Preparing greenhouse gas inventory and development of low-carbon production strategies for an existing organized industrial zone

As of 2023, there are a total of 354 Organized Industrial Zones (OIZs) in Turkey. Most of the OIZs, which account for 45% of Turkey's industrial production, are energy-intensive. Almost all of this energy is met from the central electricity production obtained by the use of fossil resources. Greenhouse gas emissions occur due to this intensive use of energy. Greenhouse gas emissions in the industrial sector, which has a large share in terms of greenhouse gas emissions worldwide, occur both from fossil fuels burned for energy use and from chemical reactions. In this thesis, firstly, the importance of green organized industrial zones was mentioned, and then, as an exemplary study, greenhouse gas emissions caused by natural gas, electricity and diesel fuel consumed within the borders of Kütahya 30 August Organized Industrial Zone were calculated and studies were carried out for mitigation activities. The base years are 2019, 2020 and 2021. Within the scope of "ISO 14064-1 Guideline and Specifications Standard for Calculation and Reporting of Greenhouse Gas Emissions and Removal at the Establishment Level" and "ISO 14067 Product Carbon Footprint Calculation Standard", the amount of greenhouse gases released to the atmosphere was calculated by using the data recorded by the enterprises on a yearly basis. While the direct emission from natural gas was calculated as 105394.84 tCO2e in 2019, this emission decreased in 2020 and reached its 2019 value again in 2021. Indirect emissions from imported electricity were 64269.12 tCO2e in 2019, while electricity-related emissions increased in 2020 and 2021. Direct emissions from diesel are considerably lower than those from natural gas and electricity in terms of quantity. However, while the emission from diesel fuel was 74.11 tCO2e in 2019, it decreased by 75.5% in 2020 and reached 29.49 tCO2e in 2021. A large part of the greenhouse gas generated due to both electricity and natural gas consumption originates from an organization operating in the field of tile-ceramic manufacturing and an organization operating in the field of paper-corrugated cardboard manufacturing. There are many organizations in different fields of activity in organized industrial zones. The study has shown that greenhouse gas emissions must be monitored in these regions and it is necessary to determine the source of greenhouse gas emissions, otherwise the proposed reduction methods will not be very effective.
