSG Group targets to reduce absolute GHG emissions (Scope 1 and Scope 2**) by 21 per cent compared to the 2018 level.
Committed to help mitigate risks of climate change, NSG Group is actively pursuing the following measures:
- Converting the energy source in glass manufacturing processes from heavy oil to natural gas.
- Implementing the measures, including the use of LED lights, inverters and waste heat, to reduce CO2 emissions in glass manufacturing processes.
- Expanding the use of renewable energy.
- Supplying the glass products highly effective in saving and generating energy to reduce CO2 emissions.
By reducing CO2 emissions from business operations and supplying innovative glass products, NSG Group will continue its contributions to mitigating climate change risks.
emission and SBT
*SBTi is a partnership between CDP (former Carbon Disclosure Project), UN Global Compact, WRI (World Resources Institute) and WWF (World Wildlife Fund), which helps companies set the science-based goals for reducing GHG emissions to prevent the impact of climate change.
**Scope 1: Direct emissions by business operators (Use of fuel in manufacturing processes, etc.)
Scope 2 Location: Indirect emissions by consumption of energy sources (Purchased electricity used in manufacturing processes, etc.)
CO2 emission reduction target toward FY24
In 2020, NSG Group was responsible for the emission of 3.3 million tonnes of CO2e. This is an eleven percent decrease on the previous year due to a combination of the impact of low process utilization associated with the Covid-19 pandemic, increases in the proportion of renewable electricity use and many proactive operational energy and CO2 saving initiatives as described in the energy use section.
Our scope 1 emissions were 2.8 million tonnes. These direct emissions occur from a combination of the combustion of fossil fuels within the manufacturing process, transportation of product and the decomposition of carbonate raw materials in the glass melting process.
Our scope 2 emissions (market based approach) were 0.5 million tonnes of CO2e. Scope 3 emissions were estimated at 3.0 million tonnes of CO2e. This 3 figure has increased since last year due to improved scope 3 reporting.
In the operation of our float plants, heavy oil to natural gas conversion has helped to reduce carbon emissions by around 50 percent over the past 40 years and a combination of design and operational innovations have made further progress.
We have introduced a revised target for CO2e emission per tonne of equivalent product, with the new target being an 8% improvement in this metric by end of FY24 compared to FY18 baseline.
During FY21, numerous decarbonization project activities continued to be implemented. The benefit of these project was more than offset by the continued market deterioration due to Covid19 pandemic resulting in the KPI not being achieved.
