Uzbekistan's Carbon Footprint: Challenges and Prospects
Introduction
The carbon footprint is the total amount of greenhouse gas emissions caused by human activities, expressed in carbon dioxide equivalent (CO2 equivalent). These emissions include CO2, methane (CH4), nitrogen oxide (NO2) and other gases that contribute to global warming. Carbon footprints can be measured for individuals, organisations, products and even countries to assess their contribution to climate change.
Carbon footprint analysis is important for several reasons. First of all, it helps to identify the main sources of greenhouse gas emissions in the country, which allows the development of targeted measures to reduce them. In addition, a carbon footprint assessment allows the effectiveness of environmental policies and measures taken to reduce emissions to be monitored and necessary adjustments to be made. Understanding carbon footprints also helps countries mitigate the effects of global climate change, such as extreme weather, sea level rise and biodiversity loss.
The carbon footprint is the total amount of carbon dioxide and methane that is released into the environment as a result of human activity. By accumulating in the atmosphere, these gases increase the greenhouse effect, which leads to global warming and destabilisation of the planet's climate. The difficulty is that virtually every human activity produces carbon emissions in one way or another. Travelling to work by car, buying a washing machine, renovating a flat have their carbon footprint.
Evolution of the Earth's global temperature
Global climate change has always occurred on our planet and will continue to do so. However, it is a very difficult task to find time periods in the past where changes have occurred as rapidly as they are occurring now.
This "acceleration", according to the researchers, is provided by a combination of both natural factors and anthropogenic greenhouse gas emissions.
It is appropriate to recall the words of V.I. Vernadsky that mankind in the course of its development turns into a new powerful "geological force", transforming the face of the planet with its thought and labour. And so it has happened: we change the reflectivity of the planet's surface, drain swamps, cut down forests, change the gas composition of the atmosphere. As a result, our planet's climate is changing so rapidly that humanity risks not having time to adapt to the new conditions it is directly involved in shaping.
The carbon footprint of the planet.
Many countries, including Uzbekistan, participate in international climate agreements, such as the Paris Agreement, which require regular monitoring and reporting of greenhouse gas emissions. Reducing carbon footprints can lead to economic benefits such as reduced energy costs, job creation in renewable energy sectors and improved quality of life for the population.
The main objectives of this article include reviewing the carbon footprint of Uzbekistan, analysing the current situation with greenhouse gas emissions in the country based on available statistics and reports. It is also important to identify the key economic sectors that contribute most to Uzbekistan's carbon footprint, such as energy, industry and agriculture. The existing measures and strategies applied in Uzbekistan to reduce greenhouse gas emissions, including the development of renewable energy sources and energy efficiency, should be assessed. The paper will conclude with recommendations for further reduction of the carbon footprint based on the best international practices and specifics of Uzbekistan.
Sources of carbon footprint in Uzbekistan
The largest contribution to emissions is made by the "Energy" sector with 76.6 per cent and the "Agriculture" sector with 17.2 per cent. The "IPPU (Industrial Processes and Product Utilisation)" sector accounts for 4.7% and the "Waste" sector for 1.5%.
The transport sector also contributes significantly to Uzbekistan's carbon footprint. In recent years, there has been a significant growth in the car fleet, which leads to an increase in CO2 emissions from vehicles. The underdevelopment of public transport exacerbates the situation, as many citizens prefer to use personal cars instead of public transport, which leads to an increase in the number of vehicles on the roads and, consequently, to an increase in greenhouse gas emissions. Analysis of the dynamics of specific emissions from transport (Fig. 1) allows us to distinguish three periods: 1997-2005. - period of specific emissions reduction, 2006-2012, period of relative stability, and 2013-2017. - a period of relative stability and 2013-2017 a period of rapid growth of specific emissions. - period of rapid growth of specific emissions, which reached the level of 2000. The main reason for the growth of specific emissions is the moderate growth of freight transport (by only 1.8%) during 2013-2017, with emissions growing by almost 12%, as well as the explosive growth in the number of cars.
Dynamics of specific emissions in the transport sector
The energy sector is the main source of Uzbekistan's carbon footprint. This area is dominated by thermal power plants fuelled by coal, oil and natural gas. These power plants are significant sources of CO2 emissions, as the combustion of fossil fuels produces large amounts of carbon dioxide. The share of thermal power plants in total electricity generation remains high, which significantly increases the country's carbon footprint. However, among other sectors (Figure 2), the energy sector has made the most progress in reducing specific emissions: from 1.027 tonnes/kWh in 1990 to 0.952 tonnes/kWh in 2000 and to 0.51 tonnes/kWh in 2017, or a doubling in almost 30 years.
