Scope 3 emissions is a missing piece of the Net Zero puzzle that can’t be and shouldn’t be ignored!
By Rinika Grover
After the COP26 Glasgow Conference, 2020s is recognised as the ‘decade of delivery’ given fundamental transformations are needed to limit global warming to 1.5°C. Globally, Governments, Institutions, Industry and various other key players are reviewing their commitments to curtail greenhouse gas (GHG) emissions. Their prime focus is the maximum reduction of emissions by increasing both the mix in renewable energy and efficiency of energy consumption. These changes, once realised, will be enhanced by the creation of ‘carbon sinks’ to balance out the remaining emissions in the atmosphere. This is often referred to as Net Zero, whereby the global net emissions into the atmosphere are equalled by the removal of the equivalent greenhouse gases being removed from the atmosphere.
Is this enough? Will the world reach its Net Zero emissions by 2050? Else we are headed to a dystopian world, where we would experience a devastation at a global level with many low-lying countries being totally wiped out due to the increase in sea levels.
In response to the imminent growing threat and unsettling situation, many countries have pledged to accelerate their Renewable Energy mix. By example India enshrined a target of 50% of its energy requirements being met from renewable energy by 2030. Similarly, all of UK’s electrical energy will be generated from clean energy sources by 2035. To reach Net Zero by 2050, it is envisaged that 90% of the electricity produced will have to be from renewable sources. In tandem other clean energy fuels, such as biomass or Hydrogen, which are considered as important energy sources for a decarbonised world are being reviewed.

Is this the harbinger of change that we were anticipating? The transition to Net Zero is certainly a laudable aspiration, however not a straightforward one. Achieving Net Zero transition calls for a reduction of ‘Total’ emissions, in all 3 categories, namely Scope 1, 2 and 3 emissions. There are more specific and visible efforts focussed to address the Scope 1 and 2 emissions, which are emanating from direct and indirect sources of energy and occur in controlled environments. Now the spotlight needs to shift to Scope 3 emissions, also known as the ‘value chain’ emissions, failure to do so will result in the incomplete delivery of the Climate Change strategy.
Scope 3 emissions are the biggest part of ‘Total’ emissions and the most difficult ones to abate, given their nature, and consensus to measure. Consequently, most Industries grapple with in disclosing Scope 3 emissions as these emissions are not directly controlled by them.
Let’s delve into this further to have a deeper understanding! Transport Sector, is one of the top 4 carbon intensive industry, emitting extensive amount of carbon in particular its contribution in Scope 3 emissions. The Sector contributes about nearly 25% of all energy related GHG emissions. This is one of the compelling factors for the Automobile Industry, a critical pillar, to accomplish their Net Zero emission aspirations. There is a constant focus on implementing a range of initiatives that support the carbon abatement targets, and by just reducing emissions in manufacturing will not be sufficient. What consideration is being given to other emissions produced in the value chain such as during use or raw materials procurement phases?

The explosive growth of the Electric Vehicle (EV) in the Automobile sector, leading the move away from fossil-fuelled combustion engine, is certainly a steppingstone towards the Net Zero finish line. The changing legislations as exampled in the US by the Biden administration setting a goal of 50 % EV sales by 2030, will surely gear up a revolution to reduce the Sector’s scope 3 emissions in the ‘Use’ phase and create a ripple effect. Established car makers such as Volkswagen and Tesla have already enshrined targets and set the momentum for EV models. This has further led to the announcement of an exit model from the internal combustion engine by other manufacturers.
From the outset, it must be understood that the largest contributor of emissions is not just from the use phase, tail pipe emissions, but also from the production of raw materials, the latter is also categorised as Scope 3 emissions in the carbon footprint journey for the Automotive Sector. This is propelling automakers to work in collaborations with the supply chains to define their carbon abatement plans and extending the same to their own supply chains.
We can’t avoid or sideline Scope 3 emissions when evolving an ideal Climate Strategy given its significance and size in the total pie of emissions generated.

Smaller steps, as illustrated below, that reduce Scope 3 emissions in an overall plan could generate a snowball effect in the overall Net Zero plan. It is a 4-C-model- Capture, Clean Energy adaptation, Circularity of resources, and Communication
- Capture: Start with measuring, assessing Scope 3 emissions. There are 15 essential categories in Scope 3 to evaluate GHG emissions. It’s important to identify and capture emissions from value chain processes that are extremely deep rooted. This helps to formulate a baseline to compare with in future.
- Clean energy adaptation – From the list of processes, identify the ‘low hanging fruit’ initiatives that can be easily implemented, and where electricity and heat sourced from renewables such as solar, wind, geo, biomass or hydrogen can be obtained. For instance, shift gradually to items where there is already support being developed in the ecosystem; EVs are prime examples which are gradually gaining popularity as charging infrastructures’ mushroom.
- Circularity of Resources: Identify the major processes in supply chain that contribute to extensive emissions as a little change in those will have a gargantuan impact on any total emissions reduction journey. For instance, the production of raw material in the Automotive Sector will entail a major contributor in total emissions after the use phase. Introducing a small change towards sustainable natural resources, will create large outcomes in the domain. Here ingenuity adopted in processes for material recovery, reuse or recycling efforts will be lauded.
- Communication and awareness – This are a critical step, and there is a need to create awareness within the Sectors to influence their supply chains to become green. Further, it entails a larger message to enlighten consumer and society to be minimalistic and promote sustainable lifestyles.
