A crucial factor in the success of any water quality trading market is its ability to cost-effectivelyreallocate nutrient allowances from initial holders to those users who find them most valuable;the market's trading efficiency. We explore causes of and solutions to trading inefficiency...

An auction of carbon permits is the best way to achieve carbon caps set by international negotiation to limit global climate change. To minimize administrative costs, permits would be required at the level of oil refineries, natural gas pipe lines, liquid sellers, and coal processing plants. To...

Voluntary opt-in programs to reduce emissions in unregulated sectors or countries have spurred considerable discussion. Since any regulator will make errors in predicting baselines and participants will self-select into the program, adverse selection will reduce efficiency and possibly...

The allocation of permits is an important design aspect of an emissions trading scheme. Traditionally, governments have favoured the free allocation of greenhouse gas permits based on individual historical emissions (‘grandfathering’) or industry benchmark data. Particularly in the European...

Under the New Zealand Emission Trading System (NZETS), post-1989 forestry land (the exotic or indigenous forest land that was not used for plantation on 31 December 1989) in New Zealand is eligible for reward for each tonne of CO2-eqv sequestrated by reverting from pasture to indigenous scrub....

We consider two approaches to quantify New Zealand farmers’ ability to mitigate their farm’s environmental impact: The construction of marginal abatement cost curves and improvements in farm management practices. Marginal abatement cost curves can be constructed by combining information on...

The intensity of agricultural production affects both nutrient and greenhouse gas emissions. Environmental policy designed to reduce one type of pollution may have complementary effects on the other type. This paper explores this issue in the Lake Rotorua catchment in New Zealand using an...