Dynamics specific emissions by sector "chemical industry", "production of construction materials", "energy, agriculture"
Industry in Uzbekistan, particularly metallurgy and the chemical industry, is also a major source of greenhouse gas emissions. These industries traditionally consume large amounts of energy and use technologies that result in significant emissions of CO2 and other greenhouse gases. The production of cement and steel, which are essential for construction, also contribute significantly to the country's carbon footprint. These processes are energy intensive and result in significant CO2 emissions.
Agriculture is the second largest source of carbon footprint in Uzbekistan. Land use and livestock production contribute to emissions of methane (CH4) and nitrogen oxide (NO2), which are potent greenhouse gases. Methane is emitted during fermentation in the stomachs of ruminants and from the decomposition of organic matter in anaerobic conditions such as rice paddies and landfills. Nitrous oxide is emitted during the use of nitrogen fertilisers and manure storage During 2000-2017, emissions increased 2.1-fold (from 14.1 to 29.3 million tonnes), meat production increased 2.7-fold and milk production increased 2.8-fold.
In cement production, there has been a moderate downward trend in specific emissions since 2000. While in 2000 the indicator was 0.451 tonnes of emissions per tonne of cement, by 2017 it decreased to 0.374 tonnes of emissions per tonne of cement or by 17%. The chemical sector (ammonia production) showed a moderate downward trend in specific emissions during 1990-2000, after which the rate was maintained until 2018. In 2011, the favourable trend of decreasing specific emissions in transport and agriculture was replaced by an unfavourable trend (growth of specific emissions). The reasons are the rapid growth of cattle population in the absence of proper processing of livestock waste, as well as the slowdown in railway freight turnover. This creates a risk of breaching the country's commitments to reduce emissions compared to 2010.
Current situation and statistics
Analysis of data on greenhouse gas emissions in Uzbekistan shows that the main contribution to the country's carbon footprint comes from the energy sector, industry and agriculture. According to the World Bank and other international organisations, a significant part of CO2 emissions is associated with the use of fossil fuels for electricity and heat generation. Thermal power plants fuelled by coal, oil and natural gas have a significant impact on greenhouse gas emissions. The transport sector, where the number of cars is growing every year, also contributes significantly to the increase in emissions.
The Republic of Uzbekistan has increased its commitment in the updated Nationally Determined Contribution (NDC) to reduce specific emissions per unit of GDP by 35% by 2030 from 2010 levels. Uzbekistan's Nationally Determined Contribution (NDC) recognises the important role of structural reforms for successful implementation of change and attaches great importance to energy efficiency and renewable energy measures from both economic and climate change mitigation perspectives, namely:
1. Modernisation of energy generating capacities through the introduction of efficient and low-carbon technologies;
2. Large-scale introduction of renewable energy sources (solar, wind and biogas technologies, small and micro-hydro power plants, etc.);
3. Widespread introduction of energy efficient technologies in energy-intensive industries, construction and buildings;
4. Elimination of natural gas leaks and avoidance of gas flaring in the oil and gas sector;
5. Reduction of losses in electricity transmission and distribution networks.
The dynamics of greenhouse gas emissions in recent years shows a stable growth, which is associated with the country's economic development, increased industrial production and growth of the vehicle fleet. However, despite this growth, there has been a noticeable trend towards stabilisation of emissions in recent years due to efforts aimed at improving energy efficiency and developing renewable energy sources. Nevertheless, the government is taking active steps to control and reduce these emissions by introducing programmes to modernise the energy infrastructure and switch to cleaner energy sources.
Improving energy efficiency in industry, transport and the household sector is important. This includes replacing outdated equipment with more energy efficient counterparts and incentivising the use of energy saving technologies. In recent years, new solar and wind power plants have been commissioned in Uzbekistan, which also contributes to reducing greenhouse gas emissions. For example, the first large-scale solar park was launched in 2020 and further expansion of renewable energy sources is planned.
Environmental legislation also plays an important role in reducing carbon footprints. The development and implementation of regulations aimed at reducing greenhouse gas emissions include setting emission standards for industrial enterprises and vehicles. Uzbekistan's active participation in international climate agreements, such as the Paris Agreement, and cooperation with international organisations on environmental protection and climate change, helps the country to access advanced technologies and financial support for environmental projects.
These efforts demonstrate Uzbekistan's endeavour to reduce its carbon footprint and contribute to global efforts to combat climate change. It is important to continue and strengthen these measures in order to achieve sustainable development and improve the quality of life of the population.
