Carbon Accounting for Companies and Organizations

With the overwhelming evidence that energy crises play a role in global warming, most organizations that subscribe to the sustainability ethos do not leave carbon accounting to chance but rather embrace it, considering the fact that it forms part of compliance with the laws and corporate ethics.

» Carbon Accounting Framework for Companies and Organizations

Introduction

It is impossible to imagine a company thinking only about regulatory requirements when one thinks about the planning process of carbon accounting. The purpose of these quantifications is to enable organisations to understand their major emissions contributing factors, and set targets for reducing them and come up with practical initiatives towards this end. Notably, carbon accounting has its importance, especially, in enhancing the level of transparency among the companies in terms of how each corporate is able to report its impacts on climate change to the various stakeholders such as financiers, consumers, and even the government.

Accounting and Reporting Principles

The most conventional reaction to green-house emissions estimation is careful balancing – accuracy, transparency, cost. Also it encourages involvement in projects aiming at mitigation of GHG, improving the coherence between firms. Green House Gas account particular activities include:
Relevance: The appropriate delineation of the company’s border ensures that the  inventories can be adequately meaning designed for the users of such inventories in terms of the decisions to be made
Completeness: With regards to completeness, all and any sources of GHG emissions as identified within a particular boundary are expressed as an exhaust profile.
Consistency: The procedures remain the same when comparing different times for the sake of generating meaningful data.
Transparency: Assumptions, practices, and limitations regarding the data are gasification of a collecting content of the methodologies.
Accuracy: Minimizing errors and where data concerning emissions is neither exaggerated nor under estimated.

Business Goals and Inventory Design

The greenhouse gas inventories are prepared by corporate bodies for a variety of strategic purposes, including mitigation of climate change, performance monitoring, monitoring and supporting suppliers and customers and differentiation of products in the market. This is because, by aligning the greenhouse gas inventory with those strategic goals, businesses manage climate risks, stay sustainable, work on engagement with supply chains and even compete on products.

Setting Organizational and Operational Boundaries

It is necessary to clarify the organizational and operational boundaries when dealing with GHG accounting to understand the boundaries of emission in inclusion within the inventory.
Organizational Boundaries refer to the boundaries that an organization can take using either the equity share approach where the emissions are counted in terms of the percentage shares owned or the control approach covering all financial or operational controlled emissions.
Operational Boundaries are defined as those marking the source of emissions, which are all inclusive of Scope 1, covering all direct emissions, Scope 2 accounting for indirect emissions caused due to the purchase of electricity and lastly Scope 3 covering all other sources of emissions from the company in the correct context of emission (outlook).

Tracking Emissions Over Time

Maintaining consistency in tracking emissions during the different time periods is necessary for the effective evaluation of GHG mitigation measures and compliance with the regulations in force. Organizations may set base year targets for comparison, structural/marketing changes, and related uncertainties. Also important for measuring interference of emissions data and how far the stages in meeting the GHG reduction goals have come.

Allocating Emissions

Allocation must be done when a source of input or emissions is common for more than one product or process in the Carbon credit analysis. Organizations have options for dissolution of the boundary of allocation – through disaggregating the processes or through building a larger system that supplements with alternative processes; however, if the allocation is needed it may be carried out as either on the basis of physical quantities (in terms of mass and volume) or on possession and wealth. Another area where allocation of burdens considers factors such as the energy expenditure and the advantages to the environment is Recycling. Clear and understandable allocation principles are first steps towards gaining confidence and respect from various stakeholders.

Challenges in Carbon Accounting

Carbon accounting is useful and has various benefits, but at the same time it equally has challenges. However, obtaining accurate data for Scope 3 emissions is somehow not that easy and simple and may be very expensive. Apart from that, a few structures do not have definite standards making it difficult to report such emission type. In order for companies to deal with these challenges, and make sure that their carbon accounting exercise is precise, thorough, they must have such systems and procedures fully implemented.

