The Road Management System in Bangladesh.

 

The Road Management System in Bangladesh.

Introduction

The road transport system is the lifeline of Bangladesh’s economy and social structure. Almost 80% of the country's passenger and freight movement depends on roads. Over the years, the government has expanded the road network, connecting rural and urban areas, boosting trade, and supporting industrial growth. However, despite these achievements, Bangladesh continues to suffer from a poor road management system, resulting in congestion, accidents, unsafe conditions, and inefficiency in transport operations.

The road management crisis is not just a technical problem but a systemic governance issue. While multiple factors — such as poor infrastructure, inadequate maintenance, lack of planning, and rapid urbanization — contribute to the situation, the primary reason lies in weak institutional coordination and governance failures. This essay explores in detail the root causes, institutional challenges, and the consequences of weak governance in road management, along with recommendations for reforming the system in Bangladesh.

 

Overview of the Road Management System in Bangladesh

Bangladesh has a road network of approximately 400,000 kilometers, comprising national, regional, and rural roads. The Roads and Highways Department (RHD) manages the national and regional highways, while the Local Government Engineering Department (LGED) oversees rural roads. The Bangladesh Road Transport Authority (BRTA) regulates vehicles, drivers, and road transport operations. The Traffic Police and Dhaka Transport Coordination Authority (DTCA) are responsible for enforcement and coordination in metropolitan areas.

Despite the involvement of several agencies, road management in Bangladesh remains fragmented. Roads are often poorly maintained, traffic regulations are weakly enforced, and safety conditions are inadequate. This fragmentation of authority and overlapping jurisdiction are central to the problem.

Main Reason: Weak Institutional Coordination and Governance

The core reason for Bangladesh’s poor road management system is weak institutional coordination combined with governance deficiencies. The responsibilities for road construction, maintenance, regulation, and enforcement are divided among multiple ministries and agencies that rarely work together effectively. This lack of coordination results in inefficiency, poor planning, duplication of efforts, and widespread corruption.

Let’s analyze this main cause in depth and explore how it manifests through several interconnected issues.

1. Overlapping Institutional Responsibilities

The biggest challenge lies in the fragmented nature of road governance. The RHD, LGED, BRTA, DTCA, and Police operate under different ministries with separate mandates. For example:

• RHD constructs and maintains national and regional highways.
• LGED handles local roads under the Ministry of Local Government.
• BRTA manages vehicle registration, driver licensing, and road safety awareness under the Ministry of Road Transport and Bridges.
• Traffic Police enforce traffic laws under the Ministry of Home Affairs.
• DTCA coordinates transport planning in Dhaka under yet another administrative structure.

This multi-agency arrangement creates confusion, weak accountability, and limited cooperation. As a result, projects often overlap or conflict — for instance, roads built without proper drainage, signage, or safety audits, because one agency built the road and another was supposed to maintain or regulate it.

The absence of a single lead authority for road management means decisions are delayed, responsibilities are blurred, and maintenance suffers.

2. Corruption and Political Influence

Corruption is a deep-rooted problem in Bangladesh’s public sector, and the road management system is no exception. Weak governance allows corruption at multiple levels, including:

• Issuing driving licenses without proper testing or training.
• Granting vehicle fitness certificates to unfit and unsafe vehicles.
• Manipulating tender processes for road construction and maintenance projects.
• Bribery in enforcement, where violators often escape fines through informal payments.

This culture of corruption directly undermines road safety and management quality. Many road accidents occur because of unqualified drivers, poorly maintained vehicles, or substandard construction materials — all linked to corrupt practices. Political influence further worsens the situation. Transport owners’ associations and labor unions often have political affiliations. As a result, enforcement authorities hesitate to take strict action against violations, fearing backlash or political pressure.

3. Poor Planning and Policy Implementation

Bangladesh has several road transport policies, such as the National Integrated Multimodal Transport Policy (NIMTP) and the National Road Safety Strategic Action Plan (2021–2030). However, the implementation of these policies is weak due to poor inter-agency communication and lack of accountability mechanisms.

Long-term transport planning is often neglected in favor of short-term infrastructure projects aimed at political gain. Roads are frequently constructed without proper feasibility studies, environmental assessments, or safety audits. Maintenance budgets are either insufficient or diverted, leading to rapid deterioration of newly built roads.