Strategies and measures to reduce carbon footprints
One of the key areas of carbon footprint reduction in Uzbekistan is the improvement of energy efficiency. In this context, modernisation of the energy infrastructure is an important measure. This includes replacing old and inefficient equipment with new, more efficient technologies. For example, replacing obsolete turbines at thermal power plants with modern analogues can significantly reduce CO2 emissions. Energy efficiency improvements should take place in all sectors of the economy, including industry, transport and housing. In industry, significant emission reductions can be achieved by introducing energy efficient technologies and optimising production processes. In the residential sector, an important step is to insulate buildings and install energy efficient heating and air conditioning systems.
The government plays a crucial role in increasing public investment and mobilising innovative financial instruments for the green transition. According to the Ministry of Finance of Uzbekistan, Uzbekistan has issued US$ 870 million in bonds in 2021 to finance measures to achieve the Sustainable Development Goals (SDGs), including: land restoration, green development, and green energy. According to the Ministry of Finance, Uzbekistan issued USD 870 million in bonds in 2021 to finance measures to achieve the Sustainable Development Goals (SDGs), including: land rehabilitation, green transport development and the launch of the Green Sukuk mechanism; and to finance energy efficiency projects and other innovations. However, according to the new development strategy for 2022-2030, the implementation of which requires significant additional funds, these measures are not sufficient for a green transition. International experience shows that countries need to be able to mobilise financial resources of 6% of gross domestic product (GDP) to achieve the goals of the Paris Agreement. It is important to attract both public and private investment, and to mitigate climate change risks for already planned investments.
The development of renewable energy sources also plays a key role in reducing the carbon footprint. Uzbekistan has significant potential for the development of solar energy due to its favourable climatic conditions. The construction of solar power plants can significantly reduce the country's dependence on fossil fuels. In addition to solar energy, the development of small hydropower and bioenergy is a promising area. Small hydropower plants can be built on rivers and other water resources of the country, which will make it possible to utilise local natural resources for power generation. Bioenergy, including the use of biomass for energy production, can also contribute to the reduction of greenhouse gas emissions.
In agriculture and land use, the introduction of sustainable agricultural practices and reforestation are important measures. Sustainable practices include optimising fertiliser use, organic farming practices and water management. These measures reduce emissions of methane and nitrous oxide, which are potent greenhouse gases. Reforestation and the creation of new forest areas play an important role in absorbing CO2 from the atmosphere. Planting trees and restoring degraded land increases the area of forests, which helps to mitigate climate change.
The development of public transport and urbanisation are also important areas for reducing carbon footprints. The development of public transport, including the construction of new metro lines, trams and bus routes, can significantly reduce the number of private cars on the road and thus CO2 emissions. Incentivising the use of electric transport, including electric buses and cars, is also an effective measure. The introduction of subsidies and tax incentives for owners of electric vehicles can encourage their wider adoption.
During the policy dialogues, ministries and state bodies of Republic of Uzbekistan presented their plans and intentions to promote the green agenda. Below are samples:
▪ The Ministry of Finance of the Republic of Uzbekistan aims to work on greening the state budget and public procurement practices, to develop a monitoring system for SDG financing and is interested in introducing a "green" taxonomy;
▪ The Ministry of Energy of the Republic of Uzbekistan will continue to introduce economic incentives for investments in clean energy and has already established an Energy Efficiency Department;
▪ The Ministry of Water Resources of the Republic of Uzbekistan will fully promote the introduction of water-saving technologies and modern pumping stations;
▪ The State Committee on Forestry of the Republic of Uzbekistan will continue to increase reforestation and afforestation to double the forested area by 2030. In recent years, 600 thousand hectares of forests have been planted, including 458 thousand hectares in the Priaralie zone;
▪ The private sector will build leadership in farming to address the impacts of climate change and recycling;
▪ The Ministry of Higher Education, Science and Innovation and the Ministry of Employment and Poverty Reduction of the Republic of Uzbekistan will develop green modules in the education system, offer new youth employment opportunities and innovative solutions, including digital technologies. The stakeholder mapping conducted by the researchers points to the need for greater involvement of local traditional structures, including the mahalla;
▪ The Agency of Hydrometeorological Service under the Ministry of Ecology, Environmental Protection and Climate Change of RUz is working on finalising a climate strategy and roadmap, and working on adaptation plans in key areas of the economy, from agriculture, water management and health to disaster risk reduction and urban environment.
These strategies and measures represent a comprehensive approach to reducing Uzbekistan's carbon footprint. Their implementation requires concerted efforts on the part of the government, business and society. Only through joint efforts can significant results be achieved in combating climate change and ensuring sustainable development of the country.
International co-operation and support
Uzbekistan's participation in international environmental agreements is an important component of efforts to reduce its carbon footprint and combat climate change. Uzbekistan is a party to the Paris Agreement, which obliges the country to develop and implement national strategies to reduce greenhouse gas emissions. Under this agreement, Uzbekistan regularly reports on its emissions and measures to reduce them, and commits to reducing its carbon footprint in line with global goals to limit the rise in global temperatures.
