As the world becomes increasingly aware of the impact of carbon emissions on the environment, it is essential to understand the different types of emissions and their sources. When it comes to transportation, two types of vehicles dominate the market - electric vehicles (EVs) and gasoline vehicles. While EVs are considered to be environmentally friendly, their scope 3 emissions also need to be taken into account.
Scope 3 emissions refer to all indirect emissions that occur in the value chain of a product or service, including the extraction of raw materials, manufacturing, distribution, and disposal. In the case of electric vehicles, the majority of their scope 3 emissions come from the production of the battery, which involves the extraction of minerals such as lithium, nickel, and cobalt.
According to a study conducted by the International Council on Clean Transportation (ICCT), the production of an average electric vehicle battery pack results in around 75-150 kg of CO2e emissions per kWh of storage capacity. This means that a 60 kWh battery would generate between 4.5 to 9 tonnes of CO2e emissions.
However, it is worth noting that the emissions from battery production are one-time emissions and are spread over the life of the vehicle. In contrast, gasoline vehicles emit carbon emissions continuously throughout their lifespan, from the extraction of crude oil to the burning of gasoline in the engine.
According to the Environmental Protection Agency (EPA), a typical gasoline vehicle emits around 4.6 metric tons of CO2e per year. This means that a gasoline vehicle emitting this amount of CO2e will produce the same amount of emissions as an electric vehicle with a 60 kWh battery after 4-8 years of use.
It is also important to note that the scope 3 emissions of electric vehicles can vary depending on the source of electricity used to charge them. If the electricity comes from renewable sources such as wind or solar, the emissions will be significantly lower than if the electricity is generated from coal or natural gas.
In conclusion, both electric and gasoline vehicles have scope 3 emissions that need to be taken into account. However, the emissions from battery production are one-time emissions, while gasoline vehicles emit continuously throughout their lifespan. Therefore, while electric vehicles have a higher initial carbon footprint, they become more environmentally friendly over time as the emissions from battery production are spread out over the life of the vehicle.
KEY TAKEAWAYS:
- Scope 3 emissions refer to all indirect emissions that occur in the value chain of a product or service, including the extraction of raw materials, manufacturing, distribution, and disposal.
- Electric vehicles (EVs) have higher scope 3 emissions from the production of their battery, which involves the extraction of minerals such as lithium, nickel, and cobalt.
- Gasoline vehicles emit carbon emissions continuously throughout their lifespan, from the extraction of crude oil to the burning of gasoline in the engine.
- The emissions from battery production for EVs are one-time emissions, while gasoline vehicles emit continuously throughout their lifespan.
- The scope 3 emissions of electric vehicles can vary depending on the source of electricity used to charge them.
- EVs have a higher initial carbon footprint but become more environmentally friendly over time as the emissions from battery production are spread out over the life of the vehicle.
- It is important to take into account both the scope 3 emissions of electric and gasoline vehicles when considering their environmental impact.
