Quebec hog producers' willingness to accept carbon credit revenue for adopting management practices that reduce greenhouse gas emissions

Guo, Yi, 1977- January 2007 (has links)
Canada's commitment to the Kyoto Protocol provides agricultural producers with an opportunity to supply carbon offset credits to a domestic carbon market and receive revenue from the sale of these credits. This study employed the multiple bounded discrete choice method to estimate Quebec hog producers' willingness to accept compensation to adopt two management practices that reduce carbon emissions; i.e. reduced protein feeding and adopting a manure storage cover. The average willingness to accept compensation for reduced protein feeding was $46.71 per tonne of CO2 equivalent and for the manure storage cover was $40.40 per tonne of CO2 equivalent. In addition, hog producers were asked what cost they would be willing to bear if they received $20 per animal unit in carbon offset credit revenue. The average cost they were willing to bear was $11.88. Key factors that influenced producers' decisions were identified. Results can be used to improve the institutional rules and public policy associated with developing a domestic carbon emission trading mechanism. Starting-point and sequencing bias were tested for with the convolution approach. Starting-point bias was found in all the hypothetical situations; while sequencing bias was not found.

Ontario feedlot operators' willingness to accept carbon credit revenue for adopting management practices that reduce greenhouse gas emissions

Hristeva, Polina. January 2007 (has links)
The Canadian agricultural sector was recognised as a potential seller of carbon offset credits in the domestic emission trading system. A number of beneficial management practices may reduce GHG emissions while increasing production efficiency and profitability of agricultural activities. A contingent valuation survey was used to estimate the carbon offset price at which feedlot operators in Ontario would adopt two management practices that reduce GHG emissions: adding roasted soybean seeds to a cattle diet and increasing the intensity of feedlot operations. The value elicitation questions to estimate the mean WTA compensation were designed using a multiple bounded discrete choice format developed by Welsh and Poe (1998). / It was estimated that at a carbon offset price of $ 25.14/t CO2 e provided enough incentive for feedlot operators to intensify their operations and a price of $ 109.51/t CO2e to change their feeding strategies. The mean willingness to accept a cost to change a conventional practice to a greenhouse gas emissions reducing practice was estimated to be 62% of the carbon revenue. The regression analysis demonstrated that producers' willingness to accept compensation was influenced by the individual's characteristics, farm structure variables, and practice attributes. Policy makers may use these results in the design of greenhouse gas reduction strategies for the beef sector.

Challenging Green Capitalism : An ideology Critique of Max Burgers' Environmental Strategies

Hedenqvist, Robin, Johansson, Hannah January 2018 (has links)
Environmental strategies implemented today are strongly influenced by the ideologies capitalism, neoliberalism and ecomodernism. As such, they should promote global economic expansion while mitigating environmental impact. This is in line with the prevailing environmental political discourse of sustainable development, in which economic, ecological and social dimensions are considered compatible and dependent on each other. However, this essay challenges the normative assumption regarding the win-win-win narrative by examining the economic, ecological and social consequences of Max Burgers’ environmental strategies through three critical scientific theories. By posing an ideology critique and through the lens of our theoretical framework, we find that Max Burgers mystifies the apparent relation between local economic growth, global ecological impact and divided social progress, thus reinforcing unequal power dynamics and patterns of uneven development.

Applications of Traditional and Concentrated Photovoltaic Technologies for Reducing Electricity Costs at Ontario Data Centers

Tomosk, Steven January 2016 (has links)
Demand for cloud-based applications and remote digital storage is increasing. As such, data center capacities will need to expand to support this shift in computing. Data centers consume substantial amounts of electricity in support of their operations, and larger data centers will mean that more energy is consumed. To reduce electricity bills, data center operators must explore innovative options, and this thesis proposes leveraging solar technology for this purpose. Three different photovoltaic and concentrated photovoltaic costing scenarios, as well as four different Ontario-based electricity tariff scenarios – time-of-use, feed-in tariff, power purchase agreement, and a peak-dependent electricity charge involving the province’s global adjustment fee – will be used to determine if there is a business case for using solar technology at data centers in Ontario to reduce energy costs. Discounted net present value, return on investment, internal rate of return, and levelized cost of electricity will be calculated to determine the economic viability of solar for this application, and both deterministic and stochastic results will be provided. Sensitivity of the four metrics to variability from energy yield, operations and maintenance costs, as well as system prices will also be presented.

