With rising global emissions, it's clear that all organisations must take responsibility to reduce their carbon footprint.
Luckily, new SaaS solutions offer SMEs an accessible way to accurately measure and manage emissions across operations.
By leveraging these tools, SMEs can benchmark current emissions, identify reduction opportunities, and track progress - enabling meaningful climate action aligned with stakeholder expectations and regulatory standards.
The Role of SaaS in Identifying the Source of Carbon Dioxide Emission
This introductory section outlines the increasing need for small and medium-sized enterprises (SMEs) to accurately measure their carbon emissions using SaaS solutions in order to effectively reduce their impact on climate change.
Understanding Global Greenhouse Gas Emissions
Greenhouse gas (GHG) emissions, especially carbon dioxide (CO2), are a major contributor to climate change. According to the Intergovernmental Panel on Climate Change (IPCC), CO2 emissions from fossil fuel combustion and industrial processes accounted for about 78% of the total GHG emissions increase from 1970 to 2010. Reducing these emissions is crucial to mitigate climate change risks.
SMEs have an important role to play in global emission reduction efforts. However, many lack the tools to accurately measure their carbon footprint across business operations and supply chains. This hampers their ability to identify emission hotspots and opportunities to lower emissions.
The Rise of CO2 Emissions in 2023 and the Role of SMEs
Global CO2 emissions are projected to rise by 1% in 2023, reversing a temporary decline caused by the COVID-19 pandemic. This renewed growth underscores the urgency for climate action across all sectors of the economy.
SMEs collectively account for a substantial portion of global emissions. Equipping them with SaaS solutions to map emissions sources lets them benchmark performance, set reduction targets, and track progress over time. Leading by example, SMEs can positively influence larger corporations and accelerate economy-wide decarbonisation.
Decoding the Biggest Greenhouse Gas Emitters by Country
China, the United States, EU27+UK and India are the world’s top emitters - contributing over 60% of global greenhouse gas emissions. Within these countries, power generation, manufacturing industries and transport sectors are major CO2 sources.
For SMEs, understanding emissions on a country and sector basis allows customised benchmarking to pinpoint energy-intensive processes and higher emission activities across operations. This granular insight assists in prioritising and directing reduction efforts for maximal impact.
Mapping Emissions: A Crucial Step for Regulatory Compliance
Many countries now have emissions monitoring and reporting regulations such as the EU's Monitoring and Reporting Regulation. Non-compliance can lead to hefty fines.
SaaS tools that seamlessly generate real-time emissions data across the value chain facilitate compliance for SMEs. The automated and streamlined carbon accounting eliminates manual tracking while still meeting rigorous regulatory standards.
Stakeholders’ Expectations for Carbon Transparency
Stakeholders like investors, employees and customers now expect businesses to provide climate action plans with emissions reduction commitments.
SaaS platforms enable SMEs to accurately disclose emissions profiles via automated data collection and analytics. This satisfies stakeholders seeking reliable and granular climate risk reporting while building brand reputation as a sustainability leader.
What is the main source of emissions of carbon dioxide?
Fossil fuel combustion is the primary source of global carbon dioxide (CO2) emissions. According to the Intergovernmental Panel on Climate Change (IPCC), the burning of coal, natural gas, oil and other fossil fuels accounted for over 75% of total global greenhouse gas emissions and nearly 90% of all CO2 emissions in 2019.
The IPCC further breaks down CO2 emissions by sector, with electricity and heat production making up 42% of emissions. This includes emissions from coal, natural gas and oil power plants that generate electricity and provide heating around the world. Transportation is the second largest source at 24% of CO2 emissions globally, encompassing road vehicles, ships, trains and air travel. Next is industry at 19%, covering emissions from industrial processes like cement, steel and chemical production. The remaining CO2 emissions come from buildings, agriculture and other land use changes.
