Like the Nazca vandalism, Teske, a Greenpeace employee and activist, had promoted the Greenpeace scenario in the IPCC special report on renewables. Teske had been Lead Author of the chapter responsible for critical assessment of the feasibility of the Greenpeace renewables scenario – an assessment that was not carried out in the chapter or report, despite expectations of policy-makers and the public.
The Greenpeace scenario was then equally uncritically promoted in the IPCC press release, from which the following statement was widely distributed:
Close to 80 percent of the world‘s energy supply could be met by renewables by mid-century if backed by the right enabling public policies a new report shows.
WG3 Co-Chair Ottmar Edenhofer defended Teske at the time as having been nominated by the German Government:
Sven Teske was nominated as an author by the German government and selected by the WGIII as Lead author in the IPCC’s continuous effort to draw on the full range of expertise, and this includes NGOs and business as well as academia.
