Organisationen 350.org lyfter just 350 ppm CO2 som det egentliga långsiktiga målet i det internationella klimatarbetet. De arbetar främst i USA, men har avdelningar i flera andra länder. För att komma ner till 350 ppm behöver vi dels så gott som helt få bort alla utsläpp av växthusgaser och dessutom utveckla teknik som även kan ta bort en del av de utsläpp som vi redan orsakat.

This animation shows not 400 ppm but 392 ppm (it is over two years old). Seeing air like this makes the proportion of CO2 seem small, which it is. The point is, it doesn't take very much - carbon dioxide is potent. Without the blue-circled particles, all plants would die and the surface of the Earth would be frozen. Gas concentration is measured in ppm, ‘parts per million’ by volume. If a room measuring 100m x 100m x 100m (1 million cubic metres) has 10 cubic metres of air replaced by a pure gas, then the gas concentration is expressed as 10ppm. A point sensor measures directly in ppm.

ppm = 1,000,000 c / s = 10 6 c / s (1). where .

Parts Per Million Defined. What is ppm? · Parts-per notations · Chemical concentration · Frequency stability · Decimal, percent, permille, ppm, ppb, ppt conversion calculator · Moles per liter (   First we must know that PPM is the English abbreviation for Pre Production Meeting, and technicality it is used in very specific fields, such as advertising, but only  Parts Per Million (ppm).

PPM is derived from the fact that the density of water is taken as 1kg/L = 1,000,000 mg/L, and 1mg/L is 1mg/1,000,000mg which is one part in one million (1 PPM). That is 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter.
