In this paper, a multilayer recurrence network is introduced to examine the information linkage between carbon and energy markets. We first construct a multilayer recurrence network of energy and carbon markets, and we define the information linkage coefficient to measure the linkage relationship between the network layers based on the network microstructure. To measure the mutual leading relationship between carbon and energy markets, we construct a time-delay multilayer recurrence network and introduce the time-delay information linkage coefficient to measure the intersystem interaction. The carbon and energy prices, including West Texas Intermediate crude oil, coal, natural gas, and gasoline, from February 22, 2011, to April 1, 2019, are selected as sample data for empirical analysis. The results show that the linkage relationship between oil, coal, natural gas, and carbon prices presents a U-shaped trend in the second, transitional, and third phases of the European Union carbon market, while the linkage trend of gasoline and carbon prices continues to rise. The mutual leading relationship between energy and carbon prices changes in different stages, and carbon price plays a leading role at the present stage.

Since the creation of the European Union Emissions Trading Scheme (EU ETS) in 2005, a burgeoning academic literature has emerged to identify the factors that shape the price of carbon, where one European Union Allowance is equal to one ton of CO2-equivalent emitted in the atmosphere. Thus, there is a need for an updated and thorough literature review on the state-of-the-art on topic that this paper aims to fulfill. Namely, the author considers the main econometric studies that have been recently published in the academic literature, which feature the influence of the following determinants to explain the variation of the price of carbon: institutional decisions; energy prices and weather events; macroeconomic and financial market shocks. The paper concludes with some directions for future research in this area.

Abstract The issue of energy prices presents an extremely topical subject with a major impact on human society. Energy demand is constantly increasing and most regions of the world are facing serious difficulties in ensuring sufficient energy supplies. However, not only global events affect energy prices in the particular country. National energy markets are highly specific and some local factors may also prove significant. In our contribution we focus on the Slovak Republic and try to analyze the major political and economic factors affecting the final price of energy, particularly of gas and electricity. We pay attention to the period from the accession of the country to the European Union in 2004 until 2011 characterised by ‘third liberalisation package’ that is associated with a wide range of major changes. Largely monopolized energy market has been gradually opening up to competition and the countries with regulated prices have been facing the increasing pressure to let the free market decide. Progressive liberalisation of energy markets enables consumers to use the energy services offered by various private companies. This new element operating in the energy sector is largely reflected in final energy prices. Thus, the main goal of this study is to highlight the price disparities between different energy commodities in European Union member states since we are at present witnesses to of significant regional disparities in energy prices. We try to analyze current energy prices with respect to GDP (regarding purchasing power parity as well) to ensure that resulting comparison would reflect the financial potential of the population. Demonstrating the effects of the economic crisis on energy prices in different countries will be another important aspect of this contribution.

Natural gas marketing has considerably evolved since the early 1990s, when a set of liberalizing rules were passed in both the United States and the European Union that eliminated state-driven regulations in favor of open energy markets. These new rules changed many things in the business of energetics, and therefore new research opportunities arose. Econometric studies about natural gas emerged as an important area of study since natural gas may now be sold and traded in a number of stock markets, each one responding to potentially different behavioral drives. In this work, we present a method to differentiate sets of time series based on a regression model relating price, consumption, supply, and other factors. Our objective is to develop a method to classify different areas, regions, or states into groups or classes that share similar regression parameters. Once obtained, these groups may be used to make assumptions about corresponding natural gas prices in further studies.

Abstract The European Union (EU) Emissions Trading System (ETS) has implicitly made it more expensive to burn coal relative to natural gas because coal has a higher carbon content. Therefore, it is important to understand how much plants reduce their coal usage in response to higher coal prices to assess the effectiveness of the ETS in reducing carbon emissions. We analyze a novel panel of coal-burning large combustion plants from a subsample of eight EU countries and found that, holding constant the natural gas price, a 1% increase in the coal price results in a 0.36% decrease in coal consumption. At current ETS prices, this implies that the average large combustion plant in our sample EU countries is burning 7% less coal than it would be absent in the ETS. This suggests that the ETS has significantly reduced carbon emissions from coal-fired plants for the eight countries represented in our sample.

