For decades, scientists have warned that super pollutants—highly potent greenhouse gases—are accelerating global warming faster than CO₂. Yet despite international pledges and technological advancements, emissions keep rising.

Super pollutants—including methane, hydrofluorocarbons (HFCs), black carbon, and tropospheric ozone—account for up to 45% of global warming. Unlike CO₂, which lingers in the atmosphere for centuries, these pollutants act fast, trapping heat at an intense rate. The good news? Cutting them now could bring near-instant climate relief.

So why aren’t we making faster progress? Despite existing solutions, efforts to curb super pollutant emissions remain severely underfunded and under-enforced. Methane alone, the second-biggest driver of global warming after CO₂, receives just 2% of total climate finance. Without urgent action, these emissions will continue fueling extreme weather, food shortages, and worsening air pollution.

Methane: The Fastest Way to Cool the Planet

Methane (CH₄) levels hit a record high in 2024 (1,942.94 parts per billion, NOAA) and is 86 times more potent than CO₂ over a 20-year period. It’s the second-biggest driver of climate change, responsible for 30% of global warming.

Where It Comes From

• Agriculture (40%) – Mainly from livestock digestion ("cow burps") and rice farming.
  ‍
• Fossil Fuels (35%) – Leaks from oil and gas drilling, pipelines, and coal mines.
  ‍
• Waste (20%) – Organic waste in landfills and wastewater releases methane as it decomposes.
  ‍

What’s Being Done

• The Global Methane Pledge – Over 150 countries have agreed to cut methane emissions by 30% by 2030.
  ‍
• Methane-tracking satellites are detecting leaks faster than ever.
  ‍
• New regulations require fossil fuel companies to plug leaks and stop venting gas into the atmosphere.
  ‍

Why isn’t methane declining?

• Fossil Fuel Expansion – Oil and gas extraction continues to grow, and many operations still allow methane to leak or be deliberately vented. While companies claim to be tackling methane leaks, enforcement and transparency remain weak.
  ‍
• Agriculture Demand – The global demand for meat and dairy is rising, fueling more methane from livestock digestion. Without major shifts in dietary patterns or innovations in livestock management, these emissions will continue.
  ‍
• Landfill Waste – Many cities lack proper waste management systems or methane capture facilities, allowing unchecked emissions.

Even though methane reduction is one of the most cost-effective ways to slow warming, the solutions are underfunded. Stronger regulations, financial incentives for emission reductions, and methane capture technologies could help curb emissions.

‍

✅ What You Can Do

• Reduce meat and dairy consumption – Less demand for livestock = lower methane emissions.
  ‍
• Cut food waste – Decomposing food in landfills is a huge methane source, so sort or compost instead.
  ‍
• Support clean energy – The natural gas industry is a top methane polluter. Switching to renewables helps.

Hydrofluorocarbons (HFCs): The Cooling Crisis
‍

HFCs are synthetic gases used in cooling systems. Some HFCs trap thousands of times more heat than CO₂.
‍

Where They Come From

• Air conditioners and refrigerators – Leaks from aging or poorly maintained cooling systems.
  ‍
• Aerosols and foams – Found in spray cans and insulation materials.
  ‍

What’s Being Done

• The Kigali Amendment – A global agreement phasing out HFCs in favor of cleaner alternatives.
  ‍
• Many companies are switching to low-impact refrigerants, like R-600a, which has a near-zero climate impact.
  ‍

Why isn’t HFC use dropping faster?

• Explosive Cooling Demand – Rising global temperatures and expanding middle-class populations, especially in hot regions, are driving massive demand for air conditioning and refrigeration. This growth often outpaces the adoption of alternative coolants.
  ‍
• Slow Industry Transition – Many manufacturers have been slow to switch to low-impact refrigerants like R-600a and CO₂-based systems, citing cost and regulatory uncertainty.
  ‍
• Illegal Trade – Some countries still produce and trade banned HFCs illegally, undercutting global reduction efforts.

Stronger enforcement of the Kigali Amendment and accelerating the adoption of alternative refrigerants are crucial to turning this trend around.

