Question 1

What is green finance, and what is a green bond?

Accepted Answer

Finance directed towards environmentally beneficial activity — and a **green bond** is its most visible instrument: a normal bond whose proceeds are earmarked for qualifying projects.

**How a green bond works.** An issuer — a government, bank or company — borrows in the usual way, promising the same repayment and interest as any other bond of the same credit quality. The difference is a **commitment about use of proceeds**: the money funds renewable energy, efficient buildings, clean transport, water infrastructure or similar, with reporting on where it went.

**The crucial and frequently missed point.** A green bond is usually backed by the **issuer's whole balance sheet**, not by the projects. It does not ring-fence risk, and defaulting on the green commitment generally does not trigger a default on the bond itself — enforcement rests on reputation rather than on contract.

**Related instruments:**

**Sustainability-linked bonds**, where the interest rate changes if the issuer misses stated targets. **This puts a financial penalty behind the promise**, and is stronger in principle — with criticism that many targets are unambitious or would have been met anyway.

**Transition finance**, for high-emitting sectors reducing emissions rather than already-clean activity. Contested, because it directs capital to fossil-dependent industries, and defensible because those are where the emissions are.

**Green loans and sustainability-linked loans**, the private equivalents.

**The additionality question, which is the heart of the criticism.** If a company would have built the wind farm anyway, labelling the bond green changes nothing about the world — it relabels existing activity. **Demonstrating that finance caused something to happen is genuinely hard**, and much reporting does not attempt it.

**The other criticisms:** inconsistent definitions of what qualifies; limited external verification in some markets; the "greenium" — a slightly lower borrowing cost — being small enough that it barely changes behaviour; and issuers using green bonds while expanding fossil activity elsewhere.

**What is improving:** official taxonomies defining qualifying activity, mandatory climate-related disclosure in several jurisdictions, and regulatory attention to fund labelling after widespread mislabelling.

Question 2

What is greenwashing and how do I spot it?

Accepted Answer

Greenwashing is presenting something as more environmentally responsible than it is. It ranges from outright false claims to technically true statements arranged to mislead, and the second is far

Question 3

How to create a green building?

Accepted Answer

Creating a green building involves sustainable design, energy efficiency, water conservation, and using eco-friendly materials. These practices enhance environmental quality and reduce costs.

Question 4

What are ecosystem services?

Accepted Answer

The benefits people obtain from ecosystems — a framework for making nature's contribution visible in decisions that would otherwise treat it as worth nothing. The four categories, from the Millennium

Question 5

What is a renewable energy certificate, and does buying green electricity work?

Accepted Answer

A certificate proving that a unit of electricity was generated from a renewable source — and whether buying one changes anything depends on a concept called additionality, which is where most green

Question 6

What is the social cost of carbon?

Accepted Answer

An estimate, in money, of the damage caused by emitting one additional tonne of carbon dioxide — used to put climate effects into cost-benefit analysis of policies and projects. Why it exists.

Question 7

What does "net zero" actually mean?

Accepted Answer

Net zero means the total greenhouse gases added to the atmosphere are balanced by an equivalent amount removed, so the net addition is zero. It is deliberately different from absolute zero, which