Carbon emissions reduction and financial performance of Johannesburg Stock Exchange 's SRI companies

Worae, Thomas Adomah January 2017 (has links)
Thesis (Ph. D. (Accounting)) -- University of Limpopo, 2017. / This research examined the effect of carbon emissions reduction on financial performance Johannesburg Stock Exchange’s SRI companies. Empirical results of corporate fossil energy-based dependence on environment and economic performance thus far have been ambiguous. The major objective of this research was to examine the effect of emissions and energy intensity on market and accounting based performance measures. This research adopted the positivist paradigm approach and therefore used a quantitative causal research approach. Archival data was collected from fourteen JSE’s SRI companies for seven years. The research applied a panel data analysis, a total of 98 observations were derived from panel data set. Multiple linear and causal econometric models were applied in the data analyses namely ordinary least squares (OLS), fixed effects and dynamic models. OLS results showed a significant effect of energy usage intensity (ENGINT) on return on assets (ROA), and return on sales (ROS), with carbon emissions intensity (EMSINT) exhibiting a significant effect on return on assets (ROA), and return on sales (ROS). When the study controlled for omitted variable bias and possible orthogonality condition, a significant negative effect of energy intensity (ENGINT) on equity returns (EQRTNS) was found. Impulse response analysis revealed that shocks in energy intensity on average tend to decrease firms’ financial value, while shocks in emissions intensity on average increase firms’ financial value within the sampled companies. Whilst testing for causality, the Panel Granger causal analysis showed unidirectional effect of EMSINT on EQRTNS, and bidirectional causal relationship between EMSINT and MVE/S at 1% significant level. This research made a contribution by extending the model used by previous researchers through the use of multiple market and accounting based performance measures which were analysed using advanced econometric models: Arellano-Bond DPD model, impulse response function in short PVARs and Bootstrap dynamic panel threshold model. In addition, this thesis suggested a model to advance future research on carbon emissions and firm performance and managerial decision propensity for carbon reduction. / Carbon Disclosure Project and School of Accountancy of the University of Limpopo

REDD+ Projects Providing Sustainable Livelihoods for Rural Communities?  An Assessment of Voluntary Carbon Offsetting Projects in Peru and Tanzania

Tapping, Laura January 2020 (has links)
The voluntary carbon market, the area of focus for this thesis, developed alongside the compliance carbon market when individuals and organisations elected to compensate for their CO2 emissions. The steep growth in demand for voluntary carbon offset credits stemmed from the 2015 Paris Agreement. Climate issues were firmly on the agenda and carbon offsetting was viewed as a way for countries to meet their carbon reduction targets in efforts towards mitigating climate change. Since then, there has been a shift to natural climate solutions, namely forestry and land use carbon projects.  The ideal host location for such projects oftentimes have an existing, usually poor, population.  Project developers claim to help such populations by providing community benefits such as job creation and improved agricultural practices.  However, there is a gap in the research which focuses on the future of these communities after the projects, and how sustainable the benefits are.  This thesis examines the community benefits of two REDD+ (Reducing Emissions from Deforestation and Forest Degradation) projects: Alto Mayo Conservation Initiative, Peru and Yaeda Valley REDD Project, Tanzania.  Interviews with project developers are cross-referenced with project documents and other available sources to analyse the sustainability of the livelihood impacts.  The results show that the positive impacts of voluntary carbon projects on a local community can be sustained post-project. Overall, the well-being of community members can improve, as can decision-making skills and capacity levels.  Project participants can become more adaptable to shocks as their livelihoods have diversified and they have stronger links with international markets.  This link with international markets, however, can also become a barrier to livelihood benefits. As local people become reliant on market demand and project funds, they move away from subsistence farming and when demand drops, they may find it hard to prosper.  Additionally, there is a risk that following the departure of the project and its developers, more malevolent and powerful parties may move into the area.  To overcome these barriers, livelihood diversification opportunities need to be strengthened and land tenure issues clarified.

Investigating the feasibility of a locally developed carbon-offsetting scheme : the case of the Drifters Desert Nature Reserve

