Charting the Course for SMEs Towards Lower Total GHG Emissions
Small and medium-sized enterprises (SMEs) have a crucial role to play in reducing global greenhouse gas (GHG) emissions. As the world races to meet ambitious climate targets set out in agreements like the Paris Accords, SMEs must actively track and reduce their carbon footprints.
Failing to engage with emission reduction efforts can carry major risks. SMEs may face public backlash, struggle to secure investment and partnerships, or lose traction amid evolving sustainability regulations. Meanwhile, proactive SMEs stand to gain competitive advantages, cost savings, trust from stakeholders, and more.
This section will overview key considerations for SMEs seeking to understand and navigate the landscape of total GHG emissions.
Navigating Total GHG Emissions by Year: The Rising Tide of Climate Targets
Around the world, governments and corporations have set aggressive GHG reduction goals. For example, the EU aims to cut emissions by at least 55% by 2030. Major companies like Microsoft and Unilever have committed to net-zero emissions by 2030 and 2039 respectively.
To align with global climate ambition, SMEs must track their annual emissions over time. This allows them to set science-based targets, monitor performance, and identify the most impactful abatement opportunities year-over-year.
For example, an SME may find their largest emission source is purchased electricity. By switching to renewable energy, they could dramatically cut annual emissions. Tracking total GHG output yearly enables informed strategic decisions.
As top-line climate targets grow more ambitious, SMEs that actively manage emissions yearly can get ahead of the curve - while laggards may scramble to catch up later.

Stakeholder Trust: Employees, customers and investors increasingly demand climate accountability. High-performing SMEs on emission reductions can improve talent recruitment and retention, drive sales, and build investor confidence.
In summary, SMEs must actively engage with regular GHG tracking and science-based reduction targets. Beyond environmental impact, these efforts unlock strategic opportunities and mitigate regulatory risks. The time for climate action is now.
What is total greenhouse emissions?
Total greenhouse gas (GHG) emissions refers to the combined emissions of various gases that contribute to the greenhouse effect and global warming. The main greenhouse gases are:
- Carbon dioxide (CO2)
- Methane (CH4)
- Nitrous oxide (N2O)
- Fluorinated gases (hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, nitrogen trifluoride)
How are total GHG emissions calculated?
Total GHG emissions are calculated by converting the emissions of each greenhouse gas into their carbon dioxide equivalent (CO2e) using their global warming potential (GWP). This allows the different gases to be combined into a single number.
The calculation involves:
- Measuring the emissions of each GHG from different sources (in tonnes)
- Multiplying the emissions by the GWP of each gas to convert to CO2e
- Summing the CO2e values to arrive at total GHG emissions
For example, methane has a GWP of 25 over 100 years. This means 1 tonne of methane has the same global warming impact as 25 tonnes of CO2.
Accurately tracking total emissions allows organizations to identify major emission sources, set reduction targets, and track progress over time. Various international standards like the GHG Protocol provide detailed guidelines on emission calculations.
How do you calculate GHG emissions?
The most common method used to calculate GHG emissions is the Tier 1 Calculation Method:
GHG emission = 0.001 * Fuel Usage * High heat value * Emission factor
You can source these values from the EPA's GHG Reporting Program (GHGRP) documentation and your own company records.
To break this formula down:
-
Fuel Usage refers to the amount of fuel combusted over a period of time. This is usually measured in natural units for that fuel such as kWh for electricity, liters for liquid fuel, cubic meters for gaseous fuel, metric tons for solid fuel, etc.
-
High Heat Value is the amount of heat released by the complete combustion of a unit quantity of fuel. Each type of fuel has a specific high heat value. Common values can be found in the EPA documentation.
-
Emission Factor is the average emission rate of a greenhouse gas for a given source relative to units of activity. It relates GHG emissions to a common metric, like fuel consumption. Emission factors are usually given in units of metric tons of CO2 equivalent per unit burnt.
