In the tourism sector, hotel industry is one of the most important sub-sector. This hotel industry emits greenhouse gas (GHG) emissions mainly carbon dioxide (CO2) by consuming large amount of energy, water, and non-renewable resources in service operation everyday on basis. This paper presents results of analysis how much does the GHG emissions release in hotel. The Asian Institute of Technology Conference Center and Chiang Mai Hill 2000, Chiang Mai, Thailand have successfully estimated GHG emissions by using Bilan Carbone® tool. The mitigation options are to encourage low carbon dioxide hotels. The data collection was done by questionnaires, interviews, and observations in both of them hotels. The results of annual GHG emissions contributor both Chiang Mai Hill 2000 as 3,844 t CO2 and at AITCC about 1,011 t CO2. Energy use is a major emission contributor followed by travel, property, input material, waste generated, and freight. Higher number of guests/tourists flow, effected higher used of facilities such as electricity, air conditioning, lighting, and food & beverage. Larger size hotel service quality, greater guest room service, wide range of building area, greater facilities, and large functional are consumed higher energy and materials. As well as, the higher rate of room turning can also increase of emissions. Moreover, Chiang Mai Hill 2000 tends to take transportation which have longer distance than AITCC. Therefore, increasing higher journal distance generated higher GHG emissions as well. The short term and long term mitigation plans can also be taken into consideration to reduce GHG emissions. The recommendation of short term mitigation plans can be applied directly in both hotels thus, increasing awareness about climate change and energy conservation among uses. The long term mitigation plans recommends to give “Green Hotel” award to successful hotels for reducing GHG emissions in hotel. These plans can be incorporated the Thailand’s government policy to reduce the impacts of climate change to the hotel industry.

The Earth

The cycle of carbon is essential to the maintenance of life, to climate, and to the composition of the atmosphere and oceans. What is normally thought of as the “carbon cycle” is the transfer of carbon between the atmosphere, the oceans, and life. This is not the subject of interest of this book. To understand this apparently confusing statement, it is necessary to separate the carbon cycle into two cycles: the short-term cycle and the long-term cycle. The “carbon cycle,” as most people understand it, is represented in figure 1.1. Carbon dioxide is taken up via photosynthesis by green plants on the continents or phytoplankton in the ocean. On land carbon is transferred to soils by the dropping of leaves, root growth, and respiration, the death of plants, and the development of soil biota. Land herbivores eat the plants, and carnivores eat the herbivores. In the oceans the phytoplankton are eaten by zooplankton that are in turn eaten by larger and larger organisms. The plants, plankton, and animals respire CO2. Upon death the plants and animals are decomposed by microorganisms with the ultimate production of CO2. Carbon dioxide is exchanged between the oceans and atmosphere, and dissolved organic matter is carried in solution by rivers from soils to the sea. This all constitutes the shortterm carbon cycle. The word “short-term” is used because the characteristic times for transferring carbon between reservoirs range from days to tens of thousands of years. Because the earth is more than four billion years old, this is short on a geological time scale. As the short-term cycle proceeds, concentrations of the two principal atmospheric gases, CO2 and CH4, can change as a result of perturbations of the cycle. Because these two are both greenhouse gases—in other words, they adsorb outgoing infrared radiation from the earth surface—changes in their concentrations can involve global warming and cooling over centuries and many millennia. Such changes have accompanied global climate change over the Quaternary period (past 2 million years), although other factors, such as variations in the receipt of solar radiation due to changes in characteristics of the earth’s orbit, have also contributed to climate change.

Long Term Studies

Many nations have recognized the need to reduce the emissions of greenhouse gases (GHGs). The scientific assessments of climate change of the Intergovernmental Panel on Climate Change (IPCC) support the need to reduce GHG emissions. The 1997 Kyoto Protocol to the 1992 Convention on Climate Change (UNTS 30822) has now been signed by more than 65 countries, although that Protocol has not yet entered into force. Some 14 of the industrialized countries listed in the Protocol face reductions in carbon dioxide emissions of more than 10% compared to projected 1997 carbon dioxide emissions (Najam & Page 1998).

