Carbon Footprint Measurements
A carbon footprint is defined as the total greenhouse gases (GHG) emitted by an entity, and is expressed in carbon dioxide equivalent (CO2 eq). An entity can refer to any source including from an individual, organization, locality, product, or project. Emissions are generated from all kind of activities from energy use and land clearing, to waste management and services purchased. GHG emissions are usually divided into three categories:
- Scope 1 – Direct emissions: come directly from an activity or action such as burning fuels in a car, boiler, or a stove.
- Scope 2 – Indirect fuel emissions: are emitted in the processes performed by energy suppliers to produce the energy that one consumes. An example of this is the burning of coal or gas to generate electricity.
- Scope 3 – Other indirect emissions: are emissions that occur in the up or downstream processes of a supply chain. This could be the extraction of raw materials, production of food, transport unrelated to the direct emitter, or waste treatment.
The division between the emissions categories is reliant on the perspective of the point of measurement. This is therefore correlated with how much power one has over these emissions and their reduction. For example, a paperclip factory does not have too much control over how the electricity it uses is produced (scope 2 emissions), and even less influence for how the steel is extracted and made (Scope 3). However, it does have relatively more power in determining/investing in the efficiency of the machinery it uses and the direct operations occurring at the factory (Scope 1).
The definition between these various integrated activities, that in this case come together to make a paperclip, is sometimes unclear. Therefore, it is very important to be precise in categories and what to include in them. That is why standards have been developed to help companies, authorities and even individuals navigate through accurate GHG accounting.
Greenhouse Gas Protocol is a globally recognized organization that is developing frameworks for measurement and management of GHG in the public and private sector. Standards developed by Greenhouse Gas Protocol serve as a common ground for many reporting systems and certification programs.
They define the main concepts connected with a carbon footprint, divided the emission into Scope 1, Scope 2, and Scope 3, and help the user navigate through the GHG inventory process. This protocol also provides support in setting carbon reduction targets, managing emissions, and reporting the resulting carbon footprint.
Why Carbon Footprint is Important
A carbon footprint calculation is the first step to developing more energy efficient business operations or identifying sustainability targets. By measuring the current types and sources of emissions, and mapping them out in a carbon footprint, it is easy for a company to identify “hot spots” and compare themselves with existing industry standards or benchmark against national targets.
It is important to begin by measuring a carbon footprint before investing in efficiency or sustainability improvements, and Ecomatters is here to help. We have been quantifying environmental impacts for over a decade and have extensive experience with carbon footprint (CF) calculations. We are up to date on the different standards such as the Carbon Disclosure Project and the Greenhouse Gas Protocol. In addition, we can help you develop customized carbon footprint calculation tools for your business or organization.
We are committed to making quantified results more than just numbers. We help our clients turn basic carbon measurements into action and in order to achieve effective results and communication.
