How we count

The ocean plastic counter is anchored to 11 million metric tons of plastic entering aquatic ecosystems every year, the central estimate from Breaking the Plastic Wave (Pew Charitable Trusts and SYSTEMIQ, 2020). Most of it arrives not as floating bottles but as microplastic fragments, lost fishing gear, and debris carried down rivers from mismanaged waste on land.

This number tracks new inflow, not the 100-plus million tons already circulating in the sea, and not the plastic waste that stays on land. Real flows surge with monsoon seasons and storms, while cleanup efforts pull small amounts back out; the counter smooths all of that into a steady annual pace. Read it as a modelled inflow, not a shipment-by-shipment measurement.

This counter is anchored to roughly 36.8 billion metric tons of fossil CO₂ per year, from the Global Carbon Project’s annual Global Carbon Budget. That synthesis combines energy statistics, cement production data, and atmospheric measurements, and it covers CO₂ from burning coal, oil, and gas plus cement manufacture.

It is one of the most tightly constrained numbers on this site, but still an estimate assembled from national reports and revised as better data arrives. It deliberately leaves out several things: other greenhouse gases such as methane and nitrous oxide (often expressed separately as CO₂-equivalent), and emissions from deforestation and land-use change, which the full carbon budget tracks on their own. Real emissions also rise and fall with seasons and economic shocks; the counter shows a smooth annual average.

The food waste counter uses around 1.3 billion metric tons of food lost or wasted each year, a long-standing FAO estimate echoed in UNEP’s Food Waste Index. That is roughly a third of all food produced for human consumption.

The figure spans the whole supply chain: crops left in fields, losses in storage and transport, supermarket spoilage, and food scraped off household plates. UNEP’s more recent work suggests household waste alone exceeds a billion tons, so estimates vary with method and scope. What the tonnage can’t show is the embedded cost: the water, land, labour, and fuel spent growing food that is never eaten, plus the methane it releases when it rots in landfill. A large share of household waste is still edible; confusion over use-by and best-before dates is one reason good food ends up in the bin.

This counter uses 62 million metric tons of e-waste generated worldwide, the headline figure from the Global E-waste Monitor 2024 (UNEP and the ITU), reflecting 2022 generation. E-waste covers discarded electrical and electronic equipment (phones, laptops, televisions, fridges, and a fast-growing category of small connected devices), measured by weight, not device count.

Only about a fifth of this material is formally collected and recycled. The rest is stored in drawers, informally dismantled, or exported, often with serious harm to the communities handling it. The counter measures generation, not disposal in a given year, and a single tonnage figure hides what matters most: the toxic lead and mercury inside, and the gold, copper, and rare earths that go unrecovered.

The textile waste counter is anchored to about 92 million metric tons of textile waste each year, a figure popularised by the Ellen MacArthur Foundation. It reflects the foundation’s finding that the equivalent of a rubbish truck of textiles is landfilled or burned roughly every second.

The number captures discarded clothing and textiles across their life: production offcuts, unsold stock, and worn-out garments. Less than 1% of material used to make clothing is recycled back into new clothing, so most of this waste is genuinely lost. What the tonnage doesn’t reveal is the upstream toll: the water and chemicals used in dyeing, and the microplastic fibres synthetic clothes shed into waterways with every wash.

This counter is built from sales data showing well over a million plastic bottles bought around the world every minute, reported by The Guardian using Euromonitor figures. Most are single-use PET drinks bottles, and global demand has only climbed since.

The number counts bottles purchased, not bottles littered, but the two are closely linked, because collection and recycling can’t keep pace with sales. Fewer than half are collected for recycling, and only a small share become new bottles. The rest are landfilled, incinerated, or escape into the environment, where they fragment into the microplastics now found from deep-sea sediment to human blood.

This is the counter that demands the most caution. It applies an estimated rate of 150 species lost per day (about 54,800 a year), a widely cited figure that traces back to United Nations and Convention on Biological Diversity messaging, usually quoted as a range of 18,000 to 55,000 species per year.

That rate comes from habitat-loss models, not a global register of the dead. Researchers estimate how many species live in an area, then project how many vanish as forests and wetlands shrink. Confirmed extinctions on the IUCN Red List are far fewer, because most species (insects, fungi, deep-sea life) are undescribed, and we rarely notice a loss until long after the last individual is gone.

Our anchor source, the IPBES Global Assessment, never publishes a clean “150 a day.” What it does say is starker in substance: around 1 million species face extinction, many within decades, at rates tens to hundreds of times above the natural background. The honest summary is that extinction is accelerating because of us, but pinning an exact daily count is scientifically contested. Read this counter as a modelled pace meant to prompt questions, not a verified tally.

The trees counter uses an estimate of about 15 billion trees felled each year, drawn from a landmark global tree census published in Nature by the Crowther Lab. The same study estimated Earth holds roughly 3 trillion trees, and that human activity has nearly halved the total since the dawn of agriculture.

The figure counts trees lost to logging, clearance, and land-use change, the gross number cut rather than the net change after replanting and regrowth. It is an annual average across very uneven realities: industrial clear-cutting, smallholder clearance for farmland, fuelwood gathering, and fire. A planted sapling is not ecologically equal to a felled old-growth tree, so even where tree counts recover, the carbon storage and habitat they provided can take decades or centuries to return.

This counter spreads about 540,000 hectares of EU land burned per year, the approximate 2006–2024 average implied by the European Commission’s Joint Research Centre: the record 1,079,538 hectares mapped in 2025 by the European Forest Fire Information System (EFFIS) was nearly double that earlier average.

