EV Carbon Credit Calculator
Instructions:
To calculate carbon credits based on total energy consumption in kilowatt-hours (kWh), you’ll typically need to use the following formula:
Determine Total Energy Consumed (kWh): This is usually measured by summing the energy usage over a specific period, which can be obtained from utility bills or energy meters.
Calculate Carbon Emissions (kg CO2): Multiply the total energy consumed by the emission factor of the energy source. The emission factor is usually given in kg CO2 per kWh and varies depending on whether the energy comes from coal, natural gas, renewables, etc.
Carbon Emissions (kg CO2)=Total Energy Consumed (kWh)×Emission Factor (kg CO2/kWh)
Calculate Carbon Credits: If applicable, convert the carbon emissions into carbon credits. This step may involve determining how the reduction of emissions translates into credits based on specific carbon credit standards or programs.
– CC = Carbon Credits (in metric tonnes of CO2 equivalent)
– BE = Baseline Emissions (emissions that would have occurred without the project)
– PE = Project Emissions (emissions resulting from the EV charging activity)
Baseline Emissions (BE) refers to the emissions related to the fuel usage of conventional internal combustion engine vehicles (ICEVs).
Formula: BE = Distance x Emission Factor (EF)
Where: Distance = Total distance traveled by EVs due to charging activity (in km).
(EF) = Emission factor for ICEV (in kg CO2 per km)
Project Emissions (PE): represents the emissions from the electricity consumed by EV chargers.
Formula: PE = Energy (E) x Grid Emission Factor (GEF)
Where: Energy (E) = Total energy used by the EV charger (in kWh). GEF = Grid Emission Factor (in kg CO2 per kWh, varies by electricity grid region)
Energy (E): = Power Rating (P) x Time of Usage (T)
Where: Power Rating (P) = Charger power in kW. Time Usage (T) = Total hours charger is in use.
The carbon credits are quantified by subtracting PE from BE, reflecting the net reduction in emissions.
Calculate Carbon Credits
To calculate carbon credits, start by determining the Baseline Emissions (BE) – the expected emissions without your project. Measure the actual Project Emissions (PE) post-implementation and subtract this from the Baseline Emissions to get the Emission Reductions (ER). The formula is simple:
CC=BE−PE
ICE Vehicle Impact Calculations
(ICE kg C02 per kWh)
To calculate the emissions from an internal combustion engine (ICE) vehicle in terms of kg CO2 per kWh, you’ll need to follow these steps:
Determine Fuel Consumption (liters or gallons): This can be obtained from fuel efficiency ratings (e.g., liters per 100 km or miles per gallon) and the total distance traveled.
Calculate Energy Content of Fuel: Use the energy content of the fuel to convert the volume consumed into energy. For gasoline, this is approximately 34.2 MJ/liter, and for diesel, it’s about 38.6 MJ/liter.
Calculation: Energy Consumed (kWh) =
Fuel Volume (liters)×Energy Content (MJ/liter)/3.6
Determine Emission Factor for Fuel: Use the emission factor, typically around 2.31 kg CO2/liter for gasoline and 2.68 kg CO2/liter for diesel.
Calculate Total Emissions (kg CO2):
Total Emissions (kg CO2)=Fuel Volume (liters)×Emission Factor (kg CO2/liter)
Calculate Emissions per kWh:
Emissions (kg CO2/kWh) =
Total Emissions (kg CO2) Divided by (/) Energy Consumed (kWh)
