Let agents query LCA background databases and published EPDs directly: find datasets, read details and GWP100, and pull inventories (LCI) and impact results (LCIA). Every result carries its source, version, system model, unit and a web link for human review.
In Claude Code:
/plugin marketplace add HiQ-AI/environmental-data
/plugin install environmental-data@environmental-data
For published EPDs, install epd-data@environmental-data instead. Then ask in
plain language, e.g. "find the GWP of low-voltage electricity on the East China
grid and list its inventory". The agent installs the pinned CLI and walks you
through a browser login. Codex CLI can use the same marketplace; see
installation.
| Plugin | Description |
|---|---|
| Environmental Data | Find and match Environmental Data data to user requirements, compare applicability and retrieve authorized details while preserving provenance and access limits. |
| EPD声明查询 | Find and match Published EPD Data data to user requirements, compare applicability and retrieve authorized details while preserving provenance and access limits. |
The database plugin ships the environmental-data-query skill and three roles:
data-searcher, data-matcher and data-reviewer. The EPD plugin ships
epd-query.
| Command | What it returns |
|---|---|
search |
Candidate datasets; filter by --sources source[:version], --model, --location |
lookup |
Dataset details: description, boundaries, GWP100, access decision, web link |
lci |
Cumulative inventory (elementary flows) of one dataset |
lcia |
Impact results; several datasets at once, one method, or process contributions |
methods |
LCIA methods and indicators of a source, for choosing lcia --method |
trace |
One layer of supply structure: up to three suppliers or consumers, each with its own key |
epd-data provides search and lookup for declarations. Eighteen background
databases are covered, including HiQLCD, CALCD, ecoinvent, Carbon Minds,
Agri-footprint, EF, USLCI, ELCD and worldsteel; see the
source inventory and the live
source directory.
Example (HiQLCD 1.5.0, low-voltage electricity, East China grid): search to LCIA
in about 3 seconds, GWP100 0.7314 kg CO2-eq/kWh, consistent across lookup,
lcia and process contributions.
- Every signed-in user gets values from free databases.
- Commercial values require an administrator to enable the account for
Environmental Data CLI, then one more
login. Values stay limited to the databases the account has licensed; restricted rows sayGRANT_REQUIRED. - Installing a plugin grants no credential or database license.
Each result keeps source, version, model, reference product and unit, geography
and a webUrl such as
https://www.hiqlcd.com/dataset/HiQLCD/1.5.0/CUT_OFF/<id>/<name>?dataset_ref=<key>.
Open it to check the same dataset on the website. Missing, restricted and
unavailable are different outcomes; do not rank values whose methods, models or
boundaries differ. Queries never import records, edit models or purchase access.
