Our Team

Leo Drynan

Leo provides technical leadership of the advisory services and supports service delivery within the environment and planning and natural hazards and resilience sectors.  As a highly experienced socio-economist, he focuses on the quantification of economic costs and benefits in data scarce environments. Working across Australia and the Asia-Pacific, Leo produces robust economic and financial models to demonstrate project viability and economic returns on investments. With a background in social and environmental impact assessment, he provides socio-economic impact assessment and distribution analyses to show, not only how a particular initiative directly performs, but also how associated indirect and induced impacts may flow through to the local communities and environment.

Leo has provided economic services to a number of local, regional and national governments within Australia and across the Pacific, as well as for organisations such as Transport for NSW, Asian Development Bank, World Bank and Secretariat of the Pacific Community.

Leo’s experience allows him to focus on impact assessment and management in support of infrastructure development. With comprehensive experience in national and international Environmental and Social Impact Assessment (ESIA), Leo has worked on some of the largest infrastructure projects (including oil and gas, mining, transport, hydropower) in Australia and internationally. He delivers environmental approvals, management plans and bankable ESIAs in accordance with project scale and requirements, local, state and national legislation, and applicable international standards.  Leo has also delivered a range of environmental assessments on behalf of Transport for New South Wales.

In addition to his impact assessment skills, Leo has a focus on economic appraisals and evaluations, considering social, environmental and developmental impacts of development. He uses his economic modelling skills to examine project feasibility, risk and performance, as well as identify the socio-economic costs and benefits that need to be considered in conjunction with environmental aspects in project decision making. He has authored numerous business cases, feasibility assessment and economic impact assessments.

Leo is a leader in the integration of transport, environmental and social factors within project decision making and option evaluation. Working to both State and Federal assessment guidelines, he has participated in the development of business cases for an extensive array of significant road projects across NSW. Working with standard road-user cost benefit analysis and more qualitative methodologies (e.g. multi-criteria assessment, adjusted CBAs, preliminary economic appraisals) Leo has aided client decision making through comparison of options and project feasibility.
