University of Otago botanist Prof Sir Alan Mark, who is also chairman of Wise Response, said a recent report ''Going Global: Pathway for New Zealand's transition to a low carbon economy'' would be presented and discussed by the three senior MPs, from 6pm.
The report, by English consultants, was commissioned by the cross-party GLOBE-NZ Group of 35 MPs from all seven current political parties, he said.
The speakers are Dr Kennedy Graham, Green Party spokesman on climate change and convener of the GLOBE-NZ Group, David Parker, Labour's spokesman on the environment, and Stuart Smith, National's MP for Kaikoura, and member of the Bluegreen Group.
