The climate change is a global environmental problem. Its solution requires thereduction of greenhouse gas emissions, especially CO2, as soon as possible. The developmentand implementation of low-carbon technologies can help in achievement this goal. Disturbedlands, which are a source of environmental pollution, can be used to reduce CO2 emissions. Wepropose to introduce technologies for locating solar and wind power plants on disturbed lands,primarily on mining dumps of overburden. The capacity of such solar and wind power plants canreplace thermal power plants, which generate the main volumes of CO2 emissions. Placing onthe mining dumps of overburden of solar power plants has advantages due to the use of southernexposures of the slopes. The wind power plants on the top of mining dumps of overburden takemore opportunities to use of wind speed by attracting additional height. Mining dumps haveemitted carbon dioxide due to the decomposition of limestone and the spontaneous combustion ofcarbon-containing rocks. Counteraction of CO2 emissions by coating the surface with inert materialsthat block the access of moisture and acid solutions to hazardous rocks is proposed. The useof new technologies for the rehabilitation of disturbed lands through the formation of secondaryecosystems creates opportunities to reduce greenhouse gas emissions. This have avoids additionalCO2 emissions during the operation of machines and mechanisms at the mining–technicaland biological stages of reclamation. Secondary soils able to accumulate carbon in the form oforganic matter up to 11 t / ha for 30–50 years. The study of technogenic soils formation on loess-like loams in the landscape reserves “Vizyrka” (Inguletsky GOK), “Hrushivka” (MarganetskyGOK), “Vershina” (Prosyansky GOK) are have evidenced of this facts. Plant components of ecosystemshave even more opportunities. Secondary vegetation absorbs CO2 from the atmosphereduring photosynthesis, creates the coating of surface of lands disturbed by mining operations.Clover plant group show the greatest ability to accumulate carbon (up to 57 t/ha per year). Theresearch was carried out at the research area of Inguletsky GOK. Our assessment testifies that theintegrated application of the above technologies will reduce emissions in Kryvbas by 95 milliontons of CO2 per year. The work was carried out under the target program of the National Academyof Sciences of Ukraine “Scientific and technical and economic and ecological foundations oflow-carbon development of Ukraine”.

The production of primary aluminum is an energy-intensive industry which produces large amounts of direct and indirect greenhouse gas emissions, especially from electricity consumption. Carbon Emissions Constrained Energy Planning proved to be an efficient tool for reducing energy-related greenhouse gas emissions. This study focuses on energy planning constrained by CO2 emissions and determines the required amount of CO2 emissions from electricity sources in order to meet specified CO2 emission benchmark. The study is demonstrated on and applied to specific aluminum products, aluminum slugs and aluminum evaporator panels. Three different approaches of energy planning are considered: (i) an insight-based, graphical targeting approach, (ii) an algebraic targeting approach of cascade analysis, and (iii) an optimization-based approach, using a transportation model. The results of the three approaches show that approximately 2.15 MWh of fossil energy source should be replaced with a zero-carbon or 2.22 MWh with a low-carbon energy source to satisfy the benchmark of CO2 emissions to produce 1 t of aluminum slug; however, this substitution results in higher costs. This study is the first of its kind demonstrated on and applied to specific aluminum products, and represents a step forward in the development of more sustainable practices in this field.

The article discusses the key risks of implementing a strategy for long-term socio-economic development of Russia with a low level of greenhouse gas emissions. In recent years, the climate agenda has been the most important driver of structural shifts in the world economy and is viewed by leading countries as a factor in intensifying economic growth and consolidating their technological leadership at the global level. In this context, Russia’s efforts to reduce its carbon footprint without direct import of low-carbon technologies and equipment from developed countries will run into non-recognition (of the carbon sink by Russian forests and carbon-free nature of nuclear and large hydro power plants) and increase in requirements for even more radical reduction in emissions. At the same time, Russia is already making a significant contribution to achieving the goals of the Paris Agreement. The article provides a list of measures that should underlie a balanced national climate policy. The strategy for the socio-economic development of Russia with a low level of greenhouse gas emissions should provide for a balance between solving the problems of preserving the population, improving the quality of its life, and ensuring dynamic and inclusive economic growth in the country. Russia’s potential announcement of commitments to unequivocally achieve carbon neutrality by mid-century carries serious risks to national interests. Instead, a more flexible language should be used to strive for carbon neutrality.

