This document discusses direct air capture (DAC) of carbon dioxide from the atmosphere as a way to reverse climate change. It notes that CO2 levels have risen significantly since the Industrial Revolution and that CO2 is the largest contributor to greenhouse gas emissions. The document reviews different approaches to CO2 removal and explains that DAC is needed to capture emissions from scattered sources. It then discusses the importance of the work, identifies gaps in current research on DAC, and outlines the objectives, timeline, and expected outcomes of simulating a 1 ton/day DAC process on Aspen Plus to provide a cost analysis. Commercialization opportunities and social impacts of DAC are also summarized.

Direct Air Capture of Carbon dioxide - FYP 2021 - DChE - GIK Institute
This document describes a process for direct air capture of carbon dioxide using aqueous potassium hydroxide (KOH) as the absorbent. The process involves absorbing CO2 from air in an air contactor, producing potassium carbonate, which is then reacted with calcium hydroxide to produce calcium carbonate pellets. These pellets are heated in a calciner to release pure CO2 while regenerating the sorbents for reuse. Material and energy balances are presented for each unit showing that over 1 million tons of CO2 could be captured per year using this process.

This document summarizes a study assessing the role of bioenergy with carbon capture and storage (BECCS) in helping the UK achieve its future low-carbon energy and emissions reduction targets. The study uses a UK energy systems model to explore scenarios with different levels of bioenergy availability and BECCS deployment. The results show that BECCS plays a crucial role in decarbonizing the electricity sector but its uncertainty significantly impacts overall decarbonization costs. Achieving net-zero emissions by 2050 is only possible with BECCS deployment or carbon capture and storage after 2040, but delaying these technologies requires extreme electrification levels, especially in industry. Higher bioenergy availability and earlier BECCS deployment reduce costs

Public Administration Presentation Waste Reduction Programme[1]
The document summarizes Hong Kong's current municipal solid waste disposal problem and policies. The three existing landfills will be full by 2010, so Hong Kong must choose between expanding landfills or adopting incineration. Incineration would reduce waste volume by 90% and generate electricity, but faces opposition over pollution concerns. A political, economic, social and technological analysis is provided of the options. Suggestions include consulting foreign experts and reducing waste through the 3R approach of reduce, reuse and recycle.
Taiwan announced INDC target voluntarily to combat climate change
Taiwan has committed to reducing greenhouse gas emissions by 50% from projected business-as-usual levels by 2030 in its Intended Nationally Determined Contribution. This targets a reduction to 214 million tons of CO2 equivalent emissions by 2030, down from a projected 428 million tons if no action was taken. Taiwan considered factors like future economic and population growth, existing emissions reduction policies, and targets set by other countries in determining its 2030 target. The target will help Taiwan meet its long-term goal under domestic law of reducing emissions 50% below 2005 levels by 2050.
Deshraj Singh Suman
This document discusses the interactions between agriculture and the environment in India. It notes that agricultural productivity has greatly increased since the Green Revolution through high-yielding varieties, irrigation, and increased chemical use. However, this has also led to various environmental issues. Climate change is causing rising temperatures, uncertain rainfall patterns, and more extreme weather. Agricultural activities like rice cultivation, livestock, and fertilizer use contribute significantly to greenhouse gas emissions. Water resources are being polluted by industrial and agricultural runoff containing chemicals, sediments, and fertilizers. Soil quality is declining due to loss of organic matter, erosion, nutrient imbalances, compaction, salinization, and contamination from pesticides. These environmental changes and degradation are negatively impacting agricultural
William Moomaw - Climate Advocacy: From Grassroots Activism to International ...
This document discusses the need to rebuild soils and ecosystems to help mitigate climate change. It notes that 2300 gigatons of carbon is stored in soils. Strategies proposed include rapidly reducing fossil fuel use and avoiding releasing carbon from soils, as well as accelerating carbon uptake through restoring forests, grasslands, wetlands and soils. Aggressive sequestration through these natural solutions could boost net removals from the atmosphere and help balance carbon dioxide levels sooner. The document emphasizes that a restored global biosphere is needed to accelerate removing carbon dioxide from the atmosphere, as oceans alone cannot do this, and restoring natural ecosystems is an essential imperative.
Environment and climate trends (co2)
Global carbon dioxide emissions increased significantly in 2010 after declining in 2009, pushing atmospheric CO2 concentrations higher. CO2 levels are now 45% above pre-industrial levels and account for over 70% of global greenhouse gases. The energy sector, particularly coal combustion, represents the largest source of CO2 emissions. While some developed countries have reduced emissions from 1990 levels in accordance with the Kyoto Protocol, other countries like Canada, Australia and the US will not meet their targets. Carbon capture and storage is being developed and tested to reduce emissions from fossil fuel use but currently only operates at a very small scale globally.

