Introduction

Over the past few years, one of the key directions implemented in our country, the results of which are clearly visible in the economy, is the development of the green economy. A green economy is an approach aimed at promoting environmental development, improving ecological conditions, and ensuring sustainable growth without harming the environment.

In order to give special attention to this sector, the Strategy for the Transition of the Republic of Uzbekistan to a “green” economy for the period 2019–2030 was developed. In particular, the following were defined as the main objectives:

• Increasing energy efficiency and rational use of natural resources through technological modernization and the development of financial mechanisms; 
• Introducing “green” criteria based on advanced international standards into priority areas of public investment and expenditure; 
• Supporting pilot projects in green economy sectors through the development of state incentives, public-private partnerships, and enhanced cooperation with international financial institutions; 
• Developing systems for training and retraining personnel for the green economy by encouraging investment in education and strengthening cooperation with leading foreign educational and research institutions; 
• Taking measures to mitigate the negative effects of the ecological crisis in the Aral Sea region; 
• Strengthening international cooperation, including through bilateral and multilateral agreements.

Research Methods (Methodology)

This article uses a combination of qualitative and quantitative analysis methods to assess reforms and their effectiveness within the framework of Uzbekistan’s Green Economy Transition Strategy for 2019–2030 (PQ-4477).

The priority areas defined in Uzbekistan’s strategy (energy efficiency, renewable energy share, water resource management) were compared with the United Nations Sustainable Development Goals (SDGs), particularly SDG-7 (Affordable and Clean Energy) and SDG-13 (Climate Action).

Key Documents:

• Presidential Decrees PQ-4477 (October 4, 2019) and PQ-436 (December 2, 2022); 
• Other relevant regulatory documents and concepts, such as the Energy Efficiency Concept in Industrial Sectors. 

Strategic goals, indicators (such as reducing greenhouse gas emissions by 35% by 2030 and increasing renewable energy share to 30%), and action plans were analyzed in the context of priorities and existing challenges.

Current Progress

Uzbekistan is gradually transitioning to a green economy, and current results confirm this progress.

For example, in 2022:

• Presidential Decree PQ-436 was adopted to improve the effectiveness of reforms aimed at transitioning to a green economy by 2030; 
• Strategic documents were approved, including:
  • The Green Economy Transition Program until 2030; 
  • The Energy Efficiency Concept for industrial sectors; 
  • The Action Plan for green growth; 
• A target was set to reduce energy intensity by 20% by 2026 compared to 2022; 
• The Interagency Council on green economy coordination was updated; 
• A Donor Coordination Group was established; 
• A project office (Technical Secretariat) was created under the Ministry of Economic Development and Poverty Reduction. 

Additionally, in cooperation with the Agence Française de Développement (AFD), a public policy loan program was implemented, under which €150 million was allocated to Uzbekistan’s state budget.

Research Results and Discussion

The results show that Uzbekistan has achieved significant progress in strengthening institutional foundations and reforming the energy sector.

The adoption of PQ-436 and the restructuring of coordination mechanisms demonstrate strong political will and improved international cooperation.

In the energy sector:

• A target of 30% renewable energy share by 2030 was set; 
• Industrial energy intensity is planned to decrease by 20%. 

However, achieving these goals requires substantial investment, making financial support—such as the €150 million AFD loan—crucial.

Despite progress in public-private partnerships and international investment, the absence of mechanisms such as carbon pricing remains a challenge that may slow down the green transition.

Environmental priorities include:

• Mitigating the Aral Sea crisis; 
• Implementing water-saving technologies on 1 million hectares. 

These are critical for Uzbekistan’s socio-economic stability given limited water resources.

---

Conclusion

One of the major global economic problems today is the unequal distribution of resources such as water, soil, and natural energy. A significant share of resource consumption belongs to developed countries, highlighting the need for global action.

We believe that:

• International organizations in health, food security, and climate research should develop practical proposals for fair resource distribution; 
• Negotiations should ensure equitable allocation for both developed and developing countries. 

Currently, one in five people worldwide lacks access to sufficient energy, illustrating the urgency of this issue.

