Climate Policy and Regulation

**Abatement Cost #

** The cost of reducing greenhouse gas (GHG) emissions through various strategies and technologies. Abatement costs can vary depending on the specific GHG being targeted, the sector in which reductions are being made, and the level of reductions being sought.

**Adaptation #

** The process of adjusting to the impacts of climate change, including changes in weather patterns, sea level rise, and other environmental changes. Adaptation measures can include building sea walls to protect against sea level rise, developing drought-resistant crops, and improving infrastructure to withstand extreme weather events.

**Carbon Capture and Storage (CCS) #

** A technology that captures carbon dioxide (CO2) emissions from industrial processes or power plants, and then stores the CO2 underground in rock formations or other geological structures. CCS is seen as a key technology for reducing CO2 emissions in sectors that are difficult to decarbonize, such as heavy industry and aviation.

**Carbon Footprint #

** The total amount of greenhouse gas emissions associated with a particular activity, product, or organization. Carbon footprints can be measured in terms of CO2 equivalent emissions, and can be used to identify areas where emissions can be reduced.

**Carbon Pricing #

** A policy approach that involves setting a price on carbon emissions, either through a carbon tax or a cap-and-trade system. Carbon pricing provides an economic incentive for businesses and individuals to reduce their carbon footprint, and can be an effective way to drive emissions reductions across entire economies.

**Cap #

and-Trade:** A type of carbon pricing system in which a cap is set on the total amount of greenhouse gas emissions that can be emitted by a particular sector or economy. Permits to emit CO2 are then distributed or auctioned off, and companies can trade permits with each other. This creates a market-based system that encourages companies to reduce their emissions in order to avoid having to purchase additional permits.

**Climate Change #

** A long-term change in the average weather patterns that have come to define Earth's local and regional climates. Climate change is primarily caused by human activities, such as the burning of fossil fuels and deforestation, which release greenhouse gases into the atmosphere and trap heat.

**Climate Financing #

** The provision of financial resources to support climate change mitigation and adaptation efforts, particularly in developing countries. Climate financing can come from a variety of sources, including governments, multilateral development banks, and private sector investors.

**Climate Policy #

** The set of laws, regulations, and strategies that governments and organizations use to address climate change. Climate policy can include measures to reduce greenhouse gas emissions, promote renewable energy, adapt to the impacts of climate change, and finance climate change mitigation and adaptation efforts.

**Decarbonization #

** The process of reducing the amount of greenhouse gas emissions associated with a particular activity, product, or sector. Decarbonization can be achieved through a variety of strategies, including energy efficiency measures, the use of renewable energy sources, and carbon capture and storage technologies.

**Emissions Reduction Targets #

** The specific levels of greenhouse gas emissions reductions that governments or organizations aim to achieve over a certain time period. Emissions reduction targets can be set at the national, state, or local level, and can be legally binding or voluntary.

**Energy Efficiency #

** The use of less energy to perform the same task or function. Energy efficiency measures can include improving insulation in buildings, using more energy-efficient appliances, and implementing smart grid technologies.

**Fossil Fuels #

** Fuels derived from the ancient remains of plants and animals, such as coal, oil, and natural gas. Fossil fuels are the largest source of greenhouse gas emissions, and their use is a major contributor to climate change.

**Green Economy #

** An economy that prioritizes sustainable development, the efficient use of resources, and the reduction of environmental impacts. A green economy typically involves the promotion of renewable energy, energy efficiency, and sustainable transportation, as well as the protection of natural resources and ecosystems.

**Greenhouse Gases (GHGs) #

** Gases in the Earth's atmosphere that trap heat and contribute to climate change. The most common GHGs are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

**Mitigation #

** The process of reducing greenhouse gas emissions in order to slow the pace of climate change. Mitigation measures can include reducing energy use, increasing energy efficiency, promoting renewable energy, and implementing carbon capture and storage technologies.

**Renewable Energy #

** Energy derived from sources that are replenished naturally, such as wind, solar, hydro, and geothermal power. Renewable energy sources are considered to be more sustainable and less harmful to the environment than fossil fuels.

**Resilience #

** The ability of a system, community, or society to withstand and recover from shocks and stresses, including those related to climate change. Resilience measures can include building sea walls, improving infrastructure, and developing early warning systems.

**Sustainability #

** The use of resources in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainability involves balancing economic, social, and environmental considerations in decision-making.

**Transitional Risk #

** The risk associated with the transition from a high-carbon to a low-carbon economy. Transitional risk can include the impact of new regulations, technological changes, and shifts in market demand on businesses and investors.

**Voluntary Carbon Market #

** A market for the trading of voluntary carbon credits, which are used by companies and individuals to offset their carbon emissions. Voluntary carbon credits are typically generated through projects that reduce or remove greenhouse gas emissions, such as reforestation or renewable energy projects.

**Zero #

Carbon Economy:** An economy in which greenhouse gas emissions have been reduced to zero, or near-zero, levels. A zero-carbon economy can be achieved through a combination of decarbonization measures, such as the use of renewable energy, energy efficiency, and carbon capture and storage technologies.
