Abstract A number of intergovernmental agreements, the most important of which are the Paris Agreement (UN Framework Convention on Climate Change) and the European Green Deal, provide for resource efficiency and the reduction of greenhouse gas and particulate matter (PM2.5, PM10) emissions to 2030 (short-term program to reduce emissions by at least 55 %) and to achieve emissions-neutral production, transport and household activities by 2050. The European Union (EU) has taken the lead in developing and implementing climate change mitigation policies for both industrial and private residential homes in the world through a green course. As an EU country, Latvia has joined both the EU-level climate policy and developed its policy, regulatory documents and action plans for 2021–2030 (Latvia’s National Energy and Climate Plan for 2021–2030), climate policy, including a policy aimed at significantly reducing GHG emissions and increasing efficiency in the household sector. Achieving these climate policy goals requires both a change in human habits and more efficient technologies. This article discusses one of the technological solutions that can reduce both greenhouse gas emissions and the release of PM2.5 and PM10 from individual heating systems in private homes and small commercial facilities. Calculations of electrical energy production in mCHP mode of the system for household self-consumption based on experiments will be done. The technology involves the production of heat from biomass or other types of renewable energy sources while generating electricity for self-consumption. Conclusions of CHP mode on overall efficiency will be done.

Livestock cause around 10% of total greenhouse gas (GHG) emissions in the European Union. Despite the large quantities, no economic policy is in place to reduce emissions from the sector. In this paper, we introduce consumption taxes on animal products in the European Union to reduce GHG emissions. Impacts are simulated using the CAPRI model, which was created to analyze the impacts of agricultural policy reforms within the EU. Tax levels of 16, 60 and 290 Euro per ton of GHG emissions are used in the estimations. Our results show that consumption taxes have small mitigation effects, up to 4.9% of total agricultural emissions from the EU-27, mainly due to inelastic demand. The main source of reductions is beef and France is the country where most reductions would take place, given high levels of production and consumption in the country, combined with a large demand elasticity of beef.

As a contribution to the fight against climate change, ESNE’s 2018/19 carbon footprint has been evaluated using the CarbonFeel methodology, based on ISO 14069 standards. In the scenario studied, greenhouse gas (GHG) emissions produced by direct and indirect emissions have been included. For comparative purposes, a second scenario has been analyzed in which fossil fuels used for heating are replaced by electrical energy from renewable sources. A decrease of 28% in GHG emissions has been verified, which could even reach 40% if the energy for thermal conditioning was replaced by renewables.

Considering food security and climate change mitigation as the main sustainability challenges for agriculture, the main goal is to achieve agricultural production at an acceptable level of greenhouse gas (GHG) emissions. In this paper, the effects of GHGs are described. Panel data models are built to assess the impact of greenhouse gases on harvested production of cereals in EU countries. The study is focused on the climate change cause by GHG emissions that have a direct impact on agriculture in what concerns cereal production. Therefore, the impact of GHGs on cereal production in the European Union, except Malta, in the period 2000–2016 was assessed. Moreover, the effects of GHGs on agricultural irrigated land in Denmark and Hungary, two EU countries with the large agricultural surface, were computed. The results indicated a positive impact of GHGs from agriculture and fertilizer consumption in the previous year on cereal production in the EU. Moreover, only in Hungary did the increase in GHG emissions determined a slow increase in the volume of agricultural irrigated lands in the period of 2000–2016.

The problem of anthropogenic climate change is arguably one of the foremost pressing issues facing the world today. With that, governments around the world have been working together to put forward binding targets and agreements to reduce greenhouse gas emissions in their respective jurisdictions. The most famous example of these multilateral efforts has culminated in the Kyoto Protocol, which was formally ratified by the Canadian government in 2002. However, despite this ratification, the federal government has failed to meet its reduction targets or legislate any substantial policy that would effectively regulate and reduce emissions. Indeed, rather than seeing emission levels fall, Canada’s overall GHG emissions have increased substantially.1[...]

