Best practice tip to communicating on climate

With ongoing debates and the ISO standard on carbon neutrality still in discussion, are you looking for solid guidelines for exemplary communication about your commitments? Faced with the pitfalls of corporate greenwashing, communicating about your climate efforts can feel like a minefield!

The lack of a standardised framework and methodology on corporate carbon neutrality or net zero is certainly an obstacle to effective communication, yet stakeholders are increasingly demanding and sometimes require transparent and thoughtful communication.

In order to limit climate change in accordance with the latest scientific knowledge, we all must get involved. Your organisation has a role to play in facilitating action by society as a whole, as quickly as possible. In the face of the climate emergency, we know that we must act and report on our actions in the most transparent and responsible way possible.

What are the challenges of communicating your climate commitments?

In the race to meet global climate targets, organisations around the world are required to communicate their climate impact and commitments to reduce it.

Momentum is gathering. For example, the Race to Zero campaign is mobilising a coalition of leading net-zero initiatives representing 733 cities, 31 regions, 3,067 businesses, 173 of the world’s largest investors and 622 higher education institutions. These economic actors join 120 countries in the largest ever alliance committing to reach net-zero emissions by 2050. Collectively these actors now cover nearly 25% global CO2 emissions and over 50% of global GDP.

Communicating effectively not only demonstrates compliance with national and international regulations, but also shows foresight and increased ambition. Well-managed and convincing communication can strongly influence an organisation’s image, but above all it is a powerful driver of change. Raising awareness and sharing innovative climate solutions can lead to real and lasting change for your organisation.

Similarly, engaging the public and other stakeholders through responsible communication contributes to the success of your climate efforts. Effective communication fosters dialogue and unites people around the common goal of acting to preserve the climate and the biodiversity of our ecosystems.

What are the main challenges in getting your message across?

The main challenge for many organisations is the lack of a rigorous and ambitious regulatory framework. In the absence of a commonly agreed-upon, standardised definition of carbon neutrality or net zero at a corporate or organisational level, climate ambitions and actions are very heterogeneous across organisations, sectors and geographical areas.

As a result, the language used to talk about climate commitments and actions is often highly technical, sometimes imprecise, and can even be misleading. The challenge is therefore to be technically correct, accurate, and consistent with the latest climate science, while being accessible to your stakeholders.

Valuing your organisation’s voluntary climate action  

In this essential step on your journey to net zero, you have a twofold objective that can be summarised as follows:

  • Demonstrate your climate efforts and progress so as to differentiate your communications from those of less ambitious competitors.
  • Follow best practice when communicating your climate-related commitment, in order to avoid reputational risks.

Our guidelines for communicating about your climate impact

The golden rule is to be transparent. In practical terms, this means reporting on your organisation’s full carbon footprint, calculated in tCO2, clearly specifying:

  • The organisational, geographical and emissions scope of your carbon footprint. The objective here is to report on all significant direct and indirect emissions (3 Scopes). Consequently, it is crucial to justify any exclusions and to precisely identify your significant emissions (which are often in Scope 3).
  • The standardised and recognised calculation methodology used (ISO 14 064, GHG Protocol, Bilan Carbone®, etc.).
  • The breakdown by scope of emissions and by category of emissions.

Ensure that you have met all GHG reporting obligations before communicating your voluntary approach.

Our guidelines for reporting your climate commitments

First and foremost, clarify the scope as outlined above. Keep in mind that this communication should be clear and accessible to the general public. Thus, we recommend you offer an easy-to-understand comparison (e.g. an average carbon footprint equivalent to that of a well-known city).

Your communication should include detailed targets for reducing your carbon footprint across the value chain. Most importantly, your communications should demonstrate a long-term vision aligned with the net-zero goal and supported by an ambitious yet achievable action plan to reduce direct and indirect emissions, based on climate science (e.g. a science-based target). This means that the reduction must be consistent with the Paris Agreement’s 1.5°C trajectory or with the net zero global goal as described by the IPCC.

Reduction is your first objective, complemented by the offsetting of residual emissions. It is essential to specify the emissions that you remove from the atmosphere, for example via the enhancement of carbon sinks.

Communicating about your achievements

Be transparent about your progress against previously set targets. The key is to communicate in an integrated way, supported by quantified results and clear references to the norms or standards you have used. Indeed, the offsetting targets must be directly linked to the reduction targets with reference to residual emissions. Companies should feel comfortable talking about activities that need improvement, in an open manner, e.g., listing also challenges ahead (it reinforces their willingness to meet their targets).

Some things to bear in mind before making statements

Be aware that the definition of carbon neutrality and net zero are being debated by reference bodies such as ISO, SBTi and UNFCCC. Therefore, changes may occur in the near future.

We recommend relying on standards, rather than using non-standardised terms that imply no impact, such as ‘carbon-free’, ‘zero-carbon’, ‘carbon-negative’ or ‘carbon/climate positive’, as well as the term ‘climate neutral’.

We recommend claims that illustrate that your efforts put you on a trajectory consistent with the most robust long-term goal of net-zero emissions*, such as

  • Aligned with the net-zero ambition;
  • Compatible with the global net-zero target;
  • On a path to net zero
  • Contributing to the net-zero transition.

Thus, communicate your commitment to net-zero emissions, but do not claim having achieved it. It is strongly recommended that you monitor legislation evolution to avoid legal risks.

Promote the initiatives that will help you transition to net zero

Showcase the transformation of your business model that is needed to make the transition to net zero feasible. This is an opportunity to communicate on your eco-design and technological innovation that help you avoid emissions, as well as on your progress in climate risk and opportunities assessments that help you adapt and transform. It is particularly important to showcase how your innovative solutions create real impact on the ground, to people.

Finally, for maximum credibility, bear in mind that validation by an independent third party will help your organisation move from a declarative model to a performative model based on results.

* Although there is no standardised definition of the concept at company level to date, EcoAct uses the most robust and scientifically based approaches (SBTi) to define it. Therefore, for an organisation, being net zero means:

  1. Having reduced its direct and indirect GHG emissions in line with a 1.5°C trajectory, having come as close to zero emissions as possible, and
  2. Having removed from the atmosphere an amount of CO2 equivalent to all its residual emissions over a specified period.
