Carbon Footprint: Measurement Functions and How to Reduce It

Key Takeaways

Carbon footprint is the total greenhouse gas emissions from activities, organizations, products, or processes that are usually expressed in CO₂e.
Measuring a carbon footprint helps companies identify emission sources, set reduction priorities, and improve operational efficiency.
Companies can reduce their carbon footprint through energy efficiency, low-carbon energy, and optimized transportation and logistics.

Paying attention to carbon footprints should be our utmost priority because they can worsen climate change. The problem is that carbon footprints come from human activities across various sectors. That’s why efforts to reduce carbon footprints, one of which is using renewable energy, should be a priority for everyone.

So, what is a carbon footprint, and why is this concept important for business and industry activities? In the explanation below, we’ll explore its definition, purpose, and ways to reduce it.

What Is a Carbon Footprint?

A carbon footprint is the total greenhouse gas emissions produced directly or indirectly by an activity, organization, product, or process over a certain period. These emissions are usually expressed in carbon dioxide equivalents (CO₂e).

In a business context, a carbon footprint includes emissions generated by various company operations. Sources include fuel use in machines, vehicles, boilers, or generators; electricity consumption; production processes; and even supply chain activities.

The Function of Measuring Carbon Footprint

In business operations, a carbon footprint is not just a number that shows the amount of emissions a company produces. Applying the carbon footprint concept can help a company manage emissions while also evaluating operational activities.

So, what functions does measuring a carbon footprint serve in supporting business activities? Here are a few of them:

Identifying emission sources: Helps companies know which activities generate emissions, such as electricity use, fuel, transportation, and production processes.
Measuring emissions: Provides an overview of emissions from various activities so companies can monitor and evaluate them regularly.
Setting emission reduction priorities: Helps companies identify the biggest emission sources so reduction efforts can focus on the activities that contribute most.
Improving operational efficiency: Provides a basis for evaluating energy use and identifying efficiency opportunities in facilities and business processes.

The Relationship Between Carbon Footprint and Climate Change

The carbon footprint is closely linked to climate change because various human activities, industries, and business operations produce greenhouse gas (GHG) emissions.

For example, when fossil fuels are used to generate energy, run vehicles, or support production processes, these activities release emissions like carbon dioxide (CO₂) into the atmosphere. The increasing emissions raise the concentration of GHGs in the atmosphere.

Higher GHG concentrations trap more heat in the atmosphere. Over time, this raises Earth's average temperature, which triggers changes in climate patterns. These effects include increased risks of extreme weather, changes in rainfall patterns, droughts, and even rising sea levels.

How to Reduce Carbon Footprint

You can start reducing your carbon footprint by evaluating activities that generate emissions and finding ways to use energy and resources more efficiently.

In business and industrial operations, there are several steps to reduce their carbon footprint, including:

1. Improving Energy Efficiency

Energy efficiency is one of the first steps because energy use is directly related to operational emissions and the company's electricity consumption.

Companies can implement it through energy-efficient technology, optimized lighting systems, regular machine maintenance, and regulated cooling and heating systems.

In industrial facilities, companies can also evaluate energy consumption in every production process. This monitoring helps identify equipment that consumes too much energy, so corrective actions can target the sources with the biggest impact.

2. Switching to Low-Carbon Energy

Using low-carbon energy can also reduce emissions related to the company's energy consumption. Options include buying electricity from renewable energy sources or using renewable energy generators at company facilities.

One option is to install solar power plants (PV systems) to meet part of the facility's electricity needs. Renewable energy sources like solar, wind, geothermal, and hydro generate electricity with very low or even zero direct GHG emissions during generation.

3. Optimizing Transportation and Logistics

Transportation can produce emissions from company vehicle fuel use as well as from third-party logistics services. Therefore, companies also need to evaluate routes, cargo capacity, travel frequency, and the types of vehicles used.

Optimizing routes can reduce travel distance and fuel consumption during distribution. Companies can also improve vehicle utilization, making the number of trips needed to transport goods more efficient.

How Does CDI Reduce Carbon Emissions?

PT Chandra Daya Investasi Tbk (CDI) not only focuses on providing the best products and services for customers, but is also committed to reducing carbon emissions.

CDI prioritizes cutting emissions and waste as well as protecting ecosystems and biodiversity. Here are some of the efforts CDI carries out to reduce carbon emissions and mitigate their impact:

CDI manages renewable energy sources with a capacity of over 2,000 kWp and plans to increase the solar power plant capacity to 3 MWp. This initiative can reduce carbon emissions by around 730.73 tons per year and cut electricity costs by 40%.
PT Krakatau Chandra Energi (KCE) planted 214 trees in the KCE area in 2024 as part of a carbon emission reduction program.
CDI has implemented a continuous emissions monitoring system to track air emissions in real time.

In addition to the efforts mentioned above, KCE, as a subsidiary of CDI, also manages renewable energy solutions. The solar power capacity it manages has grown to 11 MWp. Currently, KCE manages 4 types of solar panel installations, namely on-grid solar panels, off-grid solar panels, on-grid with backup batteries, and hybrid.

That concludes the information you can learn about the carbon footprint. As a reliable business and a trusted #YourGrowthPartner, CDI continues to commit to energy transition and low-emission practices to support environmental sustainability.

Frequently Asked Questions (FAQ)

Do you still have questions about carbon footprint and climate change? Check out some frequently asked questions below to get a clearer understanding of this topic.

1. 4 Steps of the Carbon Cycle?

The four main steps in the carbon cycle include photosynthesis, respiration, decomposition, and the burning of fossil fuels. These processes move carbon between the atmosphere, living things, soil, and the environment.

2. How Do I Calculate My Carbon Footprint?

Calculating your carbon footprint involves many factors and can be done at different scales. That's why the result is an estimate, whether done by a company or an individual. In short, the calculation formula can be written as follows:

Carbon footprint = Activity data × Emission factor

3. How Can I Reduce My Carbon Footprint?

You can reduce your carbon footprint by choosing low-emission transportation, using electricity and water wisely, opting for renewable energy, and recycling usable waste so it does not become environmental pollution.

4. What Are Examples of Carbon Emissions?

Examples of carbon emissions include burning vehicle fuels, using electricity from fossil energy sources, and industrial production activities.
