Planning & management

Governance structures and team members’ roles and skills are reviewed in the early stages of inventory system development. Data supply agreements are specified and agreed to ensure high quality regular data inputs.

Stakeholder engagement

Meetings are held with interested parties to agree on delivery of inventory outputs and methodology improvements.  Stakeholder groups usually include Government departments, data suppliers and other data users such as air pollution modellers.

Inventory compilation

Calculations are undertaken to update the annual inventory for historical years and for a new year of the timeseries. All calculations are subject to thorough quality checks and comparisons with previous datasets.

Reporting

As well as reporting directly to government clients, the inventory data are often delivered to international organisations (UNFCCC, UNECE, EC) according to formal reporting requirements. Clear documentation of methodologies is provided alongside international submissions, specifying methods, assumptions and reasons for changes.

Review

Each year Kyoto Protocol signatory countries have their greenhouse gas inventories reviewed by a panel of experts. Aether provides experts for these review panels and is also able to support Governments in responding to reviewer questions. A similar process is also in place to review air quality pollutant inventories.

Projections

Estimates of the way emissions are expected to change in the future are also required under international agreements. This requires separate estimates of emissions under a ‘Business as usual’ scenario and of the impacts of new policy measures to reduce emissions.
