David Hogg has had a career as an environmental general practitioner spanning more than 40 years. In 1973, he joined the National Capital Development Commission in Canberra, establishing and heading its Environment Section. That Section was involved in the environmental planning and assessment of most major development projects in Canberra, and he was responsible for managing the environmental assessment of these projects under the new Commonwealth Environment Protection (Impact of Proposals) Act. He was also involved in the planning of major recreational projects in the ACT, particularly the development of the National Capital Open Space System.

In 1981, he left the NCDC to establish his own consulting firm in Canberra, David Hogg Pty Ltd. The work of that firm was focused particularly on the ACT, surrounding local government areas and Kosciuszko National Park. The firm continued to operate with a small staff until 2014. During that period, he was involved in approximately 700 projects, mainly in the ACT or in New South Wales ski resorts. In 2000, he collaborated with the resort operators to prepare the Perisher Ski Resort Ski Slope Plan which won a Royal Australian Planning Institute National Award for Planning Excellence in Environmental Planning or Conservation.

He was a foundation member of the Environment Institute of Australia, served on the ACT Division Committee from 1988 to 1996 and on the EIA(NZ) Council from 1996 to 2009, including eight years as Secretary and four years as Newsletter/ Communications Editor. His work on the Council included establishing a five-year Development Plan for the Institute, revising the Rules of Association to enable the incorporation of the New Zealand Chapter, reviewing and formalising the EIANZ bylaws, preparing an Operational Manual for the Council, and coordinating the upgrade of the EIANZ website. He has also been a member of the Policy and Practice Standing Committee since 2005, a member of the Management Committee of the Impact Assessment Special Interest Section throughout its existence, and Chair of the Professional Development Standing Committee from 2009 to 2014. In 2007 he was the first recipient of the Simon Molesworth Award for outstanding contribution to the development of EIANZ.

He became a Certified Environmental Practitioner shortly after the certification scheme was introduced and has been regularly involved in the review of certification applicants, both at the general level and for the Impact Assessment specialty.

In retirement, he is actively engaged in a range of research and writing projects, mainly of an environmental and/or historical nature. Some of these projects are an extension of his professional environmental work. He remains an active participant in EIANZ activities.