» Carbon Accounting Methods for Companies and Organizations

A cradle-to-grave or life cycle approach of greenhouse gases accounting is a useful requirement in order to evaluate the goal concerning impacts of a product. In a life cycle assessment (LCA), all steps of the product life cycle are assessed, from the acquisition of raw materials to the production and consumption, distribution, the use of such product and then to its final disposal. Doing so allows organizations to focus in on the greatest emission sources for mitigation.

Defining Life Cycle Stages

Key life cycle stages include:

Raw Material Acquisition This sub-stage is comprised of the activities related to extraction and preparation of the raw materials required in the manufacture.

Manufacturing This involves the operations in which the raw materials are converted to a finished product and the assembled product is packed.

Distribution and Retail This stage refers to the movement of a good until its point of sale.

Use This sectional analysis looks at the emissions during the productive use of the goods, particularly energy use.

End-of-Life This includes disposal of the product, and, where necessary, recycling and reuse of such products.

Attributional Approach to GHG Inventory – Every technique accepted for GHG product life cycle accounting is the extraction based one and does not allow the concepts of GHGs are accounted for. The attributional approach links emissions solely to specific processes, or phases, of a product’s lifecycle to facilitate emission measurements and reports. The lattice addresses angles such as the relative effectiveness of different products, and changes in emissions over a certain period of time.
Establishing the Scope of a Product Inventory – It is clearly important to define the scale of a GHG inventory for a specific product. The scope gives parameters of what is going to be covered in the inventory, for example, what processes, what activities, and what emission sources will be taken into account. It is all about the very product and for that matter, the level of detail in the inventory should describe the product, along with explaining the units of analysis and the reference flow. The limits should include all the stages of life, and ensure that all key sources of emissions are captured.

Data Collection

Collecting data is essential for greenhouse gas emission measurement. The first preference is given to primary data, directly taken and measured from the processes of the company as they are more accurate. If there is no primary data, secondary data can be taken from external, credible sources. The data must therefore be aptly collated, documented and this is accompanied by extensive quality assessment in terms of accuracy, completeness, consistency, relevance and transparency.

Identifying and Measuring the Emissions

Emissions accounting concerns, firstly, the assessment and inventory of emissions that the corporation manages and would like to cut back. This action involves the scopes, which are the mechanisms to categorize emissions by sources and controls. Knowing what these scopes are and the respective methods of quantification of emissions is necessary in order to achieve effective reporting and emission control.

Scope 1: Direct emissions from owned or controlled sources (e.g., fuel combustion)

Scope 1 Emissions relate to the greenhouse gas management hierarchy as the lowest, most easily avoidable part of the overall company’s inventory GHG structure. Greenhouse gases released under emissions winding up in this scope for the specific company are mostly due to direct activity. Additionally, the scope 1 emissions can be presented in several ways:

Stationary Combustion: Most probably, emissions from stationary combustion are released as a result of the burning of fossil fuels and biomass in structures that are immobile such as boilers, heaters or turbines within the facilities in question. The main emissions produced are those of carbon dioxide (CO2) but after that, also includes other gases such as methane (CH4) and nitrous oxide (N2O) which varies with the fuel mix and the purpose of burning of fuels. Factors are utilized to determine the amount of emissions per unit fuel displaced or used i.e. multiplying the amount of fuel multiplied with an emission factor which means the carbon dioxide emitted in combustion of unit fuel.

Mobile Combustion: Mobile combustion refers to emissions as a result of use of fuels especially in transport due to ownership or operations of vehicles such as vans, trucks, jet planes or ships among others. Just as in stationary combustion, carbon dioxide is the main greenhouse gas that is emitted, in addition to methane and nitrous oxide. Emissions from vehicles are calculated through metricatings of fuel used in those vehicles although mileage data or even the time used may also help.

