The Institute for Policy Integrity calls on the EPA to revise outdated New Source Performance Standards for nitric acid plants, specifically requesting updated NOx standards based on cost-benefit analysis and the inclusion of nitrous oxide (N2O) as a regulated pollutant due to its impact on public health and the climate.

CDM Watch and partner organizations are calling on EU Environment Ministers to ensure that HFC-23 and adipic acid (N2O AA) offset credits are banned from national registries for non-traded sectors by April 2013. While these credits are banned from the EU Emissions Trading System (EU ETS) as of 30 April 2013, the authors argue that the Effort Sharing Decision (ESD) could be exploited to allow their use toward national targets, undermining domestic emissions reductions and the Montreal Protocol.

The document details California's efforts to reduce greenhouse gas emissions to 1990 levels by 2020 under the Global Warming Solutions Act of 2006 (AB32). It outlines a cap-and-trade program scheduled for January 2012, alongside 'early action' measures such as the Low Carbon Fuel Standard and landfill methane capture. The briefing also highlights California's leadership in the Western Climate Initiative and the political support for these measures following the defeat of Proposition 23 in November 2010.

The Resources and Energy Analysis Programme (REAP) is an environmental analysis tool that uses an environmentally extended input-output model to assess the global environmental impact of consumption at national, regional, and local levels. It tracks greenhouse gases, ecological footprints, and energy sources across the entire life cycle of products and services, including imports. The tool includes a scenario function to model the effects of political decisions, population changes, and shifts in consumption or transport habits. Originally developed in the UK in 2006, a Swedish version was introduced in April 2011.

The study finds that the CDM successfully incentivized N2O abatement in the nitric acid sector, where such practices were previously rare. While the risk of carbon leakage and systematic baseline manipulation is judged to be low for nitric acid projects—especially compared to adipic acid projects—the authors highlight significant issues with current methodologies. These include complexity leading to credit issuance delays and a system that rewards high-emitting plants. To resolve these, the authors recommend implementing a benchmark factor for baseline emissions, potentially in the range of 4 to 5 kg N2O per tonne of nitric acid.

The paper finds that CDM nitric acid projects have successfully fostered abatement in a sector that previously lacked such practices, with limited risk of carbon leakage and no evidence of systematic baseline manipulation. However, it highlights significant variability in baseline emissions between plants and monitoring periods, and notes substantial delays in credit issuance, particularly for projects using secondary abatement (AM0034). The authors recommend transitioning to a common benchmarking approach for baseline emissions to simplify methodologies, reduce transaction costs, and ensure environmental integrity.

The research finds that while the CDM successfully drove N2O abatement efficiencies to 98-100%, it created significant competitive advantages for registered plants. This led to carbon leakage during 2008 and 2009, where production shifted from plants in industrialized countries or those with existing abatement to CDM plants. The authors estimate that approximately 13.5 MtCO2e of issued CERs for 2008 and 2009 did not represent real emission reductions. To mitigate this, the paper recommends implementing ambitious baseline emission benchmarks in the CDM methodology.

The report analyzes how the Canadian agricultural sector can contribute to greenhouse gas reductions and the economic implications of emerging climate policies. It highlights the potential for carbon sequestration in soils and the role of bioenergy, while discussing the complexities of implementing a national cap-and-trade system. Key concerns include the integrity of agricultural offsets, the risk of carbon reversal, and the impact of international trade rules and U.S. policy alignment on Canadian competitiveness.

The report assesses whether genetic engineering can reduce nitrogen fertilizer pollution by improving nitrogen use efficiency (NUE) in crops. It finds that while some GE genes show promise in controlled environments, no GE NUE crops have been commercialized, and they may cause unpredictable side effects. In contrast, traditional breeding has a proven track record of improving NUE, and ecosystem-based methods like cover crops and precision farming offer complementary ways to reduce nitrogen loss. The authors argue that a multi-pronged approach, supported by increased public investment in non-GE methods, is necessary to feed a growing population while mitigating environmental damage.

The report assesses whether genetic engineering (GE) can reduce the environmental impact of reactive nitrogen in agriculture. It finds that while GE research is ongoing, no NUE-improved GE crops have been commercialized, and their prospects remain uncertain due to complex gene interactions and potential regulatory hurdles. In contrast, traditional breeding and system-based approaches like cover crops and precision farming have already demonstrated significant improvements in NUE and nitrogen loss reduction. The authors argue that a diversified approach, supported by increased public investment in non-GE methods, is essential to mitigate global nitrogen pollution.