‍

✅ What You Can Do

• Choose appliances with natural refrigerants – Look for R-600a or R-290 labels.
  ‍
• Properly dispose of old fridges and AC units – Ensure refrigerants don’t leak into the atmosphere.
  ‍
• Use fans and passive cooling to reduce reliance on air conditioning.

Black Carbon (Soot): The Dirty Heat Trap

‍
Black carbon—commonly known as soot—warms the atmosphere up to 1,500x faster than CO₂ and accelerates ice melt in the Arctic and Himalayas. It also pollutes the air, and is globally linked to millions of premature deaths each year.
‍

Where It Comes From

• Diesel engines – Trucks, ships, and outdated vehicles.
  ‍
• Biomass burning – Wood stoves, agricultural burning, and wildfires.
  ‍

What’s Being Done

• Stronger emissions regulations for diesel engines and fuel standards.
  ‍
• Bans on open-field burning in agriculture.
  ‍
• Cleaner cooking solutions for developing regions.
  ‍

Why isn’t black carbon decreasing?

• Growing Wildfires – Climate change is fueling larger and more frequent wildfires, which release massive amounts of black carbon into the atmosphere.
  ‍
• Lack of Diesel Regulations – Many regions still lack strict emissions standards for diesel vehicles, construction equipment, and shipping, leading to continued black carbon emissions.
  ‍
• Traditional Cooking Methods – In many developing countries, wood, charcoal, and kerosene are still primary cooking fuels, leading to ongoing black carbon pollution.

Policies promoting cleaner transportation, wildfire prevention strategies, and widespread access to cleaner cooking technologies could make a big difference.

‍

✅ What You Can Do

• Avoid using wood-burning fireplaces and opt for cleaner heating options.
  ‍
• Use public transport, cycle, or walk to reduce diesel pollution.
  ‍
  
• Support policies that phase out diesel trucks and promote electric alternatives.

Tropospheric Ozone (O₃): The Hidden Pollutant

Ozone at ground level is both a greenhouse gas and a major air pollutant that worsens asthma and respiratory diseases.
‍

Where It Comes From

• Car exhaust and industrial pollution.
  ‍
• Methane emissions, which trigger ozone formation.
  ‍

What’s Being Done

• Low-emission zones in major cities are cutting traffic pollution.
  ‍
• Stricter industrial emission controls are reducing smog.
  ‍

Why isn’t ozone pollution falling?

• Rising Methane Levels – Methane is a key ingredient in the formation of tropospheric ozone, and since methane emissions are increasing, so is ozone pollution.
  ‍
• Vehicle and Industrial Emissions – Many cities, especially in rapidly developing countries, still rely heavily on fossil fuel-powered transportation and industry, leading to persistent ozone-forming pollutants.
  ‍
• Lack of Local Air Quality Action – While global climate agreements focus on CO₂ and methane, ozone pollution is often treated as a regional air quality issue, leading to fragmented and ineffective efforts to reduce it.

Tighter air pollution controls, cutting methane emissions, and promoting cleaner transportation options would help lower ozone levels.

‍

✅ What You Can Do

• Drive less – Walk, cycle, or use public transport when possible.
  ‍
• Avoid using gas-powered lawn equipment – Go electric or manual.
  ‍
• Support clean air policies that reduce industrial emissions.

2025 presents a rare opportunity to turn things around. Countries must submit updated climate plans (NDCs) under the Paris Agreement, detailing their emissions reduction targets. Strengthening commitments to cut super pollutants could make an immediate impact, reducing warming in the near term while long-term decarbonization efforts continue.

The technology and solutions exist—but implementation has lagged behind what’s needed. Prioritizing super pollutant reductions now could be one of the fastest and most effective ways to slow climate change while broader climate strategies take shape.

✅ Demand policy change – Push for stronger methane, HFC, and black carbon regulations.

✅ Make smarter choices – Cut food waste, reduce meat consumption, and choose cleaner appliances.

✅ Spread awareness – The more people know about super pollutants, the more pressure we can put on leaders.
