The RE 2020 is the new energy and environmental regulations for all new construction. It introduces environmental performance in new construction via life cycle analysis.
The RE2020 applies in several stages:
<ul>
<li>initially, it concerns: individual houses and collective housing;</li>
<li>secondly, it concerns: primary and secondary education offices and buildings;</li>
<li>in a third step, it concerns specific tertiary buildings: hotels, shops, gymnasiums.</li>
</ul>
RE is broken down broadly into three areas: energy; comfort and carbon. ‘Energy’ relates mainly to the energy consumption required while the building is in operation, which is now based on CO2 emissions rather than kilowatt hours. This is referred to as ‘energy carbon impact’ in RE2020. ‘Comfort’ refers to the amount of discomfort permitted in hot weather. The regulations limit the maximum indoor temperature a building can reach during five consecutive hot summer days. ‘Carbon’ measurements are the climate-change impact of the construction itself, including the building materials and the construction process. This is known as the construction carbon impact, which will reduce significantly over the years, by 2025, 2028 and 2031.

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.

Justice is the ethical and political framework that addresses fairness, including issues of responsibility, rights, and structural inequity.

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

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.

A ban is a legal action that prevents the sale or supply of a product or service, or that recalls a product from the market. Examples are bans on SF6, greenwashing, fossil fuel advertisement or single-use plastics.

A target to reduce the prevalence of a greenhouse gas over a specific time frame

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

Either money or something of monetary value is transferred between two or more organisations, people or countries.

Actions or measures to adapt freshwater systems to climate change.

Actions to adapt human health, healthcare systems and well-being to climate change.

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

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

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

Replacing technologies that burn fossil fuels directly with alternatives powered by electricity.

Actions to reduce emissions in energy generation and supply.

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.

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.

Production of electricity and heat from solar irradiation.

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.

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.

Jobs that contribute to preserving or restoring the environment. We include jobs which require a high amount of green skills or which spend much of their time on green activities, as well as jobs transforming polluting industries.

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

The activities of industries that transforms raw materials into finished goods through industrial processes.

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

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

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

This sector involves the wholesale and retail selling of goods.

This sector creates and distributes information and entertainment through television, radio, print, and digital platforms.

This sector provides communication services, software development, and IT solutions.

Activities of government agencies and institutions that provide public services, enforce laws and manage public resources.

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

This sector involves the distribution, treatment, and conservation of water resources.

the fair distribution of risks and opportunities of climate change and the transition to a regenerative economy, cognisant in particular of disproportionate impacts on vulnerable communities and the working class

Procedural justice means ensuring that decision making is safe, transparent and inclusive, emphasizing the agency and influence of vulnerable groups and those most impacted.

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.