Performance Evaluation System

Nowadays, global warming is a big challenge for human beings; since the Kyoto Protocol became effective, greenhouse gas emissions have been an important environmental evaluation index in all industries. Construction is a big contributor to greenhouse gas emissions. The greenhouse gas emissions in the construction stage are mainly from the construction materials and the construction activities. The purpose of this paper is to quantitatively calculate the carbon dioxide emissions in the construction process, and provide a method of controlling the CO2 emissions effectively by converting into cost. In this study, the authors selected the tunnel construction as the research object, and chose the primary greenhouse gas-CO2 to estimate emissions. The authors did a research based on BIM (Building Information Modeling) technology, to calculate CO2 emission during the construction process. It considered the CO2 emissions from main materials and equipment. Finally, the authors used the recent carbon emission trading price to convert the CO2 emission into cost, and did the economic analysis. The method proposed in this paper can effectively evaluate the CO2 emissions in the construction process; it has a good reference significance for the selection of low-carbon emission materials in the design process, and it provides a case reference and direction for research of low-carbon equipment. By using the EU emissions trading system, the economic conversion of CO2 emissions will provide an economic evaluation index for the CO2 emissions of tunnel construction activities. Meanwhile, based on the method of this study, a BIM-based automated performance evaluation system could be developed.

AbstractClimate change risk will likely force the de-carbonization of our electricity sector and thus involve massive investments in long-lived assets using many new and emerging technologies. Since technological progress (independent or dependent on deployment) will likely lower the future cost of those technologies, investing early and rapidly forecloses saving money by installing those technologies at a lower cost later. There are thus benefits to waiting until the costs of renewables fall further. However, there are also costs to waiting. First, given the longevity of greenhouse gases in the atmosphere, cumulative emissions matter and lowering greenhouse gas emissions earlier is beneficial. Second, there is significant uncertainty not only over the rate of change of the cost of low carbon technologies, but also over the cost of greenhouse gas emissions. The costs of waiting are complex in that the distributions themselves are unknown (and quite possibly have “fat” tails). There may also be complex timing issues such as points of no return in terms of global greenhouse gas concentrations, beyond which the costs of adapting to climate change effects become essentially infinite. Hurrying can therefore be considered an insurance policy against the unknown but perhaps increasing risk of catastrophic damage.

Scenario Approach

On the eve of the worldwide negotiations of a new climate agreement in December 2009 in Copenhagen it is important to clearly understand what Russia can do to mitigate energy-related greenhouse gas emissions in the medium (until 2020) and in the long term (until 2050). The paper investigates this issue using modeling tools and scenario approach. It concludes that transition to the "Low-Carbon Russia" scenarios must be accomplished in 2020—2030 or sooner, not only to mitigate emissions, but to block potential energy shortages and its costliness which can hinder economic growth.

The Brazilian Amazon frontier shows how remarkable leadership can work towards increased agricultural productivity and environmental sustainability without new greenhouse gas emissions. This is due to initiatives among various stakeholders, including national and state government and agents, farmers, consumers, funding agencies and non-governmental organizations. Change has come both from bottom-up and top-down actions of these stakeholders, providing leadership, financing and monitoring to foster environmental sustainability and agricultural growth. Goals to reduce greenhouse gas emissions from land-cover and land-use change in Brazil are being achieved through a multi-tiered approach that includes policies to reduce deforestation and initiatives for forest restoration, as well as increased and diversified agricultural production, intensified ranching and innovations in agricultural management. Here, we address opportunities for the Brazilian Amazon in working towards low-carbon rural development and environmentally sustainable landscapes.

The Cost

The strategy of low-carbon development of the economy and energy of Russia provides for the introduction of a fee (tax) for carbon dioxide emissions by power plants. This will seriously affect their prospective structure and lead to an increase in electricity prices. The expected neg-ative consequences for national and energy security are great. But serious and multilateral research is needed to properly assess these strategic threats
