Terra Development Organisation Ltd is a UK-based Social Enterprise that since 2017 creates opportunities to achieve sustainable development at a global scale. Since 2020 TerraDev SL was created in Spain to cover EU.

We do our part by offering a wide range of sustainability and engineering consulting through research activities, as well as training, education, capacity building, community outreach and awareness programmes.

Sustainability means profitability. We add value to businesses which seek competitive growth through efficiency, ethics, good governance, and environmental protection. We go beyond local and international compliance, we can help you become more efficient, communicate with your stakeholders, train your staff, and  become more socially and environmentally responsible.
We offer engineering, environmental and sustainability services tailored to your needs. 

We offer services for local government and municipalities in engineering consultancy, energy efficiency, water management, waste water management, waste management, sustainability management systems and capacity building. We build relationships and partnerships with the private sector and other municipalities abroad. We can assist preparing conferences, implementing new policies, as well as, training and community outreach.
