28 metrics with data for both countries. The solid line is Yemen; the dashed grey line is Azerbaijan.
Carbon dioxide released each year from burning fossil fuels and industry. The main driver of global warming. Global Carbon Budget via Our World in Data
Each person's share of their country's yearly CO2 emissions. A fairer way to compare countries of very different sizes. Global Carbon Budget via Our World in Data
How much warmer or cooler a country's year was compared with its 1991-2020 average. Watch the map turn red as you move the slider towards today. Copernicus Climate Change Service (ERA5) via Our World in Data
Methane traps around 80 times more heat than CO2 over 20 years. It comes mainly from livestock, rice, landfill and leaky fossil fuel infrastructure. Global Carbon Project / PRIMAP via Our World in Data
Every warming gas combined: CO2, methane and nitrous oxide, expressed as CO2-equivalents. Jones et al. / PRIMAP via Our World in Data
N2O is nearly 300 times more warming than CO2 and comes mostly from fertilised farmland and livestock. Jones et al. / PRIMAP via Our World in Data
Each person's share of the CO2 from flights taking off in their country, including passengers and freight. ICCT / Graver et al. via Our World in Data
How much energy each person uses in a year, across electricity, transport, heating and industry. Energy Institute / Ember via Our World in Data
The share of a country's electricity generated from solar panels. The fastest-growing energy source in history. Ember / Energy Institute via Our World in Data
The share of a country's electricity generated from wind turbines, onshore and offshore. Ember / Energy Institute via Our World in Data
The share of electricity still generated by burning coal, the most polluting fuel. The number that must reach zero first. Ember / Energy Institute via Our World in Data
The share of a country's electricity generated by burning oil. Rare on big grids, still common on islands. Ember via Our World in Data
The share of a country's electricity generated from natural gas, the least polluting fossil fuel but still a fossil fuel. Ember via Our World in Data
How much of a country's land is covered by forest. FAO via Our World in Data
People killed by floods, storms, droughts, heatwaves, earthquakes and other disasters each year. Single events dominate single years. IHME Global Burden of Disease via Our World in Data
Tracks extinction risk across all assessed species. 1 means no species at risk; falling values mean wildlife sliding towards extinction. IUCN / SDG 15.5.1 via Our World in Data
The share of a country's land under legal protection for nature. The global 30x30 target aims for 30% by 2030. World Bank / UNEP-WCMC via Our World in Data
Meat available for consumption per person. Livestock drives around 15% of global emissions and most deforestation. FAO via Our World in Data
Nitrogen applied per hectare of cropland. It feeds half the world, but runoff chokes rivers and coastal seas. FAO via Our World in Data
How much of a country's coastal waters are protected for nature. The global goal is 30% by 2030. UNEP-WCMC via Our World in Data
The share of people living in towns and cities. Urbanisation shapes energy use, land use and how people experience climate change. UN World Urbanization Prospects via Our World in Data
How much of a country's renewable freshwater is withdrawn each year. Above 25% counts as stressed; above 100% means drawing down reserves. FAO AQUASTAT (SDG 6.4.2) via Our World in Data
Each person's share of the country's renewable freshwater. Below 1,700 m³ is water stress; below 1,000 m³ is scarcity. FAO AQUASTAT via Our World in Data
Total rain and snow that fell over a country in a year, averaged across its land area. Copernicus Climate Change Service (ERA5) via Our World in Data
How much wetter (teal) or drier (brown) a country's year was compared with its 1961-1990 average. A simple drought and deluge signal. Derived from Copernicus ERA5 precipitation via Our World in Data
The share of people whose toilet waste is safely treated rather than left to contaminate water and soil. WHO/UNICEF JMP via Our World in Data
Average exposure to fine particles small enough to enter the bloodstream. The WHO guideline is 5 µg/m³. World Bank / van Donkelaar et al. via Our World in Data
Consumption of chemicals that destroy the ozone layer. Watch the map fade towards zero: the Montreal Protocol is the world's most successful environmental treaty. UN Environment Programme via Our World in Data
