Carbon emissions are on the international scope. Experts have warned us for decades that inaction will lead to drastic hunger levels, mass migration due to flooding, the collapse of financial markets and many more socio-economic disasters. If businesses were anxious about COVID-19, climate change will give them goosebumps. That is why leaders and executives are now increasing their attention to sustainability, and reviewing their mission and purpose. Sustainability is a business imperative, and should not be considered as a mere component of corporate social responsibility.
Businesses must reduce their environmental impact. One of the most significant ways to do this is by reducing their carbon footprint, and this starts with monitoring carbon emissions. Our comprehensive guide explains emission scopes 1, 2 & 3 (as defined by the GHG Protocol), and how Plan A helps companies become carbon neutral.
Reducing carbon emissions is a business imperative
Recent announcements from GAFA and other major companies show how significant carbon footprints have become for businesses. Apple, for example, has committed to making its supply chain carbon-neutral by 2030. Nine other huge companies (inc. Starbucks, Microsoft, Unilever, Nike) are founders of Transform to Net Zero, with the mission to accelerate the transition to a net-zero carbon economy.
The fact is, carbon emissions are responsible for 81% of overall GHG emissions, and businesses are responsible for a lot of it. The rest of GHG emissions are: methane (10%), nitrous oxide (7%) and fluorinated gases (3%). Businesses must monitor and report their CO2 emissions, which is the key first step in reducing them. To do so, companies must classify their carbon footprint in three scopes.

Explained: Scope 1, 2 & 3 emissions
According to the leading GHG Protocol corporate standard, a company’s greenhouse gas emissions are classified into three scopes. Scope 1 and 2 are mandatory to report, whereas scope 3 is voluntary and the hardest to monitor. However, companies succeeding in reporting all three scopes will gain a sustainable competitive advantage.
Scope 1: direct emissions
Scope 1 emissions are direct emissions from company-owned and controlled resources. In other words, emissions are released into the atmosphere as a direct result of a set of activities, at a firm level. It is divided into four categories: stationary combustion (e.g fuels, heating sources). All fuels that produce GHG emissions must be included in scope 1.
Then, mobile combustion is all vehicles owned or controlled by a firm, burning fuel (e.g. cars, vans, trucks). The increasing use of “electric” vehicles (EVs), means that some of the organization fleets could fall into Scope 2 emissions.
Fugitive emissions are leaks from greenhouse gases (e.g. refrigeration, air conditioning units). It is important to note that refrigerant gases are a thousand times more dangerous than CO2 emissions. Companies are encouraged to report these emissions.
Process emissions are released during industrial processes, and on-site manufacturing (e.g. production of CO2 during cement manufacturing, factory fumes, chemicals).
Scope 2: indirect emissions – owned
Scope 2 emissions are indirect emissions from the generation of purchased energy, from a utility provider. In other words, all GHG emissions released in the atmosphere, from the consumption of purchased electricity, steam, heat and cooling.
For most organizations, electricity will be the unique source of scope 2 emissions. Simply stated, the energy consumed falls into two scopes: Scope 2 covers the electricity consumed by the end-user. Scope 3 covers the energy used by the utilities during transmission and distribution (T&D losses).
Scope 3: indirect emissions – not owned
Read this paragraph carefully as scope 3 emissions represent the holy grail of emissions.
Scope 3 emissions are all indirect emissions – not included in scope 2 – that occur in the value chain of the reporting company, including both upstream and downstream emissions. In other words, emissions are linked to the company’s operations. According to GHG protocol, scope 3 emissions are separated into 15 categories.
Upstream activities fall under several categories: for many companies, business travel is one of the most significant to report (e.g. air travel, rail, underground and light rail, taxis, buses and business mileage using private vehicles). Also, employee commuting shall be reported, as it results from the emissions emitted through travel to and from work. It can be decreased through public transportation and home office.
Waste generated in operations relates to waste sent to landfills and wastewater treatments. Waste disposal emits methane (CH4) and nitrous oxide (N2O), which cause greater damage than CO2 emissions.
Purchased goods and services, includes all the upstream (‘cradle to gate’) emissions from the production of goods and services purchased by the company in the same year. It is useful to differentiate between purchases of production-related products (e.g, materials, components and parts) and non-production-related products (e.g, office furniture, office supplies and IT support).
Transportation and distribution occur in upstream (suppliers) and downstream (customers) elements of the value chain. It includes emissions from transportation by land, sea and air, as well as emissions relating to third-party warehousing.
Fuel and energy-related activities include emissions relating to the production of fuels and energy purchased and consumed by the reporting company, in the reporting year that is not included in scope 1 and 2.
Capital goods are final products that have an extended life and are used by the company to manufacture a product, provide a service or, store, sell and deliver merchandise. Examples of capital goods include buildings, vehicles, machinery. For purposes of accounting for scope 3 emissions, companies should not depreciate, discount, or amortize the emissions from the production of capital goods over time. Instead, companies should account for the total cradle-to-gate emissions of purchased capital goods in the year of acquisition (GHG protocol).
Investments are included largely for financial institutions, but other organisations can still integrate it into their reporting. According to GHG accounting, investments fall under 4 categories: equity investments, debt investments, project finance, managed investments and client services.
Franchises are businesses operating under a licence to sell or distribute another company’s goods or services within a certain location. Franchisees (e.g. companies that operate franchises and pay a fee to the franchisor) should include emissions, from operations under their control. “Franchisees may optionally report upstream scope 3 emissions associated with the franchisor’s operations (i.e., the scope 1 and scope 2 emissions of the franchisor) in category 1 (Purchased goods and services).”
Leased assets correspond to leased assets by the reporting organisation (upstream) and assets to other organisations (downstream). The calculation method is complex and shall be reported in scope 1 or 2, depending on the nature of the leased asset.
Used of sold products is included, concerning “in-use” products that are sold to the consumers. It measures the emissions resulting from product usage, even if it varies considerably. For example, the use of an iPhone will take many years to equal the emissions emitted during production.
At the same time, “end of life treatment” corresponds to products sold to consumers, and is reported similarly as “waste generated during operations”. Companies must assess how their products are disposed of, which can be difficult as it usually depends on the consumer. This encourages firms to design recyclable products that limit landfill disposal.
Why measure all 3 scopes?
More often than not, emissions along the value chain represent the biggest GHG impact. For decades, companies have missed significant opportunities for improvement. For example, Kraft Foods reported that 90% of its total emissions, fell under its value chain (cf. scope 3). Finally, companies must conduct a full GHG emission inventory – scope 1, 2 and 3 – to focus their efforts on reducing carbon emissions, carbon footprint and becoming carbon-neutral.
Reporting and reducing carbon emissions is time-consuming, challenging and deserves close expertise. Plan A offers unique tools to reduce your carbon emissions, per scope. Become carbon neutral by requesting a free demo.