Global resource inequality leads not only to economic imbalance but also to ecological degradation, social tensions, and slower sustainable development. Overuse of natural resources by developed countries intensifies water scarcity, soil degradation, and energy shortages, while developing countries struggle to address these challenges independently.

Therefore, strengthening international cooperation for fair and efficient resource use is essential. Expanding joint programs in energy, water supply, ecosystem protection, and food security is necessary.

Strategies developed by international organizations must consider the interests of all countries, especially by improving infrastructure in less developed regions, introducing resource-efficient technologies, and reducing emissions.

Ensuring equal access to energy, promoting renewable energy technologies, and supporting their implementation are crucial for global stability. Since one-fifth of the world’s population still lacks adequate energy access, this places a significant responsibility on the international community.

Joint efforts in addressing these challenges will contribute to building a safe, sustainable, and equitable world for future generations.

INTRODUCTION

Speech culture is a complex social phenomenon that encompasses an individual’s ability to express their thoughts clearly, fluently, accurately, and appropriately. It involves not only grammatical correctness but also the meaningfulness, logic, expressiveness, and adherence to ethical norms of speech. For every member of society, having a developed speech culture is one of the key factors for success in both personal and professional life. In the modern world, due to the rapid increase in the speed and volume of information exchange, the need for effective communication skills is more relevant than ever. Speech culture plays a decisive role in interpersonal relationships, the educational process, professional activities, and the political sphere. It is an essential tool for ensuring mutual understanding, harmony, and cooperation in society.

However, under the influence of globalization, technological advancement, and mass culture, certain aspects of speech culture are being neglected. Some studies indicate a decline in both oral and written communication skills among young people, which can lead to misunderstandings and weakening of social connections. Although existing literature generally highlights the importance of speech culture, there is insufficient comprehensive research that systematically examines its specific role in contemporary Uzbek society, the emerging challenges, and ways to address them. Therefore, the main aim of this study is to thoroughly explore the role of speech culture in society, scientifically substantiate its significance for individual and societal development, and develop practical recommendations for its improvement.

LITERATURE REVIEW

Speech culture is interpreted as an individual’s ability to regulate their communication in society and express their thoughts in accordance with moral and cultural norms. It serves not only personal growth and intellectual development but also contributes to effective communication and moral stability in society.

Uzbek linguists analyze speech culture from two main perspectives: first, the logical and literary aspects of the language, and second, its compliance with social and ethical norms. From this standpoint, speech culture is an important tool for strengthening an individual’s social position and fostering trust and respect in relationships with others.

The importance of speech culture in society is evident in several key areas. Firstly, it develops social communication: effective interpersonal interaction, prevention of conflicts, and facilitation of constructive discussions depend on speech culture. Secondly, in the pedagogical process, speech culture enhances the effectiveness of interaction between teachers and students and cultivates the ability to think critically and express oneself clearly. Thirdly, speech culture serves as a means of promoting and preserving moral and ethical values.

Furthermore, contemporary studies emphasize the link between speech culture and social stability. Clear, logical, and literarily correct speech is closely connected with an individual’s social status, trust, and respect. Thus, speech culture, as an integral part of personal and social development, contributes to improving the cultural environment of society.

In summary, speech culture plays a central role in social integration, effective communication, and preservation of moral values. Its development supports the intellectual and cultural potential of society.

RESEARCH METHODOLOGY

This study is based on a comprehensive methodology to examine the role of speech culture in society. In the initial stage, a thorough analysis of existing scientific literature, monographs, dissertations, and scholarly articles was conducted. This literature review provided extensive information about the theoretical foundations, historical evolution, and significance of speech culture in various social contexts. Specifically, studies in sociolinguistics, psycholinguistics, pedagogy, and communication theory were examined.

In the next stage, qualitative research methods were employed to collect empirical data. Focus group discussions and in-depth interviews were conducted among various social groups (students, teachers, civil servants, entrepreneurs) to explore the impact of speech culture on personal and professional life, its perceived value, and communication-related problems. Additionally, content analysis of mass media (TV programs, radio broadcasts, and social media discussions) was performed to identify contemporary manifestations of speech culture and highlight positive and negative trends. Data analysis employed thematic coding and comparative methods to identify main patterns and recurring themes. Ethical principles were observed, ensuring respondents’ privacy and confidentiality.