Cross Model

We investigate the long-term global energy technology diffusion patterns required to reach a stringent climate change target with a maximum average atmospheric temperature increase of 2°C. If the anthropogenic temperature increase is to be limited to 2°C, total CO 2 emissions have to be reduced massively, so as to reach substantial negative values during the second half of the century. Particularly power sector CO 2 emissions should become negative from around 2050 onwards according to most models used for this analysis in order to compensate for GHG emissions in other sectors where abatement is more costly. The annual additional capacity deployment intensity (expressed in GW/yr) for solar and wind energy until 2030 needs to be around that recently observed for coal-based power plants, and will have to be several times higher in the period 2030–2050. Relatively high agreement exists across models in terms of the aggregated low-carbon energy system cost requirements on the supply side until 2050, which amount to about 50 trillion US$.

Active travel (walking, cycling or scooting for transport) is considered a healthy and sustainable form of getting from A to B. The net effects of active travel on mobility-related carbon dioxide (CO2) emissions are complex and remarkably under-researched across a wide range of settings. This paper seeks to provide a summary of research on active travel as a low carbon mobility option in context of the climate emergency. Key gaps are identified and discussed. The paper concludes with a projection of future research.

Strategic Actions

Purpose The purpose of this paper is to address the perceptions of managers in large companies located in Brazil regarding the long-term and short-term benefits of adopting strategic actions to mitigate and adapt to climate change. Design/methodology/approach Based on an empirical analytical method, this paper examines interviews conducted with senior managers of leading companies located in Brazil to identify their perceptions of adopting strategic actions toward mitigating and adapting to climate change. Findings The key results are as follows: the most commonly perceived long-term benefit was operational improvement, based on the improved energy efficiency of operations; strategic management of aspects affected by climate change can make managers more aware of the benefits derived from the decisions taken; and a short-term view and aversion to uncertainty can lead to failures in strategic management, limiting the effectiveness of actions for mitigating and adapting to climate change. Originality/value This paper contributes to the literature on the topic of climate change by presenting evidence that adaptation and mitigation measures can increase organizational managers’ perception of long-term benefits, and that climate change management structures guide managers to make the transition to a low-carbon economy.

The Impact

<p>Agricultural soils are an important landscape element in terms of climate change and this ecosystem is considered as a one of the major source of greenhouse gases (GHGs). Soil may be also a sink for GHGs, from this reason so many research projects are focused on determination of factors and conditions affecting gas exchange. Biochar is produced from biomass that has been pyrolysed in a zero or low oxygen availability. It is currently widely considered as a stable addition to the soil, which not only improve its fertility, but also can mitigate climate change. Considering landscape elements, the char also prevents carbon loss from forest soils. Higher microbial activity is usually associated with higher carbon dioxide (CO<sub>2</sub>) production (soil respiration). One of the most important questions is how does biochar influence production of GHGs such as CO<sub>2</sub>? Which doses have a critical meaning for CO<sub>2</sub> emission? The aim of our study was to determine the effect of wide range doses of biochar (produced from sunflower husks) (from 1 to 100 Mg ha<sup>-1</sup>) to Haplic Luvisol soil from fallow fields. We investigated the changes of CO<sub>2</sub> emission during laboratory incubation using gas chromatography method. In short-term incubations soil respiration was positively correlated with increasing biochar dose, while during long-term (several years) observation, the impact of biochar dose on the amount of emitted CO<sub>2</sub> was not so significant. It is worthwhile to conduct short- term and long-term field studies in this area.</p><p>Research was partially conducted under the project “Water in soil - satellite monitoring and improving the retention using biochar” no.

Energy is the prominent navigator of climate change as it contributes to most of the greenhouse gases (GHGs) and the burning of fossil fuels are the foremost sources of GHG emissions. Climate change is a major challenge for developing countries like India that face large scale climate variability and are exposed to enhanced risks from climate change. Few countries in the world are as vulnerable to the effects of climate change as India is with its vast population that is dependent on the growth of its agrarian economy, its expansive coastal areas and the Himalayan region and islands. The vulnerabilities of climate change and energy insecurity are directing a global changeover towards a low carbon and sustainable energy path. In the UNFCC, India has cleared its stand that it would not make any commitments to trim down its GHG emissions as it has one of the least per capita emissions and in the fi rst place the developed world is responsible for the dilemma and the developing world requires the carbon space to spring up. But by being a responsible and progressive member of the international community, India demonstrated the flexibility towards the endeavours to trim down climate change causalities. India is endowed with diverse natural resources such as solar, wind, water and biomass; these are the promising resources to meet up the energy requirements of the coming years. The present paper attempts to analyse the linkages between climate change and energy security. The paper also aims to project India’s response to the global climate regime. The paper argues that the problems of climate change and energy security are the major obstacles for India’s energy policy while they open gargantuan opportunities to shift its people to cleaner energy trajectories and know-how in the long term.