Process Emissions: Process emissions do not arise due as a result as chemical and industrial processes due to chemical reactions. These industries include among others component production (cement), non ferrous (aluminum), chemicals (manufacturing). For instance, in clinkering that of cement, or in kiln operations calcination of the limestone, usually there is a release of carbon doxide. Solemnity of the emissions is determined either by chemical equation balance steps, operating details, or where applicable and direct considering practicality, measuring.

Fugitive Emissions: Fugitive emissions is understood to be the accidental escape of gases due to leakage or evaporation as well as other unintentional discharges from tooling or the infrastructure. These emissions are important in the operations which involve gases and liquids such as oil and gas production, cooling and conditioning. Examples of such include methane emissions produced during natural gas operations and HFC emissions from fridge. The approach to estimating the emissions given involves application of rather standard emission factors in the industry for given equipment or processes.

Exclusions from Scope 1:

Biogenic CO2 Emissions: CO2 emissions resulting from burning biomass (e.g., wood, biofuels) do not fall under the Scope 1 category but rather must be accounted for under biogenic emissions as they are typically considered to be a part of the ecological carbon cycle that stems from the use of sustainable biomass.

Non-Kyoto GHGs: Other types of gases e.g. CFCs which cause emissions not regulated by the Kyoto Protocol are also not covered under Scope 1. Such emissions are however of considerable concern and businesses are advised to include and address them elsewhere.

Scope 2: Indirect emissions from purchased electricity, steam, heat, and cooling.

Scope 2 Emissions encompasses emissions that are indirect in nature and arise from bought electricity, steam, heat and cooling that the company uses up. The sources that cause these emissions are not within the confines of the company’s control or ownership such as a utility or an energy company; however, they are significant in view of emission regulation because the production of electricity for people accounts for a significant share of carbon dioxide and other greenhouse gasses emissions all over the world.

Calculation Methodology of Scope 2 Emissions lists out these categories of emissions based on the source of energy used which determines the operations and the suppliers chosen who supply that energy to the operations. This description enables firms to understand how well they are applying the mitigation options and improving their performance. Nevertheless, there are problems associated with Scope 2 estimation more so in the context of what to do with the procurement of renewable energy.

Key Challenges in Scope 2 Accounting

Renewable Energy Purchases: Corporations taken different tactics for measuring renewable energy consumption, resulting in inconsistencies within Scope 2 emissions accounting. Whilst some use estimates of emissions avoided, others on the contrary consider the purchase of renewable energy reaching zero emissions. How can purchases be honestly captured in Scope 2 inventory thus so this variation need to be addressed.

Instrument Challenges: Questions about issues such as what represents a renewable energy purchase, who projects supplier specific emission factors and how do regions and markets compare green power programs have been difficult.

Global Emissions Impact: It is still being debated whether green power programs result in actual GHG emissions reduction over the years and how these reductions should be included under Scope 2 emissions.

Scope 2 Accounting Methods

To address these challenges, companies use two key methods for Scope 2 emissions accounting:

Location-Based Method: This methodology is universal to every geographical area, and it is centered on the average intensity of emissions from the electricity grid that provides the power consumption. This encourages electricity demand among consumers and equates this particular demand to the level of emissions produced by a certain geographical area. All grids can utilize this method and it is especially helpful to determine the GHG levels of operating grids.

Market-Based Method: This methodology is wherever there is a free choice for the consumer regarding where to acquire the electricity or which product is to be used. It accounts for the input of CO2 from specifically chosen by firms electricity through contracts or energy attribute certificates such as renewable energy certificates (RECs). This approach is based on the understanding that such consumer behavior affects the energy market and promotes the use of clean energy.

Calculating Scope 2 Emissions

The process of calculating Scope 2 emissions involves several steps:

Identify Emission Sources: With respect to the facilities and operations within the organization that use electricity, steam, heat, or cooling, determine the sources of emissions.

Evaluate Market-Based Applicability: Determining whether the market based method is practical for any operation especially where companies have the freedom to choose electricity suppliers.

