Emissions trading is a market-based approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants. The concept is also known as cap and trade (CAT) or emissions trading scheme (ETS). One prominent example is carbon emission trading for CO2 and other greenhouse gases which is a tool for climate change mitigation. Other schemes include sulfur dioxide and other pollutants.
Environmental finance is a field within finance that employs market-based environmental policy instruments to improve the ecological impact of investment strategies. The primary objective of environmental finance is to regress the negative impacts of climate change through pricing and trading schemes. The field of environmental finance was established in response to the poor management of economic crises by government bodies globally. Environmental finance aims to reallocate a businesses resources to improve the sustainability of investments whilst also retaining profit margins.
The Clean Development Mechanism (CDM) is a United Nations-run carbon offset scheme allowing countries to fund greenhouse gas emissions-reducing projects in other countries and claim the saved emissions as part of their own efforts to meet international emissions targets. It is one of the three Flexible Mechanisms defined in the Kyoto Protocol. The CDM, defined in Article 12 of the Protocol, was intended to meet two objectives: (1) to assist non-Annex I countries achieve sustainable development and reduce their carbon footprints; and (2) to assist Annex I countries in achieving compliance with their emissions reduction commitments.
Carbon offsetting is a carbon trading mechanism that enables entities such as governments or businesses to compensate for (i.e. “offset”) their greenhouse gas emissions by investing in projects that reduce, avoid, or remove emissions elsewhere. When an entity invests in a carbon offsetting program, it receives carbon credits. These "tokens" are then used to account for net climate benefits from one entity to another. A carbon credit or offset credit can be bought or sold after certification by a government or independent certification body. One carbon offset or credit represents a reduction, avoidance or removal of one tonne of carbon dioxide or its carbon dioxide-equivalent (CO2e).
The European Union Emissions Trading System is a carbon emission trading scheme which began in 2005 and is intended to lower greenhouse gas emissions by the European Union countries. Cap and trade schemes limit emissions of specified pollutants over an area and allow companies to trade emissions rights within that area. The EU ETS covers around 45% of the EU's greenhouse gas emissions.
Carbon accounting is a framework of methods to measure and track how much greenhouse gas (GHG) an organization emits. It can also be used to track projects or actions to reduce emissions in sectors such as forestry or renewable energy. Corporations, cities and other groups use these techniques to help limit climate change. Organizations will often set an emissions baseline, create targets for reducing emissions, and track progress towards them. The accounting methods enable them to do this in a more consistent and transparent manner.
Carbon rationing, as a means of reducing CO2 emissions to contain climate change, could take any of several forms. One of them, personal carbon trading, is the generic term for a number of proposed carbon emissions trading schemes under which emissions credits would be allocated to adult individuals on a (broadly) equal per capita basis, within national carbon budgets. Individuals then surrender these credits when buying fuel or electricity. Individuals wanting or needing to emit at a level above that permitted by their initial allocation would be able to purchase additional credits in the personal carbon market from those using less, creating a profit for those individuals who emit at a level below that permitted by their initial allocation.
Aircraft engines produce gases, noise, and particulates from fossil fuel combustion, raising environmental concerns over their global effects and their effects on local air quality. Jet airliners contribute to climate change by emitting carbon dioxide, the best understood greenhouse gas, and, with less scientific understanding, nitrogen oxides, contrails and particulates. Their radiative forcing is estimated at 1.3–1.4 that of CO2 alone, excluding induced cirrus cloud with a very low level of scientific understanding. In 2018, global commercial operations generated 2.4% of all CO2 emissions.
The Global Warming Solutions Act of 2006, or Assembly Bill (AB) 32, is a California state law that fights global warming by establishing a comprehensive program to reduce greenhouse gas emissions from all sources throughout the state. AB32 was co-authored by Assemblymember Fran Pavley and Speaker of the California Assembly Fabian Nunez and signed into law by Governor Arnold Schwarzenegger on September 27, 2006.
The Clean Air Conservancy was a United States non-profit charity devoted to protecting our planet’s clean air and slowing the pace of climate change by actively participating in pollution markets and participating in emissions trading.
Carbon pricing is a method for governments to address climate change, in which a monetary cost is applied to greenhouse gas emissions in order to encourage polluters to reduce the combustion of coal, oil and gas – the main driver of climate change. The method is widely agreed to be an efficient policy for reducing greenhouse gas emissions. Carbon pricing seeks to address the economic problem that emissions of CO2 and other greenhouse gases (GHG) are a negative externality – a detrimental product that is not charged for by any market.
The availability and uptake of green electricity in the United Kingdom has increased in the 21st century. There are a number of suppliers offering green electricity in the United Kingdom. In theory these types of tariffs help to lower carbon dioxide emissions by increasing consumer demand for green electricity and encouraging more renewable energy plant to be built. Since Ofgem's 2014 regulations there are now set criteria defining what can be classified as a green source product. As well as holding sufficient guarantee of origin certificates to cover the electricity sold to consumers, suppliers are also required to show additionality by contributing to wider environmental and low carbon funds.
The carboNZero programme and CEMARS programme are the world’s first internationally accredited greenhouse gas (GHG) certification schemes under ISO 14065. They provide tools for organisations, products, services and events to measure and reduce their greenhouse gas emissions, and optionally offset it. The programmes are owned and operated by Toitū Envirocare - Enviro-Mark Solutions Limited, a wholly owned subsidiary of Landcare Research.
Carbon emission trading (also called carbon market, emission trading scheme (ETS) or cap and trade) is a type of emission trading scheme designed for carbon dioxide (CO2) and other greenhouse gases (GHG). It is a form of carbon pricing. Its purpose is to limit climate change by creating a market with limited allowances for emissions. This can reduce the competitiveness of fossil fuels, and instead accelerate investments into renewable energy, such as wind power and solar power. Fossil fuels are the main driver for climate change. They account for 89% of all CO2 emissions and 68% of all GHG emissions.
ecosecurities is a company specialized in carbon markets and greenhouse gas (GHG) mitigation projects worldwide. ecosecurities specializes in sourcing, developing and financing projects on renewable energy, energy efficiency, forestry and waste management with a positive environmental impact.
The Chinese national carbon trading scheme is an intensity-based trading system for carbon dioxide emissions by China, which started operating in 2021. This emission trading scheme (ETS) creates a carbon market where emitters can buy and sell emission credits. The scheme will allow carbon emitters to reduce emissions or purchase emission allowances from other emitters. Through this scheme, China will limit emissions while allowing economic freedom for emitters. China is the largest emitter of greenhouse gases (GHG) and many major Chinese cities have severe air pollution. The scheme is run by the Ministry of Ecology and Environment, which eventually plans to limit emissions from six of China's top carbon dioxide emitting industries. In 2021 it started with its power plants, and covers 40% of China's emissions, which is 15% of world emissions. China was able to gain experience in drafting and implementation of an ETS plan from the United Nations Framework Convention on Climate Change (UNFCCC), where China was part of the Clean Development Mechanism (CDM). China's national ETS is the largest of its kind, and will help China achieve its Nationally Determined Contribution (NDC) to the Paris Agreement. In July 2021, permits were being handed out for free rather than auctioned, and the market price per tonne of CO2e was around RMB 50, far less than the EU ETS and the UK ETS.
China Beijing Environmental Exchange (CBEEX) is a corporate domestic and international environmental equity public trading platform initiated by the China Beijing Equity Exchange (CBEX) and authorized by the Beijing municipal government.
