About CLEEN
Climate solutions, rooted in Africa
CLEEN — the Climate, Ecosystems, Energy & Sustainability Network — is a Pan-African sustainability consultancy that bridges evidence-based research and on-the-ground action. We work with national governments, municipal authorities, civil society, and the private sector to design, finance, and deliver climate and sustainability programmes that are technically rigorous and deeply contextualised to African landscapes, economies, and communities.
What drives us
Our Mission
To accelerate equitable, evidence-led sustainability transitions across Africa — helping governments, communities, and organisations reduce emissions, restore ecosystems, and build long-term climate resilience through locally owned strategies and measurable outcomes.
Our Vision
An Africa where sustainable development is not an aspiration but a lived reality — where climate-smart economies thrive, biodiversity is protected, clean energy is universal, and future generations inherit a continent that is resilient, just, and prosperous.
How we work
A structured engagement model that delivers clarity, ownership, and results at every stage of the consulting relationship.
Listen & Assess
We begin every engagement by immersing ourselves in context — consulting local stakeholders, reviewing policy environments, and conducting rigorous baseline assessments to understand the real constraints and opportunities.
Design with Partners
Solutions are co-designed with governments, communities, and implementing partners. We combine global best practice with place-based insight to produce strategies that are technically sound, politically feasible, and culturally grounded.
Deliver & Measure
Implementation is supported by robust monitoring frameworks, capacity-building programmes, and adaptive management. We track outcomes against agreed indicators and report transparently to all stakeholders.
