Banking Book Taxonomy Alignment Ratio (BTAR)

The Banking Book Taxonomy Alignment Ratio (BTAR) is an EU banking indicator that complements the Green Asset Ratio by also counting exposures the GAR leaves out — notably SMEs and certain non-EU or out-of-scope counterparties.

Base Year Recalculation

Base year recalculation is the adjustment of an organisation's historical base year emissions to keep them comparable after structural changes — such as acquisitions, divestments or methodology updates — so that progress against a target is measured consistently over time.

Carbon Accounting

Baseline (Carbon Projects)

A baseline is the reference scenario of what emissions would have been without a carbon project, against which the project's reductions or removals are measured.

Carbon Markets

Baseline Year

A baseline year is the reference year against which an organisation measures its emissions performance over time and sets reduction targets, chosen for data quality and representativeness and recalculated when the organisation changes structurally.

Carbon Accounting

Battery Passport

A battery passport is the Digital Product Passport for batteries — the first DPP to become mandatory. From 18 February 2027, EV, industrial (over 2 kWh) and light-means-of-transport batteries placed on the EU market must carry a digital passport with their carbon footprint, materials, recycled content and performance data.

Regulation & Compliance

Benchmark (ETS)

A benchmark is the reference emission amount per unit of product or activity in an emissions trading system; free allocation is calculated by multiplying it by activity level, which rewards low-emission (efficient) installations.

Regulation & Compliance

Beneficiary (Responsible Programme)

In the Responsible Programme, the beneficiary is the manufacturer-exporter company that meets the eligibility conditions and is admitted to the programme's support. Being a beneficiary carries obligations as well as support — reporting, evidence and keeping within the programme's rules.

Regulation & Compliance

Biodiversity Credits

A biodiversity credit is a tradable unit representing a measurable, verified gain in biodiversity resulting from a conservation or restoration activity.