Moreover, road expansion projects often ignore future traffic growth, non-motorized transport needs, and pedestrian facilities, creating unsafe and congested conditions.

4. Lack of Technical Expertise and Manpower

Effective road management requires specialized knowledge in transport engineering, urban planning, and traffic management. However, Bangladesh faces a severe shortage of qualified professionals in these areas.

In many cases, administrative officials — rather than trained engineers or planners — make technical decisions about road design, traffic systems, and safety features. This results in roads that are poorly designed, lack proper drainage, or are unable to handle mixed traffic flow.

The absence of professional training and research-based decision-making has hindered the development of a modern and efficient road management framework.

5. Inadequate Maintenance and Monitoring

Maintenance is one of the weakest aspects of road management in Bangladesh. Once a road is constructed, it often receives little attention until it becomes severely damaged. Factors such as overloaded vehicles, poor drainage, and substandard materials accelerate deterioration.

Although the government allocates funds for road maintenance, corruption and inefficiency mean that much of this money is wasted. Lack of systematic monitoring and quality control further exacerbates the problem.

For example, many highways develop potholes within months of completion due to the use of low-quality materials or improper construction supervision. The failure to conduct periodic maintenance leads to much higher repair costs later and contributes to accidents and traffic congestion.

 

 

 

6. Weak Law Enforcement and Traffic Management

The road management crisis is also reflected in poor traffic regulation. Traffic police are often understaffed, undertrained, and underequipped. Manual traffic control, absence of digital monitoring, and limited surveillance make enforcement inconsistent.

Moreover, penalties for traffic violations are low, and corruption within the police force enables offenders to escape punishment. Many cities lack a proper traffic signal system, and where signals exist, they are often ignored by drivers and pedestrians alike.

Without strict enforcement and a culture of compliance, even the best road infrastructure cannot function safely or efficiently.

7. Lack of Data and Research

Accurate data is essential for managing any road network. Bangladesh lacks a comprehensive and reliable database on road conditions, accidents, and traffic patterns.

Agencies collect data in isolation and often fail to share it with others. This lack of coordination prevents evidence-based policymaking and makes it difficult to identify accident-prone areas or evaluate the effectiveness of safety measures.

Without accurate data, resource allocation and maintenance planning become arbitrary and inefficient.

8. Rapid Urbanization and Unplanned Growth

Uncontrolled urban expansion has placed enormous pressure on road infrastructure, especially in Dhaka and Chattogram. Population growth and rising vehicle ownership have outpaced the capacity of existing roads.

Unplanned development, roadside markets, illegal parking, and encroachments have narrowed roadways, reducing traffic flow efficiency. Urban roads often serve multiple conflicting purposes — transport, vending, parking, and pedestrian movement — without clear zoning or management.

The absence of coordinated urban transport planning contributes heavily to poor road conditions and persistent traffic congestion.

Consequences of Weak Road Management

The consequences of poor road management are visible in daily life and national development indicators:

• High rate of road accidents: Bangladesh records over 5,000 official deaths annually due to road crashes; unofficial estimates are much higher.
• Economic loss: Road traffic crashes cost an estimated 2–3% of GDP each year.
• Reduced productivity: Traffic congestion and transport delays hinder economic efficiency.
• Public suffering: Citizens face long travel times, high transport costs, and safety risks.
• Environmental impact: Poorly managed traffic increases fuel consumption and emissions.

 

Recommendations for Improvement

To improve road management in Bangladesh, reforms must focus on governance, coordination, and capacity building. Key recommendations include:

1. Establish a Unified Road Management Authority: Create a single national agency to coordinate all aspects of road construction, maintenance, safety, and enforcement.
2. Enhance Transparency and Accountability: Introduce digital systems for licensing, vehicle registration, and road maintenance tracking to reduce corruption.
3. Strengthen Law Enforcement: Equip traffic police with modern technology, cameras, and electronic fine systems.
4. Ensure Proper Planning and Design: Conduct feasibility and safety studies before road construction.
5. Increase Maintenance Funding: Allocate adequate budgets and ensure transparent use of maintenance funds.
6. Promote Professional Training: Build capacity through specialized education and certification for engineers, planners, and enforcement officers.
7. Encourage Public Awareness: Educate citizens on road discipline, pedestrian safety, and traffic laws.
8. Use Data-Driven Decision Making: Develop a centralized database for road conditions and accident reporting.
9. Ensure more Training on driving, Safe Driving, Defensive driving and behavior both driver and their staff and also some training program for the passenger through media, web channel, Social Media daily awareness, signage and poster.
10. Implement some special law on fine, Penalties and disciplinary action both road user, driver and their staff or owner and the penalties and punishment should be as high as possible, because to something authentic and best for the society and country Intimidation is necessary.    

