| If agriculture is included in an Australian emissions trading scheme then it may face from 2015 at the earliest, a price for its greenhouse gas emissions; and thereby have incentives to offset and lessen its emissions. Yet because there is currently little understanding of the spatial pattern of emissions in agricultural regions of Australia, the extent of the challenge the sector faces in reducing its emissions is not fully recognised. To improve our understanding, this study uses the National Greenhouse Accounts methodology to estimate the spatial and temporal patterns of agricultural emissions since 1990 in the key agricultural region in Australia’s southwest. This region generates almost 40 percent of the nation’s winter crop production and supports... |

| 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 environmental integrity. In contrast, pure subsidies lead to full participation but require large financial transfers. We present a simple model to analyze this trade-off between adverse selection and infra-marginal transfers. We find that increasing the scale of voluntary programs both improves efficiency and reduces transfers. We show that discounting (paying less than full value for offsets) is inefficient and cannot be used to reduce the fraction of offsets that are... |

| Although it is common to alternate between till and no-till practices, past research has considered farmers’ tillage options to be limited to the dichotomous choice of whether or not to switch to a long-term no-till regime. This paper expands farmers’ options and models their choices of tillage frequency. Less frequent tilling sequesters more carbon but permits a greater accumulation of weeds, whereas more frequent tilling eliminates weeds but releases carbon (tillage emissions). The timing of tillage balances its marginal benefits and costs. Higher payments from industry or government for atmospheric greenhouse gas reductions will increase marginal cost and reduce tillage frequency. Other key parameters, such as higher rates of tillage emissions or... |

| The Queensland Government Environmental Offsets Policy provides an overarching framework for environmental offsets in Queensland. The policy provides a consistent and transparent approach to the use of offsets. It contains principles and guidelines for developing and applying more detailed ‘specific-issue’ policies for offsetting important environmental values such as vegetation or fish habitats. Currently, offsets use in Queensland can be characterised as a compliance mechanism as they are required to meet development conditions. Developers will face higher costs if they need an offset and this provides a greater incentive to avoid and minimise impacts on areas with significant environmental values. The paper canvasses opportunities to now move to develop... |

| Irrigation induced salinity is a serious problem in many countries around the world. In Australia, this type of salinity is most pronounced in the valley of the River Murray in South Australia. Location of irrigation enterprises has been identified as a key factor that needs to be taken into account by policies aimed at mitigating salinity. This article compares and contrasts two such policies: an irrigation zoning policy, where new irrigation enterprises are only allowed in low salinity impact zones, and an offsetting with salinity credits policy, where new irrigation enterprises can locate in high salinity impact zones, provided they offset their salinity impact with salinity credits. Key findings are that the offsetting policy will be both less costly... |

| This analysis estimates the profitability of restoring wetlands for the sale of carbon offsets. Results indicate that about 7% to 12% of the recently restored grassed wetlands of the prairie pothole and high plains regions and 20% to 35% of the forested wetlands of the Mississippi alluvial valley and Gulf-Atlantic coastal flats regions could have carbon offset values that exceed the cost of restoring the wetland and the opportunity cost of moving the land out of agricultural production. Given the uncertainties, the analysis applies conservative estimates of wetlands’ costs, offset prices, and wetlands’ effects on greenhouse gases. |
