1. A. How to calculate CO₂ emissions

   CO₂ emissions can be calculated by following these steps.

   STEP1 through STEP4 and STEP6 are all required inputs for the calculation of CO₂ emissions.

   1. STEP1. Input Cargo Volume

      

      CO₂ emissions can be calculated by following these steps.

      Enter the actual gross weight in tonnes, kilograms, or the number of ocean containers and select a weight unit.

   2. STEP2. Select the Type of Transportation

      

   3. STEP3 Enter a city name and select a location from the list displayed.

      

      

      First, enter the name of the city where the place you want to look up is located. After entering the first few letters of the name, a list of several possible locations will appear.　Choose the best location from among them.

      Examples of candidate locations displayed

      • TOKYO JP (100090): UIC-code for a station
      • TOKYO JP (JPTYO): UN/Locode for a location
      • TOKYO JP (TYO): IATA CODE for an airport or location
      • TOKYO HANEDA INTERNATIONAL AIRPORT (HND): LOCAL AIRPORT CODE
      • TOKYO JP: No specific code

   4. STEP4 Enter a city name and select a location from the list displayed.

      

      Choose the destination in the same way as in STEP 3.

   5. STEP5. Set up a transit point, if needed

      

      ⇒　STEP5.Add transit point

      By pressing this button, you can add a transit point to the calculation. Up to three transit points can be added.

      

      A transit point information can be also deleted by pressing the X button in the upper right corner of the input box.

   6. STEP6. Press “Calculate” button

      

      Calculation results are displayed by transport section, as well as a summary of transport section totals

      For reference

      CO_2e=CO₂ equivalent

      TTW=Tank to Wheel

      WTW=Well to Wheel

      CO_2e Emissions(Tonne)=Transport Distance(Km) x Freight weight(tonne)x CO_2e intensity(gCO_2e/tonne-km) ÷１０⁶

      CO₂ Emissions(Tonne)=Transport Distance(Km) x Freight weight(tonne)x CO₂　 intensity(gCO₂/tonne-km) ÷１０⁶

   7. Reset Button

      

      To continue with another calculation, press the reset button and work from STEP 1