 We are living in a society where we are innovative, accountable and responsible both all these, We can make our country, society and civilization beautiful and led a better life for present and future. To ensure this Intimidation is one of the keys, as fear and Intimidation make us responsible, accountable to play the roles effectively with care.

 

Conclusion

In conclusion, the poor road management system in Bangladesh is primarily a consequence of weak institutional coordination and governance failures. The fragmentation of authority among multiple agencies, combined with corruption, lack of planning, inadequate expertise, and poor enforcement, has created a dysfunctional transport environment.

To build a safer and more efficient road network, Bangladesh must reform its institutional framework, ensure accountability, and embrace professional management and data-driven planning. Road management should not merely focus on building more roads but on managing them intelligently, transparently, and sustainably.

Only through strong governance, coordination, and public commitment can Bangladesh transform its road system into a safe, efficient, and reliable backbone for national development.

The beauty and universality of wild flower

 

Bangladesh, a land of evergreen beauty. Everywhere in this country, flowers and vines of various colors come to mind, like a green mass. In the midst of this mass, thousands of unknown types of wild flowers grow on the roadsides and bushes. They may not have social status, but the uniqueness and universality of all those flowers fascinate everyone and even stir up the environment.

Bangladesh, with its lush greenery and tropical climate, is home to a vibrant array of wildflowers that bloom along roadsides, adding bursts of color to the landscape. These flowers, often unnoticed, bring a natural charm to highways, village paths, and city edges.

One of the most common roadsideflowers is the Kashful (Saccharum spontaneum), a tall, feathery white grass that sways gracefully in the autumn breeze, painting the roadsides with a dreamy, silver glow. In spring and summer, the Krishnachura (Delonix regia) and Radhachura (Peltophorum pterocarpum) trees bloom with fiery red and golden yellow flowers, creating a stunning contrast against the green countryside.

The Shapla (Nymphaea nouchali), Bangladesh’s national flower, often blooms in roadside ponds and ditches, its delicate blue or white petals floating peacefully on water. Meanwhile, the bright Dhulkalmi (Ipomoea carnea), with its soft purple trumpet-shaped flowers, thrives in damp areas along the roads, adding to the wild beauty.

All of those beautiful and monarchical flowers, around Bangladesh, we found a great number of wild flowers which have no name, but the beauty and personality of those flowers are remarkable and unique. The honey bees and Insects, symbolic of many heavenly beauties whose names are unknown, are always roaming around, collecting the nectar and fragrance of those flowers.

In polite society, such beauty may not be appreciated, but to those who appreciate the true qualities of nature, this wildflower is valued from the depths of the heart, where there is no vested interest. 

Despite growing without care or cultivation, these flowers contribute to biodiversity, attract pollinators, and enhance the scenic beauty of Bangladesh’s roadsides. Their resilience in harsh conditions is a reminder of nature’s ability to flourish even in the most unexpected places.

Nature nurture them with  passionate love and affection- They are creation of Good Earth Nurturing by Nature, because they are natural where artificialism is extremely prohibited.

How do you solve for carbon footprint?

Calculating a carbon footprint involves quantifying the greenhouse gas (GHG) emissions associated with a specific activity, individual, product, or organization. It is measured in carbon dioxide equivalents (CO₂e), which standardizes the impact of various greenhouse gases.

General Steps to Calculate Carbon Footprint

1. Define the Scope

Identify what you are measuring:

• Scope 1: Direct emissions (e.g., fuel combustion, company vehicles).
• Scope 2: Indirect emissions from purchased energy (e.g., electricity).
• Scope 3: Indirect emissions from the value chain (e.g., production of raw materials, waste, business travel).

For individuals, this includes transportation, home energy use, diet, and consumption habits.

2. Identify Emission Sources

List all activities or processes that produce GHGs. Common sources include:

• Energy usage (electricity, natural gas, heating oil).
• Transportation (cars, public transit, flights).
• Waste generation.
• Consumption (food, goods, and services).

