From: Andrew Riddell
Dear Simon Watts,
Radio New Zealand reports that the government have rejected recent recommendations from the Climate Change Commission over methane emission levels and the 2050 emission target.
It reported that the rejection was based on analysis showed that following the Climate Commission's recommendations would come at an economic cost to Aotearoa New Zealand - "Modelling indicates that GDP would be 0.4 percent lower than the status quo in 2035, and 2.2 percent lower in 2050."
Please provide copies of the modelling referred to, include all assumptions made with respect to assessing the impact of cost of the recommended emissions reductions on GDP and with respect to assessing the impact on GDP of not following the Climate Commission's recommendations these impacts would include the modelled GDP reduction arising from climate change enhanced storm events, droughts and sea level rise until 2050).
Ngā mihi,

about an issue, then your email will be passed to his electorate office.
· Invitations and requests to meet with the Minister will be
considered and a staff member will be in touch with you in due course.
· Requests for official information will be managed in accordance
with provisions of the Official Information Act 1982, which may include a
transfer to a more relevant Minister or agency.

responsibilities, expresses a personal view, or is copied to multiple
Members of Parliament, then your opinion will be noted and your
correspondence may be transferred to another office, or there may be no
further response to you.
