Introduction to Greenhouse Gas Calculation Services
Greenhouse Gas emissions have become an increasingly important issue for Indonesia’s fertilizer industry. The industry plays a major role in supporting agricultural productivity and national food security, but fertilizer production and use are also associated with significant emissions throughout their life cycle.
The fertilizer industry in Indonesia began developing in 1959 with the establishment of PT Pupuk Sriwidjaja (Pusri), a pioneer in the country’s urea fertilizer industry. Its first plant was built in Palembang and began operations in 1963 with a production capacity of approximately 100,000 tons of urea per year.
In 1964, the plant was officially inaugurated by First Deputy Prime Minister Chaerul Saleh, marking an important milestone in the development of Indonesia’s national fertilizer industry.
To meet the country’s increasing fertilizer demand, Pusri subsequently developed several additional production facilities, including Pusri II in 1974, Pusri III in 1976, and Pusri IV in 1977. These expansions significantly increased fertilizer production capacity and strengthened Indonesia’s ability to support domestic agricultural development.
In 1979, the Indonesian government appointed Pusri to distribute subsidized fertilizers throughout the country as part of the national food security program. This role further demonstrated the strategic importance of the fertilizer industry in supporting farmers and maintaining agricultural productivity.
Development of Indonesia’s Fertilizer Industry Holding Company
In 1997, the Indonesian government transformed PT Pupuk Sriwidjaja into a holding company responsible for coordinating several fertilizer and related companies, including PT Petrokimia Gresik and PT Pupuk Kujang.
The transformation was intended to improve the efficiency of fertilizer production, distribution, investment, and overall industry management across Indonesia.
In 2012, the holding company was renamed PT Pupuk Indonesia (Persero), strengthening its position as the state-owned holding company for Indonesia’s fertilizer industry.
Several major companies operate within the broader Pupuk Indonesia Group, including:
- PT Petrokimia Gresik
- PT Pupuk Kujang
- PT Pupuk Kalimantan Timur
- PT Pupuk Iskandar Muda
- PT Rekayasa Industri
These companies contribute to fertilizer production, engineering, distribution, and other supporting activities that are essential to Indonesia’s agricultural sector.
Greenhouse Gas Emissions in the Fertilizer Industry
The fertilizer industry plays an essential role in improving agricultural productivity and supporting national food security. However, fertilizer manufacturing and use can also generate substantial Greenhouse Gas emissions.
Fertilizer production involves energy-intensive industrial processes and chemical reactions. For example, ammonia production typically requires significant amounts of energy and may generate large quantities of carbon dioxide (CO2), particularly when fossil fuels are used as feedstock or energy sources.
Nitrogen-based fertilizers also have an important connection to climate change. When nitrogen fertilizers are applied to agricultural soils, microbial processes in the soil can generate nitrous oxide (N2O).
Nitrous oxide is a powerful greenhouse gas with a substantially greater global warming effect per unit of mass than carbon dioxide. For this reason, emissions associated with fertilizer application need to be considered when evaluating the overall climate impact of fertilizer products.
It is also important to distinguish between different gases produced during fertilizer manufacturing. Carbon dioxide and nitrous oxide are greenhouse gases, while other compounds such as ammonia and nitrogen oxides can contribute to environmental and atmospheric impacts but are not all classified as direct greenhouse gases in the same way.
Understanding Scope 1, Scope 2, and Scope 3 Greenhouse Gas Emissions
Corporate Greenhouse Gas emissions are generally categorized into three scopes. This classification helps companies understand which emissions originate directly from their operations and which occur throughout their wider value chain.
- Scope 1: Direct greenhouse gas emissions from sources owned or controlled by the company. Examples include emissions from fuel combustion, industrial equipment, production facilities, and company-owned vehicles.
- Scope 2: Indirect emissions associated with purchased electricity, steam, heating, or cooling consumed by the company. Although these emissions occur at the energy producer’s facilities, they are associated with the energy consumed by the reporting company.
- Scope 3: Other indirect emissions occurring throughout the company’s upstream and downstream value chain that are not included within Scope 1 or Scope 2. These can include purchased raw materials, transportation, business travel, waste, capital goods, distribution, product use, and end-of-life treatment.
For fertilizer manufacturers, Scope 3 can represent a significant component of the company’s total carbon footprint because fertilizer products continue to generate climate impacts after leaving the production facility.
Scope 3 Greenhouse Gas Emissions in the Fertilizer Industry
Scope 3 Greenhouse Gas emissions in the fertilizer industry can originate from numerous activities throughout the fertilizer value chain.
The environmental impact of fertilizer does not end when the product leaves the factory. Emissions can occur during extraction and production of raw materials, transportation, storage, distribution, agricultural application, and other stages of the product life cycle.
This creates a complex carbon footprint in which both upstream suppliers and downstream customers can influence the total greenhouse gas emissions associated with fertilizer products.
Understanding these emission sources is essential for fertilizer companies seeking to develop accurate greenhouse gas inventories and effective decarbonization strategies.
Raw Material Production and Greenhouse Gas Calculation Service Emissions
One important source of Scope 3 emissions comes from purchased raw materials and other inputs used in fertilizer manufacturing.
Depending on the type of fertilizer being produced, these materials may include phosphate rock, potash, sulfur, chemicals, catalysts, packaging materials, and other industrial inputs.