The document examines the environmental benefits and risks of pulse production in Canada, focusing on the information systems that track these impacts from the farm to the federal level. It highlights the role of nitrogen-fixing pulses in reducing synthetic fertilizer use and the shift toward conservation tillage to combat soil erosion. The analysis identifies a gap between informal, farm-level observations and formal, aggregated government data, noting that proprietary soil-testing data and political boundaries between provinces hinder a fully integrated information infrastructure.

The study uses the SIMSDAIRY and LEGGRAZE models to project the impact of climate change on UK dairy systems across four time-slices (baseline, 2020s, 2050s, and 2080s). Findings indicate a general decrease in nitrous oxide (N2O) and overall greenhouse gas (GHG) emissions per litre of milk, but an increase in ammonia (NH3) emissions and nitrate (NO3) concentrations in leachate. While farm profitability and soil quality are projected to improve due to increased land productivity and altered rainfall patterns, the study highlights a trade-off with increased acidifying gases and water pollution.

The report projects that Wisconsin will face significantly hotter summers, increased flooding, and agricultural disruptions if current emissions trends continue. Under a high-emissions scenario, Milwaukee could see more than 55 days per summer over 90°F by the end of the century. The document advocates for a transition to clean energy through renewable electricity standards, energy efficiency, and federal cap-and-trade policies to mitigate these risks.

In 2005, total global anthropogenic greenhouse gas emissions were estimated at 44,153 MtCO2 equivalent, representing a 12.7% increase from 2000. The energy sector, specifically electricity, heat, and transportation, drove much of this growth, with developing countries accounting for the majority of emissions in electricity, heat, and industry. While high global warming potential gases grew by 44% between 2000 and 2005, they remain a small percentage of total emissions. Notably, revised methodologies for calculating land-use change reduced its estimated share of total GHGs from 18.2% to 12.2%, although actual emissions from this sector grew by 4.1% during the period.

The fact sheet describes biomass cofiring—the simultaneous combustion of biomass and a base fuel, typically coal—as a practical bridge to a renewable energy future. It highlights benefits including linear reductions in CO2 and SO2 emissions, lower capital costs for retrofitting existing boilers, and support for sustainable forest management by creating markets for hazardous fuels. However, it identifies barriers such as feedstock preparation costs and ASTM standards that prevent the sale of biomass-contaminated fly ash. The document suggests that replacing 5% of U.S. coal with biomass could reduce total U.S. emissions by 1.5% within 5-10 years.

The document outlines the potential for California farmers to benefit from the Global Warming Solutions Act (AB 32) through financial incentives, the sale of emissions offsets, and the production of bioenergy. It details specific strategies for reducing carbon dioxide, methane, and nitrous oxide, while noting that the California Air Resources Board (CARB) is tasked with developing the regulatory framework to meet 2020 emissions targets.

The report analyzes the 'hidden costs' of CAFOs, including taxpayer-funded subsidies and externalized environmental and health damages. It argues that CAFOs are not more efficient than medium-sized or pasture-based alternatives but are favored by government policies and the market power of large meat processors. The document details the pollution caused by manure, the rise of antibiotic-resistant pathogens, and the economic decline of rural communities, while proposing policy reforms to level the playing field for sustainable alternatives.

The study finds that CDM projects generally overestimate their emission reduction potential, with actual CER issuance reaching only 76% of the amount predicted at registration. Performance varies significantly by project type, with N2O projects over-performing (129%) and animal waste projects under-performing (28%). The analysis also indicates that in-house project development generally outperforms the use of large external consultancies, and that India showed the best host-country performance (122%) compared to China (55%) and Brazil (90%).

The study uses the Triple Bottom Line (BL3) software tool to analyze the environmental pressures of the Transport Equipment, Motor Vehicle, Hotels and Catering, Food and Drink, and Business Services sectors in South West England. It finds that for all five sectors, the largest source of CO2 emissions is associated with direct on-site operations. The Food and Drink sector has the highest overall emissions, while the Motor Vehicle sector is the most efficient per £ spent compared to UK averages. The report highlights that efficiency gains in industrial sectors could be outweighed by increased final demand for resources driven by regional growth and infrastructure projects.

The document serves as the first module of a foundation course on air quality management in Asia. It examines the primary drivers of urban air pollution, including fuel combustion from stationary sources and the significant impact of road traffic, particularly motorcycles and old diesel vehicles. It distinguishes between ambient, indoor, and transboundary air pollution, highlighting the severe health impacts of particulate matter (PM2.5) and the role of greenhouse gases in climate change. The text also assesses the air quality management (AQM) capabilities of 20 Asian cities, categorizing them from 'excellent' to 'limited'.
