Scope 4 greenhouse gas emissions are not new. They date to 2013 when the Greenhouse Gas Protocol identified “avoided emissions” as emission reductions that occur outside of a product’s lifecycle or value chain, but as a result of the use of that product.

It was actually a decade ago that the GHG Protocol released “a survey to scope out the need for a new standard to help companies quantify and report the ‘avoided emissions’ of goods and services that contribute to a low-carbon economy – such as low temperature detergents, fuel-saving tires, or teleconferencing equipment and services.” And from that survey, Scope 4 GHG emissions were born.

Some context is helpful, especially for those just getting their arms around measuring and reducing GHG emissions:

Scope 1 GHG emissions are “direct emissions” that occur from sources that are controlled or owned by an organization (e.g., emissions associated with fuel combustion in boilers, furnaces, and vehicles) and are modest in abundance.   

Scope 2 GHG emissions are “indirect emissions” associated with purchased electricity, steam, heat, or cooling and are generally greater in contribution than Scope 1. Although Scope 2 emissions physically occur at the facility where they are generated, they are accounted for in an organization’s GHG inventory because they are a result of the organization’s energy use.

Scope 3 GHG emissions are the result of activities from assets not owned or controlled by the reporting organization, but that the organization indirectly impacts in its value chain both upstream and downstream (.. we are doing Scope 3 studies in several business sectors and the calculations are batshit crazy) almost always representing the majority of an organization’s total GHG emissions.

Scope 4 GHG emissions are “avoided emissions” not a required scope to currently report in many contexts (as are Scope 1, 2 and 3). Scope 4 are squishier and do not have broadly accepted standards. They quantify the impact of an organization’s products on reducing emissions outside of their value chain, including avoiding emissions saved by efficiency improvements or reductions in carbon emitting activities. And while they are a decade old, their use is emergent and exploding on the scene.

A good example of Scope 4 emissions may be the GHG emissions avoided by the use of video conferencing. Arguably Zoom Video Communications avoids significant emissions. The communications technology company’s Zoom platform reduces the number of employees commuting to the office, staffers traveling to meet clients, and reductions in other carbon emitting activities, thus causing emissions to be avoided which are quantified as the Scope 4 emissions for the communications technology company.

Another example of Scope 4 emissions may be GHG emissions avoided by the efficiency improvements of low temperature laundry detergent. Unilever ran television ads in the UK for its washing liquid stating that “Persil products remove stains at 30 degrees Celsius and in 60 minutes.”  And the ad concluded, the brand “continually improves their products to be kinder to the planet.” However, the television ad has been banned by the UK Advertising Standards Authority for greenwashing and making misleading environmental claims over the protestations of Unilever which argued it is well documented that reducing the temperature of a wash reduces carbon emissions and that this ad helps promote this.

Companies need good hard facts when making ESG claims including GHG emission claims and specifically cutting edge Scope 4 emission claims. One of our key roles is to caution clients not to make unqualified general environmental claims because ‘‘it is highly unlikely that [businesses] can substantiate all reasonable interpretations of these claims,’’ the Federal Trade Commission standard for challenging environmental claims.

As companies strive to hang meat on the bones of their Net Zero pledges, Scope 4 emissions will be valuable tools for success. Reporting on Scope 4 avoided emissions may allow for a business’ reputation to be enhanced by not only describing the climate positive value of the product or service but promoting the “decarbonizing power” of the product.   

We are assisting companies in using avoided emissions to help them reach their climate goals and meet increasing demands from stakeholders including customers, investors, and regulators.