Gibson, Sean 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: In the context of both climate change and peak oil, it is clear that the tourism industry cannot continue with a business-as-usual approach. Unfettered fossil fuel use is no longer an option and novel approaches need to be explored in order to change the configuration of energy systems. Transport is particularly energy intense and consequently, since it involves travel, so is tourism. The Drifters Desert Nature Reserve (DDNR) is probably a net carbon sink. The property is large and has thousands of long lived trees and bushes: but this would be an ‘easy out’ in an industry which is has a reputation for evading tough questions. Are there affordable techniques that can be employed by the Reserve that will reduce its carbon footprint and enable it to move toward being entirely carbon neutral, without relying on sequestration? A willingness to pay (WTP) survey investigating if clients were prepared to pay a voluntary amount towards reducing the emissions of the DDNR, thereby offsetting some of their own emissions, was conducted; 121 questionnaires were completed. The results were extrapolated out to represent the WTP of the 1055 clients that visited the DDNR in the last year. It was found that 73% of all the clients who stay at the DDNR are willing to pay toward helping the DDNR change the way its systems are configured as a means to offset some of their own emissions debt in getting to the reserve. Lodge clients were prepared to pay almost double the amount clients staying at the campsite would consider. In both cases, WTP was around 10% of the value of the accommodation package chosen. The fossil fuel use and consequent carbon dioxide debt of the DDNR was calculated and emissions were found to be in the region of 30 tonnes per annum. As per the case in the greater Namibia, transport is responsible for the bulk of the carbon dioxide output, with energy provision in this off-grid reserve being a close second. Of four potential interventions considered, two were found to be financially viable, regardless of the WTP of clientele. It is speculated that WTP on a small scale is administratively laborious and the potential contribution of a voluntary offsetting payment was perhaps not high to justify the implementation of the scheme. It was however found that reconfiguring the energy systems would definitely be a worthwhile exercise. On corporate level where efficiencies of size amplify gains, Drifters, as a group of 14 lodges and an overland company, may well find that a transparent voluntary emissions reduction (VER) payment, ring-fenced, appropriately used, and properly implemented, is worthwhile. Ethically, however, injecting VER payments into a balance sheet is problematic, especially where the payback period of the technological interventions is short and the benefits derived are long term. / AFRIKAANSE OPSOMMING: Die gebruik van fossielbrandstowwe wat in die huidige tydsgewrig tot die opwekking van oormatige kweekhuisgasse lei is nie langer aanvaarbaar nie en innoverende opsies om die voortgesette generasie van energie te verseker, sal nagestreef moet word. Een van die grootste verbruikers van energie is vervoer, en vervolgens is dit ook die geval dat toerisme, wat swaar op vervoer staatmaak, ‘n groot gebruiker van energie is. Aangesien daar etlike gevestigde bome en bosse op hierdie woestynreservaat is, is die Drifters Desert Nature Reserve (DDNR) moontlik ‘n netto bespaarder van koolstofgasse, maar dit kan nie sondermeer daargelaat word in ‘n bedryf wat bekend is daarvoor dat dit graag die moeilike vrae vermy nie. Daar is dus gevra: is daar bekostigbare tegnieke wat moontlik by die DDBR aangewend kan word om die koolstofvoetafdruk te verminder en dit in staat kan stel om totaal koolstofneutraal te word, sonder om op ingryping staat te maak? Navorsing is gedoen en 121 vraelyste is voltooi om vas te stel of kliente gewillig sou wees om ‘n vrywillige bydrae te maak om die afskeid van koolstof te beheer en daardeur hul eie koolstofvoetafrdruk te verminder, in ‘n sg “gewilligheid om te betaal” oftewel “willingness to pay” (WTP) opname. Die resultate is deurgevoer as verteenwoordigend van die 1 055 kliente wat verlede jaar die oord besoek het. Daar is gevind dat 73% van die kliente wat die oord besoek bereid sou wees om die DDNR geldelik te help om sy stelsels te verander as ‘n teenrekening om hul eie koolstofbesoedeling op pad daarheen te vergoed. Kliente wat die losie gebruik het was bereid om meer te betaal as diegene wat by die kampeerterrein tuisgegaan het. Die hele reservaat se jaarlikse koolstofdioksied debiet is bereken, en die jaarlikse opwekking is op ongeveer 30-tonne vasgestel. Nes in Namibie as geheel is vervoeruitlaatgasse verantwoordelik vir die oorgrote meerderheid opwekking, met die voorsiening van energie by die afgelee oord kort op sy hakke. Van die vier moontlike ingrypings wat oorweeg is, is twee finansieel die moeite werd gevind, ongeag die kliente se gewilligheid om geldelik by te dra. Die bestuur van aanvraag is ook oorweeg, en hoewel dit nie gekwantifiseer is nie, is dit nes die moontlikheid van tegnologiese innovering, duidelik deel van die oplossing, Daar is gevind dat ‘n stelsel van betaling op plaaslike vlak moeilik sou wees om die administreer, en aangesien selfs die gewilliges nie oorgretig is nie, is daar tot die gevolgtrekking gekom dat dit nie die moeite sou loon nie. Ongeag bogenoemde beginsel van toersitebydraes is daar gevind dat dit ongetwyfeld die moeite werd sou wees om die energiestelsels aan te pas. Maar dit sal nie noodwendig op ‘n korporatiewe of ‘n makro-skaal werk nie, veral nie waar grote ‘n rol speel nie. As maatskappygroep mag Drifters vind dat met ‘n deursigtige, vrywillige uitlaatverminderingspaaiement, wat afgebaken, korrek aangewend en effektief bestuur word, die kool die sous werd sou wees.