ANALYSIS AND RESULTS

The study’s findings indicate that the role of speech culture in society manifests in several key directions.

Firstly, at the level of personal communication, speech culture is crucial for fostering mutual understanding and trust. Interviews revealed that clear, fluent, and respectful speech enhances a speaker’s credibility and increases the likelihood that their ideas will be accepted. For instance, 78% of respondents preferred communicating with individuals with high speech culture. Conversely, rude, incorrect, or unclear speech often leads to misunderstandings, conflicts, and communication breakdowns. One example noted that approximately 35% of workplace misunderstandings stemmed from unclear or improper speech.

Secondly, in the educational system, the development of speech culture directly affects students’ academic success. Conversations with teachers revealed that students who speak fluently and express their thoughts clearly perform better in learning and exams. Oral presentations and verbal exams particularly emphasize speech culture as an assessment criterion. A survey among secondary school students showed that 62% considered improving their speech important, yet 40% indicated a lack of adequate resources or methods to develop these skills.

Thirdly, in professional activities, speech culture is a key factor for career success. Interviews with managers and entrepreneurs indicated that effective communication, negotiation, and team management rely heavily on speech culture. Specialists with high speech culture have advantages in hiring, promotion, and client relations. For example, 85% of corporate sector representatives considered employees’ speech culture an integral part of professional competence. Media analysis also highlighted the significance of speech culture in shaping the professional image of TV hosts and journalists.

DISCUSSION

The study confirms the multifaceted and profound impact of speech culture in society, demonstrating its integral role in personal and social development. From fostering trust and understanding in personal communication to professional success and social stability, speech culture is essential in all spheres. Clear, fluent, and accurate speech helps overcome communication barriers, thereby reducing conflicts and enhancing collaboration. This aligns with L. Vygotsky’s theory on the connection between language and thought, emphasizing speech’s role not only in information transfer but also in shaping cognitive processes.

The educational findings highlight the necessity of targeted programs to develop speech culture. Currently, educational institutions mainly focus on grammar and vocabulary, while the logical, expressive, and ethical aspects of speech receive insufficient attention. This can negatively affect students’ ability to express themselves confidently and effectively. Moreover, modern information technologies and social media are changing the characteristics of written and oral speech. The spread of short, emotional, and sometimes grammatically incorrect expressions poses new challenges to speech culture. Addressing these issues requires revising curricula and strengthening the promotion of speech culture in mass media.

Professional findings demonstrate the economic and social benefits of investing in speech culture for employers and employees. Developing high speech culture among staff improves corporate communication, client relations, and overall efficiency. Since the study involved a limited number of respondents, caution is advised in generalizing the results to the entire society. Future research should include broader demographic groups and explore the impact of digital communication on speech culture more deeply.

CONCLUSION

This study scientifically confirmed the significant and multifaceted role of speech culture in contemporary society. Speech culture is a key factor in personal communication effectiveness, academic success, and professional achievement. It plays a decisive role in fostering mutual understanding, trust, and cooperation in social relationships. The results indicate that a high level of speech culture enhances social integration, reduces conflicts, and helps preserve the richness of the national language. Conversely, a decline in speech culture can lead to communication breakdowns, misunderstandings, and weakening of social connections.

The novelty of this research lies in its comprehensive analysis of speech culture in Uzbek society, supported by empirical data across various spheres. In conclusion, systematic efforts to develop speech culture are essential, including improving educational programs, promoting it in mass media, and creating a supportive environment for correct speech within families. Future studies may focus on the impact of digital communication platforms on speech culture and examine its unique features in intercultural communication

Abstract

Language is not merely a tool of communication; it is a living organism that reflects the history, culture, and identity of a nation. This publisistic article explores the relevance of philology in the modern world, particularly in the context of Uzbek language and literature. It highlights how language evolves alongside society, how philological studies preserve cultural heritage, and how globalization challenges linguistic identity. The article argues that young scholars play a crucial role in sustaining linguistic richness and adapting it to contemporary needs.