The document discusses shale gas reserves, regulation, and water demand in the UK. It summarizes that the UK imports most of its natural gas and shale gas reserves could help improve energy security. Shale gas extraction requires significant amounts of water, raising concerns about potential water stress. The regulatory framework for shale gas exploration and drilling is still being developed to help manage environmental risks.
6. global warming
The document discusses the main greenhouse gases that cause global warming: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. These gases are emitted through human activities like burning fossil fuels, decomposition of waste, industrial processes, and agriculture. Since the industrial era, atmospheric levels of carbon dioxide, methane and nitrous oxide have increased significantly due to human activity. Individuals in the US are responsible for emitting around 6.6 tons of greenhouse gases per year on average, with most emissions coming from fossil fuels used for electricity and transportation. Global warming is expected to have wide-ranging impacts on health, water resources, coastal areas, agriculture and ecosystems worldwide if emissions continue rising
'Drowning Earth' - Magazine-style report on Climate Change. - Data Visualization
The document discusses climate change and global warming trends based on data from EU countries. It finds that the largest contributors of greenhouse gases in the EU are Germany, France, the UK, and Italy, together accounting for over 50% of emissions. While emissions from most large countries have leveled off or decreased slightly since 1990, Turkey's emissions continue to rise steadily. The energy sector produces the most greenhouse gases, followed by transportation, industry, and agriculture. Renewable energy consumption has increased substantially globally since 1997 but more investment is still needed to meet rising energy demands. Projections estimate natural gas and renewables will grow significantly as electricity sources through 2050.

Bridging gaps between policymaking and science: the case of global forest car...Integrated Carbon Observation System (ICOS)
This document summarizes a presentation about reconciling estimates of global forest carbon fluxes between policy and science. It discusses how the IPCC and country greenhouse gas inventories estimate land use emissions differently, creating a large gap. The presentation proposes that the IPCC disaggregate its estimates to make them more comparable to country data by separating direct and indirect human and natural effects. It also suggests assessing the implications of reconciled estimates for the Paris Agreement goal of limiting warming to 2°C. Reconciling the data sources would help provide a common understanding for the Agreement's Global Stocktake reviews.The role of PtXin meeting the 2 and well below 2 °C mitigation targets
The document discusses the role of power-to-gas (PtG), power-to-liquids (PtL), and power-to-X (PtX) technologies in meeting climate mitigation targets. It analyzes two case studies: 1) how PtX can help Finland reduce greenhouse gas emissions 80-95% by 2050 through biomass and hydrogen utilization, and 2) how global adoption of PtX, direct air capture, and decarbonized fuels can allow the world to phase out fossil fuels by 2100 and meet a 1.5°C target. The analysis finds that PtX can play an important role in increasing renewable energy shares after 2040 by providing seasonal energy storage. Globally, Pt

Nitrogen deposition dose: Response relationships for habitats - Dr Chris Fields
Semi-natural habitats in Britain and, indeed, most highly populated world regions are threatened by aerial deposition of reactive nitrogen compounds, largely emitted from the processes of intensive agriculture, vehicles and power generation. We have been slow to understand the potential significance of the increased exposure and accumulation of nitrogen in the ecological system. Numerous research studies from varied habitats in different countries indicate that the composition and biodiversity of plant communities is adversely affected at even low levels of exposure and impacts may extend beyond the plant kingdom to other trophic levels such as butterflies and birds. Furthermore, the likelihood that negative change in habitats can be easily reversed is now being questioned due to the longevity of accumulated nitrogen in the ecosystem. This paper will discuss the main effects of nitrogen compounds and the nature of the dose response between nitrogen and ecological harm.
Global warming
This document discusses scenarios for global carbon emissions and climate change mitigation over the next 100 years. It begins with background on historical emissions and projections for peak production of oil, gas, and coal. Unmitigated emissions would result in a doubling of atmospheric CO2 levels by 2100. Implementing stabilization "wedges" through strategies like renewable energy and efficiency could significantly reduce emissions. Modeling shows that applying 3 wedges cuts coal emissions to zero by 2100 and keeps atmospheric CO2 increases lower.