So by inputting these variables into the Tier 1 equation, you can estimate your company's total GHG emissions for a given period. Just ensure you use the accurate activity data and appropriate emission factors for increased calculation accuracy.
What is the meaning of GHG emissions?
Greenhouse gases (GHGs) like carbon dioxide, methane, and nitrous oxide trap heat in the atmosphere, causing global temperatures to rise. The total amount of these heat-trapping emissions released into the atmosphere is referred to as total greenhouse gas (GHG) emissions.
Total GHG emissions are often measured in tonnes of carbon dioxide equivalent (tCO2e) over a specific timeframe, providing a standardized way to quantify and compare emissions from different greenhouse gases. Tracking total emissions helps governments, companies, and individuals understand their overall climate impact and set science-based emissions reduction targets.
With rising global GHG emissions driving climate change, many countries and corporations have pledged to achieve net-zero total emissions by 2050. This means reducing total emissions as much as possible and balancing out any remaining emissions, for example, by investing in carbon removal projects. For small and medium-sized enterprises on the path to net-zero, measuring total GHG emissions is an essential first step to managing and lowering climate impacts.
What is the total US GHG emissions per year?
The total greenhouse gas (GHG) emissions in the United States was approximately 6.6 billion metric tons of carbon dioxide equivalent (CO2e) in 2019. This represents all anthropogenic emissions from sources across the American economy, spanning carbon dioxide, methane, nitrous oxide, and fluorinated gases.
The Environmental Protection Agency provides annual estimates of national GHG emissions across economic sectors. The latest EPA data on U.S. GHG emissions reveals key trends:
- Emissions peaked in 2007 at around 7.4 billion metric tons CO2e and have generally declined over the past decade.
- The three largest emitting sectors consist of electricity production (25% of 2019 emissions), transportation (29%), and industry (23%).
- Within industry, the largest sources of emissions include fossil fuel extraction, chemical production, mining, and waste management.
- Methane emissions account for 11% of total U.S. GHGs, largely stemming from enteric fermentation from livestock, natural gas systems, and landfills.
Reducing national GHG emissions remains a pressing issue, with international commitments requiring the U.S. to cut emissions by 50-52% below 2005 levels by 2030. Successfully navigating emissions mitigation strategies across economic sectors will be vital in meeting reduction targets.
Assessing Your Company's GHG Emissions: A Global Perspective
As an SME seeking to reduce your total greenhouse gas (GHG) emissions, it's important to first gain an accurate understanding of your company's carbon footprint. This involves measuring emissions generated across your entire value chain, from raw material extraction to product end-of-life.
While complex, measuring total emissions is essential for benchmarking, goal-setting, and identifying effective reduction opportunities. It also allows you to understand your impact in a global context compared to country and sector averages.
Total GHG Emissions by Country: Understanding Your Geographic Impact
When assessing total emissions, it helps to examine profiles of the countries where you operate. This geographic breakdown offers insights into:
- Policy landscapes and reduction targets
- Grid electricity emissions factors
- Popular reduction strategies and innovations
For example, if your company operates facilities in the United Kingdom and India, you'd benchmark against:
-
UK: Legally binding 80% reduction target by 2050. Grid is low-carbon intensive but costs are high. Popular strategies involve renewable electricity procurement, electric vehicles, and energy efficiency.
-
India: Voluntary 33-35% reduction target by 2030. Grid is highly carbon-intensive but costs are low. Popular strategies involve on-site solar, clean cooking stoves, and methane capture/use.
Understanding these differences allows you to contextualize your footprint and identify region-specific reduction opportunities.
Evaluating Emissions by Source: A Detailed Approach
Beyond country-level insights, it's critical to evaluate emissions at the source level within your company's own operations and value chain. This granular quantification and classification is the foundation for making informed reduction decisions.