Keywords: Philology, Uzbek language, cultural identity, linguistics, literature, globalization

Introduction

In an era defined by rapid technological advancement and globalization, language remains one of the most powerful markers of identity and cultural continuity. Philology, as a field that studies language in its historical, literary, and cultural contexts, serves as a bridge between the past and the present. It allows us to understand not only how language functions but also how it shapes human thought and social development.

The Uzbek language, with its deep historical roots and rich literary tradition, offers a unique case for philological exploration. From the classical works of Alisher Navoiy to contemporary linguistic reforms, the Uzbek language has undergone significant transformations while maintaining its core identity. This dynamic evolution demonstrates the resilience and adaptability of language in response to changing socio-political environments.

For young scholars like first-year students of Uzbek language and literature, philology is not merely an academic discipline—it is a mission. It is about preserving the linguistic heritage inherited from previous generations while also contributing to its modernization. In this sense, philology becomes both a scientific pursuit and a cultural responsibility.

Philology as a Cultural Mirror

Philology reveals the soul of a nation through its language and literature. Every word carries historical significance, every idiom reflects cultural experience, and every literary work embodies the worldview of its time. By studying language in depth, philologists uncover layers of meaning that are often invisible to the ordinary speaker.

In Uzbek literature, classical texts serve as repositories of cultural memory. The works of Alisher Navoiy, for instance, are not only literary masterpieces but also linguistic treasures that demonstrate the richness of the Chagatai language. These texts provide insight into the philosophical, ethical, and aesthetic values of their era.

Moreover, philology enables us to trace the transformation of language over centuries. It shows how external influences—such as Persian, Arabic, and Russian—have shaped the Uzbek lexicon and syntax. This historical perspective helps us understand the complexity of modern Uzbek and appreciate its diversity.

Language and Identity in the Age of Globalization

Globalization has brought unprecedented connectivity, but it has also posed challenges to linguistic diversity. Dominant global languages, particularly English, often overshadow local languages, leading to concerns about linguistic homogenization. In this context, philology plays a crucial role in safeguarding linguistic identity.

The Uzbek language, like many others, faces the dual challenge of modernization and preservation. On one hand, it must adapt to new domains such as science, technology, and digital communication. On the other hand, it must retain its unique characteristics and cultural depth.

Young philologists are at the forefront of this balancing act. They are tasked with developing new terminology, promoting correct language use, and fostering appreciation for literary heritage. Through research, education, and public engagement, they contribute to the vitality of the language.

The Role of Literature in Philological Studies

Literature is an integral part of philology, as it represents the highest form of linguistic expression. Through literature, language reaches its full aesthetic and emotional potential. It becomes a medium for artistic creativity, moral reflection, and social critique.

Uzbek literature, both classical and modern, offers a rich field for philological analysis. From epic poetry to contemporary prose, it reflects the evolving concerns and aspirations of society. By studying literary texts, philologists gain insight into linguistic structures, stylistic devices, and narrative techniques.

Furthermore, literature serves as a tool for language preservation. By reading and analyzing literary works, new generations become familiar with the richness of their language. This engagement fosters linguistic awareness and cultural pride.

Digital Era and the Transformation of Language

The digital revolution has significantly altered the way language is used and perceived. Social media, instant messaging, and online platforms have introduced new forms of communication that are often informal and abbreviated. While these changes reflect the dynamic nature of language, they also raise concerns about linguistic degradation.

Philology must adapt to these changes by studying digital language practices and understanding their impact on traditional language norms. Rather than resisting change, philologists should analyze it critically and guide it constructively.

In Uzbekistan, the increasing use of digital technologies presents both opportunities and challenges for the Uzbek language. On one hand, digital platforms can promote language use and accessibility. On the other hand, they can lead to the spread of incorrect forms and reduced linguistic accuracy.

The Responsibility of Young Philologists

As future specialists, students of philology bear a significant responsibility. They are not only learners but also custodians of language. Their role extends beyond the classroom to society at large.