Mass transfer from single carbon dioxide bubbles in a vertical pipe is measured using a stereoscopic image processing method to develop a mass transfer correlation applicable to a wide range of bubble and pipe diameters. The pipe diameters are 12.5, 18.2 and 25.0 mm and the bubble diameter ranges from 5 to 26 mm. The ratio, λ, of bubble diameter to pipe diameter is therefore varied from 0.2 to 1.8, which covers various bubble shapes such as spherical, oblate spheroidal, wobbling, cap, and Taylor bubbles. Measured Sherwood numbers, Sh, strongly depend on bubble shape, i.e., Sh of Taylor bubbles clearly differs from those of spheroidal and wobbling bubbles. Hence two Sherwood number correlations, which are functions of the Peclet number and the diameter ratio λ, are deduced from the experimental data: one is for small bubbles (λ < 0.6) and the other for Taylor bubbles (λ > 0.6). The applicability of the proposed correlations for the prediction of bubble dissolution process is examined through comparisons between measured and predicted long-term bubble dissolution processes. The predictions are carried out by taking into account the presence of all the gas components in the system of concern, i.e. nitrogen, oxygen and carbon dioxide. As a result, good agreements for the dissolution processes for various bubble sizes and pipe diameters are obtained. It is also demonstrated that it is possible to evaluate an equilibrium bubble diameter and instantaneous volume concentration of carbon dioxide in a bubble using a simple model based on a conservation of gas components.

Carbon Dioxide Equivalent

Breeding of rice varieties with low carbon dioxide equivalent (CO2e) emission is essential in reducing global greenhouse gas (GHG) emissions. In this study, we compared the gross CO2e emission of two newly developed green super rice (GSR) varieties with elite hybrids and nationally released farmer-cultivated varieties from production to post-production in the dry and wet seasons in Laguna, Philippines. The average gross CO2e emission was 17.9 tons CO2e ha-1 or 2.98 tons CO2e ton-1 rice (production 82%, post-production 18%). Contributing to this total were soil emissions at 72%, the use of chemicals at 5%, burning of rice straw at 3%, cooking at 12%, and transportation at 5%. The average social cost of carbon (SCC) per ton of rice was estimated at $119. Increasing grain yield per unit area with shorter growth duration decreased CO2e emission of rice per unit of weight. Cultivation of rice varieties GSR8 and GSR2 emitted 37.0% lower CO2e than the popular inbred varieties.

Term Storage

A grand challenge facing society is climate change caused mainly by rising CO2 concentration in Earth’s atmosphere. Terrestrial plants are linchpins in global carbon cycling, with a unique capability of capturing CO2 via photosynthesis and translocating captured carbon to stems, roots, and soils for long-term storage. However, many researchers postulate that existing land plants cannot meet the ambitious requirement for CO2 removal to mitigate climate change in the future due to low photosynthetic efficiency, limited carbon allocation for long-term storage, and low suitability for the bioeconomy. To address these limitations, there is an urgent need for genetic improvement of existing plants or construction of novel plant systems through biosystems design (or biodesign). Here, we summarize validated biological parts (e.g., protein-encoding genes and noncoding RNAs) for biological engineering of carbon dioxide removal (CDR) traits in terrestrial plants to accelerate land-based decarbonization in bioenergy plantations and agricultural settings and promote a vibrant bioeconomy. Specifically, we first summarize the framework of plant-based CDR (e.g., CO2 capture, translocation, storage, and conversion to value-added products). Then, we highlight some representative biological parts, with experimental evidence, in this framework. Finally, we discuss challenges and strategies for the identification and curation of biological parts for CDR engineering in plants.
