Economic and Environmental Challenges New Zealand in a Post Kyoto World Institute of Directors 11 September 2007 Post Kyoto Scenarios ► Scenario 1: No global deal to continue the Kyoto Protocol even in the medium term – Diplomatic efforts to reach agreement fail ► Scenario 2: A universally applicable deal is achieved under which: – All emissions are treated equally on a CO2e basis, irrespective of industry and country of source – Sequestration is treated as a negative emission on an equal footing – The cap for each country is set relative to GDP 2 Post Kyoto Scenarios ► Scenario 3: A Kyoto-type deal is concluded under which: – Developed economies are subject to an absolute cap – Developing economies are not subject to any cap ► Scenario 4: A two-tier deal is concluded under which: – Developed economies are subject to a cap related to GDP – Developing economies are subject to a cap related to GDP but with a higher level of emissions permitted 3 Environmental and Economic Challenges ► Scenario 1: – Climate change impact on NZ • ?? • If accept scientists then warmer, wetter in west and drier in east, more violent fluctuations, some sea level change • Relatively moderate for NZ because of maritime effect – Economic impact on NZ • NZ agriculture will need to adjust locations and methods but it is used to doing that • Some impact on coastal and other property risks and costs (ChCh?) • Need for better, rational water management (ChCh?) • Growing demand for our products especially from Australia 4 Environmental and Economic Challenges ► Scenario 2: – Climate change impact on NZ • Moderated – Economic impact on NZ • No competitiveness at risk issues • Low carbon footprint of our agricultural production will mean it is advantaged world-wide • NZ may have comparative advantage in forest sequestration • International tourism likely to suffer as visiting NZ carbon intensive. Domestic tourism likely to get boost • Transport costs generally likely to rise • Overall in medium term not likely to be a great impact on NZ income levels or growth 5 Environmental and Economic Challenges ► Scenario 3: – Climate change impact on NZ • Effectively same as for Scenario 1 but may actually be worse • What will change is where emissions come from in the world. More from developing economies – Economic impact on NZ • Major competitiveness at risk issues for our export oriented and import competing economic activities • Industries and agricultural production will over time leak overseas to developing economies • Significant impact on NZ income levels and growth prospects 6 Environmental and Economic Challenges ► Scenario 4 – A mixture between scenarios 2 & 3 – Where in the spectrum will depend on how close the cap for developing economies is to the cap for developed economies – If similar caps, then impact likely to be close to scenario 2 – If dissimilar caps, then impact likely to be close to scenario 3 7 Implications ► The economic impact on NZ will depend much on the nature of the deal so we need to mount a major diplomatic effort ► My suggestions are based on my thinking about the situation. Solid research using complex general equilibrium modelling to help us understand the likely impacts of various alternative deals is essential ► If I am right, NZ should be pushing for “all in” and at most concede minimum concessions to developing economies 8