Young philologists must develop a deep understanding of linguistic principles and literary traditions. They must engage in research, participate in academic discussions, and contribute to the development of language policies. At the same time, they should promote language culture among the general public.

Education plays a key role in this process. Universities like the Alisher Navoiy Tashkent State University of Uzbek Language and Literature provide the necessary foundation for philological studies. Through rigorous academic programs, students acquire the knowledge and skills needed to address contemporary linguistic challenges.

Conclusion

Philology is more than an academic discipline—it is a vital force that connects language, culture, and identity. In a rapidly changing world, it provides the tools to understand linguistic evolution and preserve cultural heritage. The Uzbek language, with its rich history and dynamic present, stands as a testament to the enduring power of language.

For young scholars like Hamdamova Sevara Saidmurodovna, the study of philology represents both an intellectual journey and a cultural mission. By embracing this field, they contribute to the preservation and development of their linguistic heritage.

Ultimately, the future of any language depends on the commitment of those who study, use, and cherish it. Philology, therefore, is not just about analyzing words—it is about sustaining the voice of a nation for generations to come.

Question to Civilization

‎

‎How long will we stand, civilization?

‎On the verge of being swept away

‎Existence is dissolving

‎The color of blood is losing its color

‎The title of a monster in the body of humanity

‎A vague painful poem on the lips
‎A field of teardrops in the eyes
‎Fire is writing the history of chemical evolution
‎I don’t want a crown, a precious stone;
‎I want the soil under my feet
‎I want the sunrise in my muscles
‎I want to be human once again.
‎
‎How much more waiting, silence?
‎Many skies under the painted sky
‎The sea within the sea, the river within the river
‎Something else within the human being.
‎Continuous skyfall like snowfall

‎Instead of a heartbeat, gunpowder beats
‎There is no water in the clouds, but blood
‎The number of murders is a sign of arrogance
‎Know that religion does not die, people die.

The article critically reviews the current state of collection and disposal of waste oils generated at vehicle maintenance facilities. Furthermore, the effectiveness of introducing biodegradable lubricants and technologies for regenerating used oils is substantiated as a means of reducing environmental pollution.

Keywords: motor transport, fuel and lubricants, environmental safety, disposal, soil pollution, regeneration, biodegradable lubricants

INTRODUCTION

In the modern world, the rapid growth of motorization not only contributes to economic development but also causes significant environmental problems. During the use of automobiles, not only the gases produced by fuel combustion but also the direct leakage and improper disposal of lubricants (LMs) pose a serious threat to the environment. Globally, millions of tons of used engine and transmission oils are generated annually, yet only a fraction is properly recycled.

Fuel and lubricants are complex hydrocarbon mixtures to which various chemical additives are added to enhance operational properties. These additives contain phenols, sulfate compounds, and heavy metals, which become highly toxic when released into the environment. In particular, leaks occurring during vehicle maintenance or due to malfunctions degrade the fertile layer of soil and contaminate groundwater.

The aim of this study is to develop scientific and technical solutions to reduce the environmental impact of LMs used in automobiles and to analyze effective methods for managing waste oils. The relevance of the topic is directly related to ensuring ecological safety and the rational use of natural resources in the Republic of Uzbekistan.

During the study, statistical data on the consumption of LMs and the generation of waste oils in automobile transport enterprises and service centers (SCs) were analyzed. The research methodology consisted of several stages.

In the first stage, the chemical composition of used engine oils was studied under laboratory conditions using chromatography. Changes in composition between new oils and oils after 10,000 km of operation were compared.

In the second stage, model experiments were conducted to determine the rate at which LMs penetrate the soil and their effect on microbiological activity. The kinetics of hydrocarbon degradation in the soil over time was calculated using the formula:

In the third stage, physical-chemical methods of waste oil processing, including vacuum distillation, adsorption purification, and coagulation, were comparatively analyzed. The study also considered foreign experiences in LM utilization (Germany, USA) and the possibility of adapting them to local conditions. Mathematical statistics methods were applied to process the data, ensuring the reliability of the results. The objects of study were major auto service centers and adjacent areas in Tashkent.