3. Gather Activity Data

Collect data related to the activities. Examples include:

• Energy use: Kilowatt-hours (kWh) of electricity or cubic meters of natural gas.
• Transportation: Kilometers traveled and vehicle fuel efficiency.
• Diet: Types and amounts of food consumed.
• Waste: Quantity of waste generated and recycling rates.

4. Apply Emission Factors

Use emission factors to convert activity data into CO₂e. Emission factors are standardized values that specify the GHG emissions per unit of activity. For example:

• Electricity: Emissions depend on the energy mix of your region.
• Transportation: Emissions depend on fuel type and efficiency (e.g., gasoline emits ~2.31 kg CO₂ per liter).
• Food: Meat has higher emission factors than plant-based foods.

Sources for emission factors include:

• IPCC (Intergovernmental Panel on Climate Change).
• National government databases (e.g., EPA in the U.S., DEFRA in the UK).
• Tools like calculators or databases from trusted organizations.

5. Calculate Total Emissions

Multiply the activity data by the emission factors for each source and sum the results:

Carbon Footprint=∑ (Activity Data × Emission Factor) \text {Carbon Footprint} = \sum (\text {Activity Data} \times \text {Emission Factor})

6. Interpret and Act

• Break down the footprint by category to identify major contributors.
• Use this information to target reductions in high-impact areas.

Tools and Resources

• Online Calculators: Tools like the Carbon Footprint Calculator and CoolClimate Calculator provide an easy way to estimate personal or organizational footprints.
• Software: For businesses, specialized software ( Sphera, Simapro) can handle complex calculations.
• Consultants: Professional services for organizations needing in-depth analysis.

Which gas is not a greenhouse gas?

A gas that is not a greenhouse gas does not significantly absorb and trap heat in the Earth's atmosphere. Examples include:

• Nitrogen (N₂): Makes up about 78% of Earth's atmosphere and is not a greenhouse gas because it does not absorb infrared radiation.
• Oxygen (O₂): Constitutes about 21% of the atmosphere and also does not act as a greenhouse gas for the same reason.
• Argon (Ar): An inert noble gas that does not interact with infrared radiation and is not a greenhouse gas.

In contrast, greenhouse gases (like carbon dioxide, methane, nitrous oxide, and water vapor) absorb and re-radiate infrared radiation, contributing to the greenhouse effect and global warming.

What is the largest source of CO2 emissions?

The largest source of CO₂ emissions globally is the burning of fossil fuels, which accounts for the majority of carbon dioxide released into the atmosphere. Here’s a breakdown of the primary sources:

Global Context

Among fossil fuels, coal is the largest contributor, followed by oil and natural gas. Transitioning to renewable energy, improving energy efficiency, and reducing reliance on fossil fuels are critical steps to reducing CO₂ emissions.

What are the 10 main greenhouse gases?

The 10 main greenhouse gases (GHGs) in Earth's atmosphere, ranked by their global warming potential (GWP) and their impact on climate change, include both naturally occurring and human-made gases. Here's a list of the most significant ones:

1. Carbon Dioxide (CO₂)

• Source: Fossil fuel burning (coal, oil, natural gas), deforestation, cement production, and some industrial processes.
• Global Warming Potential (GWP): 1 (used as the baseline for GWP comparison).
• Impact: The most significant greenhouse gas in terms of volume and human activities.

2. Methane (CH₄)

• Source: Agriculture (especially livestock), landfills, oil and gas extraction, wetlands, and biomass burning.
• GWP: 25-28 times greater than CO₂ over 100 years.

• Impact: The most abundant greenhouse gas, but its concentration is primarily controlled by temperature.

5. Ozone (O₃)

• Source: Created by chemical reactions in the atmosphere involving pollutants like nitrogen oxides and volatile organic compounds (VOCs).
• GWP: Varies; typically considered much lower than CO₂ in terms of direct warming.
• Impact: Important in the stratosphere for blocking UV rays but a potent GHG in the lower atmosphere (troposphere).

6. Chlorofluorocarbons (CFCs)

• Source: Industrial solvents, refrigerants, and air conditioning.
• GWP: 4,750 to 10,900 times greater than CO₂.
• Impact: Highly potent, long-lived GHGs, and also contribute to ozone depletion.