Collect Activity Data: This involves quantifying the amount of electricity, steam, heat, or cooling utilized within the reporting period one is looking at which is often done by utility bills, meter readings, or energy management systems.

Choose Emission Factors: The choice of emission factors for calculation is dependent on the approach taken for calculating (either location based method or market based method) each emission.

Match Emission Factors: With the compatible emission factors available, the relevant electricity units consumed are multiplied with the correct emissions reflective of the source and region/contract.

Calculate Emissions: Scope 2 emissions mentioned above are calculated by the activity levels against the corresponding emission factor and further adjusted where necessary for the Global Warming Potential values.

Aggregate Data: The total emissions for all relevant sites are calculated and presented under Scope 2 emissions for the entire organization.

Optional Reporting: Compute and include in a separate section such emissions as those that have been prevented ident way such as energy efficiency or renewables on site.

Scope 3: Other indirect emissions, including those from the production of purchased goods and services.

Scope 3 Emissions include all indirect emissions except those covered within Scope 1 and Scope 2 emissions that take place at lower or upper positions of the supply chain of a business and usually, the biggest part of the GHG emission fall in that category. So the relevant however and I turn descriptive methodology is also known as the Scope 3 standard, and about it, fuels the practicing companies to do the full carbon footprint of the organizations more precisely, so as to include gaps and optimize the processes using relevant data.

Scope 3 Categories

Scope 3 emissions are categorized into 15 distinct categories, covering a wide range of activities across the value chain:

Purchased Goods and Services: Embedded emissions from manufacturing of goods and services which have been purchased by the company.

Capital Goods: Supply of emissions that is due to the long-term assets. For instance, the heavy equipment and the infrastructure. 

Fuel- and Energy-Related Activities: Emissions that arise in the supply of fuel and power consumed by the organization, and the distribution of the same. 

Upstream Transportation and Distribution: Activity based emissions associated with transportation and distribution of items purchased by the organization. 

Waste Generated in Operations: Removal of waste emitted internally by the organization in the course of treating and disposing it of. 

Business Travel: Transport associated with employees travelling in the course of work. 

Employee Commuting: Emissions that caused by employees traveling from and back to their respective places of work. 

Upstream Leased Assets: Activity emissions from use of leased assets by the firm other than assets addressed in Scope 1 and Scope 2. 

Downstream Transportation and Distribution: Activity based emissions caused by transporting and distributing commodities marketed by an enterprise. 

Processing of Sold Products: Activity associated with emissions from fabrication of semi-finished goods from which income is generated by the organization.

Use of Sold Products: Emissions generated during the consumption of products and services the company provides.

End-of-Life Treatment of Sold Products: Emissions produced when products sold by the company reaches disposal.

Downstream Leased Assets: Emissions generated by assets that the company owns and lets the others to use.

Franchises: Emissions generated by the franchise businesses working with the company’s brand.

Investments: Emissions generated from other companies that the company invests in.

Managing Inventory Quality

​High-quality GHG data enables correct decisions and maintains stakeholder credibility as well as regulatory adherence. Developing any Inventory Quality Management System begins with Quality Control, which involves controlling the quality of data to meet certain standards of precision and accuracy, and advances to include Quality Assurance, which entails the review process, such as auditing. All actions, especially modes of collecting data, to including computing and writing reports, must be captured in one document, such as an Inventory Management Plan (IMP). To make sure that data is reliable, organizations uphold data collection standards that are clear and verification systems that are efficient. Analyzing and managing uncertainties requires evaluation, and evaluation involves optimizing and adapting the inventory mechanisms that are informed by the QA/QC, stakeholders’ opinions, and modern trends. This helps to keep the content of the inventory accurate, acknowledged and believable even into the foreseeable future.

