Brunei Darussalam's PM2.5 air pollution, population exposed to levels exceeding WHO guideline value (% of total) was 0% in 2017, the latest year in the World Bank's World Development Indicators. That is down 1.77 percentage points from 1.77% in 2012.
Key figures
| Value | Year | |
|---|---|---|
| Latest | 0% | 2017 |
| Five years earlier | 1.77% | 2012 |
| Highest | 1.77% | 2012 |
| Lowest | 0% | 1990 |
| Average since 2010 | 0.66% | 2010–2017 |
| First recorded | 0% | 1990 |
Over five years it is down 1.77 percentage points from 1.77% in 2012. Since 1990 it is unchanged since 1990. The World Bank has no value for 16 of the years in between; the chart leaves those gaps open rather than joining across them.
What the numbers say
From 2010 to 2017 the straight-line trend is downward, about 0.32 percentage points a year. A straight line explains 71% of the movement over 8 observed years.

How it compares
In 2017, Brunei Darussalam had the 189th highest value of the 194 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures
Percent of population exposed to ambient concentrations of PM2.5 that exceed the WHO guideline value is defined as the portion of a country’s population living in places where mean annual concentrations of PM2.5 are greater than 10 micrograms per cubic meter, the guideline value recommended by the World Health Organization as the lower end of the range of concentrations over which adverse health effects due to PM2.5 exposure have been observed.
Limitations: Pollutant concentrations are sensitive to local conditions, and even monitoring sites in the same city may register different levels. Direct monitoring of PM2.5 is still rare in most parts of the world, and measurement protocols and standards are not the same for all countries. These data should be considered only a general indication of air quality, intended to inform cross-country comparisons of the health risks due to particulate matter pollution. The guideline set by the World Health Organization (WHO) for PM2.5 is that annual mean concentrations should not exceed 10 micrograms per cubic meter, representing the lower range over which adverse health effects have been observed.
Regional and income-group figures are computed by the World Bank as a weighted average.
