Who we are – Carbon Limits

Who we are

Carbon Limits was formally established in June 2005, but its origins date back to the early 1990’s. The company grew out of the energy and carbon services of ECON (now Poyry Norge), a leading Scandinavian consultancy.

With projects in more than 20 countries, Carbon Limits has garnered an extensive experience in the identification and development of emission reduction opportunities in traditional energy sectors, but also in capacity building and policy advice. Our geographical focus includes Africa, Russia, Central Asia and Middle East where the company has access to a network of local partners and government contacts.

Today we are a diverse team of engineers, economists, and policy experts with a focus on mitigation in the oil and gas sector, carbon and climate finance, emission reduction policies and MRV.
