GHG inventory tenders
A greenhouse gas inventory is the starting point for almost every public climate plan, so inventory work appears at every level of government. Countries compile national inventories for their reporting under the UN climate convention; regions and cities build territorial inventories for their climate action plans; and hospitals, universities, utilities and agencies commission organisational inventories of their own operations, often as the first step towards a certified footprint or a net zero plan.
Buyers usually name the method, and bidders should answer in its terms: the IPCC guidelines for national inventories, the Global Protocol for Community-Scale Greenhouse Gas Inventories for cities, and the GHG Protocol or ISO 14064-1 for organisations. Notices differ most on scope 3, the indirect emissions in supply chains, which can turn a modest assignment into a large one. Check the base year, the scopes and whether verification is included before pricing.
This page tracks open tenders whose own text mentions a greenhouse gas, GHG or emissions inventory. It suits carbon accounting consultancies, environmental engineers and the specialists who support national inventory teams.

Frequently asked
What standards do GHG inventory tenders use?
The IPCC guidelines for national inventories, the Global Protocol for Community-Scale GHG Inventories for cities and regions, and the GHG Protocol Corporate Standard or ISO 14064-1 for organisations.
How big are these contracts?
It varies widely. An organisational inventory for one public body is a small consultancy job; a national inventory improvement programme can run for years. The scope, especially whether scope 3 is included, drives the size.
Is a GHG inventory the same as a carbon footprint?
They overlap. Inventory is the usual term for national, regional and city accounts; carbon footprint is more common for an organisation, product or event. Both appear in notices, so this site has a page for each.