» Carbon Accounting Reductions and Targets for Companies and Organizations

Reductions

Effective carbon management can be achieved by having a good and accurately accounting system for the GHG reductions as well as some reasonable and feasible goals. It is usually a particular activity done to the activities of reduction of the greenhouse gases during the business activities or as a consequence of working with the customers .There are two types of these reductions: the absolute reductions – a reduction of emissions which produces the same volume of activity, and the intensity reductions – or emissions per unit activity reduction. In this case to be able to measure them one of the most important things which has to be done is baselining or determining these reduction levels. Such comparisons are again in time or space performed by certain beliefs (reduction levels are always compared to a baseline emission level which they believe the situation would be). There is also important factor to clarify reporting techniques as well as this assumptions with external audits collecting activities conducted for purposes of reduction and reported reductions.

Setting Targets

Setting GHG targets is always essential for promoting advancement and coinciding the effort of a firm with radical sustainability goals. There are two main types of targets, namely: (I) absolute, which states the percentage decrease applied across the board within a period; and (II) intensity-based, which describes a reduction of carbon emissions in relation to the output produced. This involves a baseline assessment of the emissions at a given time and setting specific and measurable targets. Within this this context, it is necessary to have an action plan highlighting which measures will be taken for these targets and how these measures will be achieved; to regularly monitor progress which the targets against the KPIs. Transparent reporting of the purpose of the targets, the work done and even the impediments faced both facilitates accountability and long-term GHG emission reduction.

Verification of Emissions

​One of the most important steps in the preparation of GHG inventories is their verification. ‘Assurance’ refers to an external examination of an organization’s GHG inventory in respect of accuracy of the data and, in particular, methodologies and the manners of report presentation. It engenders confidence within relevant stakeholders, eases regulatory obligations and increases inventory dependability.

Levels of Assurance:

Limited Assurance only provides an evaluation in a condensed form as Verification and supervising are conducted and, as such, effect these items concerns major reasons only.

Reasonable Assurance, replaces that with a thorough examination and the renewing all of the stock that is more than Subject to count due to a greater grade of redundancy in assessment.

Assurance Providers:

First-Party Assurance involves the assessment procedures that are performed by the organization itself.

Second-Party Assurance involves assessment procedures that are performed in the interest of a company by some external party e.g. a holding company.

A different organization technology and management all in third party audit and this forms the most credible assurance; that is why this type is called Third-Party Assurance

The Assurance Process:

Planning, as the first step, includes the establishment of boundaries and the expectation of guidelines.

Data Collection and Review, in essence, is checking or amending data so that it is complete and accurate.

Site Visits, especially in the case of third-party audits, are conducted for the validation of data procedures performed.

The efficiency of GHG management of data is checked under the principles of Internal Controls Assessment.

Reporting introduces a report on the results, inconsistencies encountered, and makes suggestions on what might be done.

» Carbon Accounting Reporting for Companies and Organizations

Reporting Emissions

For any organization that implements carbon management, it is important to provide a complete, comprehensive GHG inventory report for clarity and openness. The structure of the report shall include, but not be limited to: general company data, definition of boundaries, information on data management, allocation and/or calculation methods used, and how uncertainties were dealt with. In a tabulated form, it must show total emissions as metric tons of carbon dioxide equivalency (CO2e) according to each life cycle as well as by each GHG, and also contain an assurance statement where this exists.

Besides these, there can be other optional sections in the reports that provide more specific information and illustrate commitment to sustainability on the part of the corporation. Amongst these sections could be GHG reduction targets with current progress, comparison with other corporates and additional information on the engagement of stakeholders to prove the consciousness of the organization in preserving the environment.

It should include an executive summary of the findings that is clear and concise for readers in general not economists and even non-specialists in the field. Further the data must be depicted in tables or figures, as detailed and relevant as possible, with concise narrative explanations to enable interpretation of the results within the firm’s overall emphasis on sustainability.

Finally, communicating inventory results in an appropriate format is crucial. Maintaining a separate approach to different stakeholders, for example, the investors, customers and regulators, helps to present the information in a clear, age specific manner that is interesting and refers to their own matters, while showing the company’s determination in reducing its carbon footprint and meeting sustainability goals.