Within specific countries and regions, the main CO2 emission sources can vary. For example, China generates nearly half its emissions from industry and construction, while the United States produces most of its emissions from electricity and transportation. But across all countries, the predominance of fossil fuel use for power, heat, vehicles and manufacturing makes it overwhelmingly the primary driver of rising CO2 levels causing climate change.
Reducing reliance on coal, oil and natural gas by transitioning to renewable energy sources and achieving higher efficiency in all sectors represents the most direct path to curbing CO2 emissions worldwide. Understanding the main emission sources also allows countries to tailor climate action plans that target their largest contributors. With concerted mitigation efforts across all major emitters, the goal of reaching net zero emissions by 2050 to limit global warming becomes more feasible.
What are the 4 main sources of carbon dioxide?
Carbon dioxide (CO2) is a major greenhouse gas contributing to climate change. There are both natural and human-caused sources that emit CO2 into the atmosphere.
The 4 main sources of carbon dioxide emissions are:
1. Decomposition and Respiration
Decaying organic matter and plant and animal respiration release CO2 naturally. This includes decomposition of dead plants and animals and respiration from living plants and animals.
2. Ocean Release
The oceans hold large amounts of dissolved CO2. Changes in temperature, currents and biological activity cause the oceans to release CO2 into the atmosphere.
3. Deforestation
Cutting down and burning forests releases the CO2 stored in trees and vegetation. Deforestation is a major contributor to rising atmospheric CO2 levels.
4. Fossil Fuel Combustion
The burning of fossil fuels like coal, oil and natural gas for electricity, heat and transportation is the primary source of human-caused CO2 emissions. The CO2 has been locked underground for millions of years and burning these fuels releases it into the air.
Understanding the source of CO2 emissions can help businesses and governments make informed decisions to mitigate climate change. Regularly tracking emissions and their sources with tools like EcoHedge's SaaS solutions is an important first step.
What are the 3 largest sources of carbon dioxide?
Deforestation, agriculture, and fossil fuel combustion are considered the three largest sources of global carbon dioxide emissions.
Deforestation
Deforestation contributes to rising CO2 levels when trees are cut down or burned. Trees absorb and store carbon dioxide through photosynthesis, so losing forests means more CO2 stays in the atmosphere.
It's estimated that deforestation accounts for roughly 10-15% of total human-caused CO2 emissions globally each year. Most deforestation is driven by converting forests into agricultural land as the human population grows and the demand for food increases. Clearing forests for timber, ranching, palm oil plantations, and development also play a major role.
Agriculture
The agriculture sector generates CO2 and other greenhouse gases from activities like applying fertiliser, operating farm equipment, managing livestock manure, and growing rice in flooded paddies.
Agriculture makes up an estimated 11-15% of annual global greenhouse gas emissions from human activities. The majority comes from nitrous oxide from fertilisers and methane from livestock and rice farms. As food production expands to feed more people, agriculture's contribution to climate change is likely to keep rising.
Fossil Fuel Combustion
Burning coal, oil, and natural gas to generate energy for power, heating, industry, and transport releases roughly 35 billion metric tons of CO2 per year. That makes fossil fuel use by far the biggest source, responsible for over 65% of total global CO2 emissions.
Most experts agree the only way to stabilise Earth's climate is to drastically reduce our dependence on fossil fuels by transitioning to renewable energy and achieving net zero emissions by 2050.
What is the primary source of CO2 emissions?
The largest source of carbon dioxide (CO2) emissions globally comes from burning fossil fuels such as coal, oil, and gas for electricity, heat, and transportation.
Here are some key facts about the primary sources of CO2 emissions worldwide:
- Power Generation: Electricity and heat production accounts for about 25% of total CO2 emissions. Most power plants rely on fossil fuels like coal, oil, and natural gas to generate electricity. As energy demand rises globally, power generation remains the biggest contributor to CO2 emissions.
- Transportation: Transportation including cars, trucks, ships, trains, and airplanes accounts for about 14% of global CO2 emissions. Most modes of transport still depend heavily on oil and petroleum-based fuels. With more vehicles on the road globally, transportation-related emissions continue to rise.
