Paris Climate Agreement and Carbon Pricing
The effectiveness of carbon pricing in reducing emissions depends to a large extent on its design. There are many considerations for policymakers to consider when designing a carbon pricing system. How much should it cost to emit a tonne of carbon and how should that amount change over time? Who should be responsible for paying the carbon price – fossil fuel producers, consumers or someone in between? Will the carbon pricing system be a source of revenue and how should that revenue be used? Design specifics influence public support for the pricing system, the net cost of carbon emissions, and the system`s impact on environmental justice, all of which can affect the system`s effectiveness in reducing carbon emissions. Given the limited number of countries that have confirmed that they will use international credits and the fact that they are currently not allowed to be satisfied in most national and regional carbon markets, it is currently unclear what the demand for these credits will be. Second, trade could help reduce emissions by making it easier and cheaper for countries to meet their climate targets, while encouraging them to set ever more ambitious targets. This is particularly true for countries considered to be the most vulnerable to the effects of climate change, which have expressed themselves in negotiations on the risks of weakness of Article 6 rules. Another of the most controversial issues for the negotiations is whether Kyoto-era projects should be included in the Article 6(4) trading scheme, as well as the methods of calculating their CO2 savings and the “units” they have already generated. Joint implementation (JI) and the Clean Development Mechanism (CDM) are offset mechanisms under the Kyoto Protocol under which Annex I Parties can participate in low-carbon projects and receive credits in return. Alessandro Vitelli, a freelance carbon market journalist who has been following UN discussions on the issue for 15 years, told Carbon Brief: “Brazil runs banks. He must know that this goes against all financial accounting standards. Hector Pollitt, an economist at the consulting firm Cambridge Econometrics, has already dismissed the idea that carbon pricing is the most cost-effective way to reduce emissions as a “neoclassical fantasy.” About 96 countries` climate commitments – about half of all NDCs – relate to the use of carbon pricing initiatives, according to a World Bank report.
It is suggested that the cost of complying with current NDCs could be reduced by up to 50%, “in principle. with a completely global and frictionless carbon market.” The exact nature of ITMOs and the architecture of the mechanism provided for in Article 6(4) are still under discussion. The operationalisation of the new mechanisms provided for in Article 6 is one of the challenges for carbon pricing to realise its potential for cost-effective decarbonisation and adaptation. There is considerable pressure to move quickly towards consensus, as the Paris Agreement guidelines, including the modalities for operationalising cooperative approaches to emission reductions under Article 6, are to be finalised by December 2018. Proponents argue that a well-designed Article 6 framework could do just that – help countries dramatically scale up their efforts to combat climate change. Similarly, the provision of an `overall reduction in global emissions` (NGC) is an essential requirement of the Article 6(4) mechanism. They consider that it has only been achieved if a fixed proportion of emission credits under Article 6 is set aside and is not used by any Party for its climate objectives. These loans would be cancelled or set aside in favor of the global atmosphere as a whole, rather than for a particular state and its NDC. However, it proved difficult to determine how this would work in practice. The problem would arise if a host country sold Article 6 carbon credits created in a sector that is “outside” the scope of its NDC, rather than falling “into” the promise.
The second approach is to implement an Emissions Trading System (ETS, also known as a cap-and-trade system) for carbon emissions. This system limits carbon emissions to a level set for a group of companies or industrial facilities and then issues emission allowances based on that level. Companies must receive an allowance for every tonne of carbon they want to emit – either directly from the government or by trading with each other. Under an ETS, the price of carbon fluctuates based on market demand for emissions, but the total amount of emissions is known. (This claim is implicitly recognized in the international CDM credit market, where CO2 offsets are currently valued at nearly $0.2/tCO2e.) A little-known and highly technical part of the Paris Agreement could “make or break” the regime – and its goal of avoiding dangerous climate change. These “Article 6” rules for carbon markets and other forms of international cooperation are the last pieces of the Paris regime to be resolved after the rest of its “regulation” was approved at the end of 2018. In recent decades, the United States` global reputation on climate issues has steadily declined. While other countries and nations, such as the EU, have set ambitious climate goals, the United States has continued to fight climate deniers blocking substantial action on climate change.
He rejected adherence to the two most important global climate agreements of the past two decades – the Kyoto Protocol and the Paris Agreement – although he recently joined the latter. Instead of government and policymakers pledging to take meaningful action on climate change, the majority of emission reductions over the past decade have been achieved through changes in fossil fuel consumption and greater efficiency in industry. The exact form of this “robust” accounting under Article 6.2 is the subject of ongoing negotiations, one of the many technical challenges being how to manage trade between NDCs for emissions in a single year, compared to those that set a carbon budget for several years. International Emissions Trading (IEE) is an international ETS established with the aim of enabling Annex I countries to reduce their emissions at the lowest possible cost. However, each country has made policy decisions about other priorities and their national context, and has not necessarily optimized its efforts to reduce emissions based solely on the price of carbon. This heterogeneity of national policies meant that the EIT did not achieve a result with the lowest costs as originally planned. The EIT has also been hampered by a lack of clarity on environmental outcomes, which has impacted its attractiveness to sovereign buyers. The numbers are so large that there could be significant gains, even if the “global total euro” of an internationally harmonised carbon market is not achieved. For example, with smaller pockets of emissions trading in some regions. Other contentious issues included how Article 6(4) can ensure an overall reduction in emissions, how to prevent the supply of credits from far exceeding demand, and how to prevent countries from adopting lower climate targets simply so that they can sell more credit.
If there is no agreement by the end of COP25, the issue will be forwarded to COP26 in Glasgow in December 2020, so the UK will have to push diplomatically to get it through. At the same time, a paper from the Environmental Defense Fund states that emissions trading schemes can “reduce political opposition to more ambitious targets,” citing examples from the EU`s Emissions Trading Scheme, the Regional Greenhouse Gas Initiative and California`s cap-and-trade program. It concludes that climate ambitions with global carbon markets could almost double over the next 15 years compared to current NDCs. “In practice, it is very difficult to establish a clear relationship between the ability to buy cheap carbon credits and a country`s willingness to engage in more climate action.
