Green financing

What it means

Green financing is an umbrella term for financial instruments tied to projects or activities with a positive effect on the climate and environment. It covers green loans and mortgages, green bonds, sustainability-linked loans, green leasing and grants or subsidised programmes from public sources.

Typical projects financed include solar and other renewable energy, insulation and renovation of buildings, energy-efficient technology, electric mobility, the circular economy and organic farming. With a green loan the money must go to a specific project; with a sustainability-linked loan the interest rate varies depending on whether the company meets agreed indicators.

The framework for judging what is genuinely green is the EU taxonomy, which sets criteria for environmentally sustainable activities. Banks and investors must report what share of their portfolios such activities represent, so they increasingly ask clients for emissions data and ESG information.

How it works in practice

For small and medium-sized businesses, green financing is often available through bank products with preferential rates for solar panels, insulation or electric vehicles, programmes supported by EU and state funds, and subsidised leasing. Benefits can include a lower margin, a longer term or combination with a grant.

The condition is usually evidence of purpose and impact: an energy audit, project documentation, estimated energy or emission savings and proof of results after completion. For sustainability-linked loans, indicators are reported and verified regularly. The company should set up data collection before signing.

Green financing should be compared with an ordinary loan on total cost, including verification and administration fees. It often pays off not only on price but because the investment cuts energy costs and prepares the company for customer and regulatory requirements.

What to watch out for

Beware of greenwashing. If a company claims a green purpose but uses the money otherwise or overstates the benefit, it risks not only its reputation but also breaching loan terms and, for bonds, regulatory penalties. Claims of impact must be backed by measurement and documentation.

Green financing terms may contain obligations for years ahead, such as maintaining a building certificate, achieving emission reductions or reporting annually. Failure can mean a higher rate or having to repay the benefit. Before signing, assess whether the targets are realistic.
