montreal protocol

Discover with thinkstep GaBi LCA Data the success of the Montreal Protocol on substances that deplete the ozone layer.

What is the Montreal Protocol?
The Montreal Protocol regulates the fade-out of certain ozone-depleting halogenated hydrocarbons. The treaty provides a timetable for phasing out the production of different groups of substances.

The protocol is a multilateral environmental agreement, binding under international law and was agreed to in 1987. It has been successfully implemented since 1989 and has undergone eight revisions (from 1990 to 2016).

Affected Substances
The substances of the first group (CFC-11, CFC-12, CFC-113, CFC-114, CFC-115) needed to be phased out by 1996. The phasing out (to zero by 2010) of the less damaging substances began in 1996 (like Halon-1211, -2402, -1301, Halon 1301, 2402; CFCs 13, 111, 112). Exceptions are granted only for a limited number of highly specific applications, such as for the military or nuclear energy.

HCFCs are used in a wide variety of applications, including refrigeration, air conditioning, foam blowing, solvents, aerosols and fire suppression. Although there are currently 34 HCFCs that are subject to the phaseout, only a few are commonly used. Historically, the most widely used include HCFC-22 (usually as a refrigerant), HCFC-141b (as a solvent and foam-blowing agent), and HCFC-142b (as a foam-blowing agent and component in refrigerant blends).

How GaBi LCA Databases Respond
In the GaBi LCA Databases we try to follow the Montreal Protocol fadeout of ODP substances as closely as possible, reflecting the success of the fadeout and the recovery of the ozone layer that actually happens. This means that in annually updated GaBi LCA Data, you can see datasets change with the ODP reductions over time, depending how relevant a phase-out for a certain product is.

thinkstep always aims to keep its own LCI data most up-to-date concerning (not only) the Montreal Protocol effects.

thinkstep*. Your results can profit from up-to-date data!

* However please be aware that non-thinkstep LCA data of important other background data suppliers, may not be updated on yearly basis or do still use older versions of ts data (with higher ODP values) and provide it into GaBi for general use incl. crediting of by- and co-products.
Meanwhile ODP may only be relevant in LCA, if your scope includes research, nuclear energy, military and specific pharma. If you do an LCA in this specific sectors, you may describe it in the goal and scope of your project anyway and collect primary data. If your main focus is outside this sectors, you may use GaBi LCA Data.