Greenhouse Gas Emissions in Ireland – Trends and Projections
Greenhouse Gas Emissions in Ireland – Trends and ProjectionsEnvironmental Protection Agency, Ireland
1) The EPA is responsible for producing Ireland's national greenhouse gas emission inventories and projections, which are submitted to the EU and UN.
2) Ireland's greenhouse gas emissions increased by 27% between 1990-2010 but have decreased by 9% from their peak in 2000. Emissions from the energy sector contribute the most.
3) Ireland is projected to exceed its 2020 EU target for reducing emissions in the non-trading sector (transport, buildings, agriculture, waste) by 20% compared to 2005 levels. Focus is needed on policies and measures to reduce emissions from agriculture and transport.What We Feed Dairy Cattle Impacts Manure Chemistry and the Environment
For more: http://www.extension.org/67674 During the last part of the 20th century, animal manure management became an environmental concern. In response to these concerns, legislation was enacted to control manure management and the emission of undesirable gasses (e.g., methane, ammonia, nitrous oxide) from animal production systems. The purpose of this paper is to illustrate how mineral phosphorus (P) supplements, forage types and amounts, and the crude protein (CP) fed to lactating cows impact manure chemistry and the fate of manure nutrients in the environment.

Greenhouse Gas Emissions in Ireland – Trends and Projections
Greenhouse Gas Emissions in Ireland – Trends and ProjectionsEnvironmental Protection Agency, Ireland
1) The EPA is responsible for producing Ireland's national greenhouse gas emission inventories and projections, which are submitted to the EU and UN.
2) Ireland's greenhouse gas emissions increased by 27% between 1990-2010 but have decreased by 9% from their peak in 2000. Emissions from the energy sector contribute the most.
3) Ireland is projected to exceed its 2020 EU target for reducing emissions in the non-trading sector (transport, buildings, agriculture, waste) by 20% compared to 2005 levels. Focus is needed on policies and measures to reduce emissions from agriculture and transport.What We Feed Dairy Cattle Impacts Manure Chemistry and the Environment
For more: http://www.extension.org/67674 During the last part of the 20th century, animal manure management became an environmental concern. In response to these concerns, legislation was enacted to control manure management and the emission of undesirable gasses (e.g., methane, ammonia, nitrous oxide) from animal production systems. The purpose of this paper is to illustrate how mineral phosphorus (P) supplements, forage types and amounts, and the crude protein (CP) fed to lactating cows impact manure chemistry and the fate of manure nutrients in the environment.
Contribution of greenhouse gas emissions: animal agriculture in perspective

Carbon dioxide, methane and nitrous oxide emissions from an oil palm plantati...
Although nitrous oxide only makes up 8% of global greenhouse gas emissions, it has nearly 300 times the global warming potential of carbon dioxide. In this presentation, CIFOR scientist Kristell Hergoualc’h explains results from collaborative research between CIFOR, ICRAF, CIRAD and PT Bakrie, which show that nitrogen fertiliser can exacerbate the production of soil nitrous oxide greenhouse gases when applied to oil palms grown on deep peat. She gave this presentation on 23 February 2012 at the International Conference on Oil Palm & Environment (ICOPE) held in Bali, Indonesia. The conference had the theme ‘Conserving forest, expanding sustainable palm oil production’.
Nitrous oxide
Nitrous oxide is an inhaled sedative that provides anxiolysis and analgesia for brief medical procedures. It works quickly by crossing the blood-brain barrier and is eliminated rapidly through exhalation. Potential side effects include nausea, vomiting, and diffusion hypoxia if not administered properly. Safety considerations include contraindications for patients with conditions involving trapped gas and ensuring adequate oxygenation when the nitrous oxide is discontinued. Nurse administration of nitrous oxide requires monitoring vital signs and scavenging expired gases.

