Does methyl bromide fumigation of export consignments count in Scope 1?

No. Methyl bromide is an ozone depleting substance under the Montreal Protocol, and the GHG Protocol's scopes cover only the seven Kyoto gases. So it stays out of your Scope 1 total. If a buyer wants it disclosed, give the kilograms used in the year as a separate memo line beside your inventory.

Why it sits outside the scopes

Scopes 1, 2 and 3 count seven gases: CO2, methane, nitrous oxide, HFCs, PFCs, SF6 and NF3. Methyl bromide, like the CFCs and HCFCs, is regulated by the Montreal Protocol for the damage it does to the ozone layer. The Corporate Standard allows such gases to be reported for information, kept apart from the scope totals.

Why fumigation still uses it

Methyl bromide is phased out for most uses under the Montreal Protocol, but quarantine and pre-shipment uses are exempt. Importing countries and plant quarantine rules can require it for certain goods and wood packaging. In India its import and use are controlled under the Ozone Depleting Substances (Regulation and Control) Rules, 2000.

Who would report it, if anyone

What to write if a buyer asks

  1. State that methyl bromide is excluded from Scope 1 because it is not a GHG Protocol gas.
  2. Give kilograms used in the year from the fumigation register, as a memo item.
  3. If you add a CO2e figure, name the GWP source, such as the IPCC AR6 Working Group I table, and keep it out of the totals.
  4. Mention alternatives you use, such as heat treatment for wood packaging, where they apply.

What Senseible does here

Senseible keeps fumigation agency invoices with their SHA-256 fingerprints in the supplier evidence trail and calculates the fuel and electricity used at your packhouse or warehouse from their bills.