As outlined in the Greenhouse Gas Protocol, assess emissions produced during:
- Raw material extraction/sourcing
- Transportation/distribution
- Manufacturing processes
- Electricity usage
- Waste disposal
Pinpointing high-impact sources shows where you can achieve the greatest emission cuts per dollar spent. It also prevents underestimating your total footprint.
Common sources with outsized impacts include:
-
Energy Intensive Manufacturing: Emissions from fuel combustion during metal production can account for over 50% of a manufacturer's footprint.
-
Deforestation: Forest conversion for raw material sourcing like palm oil emits tons of stored CO2.
Get granular with your emissions accounting before developing reduction plans. Identify what resources and processes drive your footprint, allowing customization of cost-effective abatement strategies.

Dissecting Global Greenhouse Gas Emissions by Sector
Analyzing industry-specific emission data to understand where SMEs fit within the broader picture of sector emissions.
IPCC Emissions by Sector: Mapping Your Industry's Footprint
The Intergovernmental Panel on Climate Change (IPCC) provides comprehensive global greenhouse gas (GHG) emissions data broken down by economic sector. This allows SMEs to benchmark their emissions footprint against industry averages.
For example, if you operate in the transportation sector, IPCC data shows it accounts for 14% of global emissions. This context helps transportation companies set science-based emissions reductions in line with decarbonizing the broader sector. Specific goals might include:
- Reduce scope 1 and 2 emissions 30% by 2025 and 80% by 2050 compared to a 2015 baseline
- Work towards a net-zero emissions transportation fleet by 2040
Having sector-specific reduction targets keeps companies accountable to their peer group by ensuring they decarbonize at least as quickly as industry averages. Failing to act could mean falling behind.
CO2 Emissions by Source: Focusing on the Main Culprits
While transportation produces significant quantities of nitrous oxide and methane, CO2 makes up the largest share of GHG emissions from burning fossil fuels. An effective emissions reduction strategy targets your company's biggest CO2 emission sources first.
Data from the IPCC shows power generation causes over 40% of global CO2 emissions. For an SME, this insight means prioritizing interventions like:
- Switching to renewable energy sources to eliminate scope 2 emissions
- Improving equipment and building energy efficiency
- Electrifying vehicles/machinery that still rely on fossil fuels
Taking aim at your top sources of carbon dioxide emissions will net the largest, swiftest reductions. Pair this with offsetting any remaining unavoidable emissions and your company can reach net-zero total GHG emissions faster.
Implementing Impactful GHG Reduction Strategies
Reducing greenhouse gas (GHG) emissions is a complex yet crucial undertaking for small and medium-sized enterprises (SMEs) on the path to net-zero. Operational changes, supply chain adjustments, and technology upgrades can have a significant impact. Here are effective GHG reduction strategies SMEs can implement.
Leveraging Green Tech to Cut Emissions at the Source
Transitioning to renewable energy sources and investing in energy-efficient equipment are impactful ways SMEs can reduce emissions.
Some technology upgrades to consider:
- Install solar panels or wind turbines to power operations through renewable energy. Government incentives like tax credits or rebates can improve ROI.
- Switch to LED lighting and motion sensors to lower electricity usage. Smart lighting systems allow remote control over usage as well.
- Replace old HVAC systems with high-efficiency heat pumps to lower natural gas and heating oil consumption. Newer models can reduce related emissions significantly.
- Improve process heating systems, ovens, furnaces and boilers by installing waste heat recovery technology to repurpose excess heat.
- Invest in hybrid vehicles, electric fleet vehicles, and EV charging stations to transition fleet operations away from fossil fuels.
Small process improvements can also minimize waste and emissions:
- Set all computers, monitors, printers and copiers to energy saver/sleep mode when not in use.
- Adjust refrigerator temperatures, hot water heaters, pool heaters, and other equipment to operate efficiently without compromising performance.
- Encourage employees to switch off lights, electrical equipment, and appliances when not required or during inactive hours.