Mining, processing, refining, and transporting these materials consume energy and generate emissions before the materials even reach the fertilizer manufacturing facility.
For companies seeking to reduce Scope 3 emissions, understanding the carbon footprint of purchased materials can therefore be an important first step.
Companies may also engage with suppliers to encourage energy efficiency, renewable energy adoption, more sustainable production processes, and improved greenhouse gas reporting.
Transportation and Distribution Emissions
Transportation is another important source of Scope 3 emissions within the fertilizer value chain.
Raw materials may need to be transported from mines, chemical facilities, ports, or other suppliers to manufacturing plants. Finished fertilizer products are then distributed to warehouses, distributors, retailers, cooperatives, and farmers across Indonesia.
Transportation by trucks, ships, trains, or other fossil fuel-powered vehicles can generate significant carbon dioxide emissions.
Companies can potentially reduce these emissions by improving logistics efficiency, optimizing transportation routes, maximizing vehicle loads, increasing the use of lower-carbon transportation, and selecting strategically located distribution facilities.
Greenhouse Gas Emissions from Fertilizer Use
One of the most important downstream sources of emissions in the fertilizer industry occurs when fertilizers are used in agricultural fields.
When nitrogen fertilizer is applied to soil, not all nitrogen is absorbed by crops. Biological and chemical processes can transform some of this nitrogen and result in nitrous oxide emissions.
For a fertilizer manufacturer, emissions generated from the use of sold fertilizer products may become a relevant component of downstream Scope 3 emissions.
This means that fertilizer companies seeking to understand their complete climate footprint need to look beyond factory emissions and consider how their products are ultimately used by farmers.
Improving fertilizer efficiency can therefore provide an important opportunity to reduce emissions while maintaining agricultural productivity.
Reducing Scope 3 Greenhouse Gas Emissions from Fertilizer Use
Reducing fertilizer-related emissions does not necessarily mean eliminating fertilizer use. Instead, one important strategy is improving fertilizer-use efficiency so that crops receive the nutrients they need while unnecessary nitrogen losses are minimized.
Precision agriculture, soil testing, appropriate fertilizer application rates, timing optimization, and improved nutrient management can help farmers use fertilizer more efficiently.
Fertilizer manufacturers can support these efforts by developing more efficient fertilizer products, providing technical guidance, supporting farmer education, and investing in research and innovation.
These approaches can potentially reduce emissions while also improving agricultural productivity and lowering unnecessary fertilizer costs.
Renewable Energy and the Fertilizer Value Chain
Renewable energy can play an important role in reducing greenhouse gas emissions from fertilizer production. Solar power, wind energy, renewable electricity, and low-carbon hydrogen technologies may help reduce dependence on fossil fuels.
However, renewable energy technologies also have life-cycle emissions associated with manufacturing equipment, constructing infrastructure, transporting materials, and other upstream activities.
These emissions are generally much lower than those associated with conventional fossil energy over their life cycle, but they may still need to be considered when companies prepare comprehensive Scope 3 greenhouse gas inventories.
How to Calculate Scope 3 Greenhouse Gas Emissions
Calculating Scope 3 emissions requires companies to first map their value chain and identify relevant emission sources.
The company can then collect activity data such as quantities of raw materials purchased, transportation distances, fuel use, products sold, fertilizer application volumes, waste generated, and other relevant information.
This activity data is combined with appropriate emission factors to estimate greenhouse gas emissions in units of carbon dioxide equivalent (CO2e).
The quality of the greenhouse gas inventory depends heavily on the quality of the underlying data. Primary data from suppliers and business partners can provide more accurate results, while secondary emission factors may be used where direct data is unavailable.
Companies should also maintain clear methodologies, calculation assumptions, data sources, and documentation so that greenhouse gas calculations can be reviewed and updated consistently.
Why Scope 3 Greenhouse Gas Calculation Is Important
Understanding Scope 3 emissions allows fertilizer companies to identify emission sources that may not be visible when only Scope 1 and Scope 2 are considered.
For example, a company may successfully reduce emissions from its own manufacturing facilities while still having substantial emissions associated with raw materials, transportation, or fertilizer application.
A comprehensive greenhouse gas inventory can therefore help management determine where emission reduction initiatives are likely to have the greatest impact.
It also provides a stronger foundation for setting climate targets, developing decarbonization strategies, engaging suppliers, and monitoring progress toward sustainability commitments.

The Future of Greenhouse Gas Management in the Fertilizer Industry
The fertilizer industry will continue to play an essential role in supporting Indonesia’s food security and agricultural development. However, the sector must also respond to increasing pressure to reduce its climate impact.
Managing Greenhouse Gas emissions requires companies to look beyond their own facilities and understand emissions across the complete fertilizer value chain.
Scope 3 emissions from raw materials, logistics, distribution, and fertilizer application can represent significant opportunities for emission reduction.
By improving greenhouse gas inventories, engaging suppliers, optimizing logistics, supporting efficient fertilizer use, adopting renewable energy, and investing in low-carbon technology, fertilizer companies can gradually reduce their climate footprint.
Greater transparency regarding Scope 3 emissions can also strengthen confidence among consumers, investors, regulators, and other stakeholders while encouraging companies to continue developing more sustainable solutions.
Understanding the full contribution of fertilizer production and use to climate change is therefore an important step toward building a more sustainable agricultural sector and protecting the environment for future generations.
