Frequently asked questions about setting a scope 3 science-based target

According to the Paris Agreement, we need to reach net-zero emissions by mid-century to avoid catastrophic climate change. One way to translate from this requirement to corporate, transformational climate action is to set targets aligned to current climate science. Science-based targets provide you with a clearly defined pathway that specifies how much and how quickly you need to reduce greenhouse gas emissions.

In previous blog posts, I talked about general requirements in setting a science-based target; in this article, I’m answering commonly asked questions for developing a science-based target for your scope 3 emissions.

Do we have to set a science-based target for our scope 3 emissions?

According to the SBTi, you only need to set a science-based target for your scope 3 emissions if they are larger than 40% of your overall carbon footprint.

Does a scope 3 science-based target need to cover all scope 3 emissions?

Your scope 3 target boundary should collectively cover at least two-thirds of your total scope 3 emissions.

Does our scope 3 science-based target have to be absolute-based, or can it be intensity-based?

Your scope 3 target can be absolute, intensity or engagement-based.

Absolute-based means that you have to achieve emissions reduction from a certain baseline by a target year. Here is an example of an absolute-based reduction target for a scope 3 emission source: ‘Siemens AG commits to reduce absolute scope 3 GHG emissions 15% by 2030 from a 2019 base year.’

Intensity-based means that you have to achieve emissions reduction based on a metric such as ‘unit of production’, e.g., ‘tonnes’ if you are a manufacturer. Here is an example of an intensity-based reduction target for a scope 3 emission source: ‘Reduce GHG emissions per tonne of product by 30% by 2030 from a 2017 base year.’

Engagement-based means that you are engaging your value chain partners in settings SBTs, meaning that you are requesting your suppliers to set their own science-based targets. Supplier or customer engagement targets may be valuable if you

  • have yet to identify levers for more specific reduction opportunities amongst your value chain partners
  • you have mostly indirect expenditure and therefore don’t spend enough on individual suppliers to support collaborative reduction efforts.

It’s best not to use supplier engagement targets when the majority of emissions from purchased products and services come from tier 2 suppliers or suppliers even further removed from you, as you may not be able to influence emissions reduction.

Here is an example of a supplier engagement target: ‘Fisher & Paykel Healthcare Corporation Limited commits that 87% of suppliers by spend covering purchased goods and services and the use of sold products will have science-based targets by FY2024.’

Do scope 3 science-based targets need to be as ambitious as scope 1 and scope 2?

SBTi encourages you to set scope 3 targets using the same science-based methods required for scope 1 and scope 2; however, SBTi also accepts targets that it deems ‘ambitious’.

If your target is absolute-based, the minimum ambition is a 1.23% annual linear reduction (please note that this is different from the 2-degree pathway for scopes 1 and 2), but you are encouraged to pursue a 4.2% annual linear reduction.

If your target is intensity-based, you need to cap absolute emissions at a base year level and achieve a physical intensity reduction at a minimum rate of 2% in annual linear terms. For example, if you commit to reducing GHG emissions per tonne of product by 30% by 2030 from a 2017 base year, this is a 30 ÷ 13 = 2.31% intensity reduction in annual linear terms. 2.31% meets SBTi’s minimum physical intensity improvement requirement.

If your target is engagement-based, you must meet the target within five years to ensure timely emissions reductions.

The top 23 Australian universities for climate action commitments in 2021

In addition to tracking ambitious commitments of local governments and communities, 100% Renewables has been tracking carbon and renewable energy commitments made by Australia’s public tertiary education sector since 2017.

Our first University-related blog post published actions and commitments of several universities that demonstrated sustainable energy leadership. We highlighted examples of leading clean energy and low carbon research, divestments from fossil fuels, and examples of universities’ targets and actions to reduce their carbon footprint.

In 2020, we published a blog post series on a number of sustainability leadership topics that are relevant to the tertiary education sector:

  1. Commitments, actions and achievements of 14 leading universities across Australia
  2. Universities with Green Star certified buildings
  3. Universities that are signatories to the UN’s Sustainable Development Goals (SDGs)
  4. Universities with fossil fuel divestment commitments

This blog post revisits ambitious climate action commitments made by universities and provides an updated list. Since our 2020 blog post series, nine more universities have committed to ambitious goals, and several others have increased their climate ambition. A total of 23 out of 40 universities have now committed to ambitious climate action targets.

Below are some examples:

Out of the 23 universities in the ambitious commitments list, 11 have committed to 100% renewable energy on or before 2030, 11 have committed to carbon neutrality on or before 2030, and 7 have committed to net-zero GHG emissions targets on or before 2050.
