What is Carbon Trading? How does it work?
Carbon emissions, primarily in the form of carbon dioxide (CO₂) and methane (CH₄), contribute to global warming, climate change, and sea-level rising which in turn increase the frequency and intensity of natural phenomena, and disasters like cyclones, floods, wildfire, drought, heatwave, etc. Reduction of carbon emissions has multifarious environmental, economic, social, and health benefits. Carbon trading is both a benefit and a mechanism for reducing carbon emissions. Here’s how it works and why it can be beneficial.
What is Carbon Trading
Carbon trading, also known as carbon emissions trading, is a market-based approach to reducing greenhouse gas (GHG) emissions. It allows countries, companies, or organizations to buy and sell permits that represent the right to emit a certain amount of carbon dioxide or other greenhouse gases. By putting a price on carbon emissions, it incentivizes participants to lower their emissions and invest in cleaner technologies.
Carbon emissions trading operates under a cap-and-trade system where governments or organizations set a limit (cap) on total emissions. Companies receive or buy carbon credits, which allow them to emit a certain amount of CO₂. If a company emits less than its allowance, it can sell its excess credits to others. If a company exceeds its limit, it must buy more credits or face penalties.
Carbon trading is a benefit of reducing emissions because it creates financial incentives for businesses to go green. However, it works best when proper regulations and transparency ensure that actual emission reductions occur.

What Is the Process of Carbon Credit Sale?
The process of selling carbon credits involves several steps, from generating the credits to finding buyers and completing the transaction. Here’s a step-by-step breakdown:
Carbon Credit Generation
A company or project must first reduce or remove greenhouse gas (GHG) emissions through activities like reforestation, renewable energy projects, or carbon capture. The emission reduction must be measured, verified, and certified by an independent third party.
Verification & Certification
The project must be validated by recognized carbon standards such as: Verified Carbon Standard (VCS), Gold Standard, Clean Development Mechanism (CDM), Climate Action Reserve (CAR), etc. These standards ensure that each credit represents one metric ton of CO₂ reduced or removed.
Registration on a Carbon Registry
Verified carbon credits are registered on platforms like: Verra, American Carbon Registry (ACR), Gold Standard Registry, etc. Each credit receives a unique serial number to prevent double counting.

Finding Buyers
There are two main types of carbon markets:
Compliance or Regulated Markets are created by government regulations to limit carbon emissions. Companies must buy carbon credits if they exceed their allowed emissions cap.
In the Cap-and-Trade system, governments set a maximum emission limit (cap). Companies emitting less than their limit can sell excess credits to others exceeding their cap.
Some countries impose a carbon tax, but companies can reduce their tax burden by purchasing credits.
Major Compliance Markets include the European Union Emissions Trading System (EU ETS), California Cap-and-Trade Program, China’s National ETS, Regional Greenhouse Gas Initiative (RGGI), etc.
In the Voluntary Carbon Markets (VCM) markets, companies and individuals buy carbon credits voluntarily to offset their emissions. These credits come from projects that remove or reduce CO₂ emissions, such as reforestation, renewable energy, and carbon capture.

Relentless assault on hearing: Dhaka’s noise pollution out of control, say experts
Noise pollution levels in Dhaka city are reaching alarming heights, severely impacting the daily lives of its residents. Increasing traffic, unnecessary honking, rampant use of loudspeakers, and other sources of high-decibel noise are disrupting the capital’s normalcy. Despite existing laws, there is a notable lack of effective enforcement.
Residents across Dhaka are facing significant health risks due to excessive noise. Many are experiencing hearing loss, with school and university students among the most affected. Children, the elderly, and patients are particularly vulnerable, with traffic police also unable to escape the noise onslaught.
Experts highlight that public awareness about the dangers of noise pollution remains low. Prof Ahmad Kamruzzaman Majumder of Stamford University’s Environmental Science Department pointed out, “Unnecessary honking, loudspeakers, and construction noise are making daily life unbearable. This issue is not just about physical health; it also affects mental well-being and even hampers urban plant reproduction and crop yields.”
Prof Majumder added that controlling rampant horn usage alone could reduce Dhaka’s noise pollution by 60%. However, poor law enforcement in this regard hinder progress. “We have laws, but their implementation is almost non-existent. For instance, the Noise Pollution Control Rules 2006 mandate quiet zones around schools, hospitals, and mosques, but these are rarely enforced.”
Motorists to be trained to control noise pollution: Environment Minister
Health professionals are raising alarms about the long-term impacts of noise pollution. Prof Dr Abul Bashar Mohammad Khurshid Alam, Director General (DG), Directorate General of Health Services (DGHS), explained, “Noise levels in Dhaka are more than double the acceptable limits, leading to serious physical and mental health issues. Beyond hearing loss, there is an increase in diabetes and heart complications. Pregnant women, children, and the elderly are particularly at risk. Exposure to noise levels of 120 decibels can cause immediate hearing damage, while consistent exposure to 85 decibels for two hours daily can gradually deteriorate hearing.”
Experts emphasize the need for long-term planning and stricter enforcement of existing laws. “Countries with advanced noise control measures impose fines for unnecessary horn usage. We need similar robust enforcement here,” Prof Majumder urged. He also called for increased public awareness and adherence to noise control measures, including avoiding unnecessary use of headphones.
The Center for Atmospheric Pollution Studies (CAPS) at Stamford University conducted a year-long study from April 2021 to March 2022, examining noise levels at ten locations in Dhaka. The research revealed that noise exceeded acceptable limits in all surveyed areas. Specifically, 96.7% of the time in quiet zones, 91.2% in residential areas, 83.2% in mixed-use areas, 61% in commercial areas, and 18.2% in industrial areas, the noise levels surpassed the standard thresholds.
Noise pollution awareness campaign: One-minute silence to be observed in Dhaka Oct 15
CAPS’s findings underscore the pervasive nature of noise pollution in Dhaka, with 82% of all monitored locations exceeding 60 decibels consistently. Despite the Noise Pollution Control Rules 2006, which set permissible noise levels at 45 decibels at night and 55 during the day for residential areas, and 60 decibels at night and 70 during the day for commercial areas, enforcement remains a significant challenge.
The situation in Dhaka demands immediate and comprehensive action. Strengthening legal frameworks, enhancing public awareness, and enforcing noise control measures are critical steps toward mitigating the city’s noise pollution crisis. Without decisive action, the health and well-being of Dhaka’s residents will continue to deteriorate under the relentless assault of noise pollution.