7. Hydrofluorocarbons (HFCs)

• Source: Refrigerants and air conditioning systems (as a replacement for CFCs).
• GWP: 12 to 14,000 times greater than CO₂, depending on the specific compound.
• Impact: Strong GHGs with a significant but temporary atmospheric lifetime.

8. Perfluorocarbons (PFCs)

• Source: Industrial processes like aluminum production and electronics manufacturing.
• GWP: 7,390 to 17,340 times greater than CO₂.
• Impact: Very potent GHGs with long atmospheric lifetimes.

9. Sulfur Hexafluoride (SF₆)

• Source: Electrical equipment like circuit breakers and insulating equipment.
• GWP: 23,500 times greater than CO₂.

Summary of Global Warming Potentials (GWP) over 100 years:

• CO₂ (baseline): 1
• CH₄: 25-28
• N₂O: 273
• CFCs, HFCs, PFCs, SF₆, NF₃: Thousands to tens of thousands greater than CO₂

Each of these gases contributes differently to global warming, depending on its concentration in the atmosphere, lifetime, and warming potential. While CO₂ is the most abundant and well-known, gases like methane and HFCs, though less abundant, are much more effective at trapping heat.

Where is carbon found on Earth?

Carbon is found in various forms and locations across the Earth, playing a crucial role in the planet's ecosystems, climate, and life processes. The major reservoirs of carbon are as follows:

1. The Atmosphere

• Form: Carbon dioxide (CO₂) and methane (CH₄).
• Role: These gases are key components of the greenhouse effect and play a vital role in regulating Earth’s temperature. While the atmosphere contains a relatively small amount of carbon, it is crucial for the planet’s climate system.

2. The Oceans

• Form: Dissolved CO₂, bicarbonate ions (HCO₃⁻), and carbonates.
• Role: Oceans are the largest carbon sink on Earth, absorbing about a quarter of human-made CO₂ emissions. The carbon is stored in the form of dissolved CO₂, marine organisms (like plankton), and in sediments (such as coral reefs and deep-sea carbonates).

3. The Lithosphere (Earth’s Crust)

• Form: Carbonates (e.g., limestone, marble), fossil fuels (coal, oil, natural gas), and organic carbon in soil.
• Role: The Earth’s crust stores vast amounts of carbon in minerals like limestone (calcium carbonate) and fossil fuels, which were formed over millions of years. Carbon is also stored in soil as organic matter.

4. Living Organisms (Biosphere)

• Form: Organic carbon in plants, animals, and microorganisms.
• Role: All living organisms are carbon-based, as carbon is a fundamental building block of life (e.g., proteins, DNA, fats). Plants capture carbon through photosynthesis, and animals release carbon through respiration.

5. Fossil Fuels

• Form: Coal, oil, and natural gas.
• Role: Fossil fuels are concentrated reservoirs of carbon, formed from ancient plant and animal matter that has been compressed and heated over millions of years. Burning these fuels for energy releases carbon back into the atmosphere as CO₂.

6. Soil and Peatlands

• Form: Organic carbon in soil, peat, and humus.
• Role: Soils contain significant amounts of carbon in the form of decomposed plant and animal material. Peatlands, or bogs, store carbon for millennia due to slow decomposition in waterlogged conditions.

7. The Cryosphere (Polar Regions)

• Form: Organic carbon in permafrost.
• Role: Permafrost, the permanently frozen ground in polar regions, contains large amounts of carbon that were trapped in plant material thousands of years ago. As the climate warms, there is concern that thawing permafrost will release this stored carbon as methane or CO₂.

Carbon Cycle:

Carbon is constantly cycling between these reservoirs through natural processes, such as:

• Photosynthesis (plants and algae absorb CO₂ and release oxygen).
• Respiration (plants and animals release CO₂ into the atmosphere).
• Decomposition (breakdown of organic matter by microbes).
• Weathering of rocks (carbonates release CO₂ into the atmosphere).
• Volcanic activity (releases CO₂ stored in the Earth's crust).

Thus, carbon is widely distributed across different Earth systems—atmosphere, oceans, land, and living organisms—and its movement between these reservoirs is central to maintaining Earth’s climate and supporting life.

Where is carbon found on Earth?