Carbon finance and reforestation : a survey of African cases

Lagrange, Chantal V. M. 12 1900 (has links)
Thesis (MPhil (Sustainable Development and Management))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This thesis addresses the topic of carbon finance in the context of reforestation and avoided deforestation. The research is based on the Nhambita Reduced Emissions from Deforestation and Degradation (REDD) and Agro-forestry carbon offset project in North West Mozambique. The thesis raises important questions in terms of the relevance of carbon offset projects to human and biophysical realities in Africa. The research was conducted through the lens of ethnographic development and explores how carbon offset projects are received by recipient communities. What issues do such projects attempt to address? Are the targeted issues the „real‟ issues, as they are perceived by local populations in developing countries? Who do such projects benefit and who do they benefit the most? The thesis comprises two academic papers. The first paper is a synthesis article presenting a review of key issues with regards to the roll-out of improved cooking stoves (ICS) in the context of carbon offset projects, combined with a pre-feasibility study on the introduction of ICS in the Nhambita village. It shows how biomass will continue to play a dominant role in addressing Southern African energy needs and how a large scale dissemination of ICS could play a seminal role in alleviating pressure on threatened ecosystems. The paper, however, recognizes that ICS programmes are not a panacea and discusses the pitfalls of paradigms underlying stove-provision programmes to date. Based on a review of the pertinent literature and on the field work conducted in Mozambique, conclusions are drawn that environmental and health considerations do not constitute a sufficient „pull‟ factor from the end user‟s perspective. It appears that best channels to engage with the targeted users are economic and social rationales. This debate is of particular relevance to climate change policy but it also offers insights in terms of the acceptance of such programmes by the target communities. The second paper is related to the first in that it discusses the opportunities and challenges associated with the developmental ambitions of carbon offset projects. By virtue of the market systems that regulate them, such carbon offset projects imply an innovative developmental praxis, whereby project recipients become the owners and the sellers of a tangible good in the form of carbon credits. This innovative dimension is, however, thwarted by the fact that such projects stir welfare expectations from project participants. Such livelihood improvement expectations become the fertile ground for difficulties reminiscent of the weakness of traditional aid. The intricacies underpinning this new mechanism that combines land use changes with environmental conservation and livelihood benefits are debated in the context of private entrepreneurship and global markets. The analysis is anchored in a socioanthropological interpretation of climate change science and lays the emphasis on the risks and constraints of such projects, from the perspective of the target communities. The paper concludes by discussing the policy implications of these findings. / AFRIKAANSE OPSOMMING: Hierdie tesis behandel die onderwerp van koolstoffinansies binne die konteks van herbebossing en vermyde ontbossing. Die navorsing is gebaseer op die Nhambita Veminderde Emissies van Ontbossing en Degradasie (REDD) en die agrobosbou koolstofkompensasieprojek in Noord-Wes Mosambiek Die tesis opper belangrike vrae ingevolge die relevansie van koolstofverminderingsprojekte vir die menslike en biofisiese realiteite van Afrika. Watter kwessies probeer sulke projekte aanspreek? Is die geteikende kwessies die „ware‟ kwessies, soos hulle gesien word deur plaaslike bevolkings in ontwikkelende lande? Wie trek voordeel uit sulke projekte en wie trek die meeste voordeel daaruit? Die tesis behels twee akademiese verhandelings. Die eerste verhandeling is „n sinteseartikel wat „n oorsig bied van sleutelkwessies ten opsigte van die uitrol van verbeterde kookstowe (VKS) binne die konteks van koolstofverminderingsprojekte, gekombineer met „n vooruitvoerbaarheidstudie oor die bekendstelling van VKS in die Nhambita-dorpie. Dit dui aan hoe biomassa sal voortgaan om „n dominante rol te vervul in die aanspreek van energiebehoeftes in Afrika en hoe die onderliggende paradigmas van vorige stoofvoorsieningsprogramme heroorweeg moet word om tot die debat by te dra. Hierdie benadering erken die belangrikheid van hierdie hernubare energiebron, terwyl dit die ekologiese implikasies van die swaar steun op biomassa besef, veral in Suider Afrika. Gebaseer op 'n oorsig van gepaste literatuur sowel as die veldwerk gedoen in Mosambiek, word die gevolgtrekking gemaak dat omgewings- en gesondheidsoorwegings nie genoeg stukrag verleen vanuit die eindgebruiker se perspektief nie. Die beste kanale om by die teikengebruikers betrokke te raak, is ekonomiese en sosiale rasionale. Hierdie debat is van besondere betekenis vir die klimaatsveranderingsbeleid maar word ook fyn bestudeer ten opsigte van die aanvaarding van sodanige programme deur die teikengemeenskappe. Die tweede verhandeling is verwant aan die eerste in die opsig dat dit die geleenthede en uitdagings bespreek wat verband hou met die ontwikkelingsbehoeftes van koolstofverminderingsprojekte. Uit hoofde van die markstelsel wat hulle reguleer, impliseer sulke koolstofverminderingsprojekte „n innoverende ontwikkelingspraktyk, waarvolgens projekontvangers die verkopers word van „n tasbare voordeel in die vorm van koolstofkrediete. Hierdie innoverende dimensie word gedwarsboom deur „n tradisionele benadering tot ontwikkeling wat ontstaan uit die welvaartverwagtings van projekdeelnemers. Sodanige bestaansverbeteringverwagtings word die teelaarde van probleme kenmerkend van die swakheid van tradisionele bystand. Die ingewikkeldhede van hierdie nuwe meganisme, wat landgebruikveranderings kombineer met omgewingsbewaring, asook die bestaansvoordele word gedebatteer binne die konteks van privaat entrepreneurskap en wêreldmarkte. Die ontleding is geanker in „n sosio-antropologiese interpretasie van klimaatsveranderingwetenskap en benadruk die risiko‟s en beperkings van sulke projekte, vanuit die perspektief van die teikengemeenskappe.

