Is zero-emission products possible? The challenge behind carbon neutrality

Is zero-emission products possible?
The challenge behind carbon neutrality of products

Have you ever questioned what makes a product zero-emission? If so, we’re here to shed some light on what can often be confusing to those beginning their journey towards calculating their emissions. Throughout this article, we attempt to provide some clarity on the differences between emissions classifications and provide insight into why oftentimes calling your products ‘zero emissions’ can be misleading to stakeholders and consumers.

Understanding Your Emissions-– Scope 1, 2 and 3

Scopes 1 & 2

Greenhouse gas emissions can be understood within the context of three scopes [1], namely scopes one, two, and three. Scope one is what we define as direct emissions. Direct emissions constitute the most well-known and classic example of fuel combustion such as everything that comes out of an exhaust pipe or chimney and enters the atmosphere directly.

Scope two consists of indirect emissions and can be understood through the eyes of company consumption and other actions. An excellent example of this would be energy consumption. If a company utilizes a production line that demands electricity or if they have systems requiring heating or cooling this would fall into what we define as scope two.

Scope 3

Scope one and two have had their fair share of attention and reporting for the many past years. However, recently scope three has overtaken interest within environmental circles, and for good reason.

Scope three can be trickier to understand and assess. Actions that fall into scope three can often possess some of the highest amounts of atmospheric emissions and in some cases, more emissions can be expelled from actions in scope three, than from scope one and two combined. To break it down, scope three is defined as indirect emissions, just like that of scope two. Although, scope three is different in that it encompasses the indirect emissions related to activities throughout a company’s supply chain.

Essentially all emissions related to the upstream and downstream supply chain fall into scope 3 and include, but are not limited to, emissions from raw material extraction, transportation, and even infrastructure. These actions can be difficult to account for, however, they are necessary in order to fully understand emission outputs in their entirety. This is possible with life cycle assessments.

What About Zero-Emission Products?

The only zero-emissions product is a product that reports on all scopes of emissions–including scope 3. ‘Zero-emissions’ products are everywhere. Although, in order to fully claim a product has zero-emissions qualities a Life Cycle Assessment (LCA) must be conducted where the scope one, two, and three emissions are accounted for. Unfortunately, this isn’t common practice for many companies making sustainable product claims.

Irresponsible burden-shifting can mean that different activities with different emissions outputs end up being weighed equally and can therefore result in greenwashing. For this reason, assessing a product from cradle to grave, or from the point of raw material extraction for the product’s creation, all the way up until the complete disposal of the product is instrumental in making honest claims about the product’s entire output of emissions. Governing bodies are currently regulating legislation to lower industry emissions where documentation and reporting for scope 3 are on the horizon. This is pushing many companies into taking these as signs to become fast movers and engage in early reporting.

Is Zero-Emission Achievable?

Selling a product on the basis that it has zero emissions without first calculating the different impacts turns a blind eye to an essential part of holistically assessing the product. The first step toward creating a zero-emissions product is through creating a baseline of everything you know about the product. This is not easy work, but utilizing tools like Life Cycle Assessment (LCA) calculators is easily one of the best places to start.

Tools like life cycle assessments (LCAs) allow you to quantify products with both generic data and company-known data allowing for more in-depth and transparent reporting. Fortunately, extensive digital libraries are also available to make this data even more accessible to everyone.

From here it becomes easier to calculate the scope of emissions, see where hotspots are, and where attention is needed to get closer to a truly sustainable product. It’s safe to say, what would have been deemed impossible just 30 years ago has today become achievable through the use of these impact assessment tools [2].

Carbon Footprint Accounting? Here’s what you need to know

Carbon footprint accounting? Here's what you need to know

Life cycle thinking in carbon footprint accounting

Activity-based approach and spend-based approach are two common Greenhouse Gas (GHG) accounting (commonly known as carbon footprint accounting) methods. While both are compatible with life cycle thinking, they differ greatly in the origins of inventory data and emission factors. Distinct origins and characteristics of the data used in these two approaches lead to significant differences in the data collection process, resulting in GHG inventories with varying levels of details, specificity, representativeness, and accuracy, and accordingly the applicability of the accounting results to decision making for corporates, consumers, and regulators.

Inventory: technical-physical data vs. financial data

The activity-based approach necessitates engineering process data of the processes managed by the reporting company as well as its suppliers and service providers, e.g. Bill of Materials. The collected data are in physical units such as kilograms and kWh. They are principally process-specific primary data supplemented by secondary market average data. The data collection process usually takes time and effort, however, it yields detailed, representative, and consistent results.

Differently, the spend-based approach requires exclusively financial data or purchases, and values are expressed in monetary units. Data from suppliers or service providers is not needed, thus reducing the time and resources for the inventory data curation process. However, financial data are subject to price fluctuations caused by varying exchange rates, changing market conditions, as well as other temporal and geographical factors. For instance, the same product bought in different purchasing conditions may have distinct GHG footprints, while the factual GHG emissions should remain the same. These complicate the spend-based approach and add great uncertainties not only to the financial inventories but also the GHG accounting results.

In this video we discuss and explain the differences between Spend based and Activity based approaches

Application: credible and consistent accounting vs. screening

The accounting results developed based on the activity-based approach provide a good representation of the reporting company’s specific value chain activities. The accounting allows the reporting companies to conduct baseline setting and identify key contributors and accordingly develop emission reduction plans. Given the consistency and credibility of the primary data and high-resolution emission factors, the obtained accounting results can be used to track progress of the reporting companies towards reduction targets. 

The spend-based method can be a helpful tool for corporates to approximate organizational or product-level footprints during the initial screening phase of the climate combat journey. However, given the lack of specificity and consistency in the inventory data and low-resolution emission factors, GHG accounting based on the spend-based method is not recommended to be used for reporting or monitoring.

More to Sustainability?

Is there more to sustainability?

Sustainability is one of the new mega trends in the maritime industry. The industry has for many years avoided the focus of the consumer – that has now changed. A recent report from Unilever shows that a third of the consumers would prefer sustainable brands.

This leads to the question – What is sustainability? We often talk about sustainability in an environmental context. In 2005 the World Summit on Social Development identified three main pillers of sustainability. Sustainability focuses on meeting the needs of the present without compromising the ability of future generations to meet their needs. The investment and banking corporation ING predicts in it’s recent sector analysis that future investors in maritime industry are more likely to invest in shipping companies with sustainable initiatives.

Three pillars of sustainability

Economic Sustainability

This refers to practices that support long-term economic growth without negatively impacting social, environmental, and cultural aspects of the community.

Social Sustainability

The ability of a community to develop processes and structures which not only meet the needs of its current members but also support the ability of future generations to maintain a healthy community.

Environmental Sustainability

This refers to harvesting renewable resources that can be continued indefinitely, minimizing pollution creation, and avoiding non-renewable resource depletion.

Where are we heading?

One of the core factors on why economic sustainability projects fails is the fundamental notion that you are often rewarded in doing something bad for the environment. An example: a shipowner is rewarded by using high-sulfur compared to the more expensive and “greener” low-sulfur alternative. The latest initiative from IMO with the 0,5% sulfur cap by 2020 – is a clear game changer for the maritime industry. Here the international regulatory institution leveled out the playing field- rewarding early adaptors and innovators.

The process of regulating vessel emissions is reaching a mature stage – where are regulators looking next ? One can only guess! One of the areas missing attention is vessel maintenance – one could ague that a greener profile of a vessel should be defined is a larger context including the maintenance, spare-parts, logistics and crewing.
