What is Net Zero?

Net zero is a state in which the Green House Gases (GHG) emitted into the atmosphere are balanced by removal from the atmosphere

Strategy: get rid of GHG through energy efficiency, electrification, renewables, etc

Carbon Neutrality:

It is a state of net zero carbon emissions achieved by offsetting the same amount of carbon dioxide[CO2] that you emit into the atmosphere

Strategy: (Power Purchase Agreements) PPE, renewables, etc.

Energy Efficiency:

Energy efficiency is the use of less energy to produce the same result or perform the same task.

Strategy: Energy Star appliances, LED Lighting, EaaS etc

What are Scope 1, 2, and 3?

If you're hearing about Scope 1, 2, and 3 emissions for the first time, it's unlikely to be the last. Scope 1, 2, and 3 are three categories of emissions;

  • Scope 1 - the Green House Gas (GHG) emissions that an organization releases directly from a business operation (like emissions from a generator, Boilers, fleet vehicle etc.)
  • Scope 2 – GHG emissions are indirectly released from the energy purchased by an organization (like emissions from a fossil fuel burning power plant to generate grid electricity, purchased steam, chilled water, compressed air etc.)
  • Scope 3 – all indirect GHG emissions in the organization's value chain, including upstream and downstream emissions. (There are 15 categories of Scope 3 emissions according to GHG protocol:

Upstream and downstream leased assets; Upstream and downstream transportation and distribution; Processing of Sold Products; Use of Sold Products; Franchises; Investments; End-of-Life Treatment of Sold Products; Purchased goods and services; Capital goods; Fuel- and energy-related activities; Waste generated in operations; Business travel; Employee commuting.

Three Important Takeaways

1
Net Zero and Carbon Neutrality are Different.

Net zero considers all GHG vs Carbon neutrality only focuses on Carbon Dioxide. The major difference between Net Zero and Carbon Neutrality is that in Carbon neutrality offset strategies can be deployed. In contrast, Net zero does not allow any offsetting.

2
Scope 3 Emissions are Important:

Scope 3 emissions account for a significant amount of their carbon footprint for most businesses(typically more than 70%). For example, an organization that manufactures products will often have significant Scope 3 carbon emissions from processing the raw materials versus a service company.

According to Science-Based Target Initiative (SBTi) criteria, "If a company has significant scope 3 emissions (over 40% of total scope 1,2 and 3 emissions), it should set a scope 3 target."

Rules for Emissions Accounting and Allocation:

Organizations must identify the operational boundaries between them and their suppliers/partners /customers across the value chain to correctly account for and allocate carbon emissions. There are two critical rules for accomplishing this:

A Scope 1, 2, and 3 are mutually exclusive for an organization - If the emissions are already accounted for in Scope 1 or 2 of an organization, they can't be accounted for in its Scope 3, to avoid double counting. For example, the indirect emissions from electricity consumption are categorized as and accounted for as the consumer's Scope 2 emissions. Therefore, they cannot be accounted as purchased products or services in its Scope 3 emissions.

B The same emissions can be double counted between organizations - The emissions of one organization can be allocated to another organization if they have related business activities. For example, a manufacturer's emissions from producing a product can be allocated to the customer who buys that product as upstream Scope 3 emissions.