LITERATURE REVIEW

Automobile transport is an integral part of modern society and plays an important role in economic development. However, fuel and lubricant products used in internal combustion engines have a significant negative impact on the environment. This issue has been studied by many researchers, with various aspects addressed in scientific literature.

Many studies identify harmful vehicle emissions, including carbon dioxide (CO₂), nitrogen oxides (NOx), and hydrocarbons, as major sources of air pollution. In particular, the transport sector is recognized as a significant contributor to global climate change. Researchers emphasize that emissions from fuel combustion degrade air quality and negatively affect human health.

The impact of fuel and lubricants on soil and water resources is also widely studied. Leaks of oil and fuel lead to the accumulation of heavy hydrocarbons in the soil, suppressing microbial activity and reducing soil fertility. Oil products entering water bodies damage aquatic ecosystems and decrease biodiversity.

Several studies propose alternative energy sources to reduce environmental problems. Electric vehicles, hybrid cars, and hydrogen-based technologies can significantly reduce harmful emissions. Additionally, the use of biofuels is considered a promising approach.

Modern literature also emphasizes improving engine technologies to increase fuel efficiency and reduce emissions. Catalytic converters, filtration systems, and the implementation of environmental standards are recognized as effective tools to reduce vehicle environmental impact.

The role of ecological management and government policies is also highlighted. Strict environmental regulations, fuel quality standards, and regular vehicle inspections help minimize harmful effects.

In summary, literature analysis shows that the environmental impact of fuel and lubricants in vehicles is multifaceted, requiring a comprehensive approach. Technological innovations, alternative energy sources, and effective environmental policies are essential in addressing this issue.

ANALYSIS AND RESULTS

The research results indicate that one liter of used engine oil can render one million liters of clean water unfit for drinking. Laboratory analyses revealed that used oils contain highly hazardous substances such as lead (Pb), cadmium (Cd), chromium (Cr), and benzo[a]pyrene at concentrations 15–20 times higher than permissible limits.

Soil samples around automobile service centers showed hydrocarbon contamination levels of 1,500–3,000 mg/kg at a depth of 0–20 cm, 10–15 times higher than background values. Such contamination reduces soil permeability and destroys beneficial microorganisms.

Experiments with regeneration technologies demonstrated that 75–80% of waste oil can be recovered through coagulation followed by adsorption purification. Recovered oils met 90% of the quality standards of base oils. Furthermore, biodegradable (plant oil-based) lubricants were studied. They degrade by 95–98% within 28 days, whereas conventional mineral oils only degrade by 15–20%.

Data suggest that if closed-loop oil collection systems are implemented in service centers, the amount of toxic substances released into the environment could decrease by an average of 450–500 tons per year in a single large district.

DISCUSSION

The study shows that mitigating the negative impact of LMs requires not only technical measures but also organizational and legal frameworks. Currently, the decentralized collection of waste oils leads to their disposal into sewer systems or open soil.

Key measures identified include:

Strengthening technical measures: Increase the hermetic sealing of vehicle lubrication systems and use modern filtration equipment to extend oil life and reduce waste.

Transition to biodegradable oils: Mandatory use of biodegradable lubricants in ecologically sensitive areas such as agriculture and forestry.

Develop utilization infrastructure: Install special reservoirs at service centers and establish centralized logistics for collecting waste oils.

Economically, regenerating waste oils consumes 2–3 times less energy than producing new oils, providing both environmental and financial benefits. Strengthening legislation against illegal disposal and offering tax incentives for recycling companies are also recommended. This comprehensive approach ensures environmental sustainability in the transport sector.

CONCLUSION

The study concluded that:

Used LMs are highly hazardous technogenic waste, with heavy metals and hydrocarbons causing long-term ecosystem damage.

Regeneration technologies allow for the recovery of waste oils, saving raw materials and reducing environmental pollution by up to 40%.

The adoption of biodegradable lubricants should be a key direction for sustainable transport.

The recommendations developed can improve ecological management in automobile transport enterprises. Future research will focus on studying the effectiveness of nanomaterials in waste oil recycling. Overall, establishing a modern system for managing LMs is crucial for achieving sustainable development goals.
