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.

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

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

Slow onset events evolve gradually from incremental changes over many years or from increased frequency or intensity of recurring events. As defined in the Cancun Adaptation Framework (2010), slow onset events include risks and impacts from rising temperatures, desertification, biodiversity loss, land and forest degradation, glacial retreat, ocean acidification, sea level rise, and salinization.

Risks to the ecosystem health of the marine environment, including ocean warming, ocean acidification, and ocean deoxygenation, harming biodiversity, species health, ecosystem services, and coastal community livelihoods.

Any compulsory, unrequited payment to the government levied on corporations or individuals. This can be for environmental reasons, such as introducing a Carbon tax to set a price that emitters must pay for the greenhouse gases they emit.

Activities that involve planning, designing and building infrastructure, residential, and commercial structures.

Climate change impacts our society by disrupting the natural, economic and social systems we depend on. Physical hazards and underlying vulnerabilities can lead to increased resource competition for food and water, which can heighten the risk of conflict.

Activities of businesses and institutions that provide financial services and products to individuals and organisations.

The activities of industries involved in the production, distribution, and sale of energy, including electricity, gas, and renewables.

Oil is a combustible liquid fossil fuel composed mainly of hydrocarbons, occurring as crude oil and refined into petroleum products such as petrol, diesel and kerosene.

The release of heat-trapping gases, primarily from human activities such as burning fossil fuels, agriculture and industry.

Extreme weather refers to events where a weather variable exceeds (or falls below) a threshold. Meaning it is significantly different from the average or usual weather pattern.

Fossil gas, commonly known as natural gas, is a fossil fuel consisting chiefly of methane with smaller amounts of other hydrocarbons and trace gases, found in underground deposits.

Terrestrial means "of the earth" and relates to the risks to ecological system that includes all living organisms and their interactions within land-based environments, such as forests, grasslands, and deserts.

Activities involving the catching, processing, and selling of fish for food, recreation, and industry.

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.

A commitment to balance GHG emissions with removal by a certain point in time, effectively reducing the net emissions to zero

Activities of industries that extract natural resources, such as mining, oil, and gas, for commercial use.

Financial support to help individuals manage the effects of unexpected events, securing their livelihoods and increasing the resilience of people and businesses to the changing climate. It’s especially vital in developing regions where everyday risks, climate-related weather extremes, or crop failures can push people into poverty. Without insurance, people may have to resort to selling assets or cutting consumption to cope with losses.

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

The cryosphere is the frozen part of the Earth—it includes sea ice, glaciers, snow, and ice sheets. It helps regulate the climate and weather by reflecting sunlight. Rising temperatures are causing melting, leading to sea ice loss, glacier collapse, and glacier landslides and avalanches. This threatens the livelihoods of around 700 million people who rely on the cryosphere for food, water security, and cultural practices.

Social and cultural groups that share collective ancestral ties to the lands and natural resources where they live, occupy or from which they have been displaced
