Governments, international bodies, and industries are tackling pollution on multiple fronts simultaneously, from legally binding treaties and stricter drinking water standards to a rapid shift toward electric vehicles and renewable energy. The scale of action has accelerated sharply since 2020, with new regulations targeting chemicals that weren’t monitored a decade ago and clean energy reaching record levels. Here’s what’s actually happening right now.
Clean Energy Is Displacing Fossil Fuels
The single largest driver of air pollution globally is burning fossil fuels for electricity and heat. In 2024, low-carbon power sources (renewables plus nuclear) generated 40.9% of the world’s electricity, crossing the 40% threshold for the first time since the 1940s. Wind and solar combined now produce more electricity than hydropower, with wind at 8.1% and solar at 6.9% of the global mix. Solar alone is growing so fast that it led the record increase in renewables last year.
That still leaves nearly 60% of electricity coming from fossil sources, and heatwave-driven demand spikes actually caused a small increase in fossil generation in 2024. But the trajectory is clear: each year, new solar and wind capacity is added faster than demand grows, which means fossil fuels are gradually losing their share even as total electricity use rises.
Electric Vehicles Are Going Mainstream
Transportation is the other major source of air pollution in most countries. Electric car sales exceeded 17 million globally in 2024, representing more than 20% of all new cars sold. That’s roughly one in five. The International Energy Agency expects sales to top 20 million in 2025, pushing the share past 25%. Every electric car on the road eliminates tailpipe emissions of nitrogen oxides, particulate matter, and carbon dioxide in the communities where people actually breathe.
The shift is uneven. China, Europe, and parts of North America are driving most of the growth, while many developing countries still rely on older, more polluting vehicles. But as battery costs continue falling, the price gap between electric and gasoline cars is narrowing in markets where it once seemed insurmountable.
Cutting Methane Before It Spreads
Methane is a potent greenhouse gas that also contributes to ground-level ozone, a harmful air pollutant. The Global Methane Pledge now unites 159 countries plus the European Commission around a goal of cutting methane emissions 30% below 2020 levels by 2030. Individual countries are going further. Canada, for example, published draft regulations aiming to cut oil and gas methane by at least 75% from 2012 levels by 2030, and separate rules targeting landfill methane that would roughly halve those emissions by the same deadline.
Methane reductions are considered one of the fastest ways to slow warming because methane breaks down in the atmosphere within about a decade, unlike carbon dioxide, which persists for centuries. Fixing leaky pipelines, capping old wells, and capturing landfill gas are relatively straightforward compared to overhauling entire energy systems.
Removing Carbon Directly From the Air
A newer approach called direct air capture uses industrial facilities to pull carbon dioxide out of the atmosphere. About 84 plants (a mix of pilot and commercial facilities) are expected to be operational by the end of 2025, with a combined capacity of roughly 569,000 tonnes of CO2 per year. By 2032, companies project 114 facilities with a capacity between 2.1 and 5.4 million tonnes per year.
To put that in perspective, global CO2 emissions are measured in the tens of billions of tonnes annually. Direct air capture is still a tiny fraction of what’s needed, but the technology is scaling. Its real value right now is proving the engineering works, bringing costs down, and building the infrastructure for much larger deployment later.
Stricter Rules on “Forever Chemicals” in Water
Water pollution has gotten more attention as scientists have identified chemicals that persist in the environment for decades. The EPA finalized its first enforceable limits on PFAS, a group of synthetic chemicals found in everything from nonstick cookware to firefighting foam. These substances don’t break down naturally, earning them the nickname “forever chemicals,” and they’ve been linked to cancer, immune problems, and developmental issues.
The new rules set maximum levels of 4 parts per trillion for the two most common PFAS compounds (PFOA and PFOS) in public drinking water. Three additional PFAS chemicals are capped at 10 parts per trillion. The regulation also covers mixtures: if multiple PFAS are present together, their combined hazard must stay below a set threshold. These are extraordinarily low limits, reflecting how toxic these substances are even in tiny amounts. Public water systems across the United States will need to test for these chemicals and install treatment systems if levels exceed the new standards.
A Global Treaty on Plastic Pollution
Plastic waste contaminates oceans, soil, and drinking water on every continent. In 2022, the UN Environment Assembly passed a historic resolution to develop a legally binding international treaty on plastic pollution. Unlike voluntary pledges, this instrument would carry legal weight and address the full life cycle of plastic, from production and product design through disposal and cleanup.
An Intergovernmental Negotiating Committee has held sessions across five countries since late 2022, including meetings in Uruguay, France, Kenya, Canada, South Korea, and Switzerland. Negotiations have been complex. The most recent session, held in February 2026 in Geneva, did not advance substantive negotiations, reflecting deep disagreements between countries that produce oil (the raw material for most plastic) and those pushing for caps on production. The treaty remains a work in progress, but the fact that nearly every nation agreed to negotiate a binding instrument is itself a significant step. Previous efforts relied on voluntary commitments that produced limited results.
Making Producers Pay for Their Packaging
One of the most practical shifts in waste management is called extended producer responsibility, or EPR. The idea is simple: companies that create packaging and products are legally required to fund or manage the collection and recycling of that waste, rather than leaving it to taxpayers and municipal systems.
South Korea has run one of the most comprehensive EPR programs for years, covering a wide range of materials and achieving high recycling rates. India introduced mandatory EPR rules in 2022, requiring producers to meet specific collection and recycling targets with full implementation by 2028. The Philippines passed its own EPR Act the same year, mandating that large companies recover 80% of their plastic packaging by 2028. South Africa made EPR mandatory for packaging in 2021. In 2024, the UAE launched its first EPR pilot in Abu Dhabi and Dubai, covering electronics, batteries, and packaging.
North America is catching up at the state and provincial level. California now requires that 65% of all single-use plastic packaging be recycled by 2032. British Columbia has operated a full EPR program since 2014, consistently meeting or exceeding its recovery targets even for hard-to-recycle plastics. These laws shift the financial incentive: when companies bear the cost of dealing with their waste, they have a reason to design products that are easier to recycle in the first place.
Where the Gaps Remain
Despite this progress, global pollution levels are still rising in absolute terms. Air quality in many cities across South Asia, sub-Saharan Africa, and parts of Southeast Asia remains far above safe levels. Plastic production continues to increase year over year. And while renewable energy is growing fast, it hasn’t yet caused a sustained decline in total fossil fuel use because global energy demand keeps climbing.
The tools and policies described above are real, measurable, and in many cases accelerating. But they operate against a backdrop of rising population, rising consumption, and the sheer inertia of industrial systems built over a century. The difference between now and a decade ago is that the alternatives exist and are scaling. Whether they scale fast enough is the central question of the next ten years.