Last 12 months on Earth were the hottest ever recorded, analysis finds
The last 12 months were the hottest Earth has ever recorded, according to a new report by Climate Central, a nonprofit science research group.
The peer-reviewed report says burning gasoline, coal, natural gas and other fossil fuels that release planet-warming gases like carbon dioxide, and other human activities, caused the unnatural warming from November 2022 to October 2023.
Over the course of the year, 7.3 billion people, or 90% of humanity, endured at least 10 days of high temperatures that were made at least three times more likely because of climate change.
Western and Arab officials are gathering in Paris to find ways to provide aid to civilians in Gaza
"People know that things are weird, but they don't they don't necessarily know why it's weird. They don't connect back to the fact that we're still burning coal, oil and natural gas," said Andrew Pershing, a climate scientist at Climate Central.
"I think the thing that really came screaming out of the data this year was nobody is safe. Everybody was experiencing unusual climate-driven heat at some point during the year," said Pershing.
The average global temperature was 1.3 degrees Celsius (2.3 degrees Fahrenheit) higher than the pre-industrial climate, which scientists say is close to the limit countries agreed not to go over in the Paris Agreement — a 1.5 C (2.7 F) rise. The impacts were apparent as one in four humans, or 1.9 billion people, suffered from dangerous heat waves.
At this point, said Jason Smerdon, a climate scientist at Columbia University, no one should be caught off guard. "It's like being on an escalator and being surprised that you're going up," he said. "We know that things are getting warmer, this has been predicted for decades."

Here's how a few regions were affected by the extreme heat:
1. Extreme heat fueled destructive rainfall because a warmer atmosphere holds more water vapor, which lets storms release more precipitation. Storm Daniel became Africa's deadliest storm with an estimated death toll that ranges between 4,000 and 11,000, according to officials and aid agencies. Greece, Bulgaria, and Turkey also saw damages and fatalities from Storm Daniel.
2. In India, 1.2 billion people, or 86% of the population, experienced at least 30 days of elevated temperatures, made at least three times more likely by climate change.
3. Drought in Brazil's Amazon region caused rivers to dry to historic lows, cutting people off from food and fresh water.
4. At least 383 people died in U.S. extreme weather events, with 93 deaths related to the Maui wildfire event, the deadliest U.S. fire of the century.
5. One of every 200 people in Canada evacuated their home due to wildfires, which burn longer and more intensely after long periods of heat dry out the land. Canadian fires sent smoke billowing across much of North America.
6. On average, Jamaica experienced high temperatures made four times more likely by climate change during the last 12 months, making it the country where climate change was most powerfully at work.

"We need to adapt, mitigate and be better prepared for the residual damages because impacts are highly uneven from place to place," said Kristie Ebi, a professor at the Center for Health and the Global Environment at the University of Washington, citing changes in precipitation, sea level rise, droughts, and wildfires.
The heat of the last year, intense as it was, is tempered because the oceans have been absorbing the majority of the excess heat related to climate change, but they are reaching their limit, said Kim Cobb, a climate scientist at Brown University. "Oceans are really the thermostat of our planet ... they are tied to our economy, food sources, and coastal infrastructure."

Plastic Pollution: Harmful effects on human health and environment
Plastic pollution has emerged as one of the most pressing environmental issues of our time, posing significant threats to both human health and the environment. As we observe World Environment Day today (June 5, 2023), it is crucial to shed light on the harmful effects of plastic pollution and raise awareness about the urgent need for action. This global observance serves as a timely reminder that the choices we make today have far-reaching consequences for the well-being of our planet and future generations.
Harmful Effects of Plastic Pollution on Human Health
Plastic pollution has become a major environmental concern in recent years, and its impact on human health is a growing area of research. Here are some of the harmful effects of plastic pollution on human health.
Exposure to Microplastic
Microplastics, small plastic particles less than 5 millimeters in size, have infiltrated various aspects of our lives, including our food and water sources. These tiny particles are found in high concentrations in the oceans, freshwater bodies, and even the air we breathe. Seafood, such as fish and shellfish, often contain microplastics due to their ingestion of plastic debris in the marine environment. As a result, when we consume these contaminated seafood, we unknowingly ingest microplastics.

Microplastics can accumulate in our bodies over time, causing potential harm. These particles can pass through the intestinal wall and migrate to other organs, leading to inflammation, tissue damage, and disruption of normal cellular functions. Some studies suggest that microplastics may also have the potential to transport harmful chemicals and pathogens, further exacerbating health risks.