Lecture: The world over we create a lot of bio degradable waste. Many of our traditional methods of dumping these wastes into seas of hole in the ground are closing. We need better and we need to take care of the environment. Life Cycle Assessment (LCA) is a 'systems theory' method that accounts for the environment by taking a cradle to grave view of changed products and processes and accounting for all inputs and outputs across the system boundary. I present case studies and some of the ideas and insights in modelling them and what has been learned about the systems

On soil carbon sequestration to mitigate climate change: potentials and drawb...
Carbon sequestration in soils has potential to mitigate climate change but also drawbacks. While increasing soil organic carbon could be considered sequestration, it must result in a net transfer of carbon from the atmosphere to land. Options to sequester carbon include converting arable land to grassland or forest, but this may displace agriculture elsewhere. Maintaining or increasing soil carbon through reduced tillage, cover crops or organic amendments provides other benefits but may not genuinely sequester new carbon. Overall, too much focus on soil carbon risks neglecting larger climate threats, and priorities should be good land stewardship and integrated solutions.

The presentation is divided in two parts (Part A & Part B). Part A presents global factors, data and environmental aspects related to waste management while Part B identifies local actions on waste management with global effects.
Impact of carbon sequestration on soil and crop productivity
This document discusses the impact of carbon sequestration on soil and crop productivity. It provides background on global carbon emissions and pools. Soil acts as both a source and sink of atmospheric carbon through processes like photosynthesis, respiration, and decomposition. Improving soil organic carbon through practices like conservation tillage, cover crops, nutrient management, and agroforestry can increase crop yields by improving soil quality properties. Maintaining or increasing soil organic carbon levels through appropriate land management practices helps mitigate climate change while enhancing soil health and agricultural productivity.
Advantages of glyphosate in conservation agriculture conditions
This document summarizes the advantages of glyphosate and conservation agriculture practices. Conservation agriculture aims to achieve sustainable agriculture through minimal soil disturbance, permanent soil cover, and crop rotations. It can help reduce soil erosion, increase water retention, improve soil carbon levels, reduce energy usage and labor needs, and increase yields. Adopting conservation agriculture practices can benefit farmers through lower costs and higher profits while also providing environmental benefits such as reduced greenhouse gas emissions and water pollution.
Presentation TEAGASC
This document summarizes a study measuring carbon dioxide (CO2) flux from Irish grasslands to determine their potential as carbon sinks. The study found that a grassland site in Cork sequestered 1.2 tons of carbon per hectare per year in soil, making it a carbon sink for 8 months annually. However, interannual sequestration varied significantly between 2.2 to 3.7 tons of carbon per hectare per year. While lower than forestry, preliminary results suggest Irish grasslands may provide opportunities for carbon sequestration through soil storage.

6. global warming
The document discusses global warming and greenhouse gas emissions. It identifies the primary greenhouse gases as carbon dioxide, methane, and nitrous oxide which are emitted through activities like burning fossil fuels and agriculture. Global greenhouse gas concentrations have increased significantly since the industrial revolution due to human activity. This is causing the planet to warm with impacts like changes in temperature, effects on ecosystems and health, and risks to water resources, agriculture, and coastlines. Reducing emissions from sources like energy production and transportation can help mitigate further global warming.

