Navigating the Net Zero Landscape

As companies are called on to confront the climate crisis and limit global warming to 1.5°C above pre-industrial levels, the goal of net zero has emerged as the pinnacle of corporate action. For such a vital and widely-cited concept, though, there is so little consensus on its definitive content. In this article we offer guidance on how to navigate the highly fraught net zero landscape.

The ambiguity of net zero

The generally assumed definition of net zero is the balancing of anthropogenic greenhouse gas (GHG) emissions with the anthropogenic removal of GHGs. On top of net zero, other jargon in this space includes:

  • Climate positivity — the removal of more GHGs than emission of GHGs. This also might be used to describe a net positive impact on the environment more generally.
  • Carbon neutrality — a similar state to net zero, including only carbon (CO2) and excluding all other GHGs.
  • Carbon negativity — a similar state to climate positivity, however also including only CO2.

Although the definition of net zero looks simple enough, once one explores how companies and organisations are approaching net zero, it becomes clear that there is not in fact a single agreed-upon standard. The confusion deepens with accusations of green washing levelled at supposedly net zero-aspiring companies, whose sustainability policies are criticised for obscuring continued damage to the environment. There is an evident need for wide-reaching and widely accepted clarification of the concept to standardise approaches to sustainability. But in the absence of this, how can companies seeking to improve their environmental standing navigate the ambiguous landscape of net zero? To answer this, we’ll look at the following questions:

  • What is generally agreed-upon as a framework for net zero?
  • Which concrete standard for net zero ought we employ?
  • Why is decarbonisation prioritised in this framework?
  • And how could we go beyond net zero?
What is generally agreed upon as a framework for net zero?

In October, the Science Based Targets Initiative (SBTi), a leader in defining sustainability goals, released their new definition of net zero which emphasised decarbonisation as the primary objective. The discourse on net zero, as a result, shifted to mimic this emphasis and converged on a broad framework:

  1. Significantly decarbonise the value chain.
  2. Set near and long term goals to achieve this.
  3. Neutralise (with offsets) all residual emissions that cannot be eliminated.
Which concrete standard for net zero ought we employ?

The Science Based Targets Initiative (SBTi) is the frontrunner in clarifying the concept of net zero with their Corporate Net Zero Standard, filling out the broad framework above. Crucially, SBTi requires a company to:

  • Decarbonise 90–95% of its value chain,
  • To halve their emissions by 2030,
  • To bring emissions close to zero by 2050.

The Corporate Net Zero Standard represents the best guide to net zero as the science-based approach ensures a company is securely set up to align with the Paris Agreement and the 1.5°C target. Moreover, the specificity and rigour of the SBTi requirements render it more straightforward to apply, despite its demanding nature.

Why is decarbonisation prioritised in this framework?

The root of the criticism of some net zero frameworks is their potential acceptance of carbon offsetting — the recapture and storage of carbon dioxide from the atmosphere via either natural or artificial means — as the primary vehicle for climate action. If we take our basic definition at face value, a company might be considered net zero if their offsets balance their emissions. This approach, however, is not acceptable on an individual level nor scalable globally for three key reasons:

  1. A pathway that focuses on offsetting reduces the urgency of the issue, providing an escape-route where companies can ‘burn now, pay later’.
  2. There are not enough natural carbon sinks to accommodate current emission levels and technological methods of carbon capture are far from developed enough to fill the gap.
  3. The use of offsets can create issues of social justice, equity and land use; many offsetting projects are undertaken internationally, where potential social harm is hard to assess and minimise.

As a result, achievement of net zero must be primarily the result of decarbonisation.

How could we go beyond net zero?

The demands of the SBTi standard present a daunting but achievable task. Some, however, propose steps that go beyond this.

  • SBTi itself recommends investment in other efforts to combat climate change beyond a company’s value chain, in addition to working towards net zero. These efforts may include forest conservation and restoration, and investing in carbon capture technologies.
  • The Taskforce for Scaling Voluntary Carbon Markets (TSVCM) recommends a ‘high ambition path to net-zero’, where companies offset all of their emissions in the period leading up to their net zero goal.
  • Companies could also look at their past carbon footprint, and consider offsetting historic emissions, as Google did in 2020.
Final thoughts

The concept of net zero remains ambiguous and contested. If it is employed as a goal in the face of criticism, it needs to be thoroughly defined and justified. The SBTi standard presents a reliable route to doing so. The standard, however, is evolving and likely to change.

We can view the confusion surrounding net zero as an opportunity to reflect on our real impact on the planet and aspire to an effective sustainability policy. Otherwise, we risk pursuing only a pretence of responsibility from an unscrutinised standard of net zero.
