This ethos underlines Third Line Group, which integrates strategy, audits, and ISO 20121 implementation to identify sustainable investments in growth market regions.
Corporate Sustainability Strategy
Benefits beyond compliance.
Move your business from compliant sustainability reporting to sustainability leadership by identifying risks and opportunities from non-financial issues such as climate change, labour relations and social reputation.
South African sustainability strategist Alex Hetherington founded Hetherington Sustainability in 2004. The core services of the company centre on proving the bottom-line business case of sustainability by identifying efficiencies in companies that ultimately result in financial profitability to the business, benefit to its social stakeholders and minimised impact on the environment.
We've helped these clients move towards sustainability leadership: WWF-South Africa, Nedbank, Sanlam, Santam, Investec and Bidcorp.