Myles Allen
1) Methane emissions do not need to reach zero to stop additional global warming, as methane does not accumulate in the atmosphere like carbon dioxide.
2) The impact of methane emissions on temperature depends on both cumulative emissions and annual emission rates, unlike carbon dioxide where only cumulative emissions matter.
3) Treating methane and carbon dioxide as equivalent based solely on their 100-year global warming potential fails to capture their different impacts on temperature over time. Factoring in annual emission rates provides a better comparison.
Dieter Helm
This document is a list of 6 papers written by Dieter Helm between 2015-2017 on various topics related to natural capital and the environment. The papers include topics such as waste policy, flood defence, green bonds, agricultural policy after Brexit, catchment management and abstraction, and defending the green belt. All papers were published as part of Dieter Helm's Natural Capital Network.
Minette Batters
This document discusses the United Kingdom's goal of achieving net zero carbon emissions by 2050 and how the agricultural industry can help meet that target. It outlines strategies for agriculture to become more efficient and sustainable, such as improving soil health, using new farming practices, and deploying technologies that increase productivity while reducing environmental impact. The document also presents the specific plans and initiatives one farm, Barford Park, is taking to reach net zero emissions by changing its practices around livestock, manure, and renewable energy.
Gail Bradbrook
This document discusses the threats of climate change and extinction. It notes that a Permian-Triassic extinction event was caused by runaway climate change and methane releases, wiping out 97% of life. It warns that 1°C of warming will reduce economic growth by 1% and crop yields by 10%, and that at 2.5°C the world will not be able to produce enough calories to feed the population. Experts say societal collapse is inevitable and human extinction is possible if climate change is not addressed. Extinction Rebellion was launched in 2018 to truthfully address the climate crisis through non-violent civil disobedience and demand net-zero emissions by 2025.
Charles Massy
The document discusses regenerative agriculture as a solution to the environmental damage caused by industrial agriculture. It summarizes the history of agriculture as a series of transformations that increased productivity but also caused environmental degradation. Regenerative practices like holistic grazing management, cover cropping, and permaculture can help repair landscapes by restoring healthy soil, water cycles, and biodiversity. This represents an eighth transformation to a more sustainable model of agriculture.
Professor Michael lee
This document discusses sustainable agriculture and the role of livestock in food security. It presents several metrics for comparing the sustainability of different livestock production systems and meat types, including their nutritional quality, greenhouse gas emissions, arable land use, and impacts on soil health. Several key points are made: (1) Grass-fed beef production provides meat with higher nutritional quality than concentrate-fed beef in some metrics; (2) Accounting for nutritional quality can change the rankings of production systems based on metrics like greenhouse gas emissions; (3) Different livestock have varying impacts on metrics like arable land use and nutrient provision per unit of land. The document advocates developing nuanced, "fit-for-purpose" metrics to properly evaluate livestock's
Understanding Fats - Richard Young
This document discusses the history of dietary recommendations to reduce saturated fat and consume more vegetable oils. It notes that in the early 20th century, consumers were encouraged to switch from animal fats to vegetable oils and saturated to polyunsaturated fats. However, despite these dietary changes, rates of heart disease, obesity and diabetes have increased. The document questions whether vegetable oils are better for health or the environment than animal fats. It summarizes the evidence that linked saturated fat to heart disease and promoted vegetable oils may have been influenced by the sugar industry.
David Mermin - Communications
Voters are concerned about the current food system and want changes to make healthy food more affordable and accessible. They support limiting subsidies to large farms and providing incentives for sustainable farming. Messaging framing the goal of the food system as health rather than profit finds widespread agreement across all voter groups. A national survey of 1,000 voters was conducted to understand these views.
Dana Gunders - Waste
The document discusses facts about food waste in the United States. It notes that 40% of food goes uneaten, costing $162-218 billion annually. This waste has serious environmental impacts, equivalent to 141 trillion calories and 8 million New York to San Francisco car trips in greenhouse gas emissions from uneaten turkey over Thanksgiving. Solutions proposed include reforming confusing food date labels, identifying model policies, and educating consumers to reduce food waste by 50% by 2030. Individual actions people can take include reducing their own waste.
Dana Frasz - Waste
Americans throw out $218 billion worth of food each year while hunger costs the nation $168 billion. The biggest challenges to food recovery are infrastructure and capacity, sector innovation and cross-sector collaboration, inefficient distribution, and nutritional deficiencies. Key principles for a sustainable food recovery sector include commitment to innovation, increasing capacity and infrastructure before more donations, financially sustainable social enterprises, community-driven solutions, and ensuring high-quality nutritious food while recognizing food alone cannot solve hunger.
Seth Watkins - Integrated farming systems
This document discusses the benefits of diversifying a farm through integrated crop and livestock systems compared to specialization. It outlines some of the economic and social barriers farmers face in making this transition. Specific examples are provided showing the cost savings and increased production from practices like cover cropping and grazing livestock compared to traditional chemical-dependent systems. The benefits of taking a holistic, long-term approach to the farm as an ecological system are discussed.
Kim Lyerly - CAFOs
The study analyzed health outcomes in populations living in 17 North Carolina counties with concentrated animal feeding operations (CAFOs) housing over 100,000 hogs, compared to populations in 40 counties without hog CAFOs. After adjusting for demographics and socioeconomic factors, the study found higher rates of emergency department visits and hospital admissions in CAFO counties for several diseases, including infectious diseases (30% increase), respiratory diseases (20% increase), hypertension (30% increase), diabetes (70% increase), kidney diseases (30% increase), complications of pregnancy (25% increase), and epilepsy (70% increase). Mortality rates were also higher in CAFO counties for some of these conditions. The results suggest vulnerable populations like children and