Carbon is found in various forms and locations across Earth, playing an essential role in life processes and the planet's climate system. It is stored in both living and non-living systems and cycles through the Earth's environment in a complex process known as the carbon cycle. Below are the main reservoirs of carbon on Earth:

1. The Atmosphere

• Form: Carbon dioxide (CO₂) and methane (CH₄).
• Location: Carbon is present as gases in the Earth's atmosphere, where it plays a major role in the greenhouse effect and influences the climate. CO₂ is the most abundant greenhouse gas produced by human activities, while CH₄, although less abundant, is much more effective at trapping heat.

2. The Oceans

• Form: Dissolved CO₂, bicarbonate ions (HCO₃⁻), and carbonates (CaCO₃).
• Location: Oceans store a large amount of carbon, both in dissolved forms and in marine life. The surface waters absorb carbon dioxide from the atmosphere, while deep-sea waters and sediments hold carbon for long periods. Marine organisms like plankton also capture carbon, which can be stored in the form of shells or other biological material.

3. The Lithosphere (Earth’s Crust)

• Form: Carbonates (e.g., limestone, marble), fossil fuels (coal, oil, natural gas), and organic carbon in soils.
• Location: Carbon is stored in the Earth’s crust in the form of fossil fuels, which are the remains of ancient plants and animals. Limestone and other carbonate rocks, which contain carbon as calcium carbonate (CaCO₃), also store significant amounts of carbon. Carbon can remain locked in these forms for millions of years.

4. Living Organisms (Biosphere)

• Form: Organic carbon (proteins, carbohydrates, fats, DNA, etc.).
• Location: All living organisms are carbon-based. Carbon is a fundamental element in the structure of life and is found in the tissues of plants, animals, fungi, and microorganisms. Plants absorb CO₂ from the atmosphere during photosynthesis, while animals consume plants or other animals, moving carbon through the food chain.

5. Soil and Peatlands

• Form: Organic carbon in soil, peat, and humus.
• Location: Soils contain large amounts of organic carbon, derived from decaying plant and animal material. Peatlands, which are waterlogged areas where organic material decomposes slowly, are significant carbon stores. Carbon in soil can remain stored for centuries or longer, depending on the conditions.

6. The Cryosphere (Polar Regions)

• Form: Organic carbon in permafrost.
• Location: In polar regions, permafrost (permanently frozen ground) stores large amounts of carbon that has been trapped in plant material for thousands of years. As the climate warms, there is concern that thawing permafrost will release this stored carbon back into the atmosphere as CO₂ or methane, contributing to further climate change.

7. Fossil Fuels

• Form: Coal, oil, natural gas.
• Location: Fossil fuels are concentrated stores of carbon that were formed millions of years ago from ancient plant and animal matter under high pressure and temperature. When burned for energy, these fuels release carbon back into the atmosphere in the form of CO₂, a major contributor to anthropogenic (human-caused) carbon emissions.

8. Sediments

• Form: Organic material and carbonates.
• Location: Carbon is stored in sedimentary layers in the form of decayed organic material and calcium carbonate. This material can accumulate in riverbeds, ocean floors, and lake bottoms. Over geological time, some of this carbon is locked away in deep-sea sediments or rock formations.

Carbon Cycle:

Carbon continuously moves through these different Earth reservoirs in the carbon cycle, which involves:

• Photosynthesis: Plants absorb CO₂ from the atmosphere and convert it into organic carbon (carbohydrates).
• Respiration: Plants, animals, and microorganisms release CO₂ back into the atmosphere as they metabolize organic carbon.
• Decomposition: Decomposers break down dead organic matter, releasing carbon back into the soil or atmosphere.
• Ocean absorption: Oceans absorb atmospheric CO₂, which can be used by marine life or stored as carbonate minerals in the ocean floor.
• Fossil fuel formation: Over millions of years, carbon from plant and animal remains forms fossil fuels.
• Volcanic activity: Volcanoes release CO₂ that has been stored in the Earth's mantle and crust.

Summary:

Carbon is stored in several major reservoirs, including the atmosphere (as CO₂ and CH₄), oceans, Earth's crust (fossil fuels and carbonates), living organisms, soil, and permafrost. The carbon cycle ensures that carbon moves between these systems, human activities, particularly the burning of fossil fuels, have significantly altered this balance, leading to higher levels of CO₂ in the atmosphere and contributing to climate change.
