Sustainability has become an important consideration for customers, investors, employees and regulators. Businesses are increasingly communicating their environmental achievements, promoting green products and presenting themselves as responsible corporate citizens.
However, there is a growing risk that sustainability communication may create a more positive impression than the available evidence supports. This practice is known as greenwashing.
Greenwashing occurs when an organisation misleads stakeholders, whether intentionally or through poorly substantiated communication, about its environmental performance, products, services or sustainability credentials.
How does greenwashing happen?
Greenwashing can take several forms.
An organisation might advertise a product as environmentally friendly without explaining the evidence behind the claim. Another might promote a tree-planting initiative while overlooking significant pollution from its main operations. A company might also describe its packaging as sustainable without explaining whether it can actually be reused, recycled or composted in the markets where it is sold.
Words such as green, eco-friendly, clean and sustainable can be misleading when they are used without clear definitions, boundaries or supporting evidence.
The problem is not environmental communication itself. The problem arises when the message gives stakeholders an inaccurate understanding of the organisation’s actual environmental performance.
Why should businesses be concerned?
Greenwashing can undermine consumer confidence, damage corporate reputation, expose organisations to regulatory or legal scrutiny and weaken relationships with investors and business partners.
It can also disadvantage businesses that genuinely invest in environmental improvements but communicate their achievements more cautiously.
For Zimbabwean businesses seeking to strengthen their ESG credentials, credibility is therefore an important asset.
How can organisations avoid greenwashing?
Businesses should ensure that environmental claims are specific, measurable and supported by reliable evidence.
Instead of saying, “We are a completely sustainable company,” an organisation could explain that it reduced electricity consumption by a stated percentage over a defined period, specifying the baseline and the method used to calculate the reduction.
Organisations should also disclose material environmental challenges rather than highlighting only positive developments. Where progress is incomplete, transparent reporting should explain what remains to be done.
Independent verification can provide additional assurance where appropriate.
From green marketing to genuine environmental progress
Sustainability claims should reflect actual performance, not simply the image an organisation wishes to project.
Businesses that communicate honestly, acknowledge their limitations and demonstrate measurable improvements are better positioned to build stakeholder trust.
The message is simple: do not just look green. Demonstrate the evidence behind your environmental claims.
ESG Network Zimbabwe encourages organisations to place transparency, accountability and measurable environmental outcomes at the centre of their sustainability communication.