Antibiotic use in animal agriculture may be responsible for many resistant human infections, but quantifying this burden is challenging due to lack of data. Key data needed includes detailed antibiotic use patterns in animals, molecular characterization of bacteria from food animals and surrounding environments, and bacteria from human infections. While techniques exist, current monitoring programs are limited and do not systematically collect this information. Expanding data collection through strengthened federal programs could help assign an evidence-based burden from agricultural antibiotic misuse.

Viney P. Aneja's presentation discusses pollution and emissions from concentrated animal feeding operations (CAFOs) in the United States. It notes that ammonia makes up the largest volume of agricultural emissions in the US and contributes to particulate matter formation and nitrogen deposition. The presentation analyzes case studies that show how ammonia emissions can influence exceeding particulate matter air quality standards. It also examines the impacts of ammonia on climate change through increased nitrous oxide and impacts on the nitrogen cycle. The presentation concludes by calling out challenges for regulating ammonia and encouraging mitigation strategies to reduce agricultural emissions.
Whendee Silver - Soil
This document summarizes research on managing grasslands to mitigate climate change through carbon sequestration. It finds that:
1) Grasslands store large amounts of carbon in soils, and practices like applying livestock manure or compost can significantly increase soil carbon storage for decades or more, offsetting greenhouse gas emissions.
2) Managing half of California's grasslands to increase soil carbon by 0.5 metric tons per hectare per year could offset 21 million metric tons of CO2 equivalents annually.
3) Projects demonstrating increased soil carbon through compost and manure in California grasslands show the potential for agriculture and soil management to meaningfully contribute to climate change mitigation.

Stay Ahead of the Curve with PFAS Testing
There is a tremendous amount of news being disseminated every day online about dangerous forever chemicals called PFAS. In this interview with a global PFAS testing expert, Geraint Williams of ALS, he and York Analytical President Michael Beckerich discuss the hot-button issues for the environmental engineering and consulting industry -- the wider range of PFAS contamination sites, new PFAS that are unregulated, and the compliance challenges ahead.
Widespread PFAS contamination requires stringent sampling and laboratory analyses by certified laboratories only -- whether it is for PFAS in soil, groundwater, wastewater or drinking water.
Contact us at York Analytical Laboratories for expert environmental testing with fast turnaround times and client service. We have 4 state-certified laboratories in Connecticut, New York and New Jersey, and 4 client service centers.

Lessons from operationalizing integrated landscape approaches
Presented by James Reed at "9th Landscape Sustainability Science Forum" on 11 May 2024
(Q)SAR Assessment Framework: Guidance for Assessing (Q)SAR Models and Predict...
The webinar provided an overview of the new OECD (Q)SAR Assessment Framework for evaluating the scientific validity of (Q)SAR models, predictions, and results from multiple predictions. The QAF provides assessment elements for existing principles for evaluating models, as well as new principles for evaluating predictions and results. In addition to the principles, assessment elements, and guidance for evaluating each element, the QAF includes a checklist for reporting assessments.
This new Framework provides regulators with a consistent and transparent approach for reviewing the use of (Q)SAR predictions in a regulatory context and increases the confidence to accept alternative methods for evaluating chemical hazards. The OECD worked closely together with the Istituto Superiore di Sanità (Italy) and the European Chemicals Agency (ECHA), supported by a variety of international experts to develop a checklist of criteria and guidance for evaluating each criterion. The aim of the QAF is to help establish confidence in the use of (Q)SARs in evaluating chemical safety, and was designed to be applicable irrespective of the modelling technique used to build the model, the predicted endpoint, and the intended regulatory purpose.
The webinar provided an overview of the project and presented the main aspects of the framework for assessing models and results based on individual or multiple predictions.