Supplier Engagement: Spurring Industry-Wide Emission Reductions
SMEs can significantly influence their upstream and downstream supply chain partners to adopt sustainable best practices. Supplier engagement helps drive emission reductions industry-wide.
Strategies for supply chain engagement include:
- Survey suppliers about their carbon footprints and emission reductions plans. Prioritize partners committed to sustainability.
- Include contract clauses mandating climate action from suppliers to spur change. Terms may require disclosing and lowering emissions over time.
- Offer financial incentives for suppliers meeting sustainability criteria related to operations, manufacturing or distribution.
- Highlight partner sustainability commitments in marketing materials and social media when ethically sourced or environmentally-friendly.
Driving cross-industry GHG reductions through standards development also helps. Joining industry groups helps set emissions benchmarks and technology standards for entire sectors. Shared research, case studies and pilot projects further collective progress.
Total GHG emissions can feel like an expansive challenge. However, every small step when multiplied across many SMEs adds up to meaningful progress. Implementing even a few of these operational upgrades, process changes and supplier engagement strategies can significantly lower emissions.
Achieving Compliance: The Role of Carbon Offsets
As SMEs work to reduce their total GHG emissions, carbon offsets have emerged as an important tool for balancing unavoidable emissions while working towards compliance. Offsets fund external projects that reduce or avoid emissions, effectively counterbalancing the impact of a company's own footprint. When integrated thoughtfully into a comprehensive climate strategy, high-quality offsets can help SMEs achieve interim emission targets on the path towards net-zero.
However, offsets on their own are not a silver bullet. Companies must also aggressively reduce their own internal emissions through improved energy efficiency, renewable energy sourcing, supply chain transformations, and other decarbonization efforts. Offsets complement these initiatives, helping to neutralize remaining unavoidable emissions in the short term while internal reductions ramp up.
Balancing Act: When and How to Use Carbon Offsets
Rather than view offsets as a free pass to continue emitting GHGs indefinitely, SMEs should establish science-based targets for reducing their own emissions in line with 1.5°C pathways. Offsets can then help counterbalance residual emissions they cannot immediately avoid or reduce. As internal reductions accelerate over time, companies can decrease their reliance on offsets.
When integrating offsets, SMEs should prioritize funding projects that also confer co-benefits beyond pure emission reductions. For example, offsets that prevent deforestation or deploy renewable energy in developing regions can better align with ethical sourcing and social responsibility goals.
SMEs should also beware of over-relying on cheap, low-quality offsets that lack integrity. More reputable offsets verified by recognized standards often come at a higher price - but help ensure actual, permanent emission reductions are achieved. Quality can matter more than quantity when it comes to offset claims.
Ensuring the Integrity of Offset Projects
With growing scrutiny of offset programs, SMEs must vet projects thoroughly before purchase to guarantee real emissions are reduced. Key factors to examine include:
-
Additionality: Would the project have happened anyway without offset funding? True additional projects go beyond "business as usual" activities.
-
Permanence: Are emission reductions long-lasting and irreversible? Some offsets carry risk of reversals, ie. future deforestation of conserved forests.
-
Leakage: Does the project inadvertently increase emissions elsewhere? Stopping deforestation in one area could displace loggers towards new forests.
-
Double counting: Have the same reductions been counted or sold by multiple parties? Robust registries prevent double claiming.
-
Co-benefits: What social or ecological benefits does the project confer beyond GHG reductions? Co-benefits indicate higher quality projects.
By selecting offsets verified under recognized standards like Gold Standard or VCS, SMEs can ensure their climate investments actually enable emission reductions across the global economy - not just on paper. These high-quality offsets serve as a credible bridge as SMEs work to transform their own operations and supply chains for a net-zero future.
Benchmarking and Showcasing Reductions: Greenhouse Gas Emissions by Country Percentage
The importance of tracking and publicly reporting on emission reductions, showcasing efforts in relation to country-specific achievements.
