Tutorial: a worked example

A worked example: $1 million of cement, sector 327310, at 2012 producer prices.

Step 1. The sector

Type cement in the sector box and choose 327310 — Cement, or pick the group Manufacturing and then the sector from the list. Either way, the box and the two lists show the same sector.

Step 2. The amount

Leave the mode on Dollar amount and enter 1000000. Leave the year at 2012 and the basis at Producer. If your price were a 2018 purchaser price, you would set those instead and the tool would convert it; the conversion is shown with the results.

Step 3. The category

Choose Greenhouse gases.

Step 4. Run

Press Run the model.

Reading the results

• Greenhouse gases are 8.76e+06 kg CO₂ equivalent per $1 million; 11% of that occurs upstream of the cement plant. The contributing-sectors table lists 327310 Cement at 90.4%; 221100 Electricity at 5.7%; 212100 Coal at 1.3%; 211000 Unrefined oil and gas at 0.5%; 484000 Truck transport at 0.3%.
• Carbon dioxide alone is 8.58e+06 kg; the greenhouse-gas total also counts methane and other gases. Say which one you report.
• Open drivers under an indicator to see the flows that make it up. Switch the category to Air emission flows for the individual pollutants in the table above.
• Results scale with the dollars: $2 million gives twice every number.