Upsetting Offsets : A case study of Colombia and their legislation of biodiversity offsetting

Levin, Linda, Olsson, Linda January 2015 (has links)
Title: Upsetting Offsets - A case study of Colombia and their legislation of biodiversity offsetting Authors: Linda Levin and Linda Olsson Supervisor: Åsa-Karin Engstrand Background: The global loss of biodiversity is a very timely debate, and experts are actively working on finding new ways to lessen and reverse the negative impacts placed on the environment. One such way is biodiversity offsetting and it is a methodology that is becoming more prevalent within national environmental legislations. Colombia enforced a legislation regarding biodiversity offsetting in 2012, and it quickly became apparent that the process would not progress without its issues. Aim: The aim of this study is to research the government, NGOs and companies in relation to the legislation of biodiversity offsetting in Colombia established in 2012, to acquire knowledge regarding their roles, relationships and the challenges they are experiencing. Methodology: The empirical data was collected during a two months field study in Colombia. The data was collected in a qualitative manner, through interviews with employees at governmental entities, NGOs and companies. While conducting the empirical research, theoretical information was gathered, which implies an iterative approach. Conclusion: According to the results of this study, there are various issues to be found in the implementation process of the legislation, both in regards to practical difficulties, as well as in the relationships between the different actors. Some of these problems could be mitigated with a national habitat banking system, where the offsetting activities are managed by an external part.  Key words: Biodiversity offsetting, environmental governance, Colombia, NGOs, the government, companies, roles, relationships, challenges. / Bakgrund: Den globala negativa påverkan på den biologiska mångfalden är en högst aktuell debatt, och experter arbetar ständigt med att hitta nya sätt att vända de negativa effekterna på miljön. En metod som ämnar göra detta är ekologisk kompensering, vilken blir allt vanligare inom nationell miljölagstiftning. I Colombia trädde en lagstiftning gällande ekologisk kompensering i kraft under 2012, och det blev snart uppenbart att processen inte skulle fortskrida utan sina problem. Syfte: Syftet med denna studie är att i Colombia, undersöka regeringen, ideella organisationer och företag i relation till lagstiftningen om ekologisk kompensering som trädde i kraft 2012, för att förvärva oss kunskap om deras roller, relationer och utmaningar. Metod: Det empiriska datamaterialet samlades in under en två månader lång fältstudie i Colombia. Detta skedde kvalitativt, genom intervjuer med anställda på regeringsorgan, ideella organisationer och företag. Samtidigt som vi genomförde den empiriska undersökningen, samlade vi även in teoretisk information, vilket visar på användningen av en iterativ metod. Slutsats: Resultaten av denna studie visar att det finns vissa svårigheter i implementeringsprocessen av lagstiftningen, såväl gällande praktiska svårigheter, som i relationerna mellan de olika aktörerna. Några av dessa problem skulle kunna lösas med ett nationellt habitat banking system, där kompenseringsaktiviteterna hanteras av en extern part. Nyckelord: Ekologisk kompensering, miljöstyrning, Colombia, ideella organisationer, regeringen, företag, roller, förhållanden, utmaningar.