- Manufacturing and Construction: Manufacturing cement, steel, and other goods accounts for about 24% of CO2 emissions. Construction, including building homes, offices, roads, bridges etc., represents 11% of emissions. These sectors rely heavily on fossil fuels and are major contributors to rising CO2 levels.
- Commercial and Residential: Heating and cooking in homes, offices, malls, and other buildings represents about 17% of global CO2 emissions. This mostly comes from burning oil, natural gas, propane etc. Improving building energy efficiency is key to reducing emissions from this sector.
So in summary, burning fossil fuels to generate electricity and heat, power transportation, drive industrial processes, and heat/cool buildings are the primary sources of CO2 emissions driving climate change. As the world economy expands, these sectors are expected to account for an even greater share of total greenhouse gas emissions.

Grasping the Complexity of CO2 Emissions by Energy Source
Different energy sources contribute varying amounts of carbon dioxide (CO2) emissions, making it complex for businesses to track and reduce their footprint. Software-as-a-Service (SaaS) solutions can help simplify this process.
The Predominant Role of Fossil Fuels
Fossil fuels like coal, oil, and natural gas are the largest contributors to global CO2 emissions. In 2019, fossil fuels accounted for over 80% of total U.S. greenhouse gas emissions from human activities. As the main source of emissions, transitioning from fossil fuels to renewable energy is critical for climate change mitigation efforts. SaaS tools can help SMEs understand where fossil fuels are used in their operations and identify opportunities to switch to cleaner alternatives.
Renewable Energy: A Comparative Analysis
Unlike fossil fuels, most renewable energy technologies like solar, wind, geothermal and hydropower produce little to no CO2 emissions. In 2020, renewable energy sources accounted for about 20% of U.S. electricity generation and 12% of total U.S. energy consumption. As more SMEs make the switch, SaaS platforms can track reduced emissions and provide benchmarking to showcase the benefits over fossil fuels.
Energy Efficiency as a Strategy for Emissions Reduction
In addition to switching energy sources, SMEs can lower emissions through energy efficiency initiatives like equipment upgrades, optimised operations and employee behavioural changes. The EPA estimates that energy efficiency improvements over the past several decades avoided approximately 800 MMTCO≈e in U.S. carbon emissions in 2020 alone. SaaS tools can identify energy hotspots and calculate potential savings from efficiency projects.
Challenges in Tracking Emissions Across Diverse Energy Sources
With various direct use of fuels plus purchased electricity and heat production, tracking emissions can be overwhelmingly complex for SMEs. SaaS carbon accounting platforms integrate usage data from utility bills, fleet vehicles, travel, purchased goods and more to quantify emissions across all scopes and categories. This provides comprehensive insights for SMEs to minimise their footprint.
SaaS Solutions: A Gateway to Global CO2 Emissions by Sector
SaaS tools provide an effective means for companies to measure, report on, and reduce their carbon emissions across industry sectors. As the main contributors to global emissions, tackling sector-specific footprints is key to mitigating climate change.
Overview of IPCC Emissions by Sector
The IPCC has categorised global greenhouse gas emissions into four broad sectors:
- Energy - Includes emissions from electricity/heat production, manufacturing/construction, transportation, fugitive emissions, and fuel production/use. Accounts for ~72% of emissions.
- Industrial processes and product use (IPPU) - Covers emissions from mineral, chemical, metal production, and product use like solvents and lubricants. Contributes ~9% of emissions.
- Agriculture, forestry, and other land use (AFOLU) - Encompasses agricultural emissions from livestock, soils, and rice production as well as land use changes like deforestation. Generates ~13% of emissions.
- Waste - Consists of emissions from solid waste disposal, wastewater treatment, and incineration. Accounts for 3-4% of total emissions.
The energy and IPPU sectors involving fossil fuel combustion are the largest contributors. As small and medium enterprises (SMEs) operate across these sectors, emissions tracking tools can aid their decarbonisation efforts.
Identifying the Biggest CO2 Emitters by Industry
