The 4 key statistics that decide it
Only these place Solomon Islands on environment & sustainability — one vote each. Every value is the publisher’s own, read at the edition the Country Index 2026 used; the grey ticks are every other country it was compared with, lowest on the left.
Key 1 of 4
CO₂ Emissions per Capita
Global Carbon Project
Why it is a key: How much carbon dioxide a country's own fuel burning puts into the air for each person living there.

Solomon Islands beside its neighbours
A position reads best beside the countries around it. Every position below is a place among all 186 countries on environment & sustainability, never a place within the region.
Solomon Islands and Melanesia
Solomon Islands has no land border, so the table compares it with its sub-region. The standing is each country’s place among all 186 placed on the topic; the other columns are the publishers’ own values, read at the edition the standing used.

Solomon Islands on environment & sustainability: questions answered
Every answer is built from the numbers on this page, so none can say something the page does not.
How does Solomon Islands rank on environment & sustainability?
Solomon Islands is placed 7th of 186 countries on Environment & Sustainability in the Country Index 2026, from 2 of its 4 key statistics (CO₂ Emissions per Capita and Organic Agricultural Area). The position is this site’s ordering of published statistics, not a rank any publisher printed.
What is the latest CO₂ Emissions per Capita figure for Solomon Islands?
0.36 in 2024 (fossil CO₂ (tonnes per person)), according to Global Carbon Project. The world median in the same edition was 3.21.
What is the latest Organic Agricultural Area figure for Solomon Islands?
6.56 in 2024 (organic share of agricultural land (%)), according to Food and Agriculture Organization of the United Nations (FAO). The world median in the same edition was 0.725.
How have Solomon Islands’s environment & sustainability figures changed?
CO₂ Emissions per Capita fell from 0.516 in 2000 to 0.36 in 2024; Organic Agricultural Area rose from 3.76 in 2006 to 6.56 in 2024.
Which environment & sustainability statistics are missing for Solomon Islands?

What this topic does not measure
Air quality and biodiversity are not keys, because the site does not yet hold data for them that passes every test. Forest cover, farmland, farm emissions and the renewable share of electricity are published here as context. Exposure to natural hazards belongs to Risk & Resilience.
How the Environment & Sustainability standing is decided, step by step
A standing is a place in a list, not a mark out of anything. This one is part of the Country Index 2026, and it is worked out like this.
- A few key indicators decide it; the rest are context. 4 indicators on this topic are keys and 49 are charted alongside them without a vote. That split is the point: if every statistic voted, importing five more of one kind would quietly change what the topic is about.
- Each key is read at one edition. ⚠ The keys behind this standing do not all describe the same year — they run from 2023 to 2025, because publishers release on their own schedules. Read the standing as “how this country places now”, not as a snapshot of one year.
- Every country’s published value is turned into a place within that one key’s own field, and then expressed as a share of that field — how far down this key’s list the country sits, rather than how many countries are above it. Keys where a higher published number is worse (terrorism, hunger, disaster risk) are turned round first, so the good end is always the same end.
- Dividing by the field first is the whole reason this works. A place carries the size of its list inside it: 22nd of 44 and 108th of 215 are the same showing, and averaging the numbers 22 and 108 says loudly that they are not. Fields on this site run from about 44 countries to about 215, so averaging raw places would reward a country for happening to be measured in small ones. Dividing each place by its own field removes the size and leaves only the showing.
- The shares are averaged, plainly. One key, one vote — no key is weighted above another, because any weighting would be this site’s opinion presented as a measurement. Countries are then put in order by that average, and the average itself is never published. It is our arithmetic with nothing anchoring it, so printing it would invite it to be read as a measurement somebody made. The position it produces, the band, and the keys it was built from are all published instead — every one of them checkable against the tables on this page.
- A country needs 2 of this topic’s 4 keys — half, rounded up, and never fewer than 2. A standing built from one reading, printed beside one built from four, is two different things sharing a column heading. 186 countries clear the bar here.
- A key has to earn its vote every edition. It must measure at least 120 countries (below that it starts measuring who was surveyed rather than the world), it must not have more than 10% of its field tied at either end, and it must not repeat another key in the same topic — Spearman correlation above 0.92 counts as repeating. A topic needs at least 2 surviving keys to place anyone at all; this one has 4.
- A standing is relative, and the grouping is ours. It says where a country places against the others measured alongside it, so it moves when they move. The publishers listed on this page did not agree to be read together, and each measures its subject its own way: the underlying numbers are theirs, the ordering on top is this site’s — the same method as the rest of the Country Index, applied to one subject instead of all of them.