This paper studies the volatility spillover and dynamic correlation between EU emission allowance (EUA) prices and energy prices by considering three energy commodities, including oil, gas, and coal. The asymmetric BEKK model is employed for multi-phase analysis of EU ETS, yet only a little empirical evidence backing up the existence of volatility spillover between EU ETS and energy markets, i.e., the establishments of the EU ETS may not effectively limitation and influence energy markets. The time-varying conditional correlation between EUA and each of energy prices is analyzed. The dynamic correlation shows there is a relatively stable, positive correlation between the EUA and Brent oil, natural gas. However, modeling the dynamics correlation also suggests that the correlation between the EUA and the natural gas, coal became weaker and more volatile since second and third phases, especially after the Global Financial Crisis in 2008, which may indicate that the demand reduction in emission allowances caused by the economic slowdown far exceeds the reduction in the annual restraint of EU ETS.

Carbon price is a key variable in management and risk decisions in activities related to the burning of fossil fuels. Different major players in this market, such as polluters, regulators and financial actors, have different time horizons. We use innovative multivariate wavelet analysis tools, including partial wavelet coherence and partial wavelet gain, to study the link between carbon prices and final energy prices in the time and frequency dimensions in California's carbon market, officially known as the California cap-and-trade programme. We find that gasoline prices lead an anti-phase relation with carbon prices. This result is very stable at lower frequencies (close to 1-year period cycles), and it is also present before mid-2015 in the 20–34 weeks frequency band. Regarding electricity, we find that at about a 1-year period, a rise in carbon prices is reflected in higher electricity prices. We conclude that the first 5 years of compliance of the California cap-and-trade programme show that emissions trading is a significant measure for climate change mitigation, with visible rising carbon prices. The quantitative financial analytics we present supports the recent decision to extend the current market to 2030 without the need for complementary carbon pricing schemes.This article is part of the theme issue ‘Redundancy rules: the continuous wavelet transform comes of age’.

Since carbon price volatility is critical to the risk management of the CO2 emissions trading market, research has focused on energy prices and macroeconomic drivers which cause changes in carbon prices and make the carbon market more volatile than other markets. However, they have ignored whether the impact of carbon price determinants changes when the carbon price is at different levels. To fill this gap, this paper applies a semiparametric quantile regression model to explore the effects of energy prices and macroeconomic drivers on carbon prices at different quantiles. The model combines the advantages of parameter estimation, nonparametric estimation and quantile regression to describe the nonlinear relationship between carbon price and its fundamentals, which do not need to make any assumptions about the random error. Carbon prices are high–tailed and exhibit higher kurtosis, the traditional models which tend to assume that data are normally distributed can’t perform well. Furthermore, the semiparametric model doesn’t need to assume that the data are normally distributed. Therefore, the semiparametric model can effectively model the data. Some new evidence from China’s emission trading scheme (ETS) pilots shows that energy prices and macroeconomic drivers have different effects on carbon prices at high or low quantiles. First, the negative impact of coal prices on carbon prices was greater at the lower quantile of carbon prices in the Shenzhen ETS pilot. However, the effects of coal prices were positive in the Beijing ETS pilot, which may be attributed to great demand for coal. Second, oil prices had greater negative effects on carbon prices at higher quantiles in Beijing and Hubei ETS pilots. This can be attributed to the fact that businesses use less oil when carbon prices are high. For the Shenzhen ETS pilot, the effects of oil prices were positive. Third, natural gas prices have a stronger effect on carbon prices as quantiles increased in the Beijing and Hubei ETS pilots. Lastly, the effects of macroeconomic drivers on carbon prices at low quantiles were stronger in the Shenzhen ETS pilots and higher at the medium quantiles in Beijing and Hubei ETS pilots. These findings suggest that the impact of determinants on the carbon prices at different levels is not constant. Ignoring this issue will lead to a missed warning about the risks of the carbon market. This study will be of positive significance for China’s emission trading scheme (ETS) pilots, in order to accurately monitor the effects of carbon prices determinants and effectively avoid carbon market risks.

