How We Make an Impact
SME-Centric
SMEs make up 90% of businesses worldwide, employ 70% of the global workforce, and contribute over half of global GDP. However, many lack the time, resources, and expertise to engage in sustainability. We focus on bridging these gaps by providing:
Measurable impact tools
Simple, effective sustainability measurement and reporting.
Strategic consulting
Expert guidance tailored to SME needs.
Community & Collaboration
Peer networking and knowledge-sharing to accelerate collective action.
Our Theory of Change
Put simply, we recognise key barriers that SMEs face:
Lack of skills & knowledge
We provide jargon-free tools, training, and expertise.
Lack of time & resources
We simplify processes and offer hands-on support.
Lack of funds
We offer scalable, cost-effective solutions that focus on tangible benefits.
Through a mix of technology and tailored consulting, we help SMEs:
-
Measure and reduce carbon emissions.
-
Implement sustainability strategies that align with their business goals.
-
Enhance brand value, strengthen supplier relationships, and engage employees.
