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.

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.

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

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

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.

Activities that provide lodging, food, and entertainment services to guests, including hotels, restaurants, and resorts.

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.

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

Work that is productive and delivers a fair income, security in the workplace and social protection for all, better prospects for personal development and social integration, freedom for people to express their concerns, organize and participate in the decisions that affect their lives and equality of opportunity.

Activities that relate to the production of goods and services from forests.

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.

Actions or measures to adapt freshwater systems to climate change.

This sector involves managing waste treatment, sanitation, pollution control and environmental cleanup.

People who are less able to respond to the effects of climate change due to having limited financial or physical assets

Electrical energy generated from mechanical devices driven by flowing fresh water.

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

Production of electricity and heat from solar irradiation.

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.

Hot temperature extremes are daily maximum temperatures  that were exceeded on average once in a decade or once in 50 years, and includes heatwaves.

People whose health, both mental and physical, makes them more vulnerable to the effects of climate change

Codes and standards are regulatory instruments that specify minimum standards to protect health and safety. This ranges from performance standards, which prescribe outcomes while allowing flexibility to achieve compliance, to the more prescriptive approach of technology-specific standards.

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

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.

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

This sector involves the wholesale and retail selling of goods.

Tradable permits are market-based tools that grant permission for specific activities, frequently used to regulate emissions. These permits can be issued within a trading system to manage environmental impacts.

People with different national or cultural traditions from the dominant population

Climate change can have a range of impacts on technological system. Extreme weather events can cause infrastructure failures like power outages or damage to roads and bridges, as well as the impacts from waste following natural disasters. Human activities also cause technological impacts, such as the risks posed by oil spillage and leaks.

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.
