An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.

The management and allocation of funds, assets and investments to meet various objectives

A long-lived, colourless gas, chiefly emitted from fossil fuel combustion, deforestation and cement production.

Any substance with chemical properties that can cause physical harm to people or damage the environment, including ammonia, carbon monoxide, phosphine, chlorine, arsenic, cadmium, mercury, pesticides, dioxins, microplastics, benzene, asbestos, aflatoxins, fluoride, methanol, and toxins from marine sources.

Actions or measures to adapt terrestrial systems to climate change.

This sector includes firms and individuals offering specialised expertise in fields such as law, accounting, consulting, science and engineering.

Conditions that enhance the feasibility of adaptation options. Enabling conditions include finance, technological innovation, strengthening policy instruments, institutional capacity, multi-level governance and changes in human behaviour and lifestyles.

Air pollution involves harmful contaminants in the air, affecting both indoor and outdoor environments. It can lead to health issues like respiratory diseases and heart problems, and climate impacts such as global warming. Pollutants can damage plants, trees, habitats, and water bodies like rivers and lakes.

Actions or measures to adapt freshwater, coastal and marine systems to climate change.

Actions or measures to adapt freshwater systems to climate change.

A potent, short-lived greehouse gas, largely released from livestock, fossil fuel extraction and waste management.

This sector involves activities to move goods and people, alongside the storage of products.

Geohazards are adverse geological phenomenon's that are capable of causing widespread damage or loss to property, life and the environment, such as earthquakes, volcano eruptions and tsunamis. Climate change can increase the frequency and severity of some geohazards, such as landslides, and soil erosion.
