# Sierra Leone: Greenhouse Gas and Air Pollutant Emissions

**Publisher:** Climate TRACE · **Source:** [HDX](https://data.humdata.org/dataset/sle-climate-trace) · **License:** `cc-by` · **Updated:** 2026-03-30

## Abstract

Climate TRACE is a non-profit coalition of organizations building a timely, open, and accessible inventory of exactly where greenhouse gas emissions are coming from. Climate TRACE estimates greenhouse gas (GHG) and air pollutant emissions for over 2.7 million sources (from over 744 million assets), and every single country globally.

The Climate TRACE emissions inventory includes:
- Annual country-level emissions by sub-sector and by gas beginning in 2015
- Monthly source-level emissions by sub-sector and gas beginning in 2021 and confidence
- Emissions source ownership where and when available.

Each row in this dataset represents time-series observations. Data was last updated on HDX on 2026-03-30. Geographic scope: **SLE**.

## Variables

**Geographic** — `year` (range 2024.0–2026.0), `emissionsquantity` (range 0.0–9573.6945).

**Temporal** — `month` (range 1.0–12.0).

**Identifier / Metadata** — `full_name` (Sierra Leone, Northern Province, SLE, Western Province, SLE), `id` (SLE, SLE.2_1, SLE.4_1), `level_0_id` (SLE), `level_1_id` (SLE.2_1, SLE.4_1, SLE.3_1), `name` (Sierra Leone, Northern Province, Western Province) and 2 others.

**Other** — `level` (range 0.0–1.0), `sector` (agriculture, transportation, waste), `gas` (ch4).

## Quick Start

```python
from datasets import load_dataset

ds = load_dataset("electricsheepafrica/africa-sle-climate-trace")
train = ds["train"].to_pandas()
test = ds["test"].to_pandas()

print(train.shape)
train.head()
```

## Curation

Raw data was downloaded from HDX via the CKAN API and converted to Parquet. Column names were lowercased and standardised to snake_case. Common missing-value markers (`N/A`, `null`, `none`, `-`, `unknown`, `no data`, `#N/A`) were unified to `NaN`. 1 column(s) with >80% missing values were removed: `level_2_id`. 4,214 exact duplicate rows were removed. The dataset was split 80/20 into train and test partitions using a fixed random seed (42) and saved as Snappy-compressed Parquet.

---

## Limitations

- Data originates from Climate TRACE and has not been independently validated by ESA.
- Automated cleaning cannot correct for misreported values, definitional inconsistencies, or sampling bias in the original collection.
- The following columns have >20% missing values and should be treated with caution in modelling: `level_1_id`.
- Refer to the [original HDX dataset page](https://data.humdata.org/dataset/sle-climate-trace) for the publisher's own methodology notes and caveats.