Natural gas is almost certain to be the fastest-growing fossil fuel in the global energy mix for decades to come, comprising 28% of the global energy mix by 2050. Together with renewables, natural gas will likely fuel 60% of global electricity production, be it as pipeline gas, liquefied natural gas (LNG), or blue hydrogen. These are among the forecasts that appear in the 2020 edition of the GECF (Gas Exporting Countries Forum) Global Gas Outlook 2050 released in February 2021 and providing short-, medium-, and long-term energy projections based on assumptions regarding macroeconomic conditions, energy prices, and policies. The report is updated yearly and is the flagship publication of the organization, which represents countries that control 71% of global gas reserves. It is unique in that it focuses exclusively on the global gas industry, which today is providing for 23% of global energy needs. Headquartered in Doha, Qatar, the GECF is an intergovernmental organization comprising 11 member countries and nine observer states, established in 2001 by Russia and Iran. Moscow and Tehran had hoped that GECF would eventually morph into a “Gas OPEC” but that never happened. The organization’s analyses and forecasts do, however, present a worthwhile snapshot of how the world’s largest gas producers see the industry. Member states in GECF include Algeria, Bolivia, Egypt, Equatorial Guinea, Iran, Libya, Nigeria, Qatar, Russia, Trinidad and Tobago, and Venezuela. Observer countries are Angola, Azerbaijan, Iraq, Kazakhstan, Malaysia, Norway, Oman, Peru, and the UAE. Unconventional Gas To Play Growing Role In its report, the GECF noted that unconventional resources will be playing a growing role in the market and that gas producers will need to emphasize unconventional projects to satisfy growing demand, as well as to invest heavily into exploration to identify and tap into new gas reserves and develop greenfield projects. “It is also important to highlight the increasing interest in hydrogen as a lever to support the deep decarbonization of the world’s economies,” Yury P. Sentyurin, GECF’s Secretary General, wrote in his introduction to the annual outlook. In mentioning hydrogen, Sentyurin is speaking about “blue hydrogen” which is produced from natural gas, and which, when combined with CCUS (carbon capture, utilization, storage) can marry commercial and environmental interests, further positioning natural gas as a transition fuel to bridge the gap between fossil fuels and renewable sources of energy. Blue hydrogen is in fact expected to satisfy half of the hydrogen demand projected worldwide by 2050, Sentyurin points out. Policies being set by countries in the European Union have focused more on costly “green hydrogen” produced from renewable sources; but not in the policies of other nations in regions of the world where growth in energy demand is expected to be the highest. Growth in European energy demand is largely flat.

The COVID-19 pandemic storm has struck the world economies and energy markets with extreme strength. The goal of our study is to assess how the pandemic has influenced oil and gas prices, using energy market reactions in the United States and Japan. To investigate the impact of the COVID-19 cases on the crude oil and natural gas markets, we applied the Auto-Regressive Distributive Lag (ARDL) approach to the number of the US and Japanese COVID-19 cases and energy prices. Our study period is from 21 January 2020 to 2 June 2020, and uses the latest data available at the time of model calibration and captures the so-called “first pandemic wave”. In the US, the COVID-19 pandemic had a statistically negative impact on the crude oil price while it positively affected the gas price. In Japan, this negative impact was only apparent in the crude oil market with a two-day lag. Possible explanations of the results may include differences in pandemic development in the US and Japan, and the diverse roles both countries have in energy markets.

Since 2007, the use of natural gas in China depends on the import, and with an increase in natural gas consumption, gas imports are also constantly growing. In 2018, Chinas natural gas imports approached 100 billion cubic meters, which is 70 times more than in 2006. In recent years, increasing attention has been paid to the use of natural gas in China. Turkmenistan is Chinas main source of pipeline gas imports, and China is Turkmenistans largest exporter of natural gas. In the framework of the traditional model of oil and gas cooperation, China and Turkmenistan are facing such problems as the uniform content of cooperation, lack of close ties in the field of multilateral cooperation and slow progress in the development of the entire industrial chain. Cooperation between China and Central Asia in the field of oil and gas is increasingly affecting the nerves of other countries, except the five countries of Central Asia, but including Russia, Afghanistan, Pakistan, India, Iran and other countries of the Middle East, Japan, South Korea, etc. and even the European Union and the USA. Despite the favorable trading environment for both parties, there are also problems in the domestic market of Turkmenistan and the risks of international competition.
