The Pennsylvania Commonwealth Court granted Pennsylvania State Senators’ (Senate) request for a preliminary injunction blocking the Pennsylvania Department of Environmental Protection from implementing and enforcing regulations providing for Pennsylvania’s participation in the Regional Greenhouse Gas Initiative (RGGI). RGGI participating states establish carbon dioxide budgets for power plants, and covered sources must acquire allowances to cover their emissions. RGGI, Inc. conducts quarterly auctions for the allowances, and proceeds go to participating states. The court found that the Senate had demonstrated irreparable harm per se by raising a substantial legal question as to whether the regulations constituted a tax requiring legislative approval as opposed to a regulatory fee. The court further found that implementation and enforcement of invalid regulations would cause greater harm even if implementation of the regulations would result in “immediate reduction” of carbon dioxide emissions from covered sources. In addition, the court found that the preliminary injunction would restore the status quo and that the Senate had showed a clear right to relief by raising substantial legal questions about separation of powers issues related to the Regulatory Review Act, as well as concerning whether the allowance auction proceeds were an unconstitutional tax. The court found, however, that the Senate did not raise substantial legal questions regarding whether the regulations exceeded authority granted by the Air Pollution Control Act, whether the regulations constituted an interstate compact or agreement in violation of the Pennsylvania Constitution, or whether the administrative process through which the regulations were adopted was lawful.

Proceeding concerning the publication of Pennsylvania regulations to implement the State's participation in the Regional Greenhouse Gas Initiative cap-and-trade program for carbon dioxide emissions from power plants.

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

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.

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.

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 financial institution that manages a country's currency and can promote climate-related initiatives through green monetary policy and other means.

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

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

Actions to reduce emissions in energy generation and supply.

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.

Social inclusion is the process of improving the terms on which individuals and groups take part in society—improving the ability, opportunity, and dignity of those disadvantaged on the basis of their identity.

Production of electricity and heat from solar irradiation.

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.

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

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

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

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

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

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.