Setting the Bar: Comparing Emission Reductions to National Averages
SMEs can utilize publicly available data on national greenhouse gas (GHG) emissions to benchmark their own reduction efforts. For example, if an SME operates mainly in the United States, it could compare its percentage decrease in emissions to the US national average reduction.
Displaying GHG cuts in relation to country averages helps showcase the meaningfulness of SME actions. Rather than presenting emission numbers devoid of context, the percentages provide a reference point for stakeholders to understand performance.
An SME that has reduced emissions by 20% while the US national average is 10%, demonstrates exceptional leadership. Comparing to national data enables constructive conversations around goal-setting and recognizing sustainability achievements.
Cultivating a Culture of Transparency and Accountability
Publicly sharing GHG emission percentages over time cultivates a culture of transparency and accountability around sustainability. Software tools like EcoHedge Lifecycle simplify annual tracking and reporting to highlight trends.
Displaying decreasing total GHG emissions openly, measured as per Greenhouse Gas Protocol sector-based methodologies, builds trust and credibility with stakeholders. Investors can clearly track emission trajectory while customers and employees gain confidence in the seriousness of efforts.
Transparent communication removes skepticism around actual climate action taking place. Backing percentage-based reduction claims with verifiable data enables accountability and progress.
SMEs serious about achieving net zero should not shy away from honest conversations around emission percentages changing over time. Openness drives engagement and surfaces opportunities for further emission cuts.
Future-Proofing: Preparing for Evolving Regulations and Market Dynamics
As regulations and market dynamics related to greenhouse gas (GHG) emissions continue to evolve, small and medium-sized enterprises (SMEs) need strategies to future-proof their business. By staying abreast of emerging regulations and anticipating the implications of carbon pricing mechanisms, SMEs can adapt their operations for long-term resiliency.
Adapting to the Regulatory Landscape: Insights for SMEs
With many governments implementing policies to reach net-zero emissions targets, SMEs should understand how emerging regulations might impact their business. Some key insights include:
- Monitor government announcements and industry publications to stay updated on regulatory changes. Setting Google News alerts or subscribing to newsletters can help.
- Perform a gap analysis to identify areas where your company emissions reporting and reduction plans may not meet future compliance standards.
- Seek input from legal and sustainability advisors on interpreting complex regulatory terminology or planning adaptation strategies. Their expertise can prove invaluable.
- Evaluate business processes to find efficiencies that reduce emissions and costs simultaneously, facilitating adaptation. For example, installing sensors and using data analytics to optimize energy and resource use. - Consider sustainability certifications like B Corp or Science Based Targets to verify your credible climate action for stakeholders.
Adjusting operations ahead of new regulations coming into force will allow SMEs to avoid penalties, safeguard growth opportunities, and reinforce their reputation as a responsible business.
Forecasting the Financial Implications of Carbon Markets
As more jurisdictions adopt carbon pricing policies, SMEs need to assess how these could affect operational expenses and revenue:
- Use online carbon pricing calculators to forecast added costs from carbon taxes or trading schemes based on your company's emissions and energy mix.
- Model different pricing scenarios — both current prices and projected future prices set to rise steeply. This shows potential cost curves your business could experience.
- Research if your industry will receive emission allowance allocations or tax relief to offset rising carbon costs. For example, policies often shield emissions-intensive, trade-exposed industries.
- Consider revenue opportunities by monetizing approved carbon credits from your own reduction projects or supplying goods and services to help other companies lower emissions.
- Seek energy audit and financial analysis assistance from government-backed sustainability advisors to evaluate decarbonization investments specific to your company. From more efficient equipment to rooftop solar panels, these projects can deliver attractive returns while cutting tax liabilities.
Proactively assessing the bottom-line impacts of evolving carbon regulations and markets allows SMEs to make strategic investment decisions that buffer them from rising costs and unlock new revenue streams on the path to decarbonization.
