Biodiversity Net Gain (BNG)

An approach to development, and/or land management which mandates developers to deliver measurable improvements for biodiversity by creating or enhancing habitats in association with development. Biodiversity net gain can be achieved on-site, off-site or through a combination of on-site and off-site measures. In England, a 10% mandatory BNG, will be mandatory for most developments from November 2023.

Biodiversity Unit

A unit of biodiversity, calculated by a qualified ecologist using a biodiversity impact assessment tool, for example Defra’s Biodiversity Metric.

Carbon Credit

A product that can be bought representing either the permanent removal of a tonne of carbon dioxide equivalent (CO2e) from the atmosphere (e.g. through woodland or peatland creation) or the avoidance of one tonne of CO2e being emitted in the first place.

Environmental Market

The system by which trading of ecosystem service credits takes place.

FIRNS (the Facility for Investment Ready Nature in Scotland)

A grant scheme from the Scottish Government and NatureScot to support projects that shape and grow the use of private investment and market-based mechanisms to finance the restoration of Scotland’s nature. FIRNS is a successor to the earlier grant programme, IRNS.

Intermediary

Any organisation that supports the relationship between a seller, a buyer or an investor. It could be by setting standards, the provision of monitoring and verification, or enabling buyers and sellers to find each other.

Investment Readiness

The process of becoming ready to participate in nature finance (which may or may not result in investment).

Natural Capital Accounting

The measuring and quantifying of environmental assets and services, i.e. the habitats and ecosystems that provide social, environmental and economic benefits to people.

Natural Capital Investment

See nature finance. (Note that the term “investment” is often used even if the primary focus is the trading that occurs in nature markets.)

Natural Flood Management

The intentional use of natural features such as vegetation or landform to slow the flow of water from land in order to reduce flood risk.

Nature Finance

The part of green finance that specifically finances or invests in improvements to the natural environment. It is based on the trading that occurs through nature markets.

Nature finance project

A project that is utilising nature finance (including the sale of ecosystem service credits) to deliver improvements to the condition of land, water or nature.

Nature markets

Nature markets are the sale and purchase of ecosystem service credits (ways that the natural environment supports wellbeing and prosperity).

Outcomes payments

Payments made to the investor who has provided upfront investment in a project, with payments dependent on the project meeting pre- agreed environmental outcomes.

Payments for ecosystem services

Schemes through which the beneficiaries, or users, of ecosystem services provide payment to the stewards, or providers of those services.

Peatland Restoration

Peatland Restoration is a term used to describe management measures that aim to restore the original form and function of peatland habitats to favourable conservation status. The principal activity involved in restoration is management of site hydrology which in turn helps to control emissions of greenhouse gases such as carbon dioxide. Depending on the starting point, peatland sites may need drain blocking to rewet them using a variety of techniques including peat dams, plastic piling and bunding, plantation removal, pollution control, Sphagnum transfer and/or control of grazing, burning, water quantity and quality.

Riparian Woodlands

Riparian woodlands are those on the banks of natural bodies of water and particularly rivers.

Revenue

The money generated from business activities. Analogous to gross income.

Stacking

When multiple different ecosystem services produced by the same activities (for example biodiversity and carbon benefits of a new woodland) are sold as separate units in the market.

Supplier

Those producing and selling units of ecosystem services on the land or coastal areas they manage, for example through nature restoration projects or sustainable land management practices.