EFFIS maps fires larger than about 30 hectares that include at least some forested area, so the true burnt total is a little higher. Real fire seasons are extremely lumpy (early springs, August heatwaves), not a smooth drip. Record years and quiet years both happen; 2025 was catastrophic, and mid-2026 was again running above the long-term average. Treat the counter as a year-to-date share of a multi-year average, not a live satellite feed. For the human and ecological cost of recent seasons, see Europe’s wildfires are torching the land.

This counter applies about 75 million metric tons of CO₂ equivalent per year, the greenhouse gas total the Initiative on GHG Accounting of War attributed to the fourth year of Russia’s full-scale invasion of Ukraine (24 February 2025 – 23 February 2026). Cumulative emissions over four years reached roughly 311 million tCO₂e.

The annual figure bundles warfare fuel use, landscape fires sparked by combat, damaged energy infrastructure, civil aviation rerouting, refugee movement, and carbon-intensive reconstruction. It is an accounting estimate assembled from activity data and emission factors, not a continuous sensor network, and it does not include the separate Iran conflict emissions covered in our article on the climate cost of the Ukraine and Iran wars. Intensity rises and falls with offensives, fire seasons, and rebuild waves; the counter shows a smooth year-to-date share of that published annual pace.

This counter uses 1.6 billion metric tons of municipal solid waste sent to landfill each year, derived from the World Bank’s What a Waste 2.0. The world generates around 2 billion tons of municipal waste annually, and roughly a third of it is landfilled; the rest is openly dumped, burned, composted, or recycled.

The figure covers household and municipal waste only. It excludes industrial, construction, agricultural, and mining waste, which together dwarf household trash by volume. It also can’t fully capture open dumping in places without formal collection, so the true tonnage of buried material is likely higher. Without major changes, the World Bank projects municipal waste rising by roughly 70% by 2050.

This counter is built from a global production rate of roughly 103 million barrels of petroleum and liquid fuels per day, tracked by the U.S. Energy Information Administration. Spread across the year, that is around 38 billion barrels: crude oil plus condensates and other liquids.

It measures what is pumped out of the ground, not what is burned, though almost all of it is ultimately combusted into the CO₂ tracked elsewhere on this site. Production responds to price, OPEC decisions, and demand shocks, so the real daily figure wobbles where the counter shows a smooth average. The number is also a useful reminder that climate impact begins at extraction: every barrel represents emissions already committed, plus the local pollution and habitat disruption of drilling itself.

This counter uses an estimate of about 4.5 trillion cigarette butts littered worldwide each year, a figure cited by the World Health Organization in its work on tobacco and the environment. Cigarette butts are consistently the single most collected item in beach and street cleanups.

The number reflects filters discarded into the environment, not total cigarettes smoked. The catch most people miss: cigarette filters are made of cellulose acetate, a plastic. They don’t biodegrade so much as fragment into microplastics, and a single soaked butt leaches nicotine, heavy metals, and other toxins that can poison fish in tests. Because littering is so casual and dispersed, this is one of the hardest waste streams to measure precisely, but its scale and persistence are not in doubt.

This counter is anchored to roughly 431 million metric tons of plastic produced each year, in line with Plastics Europe’s Plastics - the Facts. The overwhelming majority is made from fossil fuels, and annual production has roughly doubled since the early 2000s.

Crucially, this measures new plastic made, not plastic recycled or thrown away. Most of it is destined for short lives: around 40% becomes packaging used once and discarded within weeks. Recycled material still meets only a small fraction of demand, so production keeps drawing on virgin oil and gas. Because nearly everything made eventually becomes waste, this number is the upstream tap behind almost every other plastic statistic on this site, including the ocean and bottle counters.

This counter uses an estimate of around 100 billion garments produced each year, a figure highlighted by the Ellen MacArthur Foundation and widely used across fashion-industry analysis. Production has roughly doubled since 2000, driven by fast fashion’s compressed trend cycles.

The number counts items manufactured, not items kept or worn. Clothing utilisation (how many times a garment is worn before disposal) has fallen sharply, so more is made and each piece is used less. A growing share is cheap synthetic apparel designed for a handful of wears. Pairing this counter with the textile-waste figure tells the whole story: a linear take-make-dispose system in which production accelerates while the share recycled into new clothing stays close to zero.

This counter uses an estimate of roughly 405 million metric tons of human-caused methane per year, in the range tracked by the IEA Global Methane Tracker and the Global Carbon Project for total anthropogenic emissions. The main sources are agriculture (especially livestock and rice), fossil fuel production, and decomposing waste in landfills.

Methane matters out of proportion to its tonnage: over 20 years it traps roughly 80 times more heat than CO₂, but it breaks down within about a decade, so cutting it slows warming faster than almost any other action. The figure excludes natural sources like wetlands, and energy-sector leaks in particular are hard to measure precisely, with satellites repeatedly finding emissions higher than official reports. That makes methane both a major risk and one of the clearest near-term opportunities.

This counter uses an estimate of about 100,000 metric tons of fishing gear lost or abandoned at sea each year, drawn from peer-reviewed work by Wilcox and colleagues synthesising global fishing data. “Ghost gear” includes nets, lines, traps, and pots that are lost in storms, snagged, or deliberately discarded.

The number reflects gear entering the ocean, not the far larger mass already drifting there. Ghost gear is uniquely destructive: built to catch and kill, it keeps doing so for decades after it is lost, trapping fish, turtles, seabirds, and marine mammals in a cycle of “ghost fishing.” It is also a major source of ocean plastic, since modern nets are made from durable synthetic rope. Estimates carry wide uncertainty because losses happen out of sight, far offshore.