Projects and initiatives with international organisations play an important role in supporting Uzbekistan's efforts to reduce its carbon footprint. Organisations such as the World Bank, the United Nations Development Programme (UNDP), the Asian Development Bank (ADB) and others are actively cooperating with Uzbekistan by providing financial and technical support. For example, the World Bank finances projects to modernise energy infrastructure and develop renewable energy sources. The UNDP is implementing programmes to improve energy efficiency in various sectors of the economy, as well as projects on sustainable land use and reforestation. ADB supports transport infrastructure projects aimed at developing public transport and reducing emissions from road transport.
The project "Innovative Carbon Finance for Transforming Uzbekistan's Energy Sector" is the first project of its kind under the World Bank's programme supporting the implementation of government policies to reduce emissions in the energy sector. Thus, the $46,250,000 grant provided under the project will be used to stimulate energy subsidy reform measures. These will lead to a reduction in energy consumption and greenhouse gas emissions.
In particular, the project will allow Uzbekistan to accumulate so-called "carbon credits" (reduced greenhouse gas emissions measured in tonnes of CO2 equivalent) and sell them on international carbon markets. This project will be the first such international initiative in Uzbekistan and Central Asia under the Paris Agreement, which will give the country access to carbon market mechanisms. The goal of the above-mentioned international treaty is to limit global temperature rise by reducing the world's greenhouse gas emissions.
Globally, the greenhouse gas emissions generated by the country are not so large. However, Uzbekistan is among the countries with the highest level of energy intensity and, consequently, specific greenhouse gas emissions. This situation is explained by high subsidies for energy production and transmission. (https://www.vsemirnyjbank.org/ru/news/press-release/2023/06/30/innovative-world-bank-project-will-help-uzbekistan-reduce-emissions-and-access-international-carbon-markets).
International co-operation has a significant impact on reducing Uzbekistan's carbon footprint. Firstly, it allows the country to gain access to advanced technologies and best practices, which facilitates the effective implementation of measures to reduce greenhouse gas emissions. Secondly, international co-operation opens up opportunities for attracting the financial resources needed to implement major environmental projects and initiatives. Thirdly, participation in international agreements and projects helps Uzbekistan to integrate into the global community, share experience and knowledge with other countries, which contributes to the improvement of national policy in the field of environmental protection and climate change.
These efforts within the framework of international co-operation help Uzbekistan to achieve sustainable development and reduce its carbon footprint, contributing to global efforts to preserve the planet. It is important to continue to strengthen co-operation with international partners and to develop new projects and initiatives aimed at protecting the environment and combating climate change.
Summarising the analysis of Uzbekistan's carbon footprint shows that the main sources of greenhouse gas emissions in the country include the energy sector, industry and agriculture. Thermal power plants fuelled by coal, oil and natural gas, significant growth in the vehicle fleet and traditional agricultural practices contribute most to the country's carbon footprint. However, Uzbekistan is taking active steps to reduce these emissions, including modernising energy infrastructure, improving energy efficiency and developing renewable energy sources.
The importance of an integrated approach to addressing the carbon footprint is clear. Reducing greenhouse gas emissions requires concerted efforts in all sectors of the economy, from energy and industry to transport and agriculture. An integrated approach includes modernising equipment, introducing energy-efficient technologies, developing renewable energy sources and sustainable agricultural practices. An important part of this approach is international co-operation, which provides access to the advanced technologies and financial resources needed to implement environmental projects.
The prospects and expectations from the implementation of carbon footprint reduction measures in Uzbekistan are very encouraging. The development of solar energy, small hydropower and bioenergy, as well as energy efficiency improvements in various sectors of the economy, can significantly reduce greenhouse gas emissions. In addition, efforts to develop public transport and encourage the use of electric transport will help reduce CO2 emissions from road transport. The adoption of sustainable agricultural and reforestation practices is also expected to make a significant contribution to reducing carbon footprints.
Uzbekistan's contribution to global efforts to preserve the planet is an important part of the fight against climate change. The country actively participates in international climate agreements, such as the Paris Agreement, and cooperates with international organisations to implement environmental projects. These efforts not only contribute to reducing Uzbekistan's carbon footprint, but also help in achieving global goals to limit the rise in global temperatures. Uzbekistan has demonstrated its commitment to sustainable development and its readiness to contribute to global efforts to preserve the environment.
Thus, a comprehensive approach to reducing the carbon footprint, including modernisation of the energy infrastructure, development of renewable energy sources, energy efficiency and international cooperation, is the key to successfully addressing the problem. The implementation of these measures will allow Uzbekistan to significantly reduce greenhouse gas emissions and make a significant contribution to global efforts to combat climate change.