The European mitigation strategy for combatting climate change requires up-to-date knowledge about the environmental effects of greenhouse gas (GHG) emissions at the national scale. As a strong response to the consequences of climate change, the European Union has imposed on the member states an obligation to achieve the goals set out in the climate and energy package, which were aimed at reducing emissions. Therefore, underlying the trends of GHG emissions is essential when establishing climate change mitigation measures. This study identify the structure and dynamics of the GHG emissions of the six sectors of the European economies, over 27 years, and reveal the significance, direction, rate, and drivers of the observed trends using the method of modifying the absolute mean. The results indicate a decrease in the GHG emissions in the EU-28 by an average of 1% annually, which can be explained by a mixt factors, such as resize of the industry, improved energy efficiency, the growing share of renewables and less use of carbon fuels. Moreover, through the environmental policies adopted in the last decade, was observed that the GHG emissions level in 2017 had declined by approximately 25% in comparison with the reference (1990) and by approximately 17% by 2005. From the 28 EU countries (EU-28), Romania produced 4.2% of the total EU-28 GHG emissions in 1999, which decreased to 2.7% in 2005 and reaching 2.3% in 2017. Romania contributed to 14% of the average annual decrease in emissions. This evidence highlights the additional support for further reduction beyond that required for climate change mitigation.

The present work considers the dramatic changes the COVID-19 pandemic has brought to the global economy, with particular emphasis on energy. Focusing on the European Union, the article discusses the opportunities policy makers can implement to reduce the climate impacts and achieve the Paris Agreement 2050 targets. The analysis specifically looks at the fossil fuels industry and the future of the fossil sector post COVID-19 pandemic. The analysis first revises the fossil fuel sector, and then considers the need for a shift of the global climate change policy from promoting the deployment of renewable energy sources to curtailing the use of fossil fuels. This will be a change to the current global approach, from a relative passive one to a strategically dynamic and proactive one. Such a curtailment should be based on actual volumes of fossil fuels used and not on percentages. Finally, conclusions are preliminary applied to the European Union policies for net zero by 2050 based on a two-fold strategy: continuing and reinforcing the implementation of the Renewable Energy Directive to 2035, while adopting a new directive for fixed and over time increasing curtailment of fossils as of 2025 until 2050.

The text analyses the influence of the EU climate policy on the competitiveness pollution-generating of sectors of the Polish economy. Study of literature and the results of the questionnaire survey, carried out in 2008 in enterprises located in Poland and representing the steel, glass, aluminium and cement industries became a basis for formulating conclusions concerning the consequences of the climate policy already implemented and planned after 2012. The EU climate policy, particularly the common system of emission allowances trade, makes the enterprises face new developmental barriers. The expected increase in production costs will not only slow down the production dynamics, but may also entail lowering the competitiveness of Polish companies compared to companies from outside the EU, to which the greenhouse gasses emission limits do not apply. Adverse consequences for employment and for regional development should also be considered indisputable. If that was accompanied by an emission leakage outside the EU, achieving the global purposes of the climate policy would also become questionable. The businesses surveyed represent industries which are pollution generators by their nature and even ecologically-oriented technological progress is incapable of ensuring considerable emission reductions without general switching of the economy to renewable energy sources.

Climate change litigation is becoming increasingly important. This thesis deals with the question whether state liability claims against Germany or the EU can be justified, if commitments to reduce greenhouse gas emissions are not met. For this purpose, the claim under public liability according to § 839 German Civil Code in connection with Art. 34 German Basic Law, the liability of the EU-Member States and the liability of the European Union according to Art. 340 II TFEU are discussed. At the end of the thesis, considerations on the practical perspectives of state liability are made in order to improve their prospects of success.

Because current emissions accounting approaches focus on an entire city, cities are often considered to be large emitters of greenhouse gas (GHG) emissions, with no attention to the variation within them. This makes it more difficult to identify climate change mitigation strategies that can simultaneously reduce emissions and address place-specific development challenges. In response to this gap, a bottom-up emissions inventory study was undertaken to identify high emission zones and development goals for the Durban metropolitan area (eThekwini Municipality). The study is the first attempt at creating a spatially disaggregated emissions inventory for key sectors in Durban. The results indicate that particular groups and economic activities are responsible for more emissions, and socio-spatial development and emission inequalities are found both within the city and within the high emission zone. This is valuable information for the municipality in tailoring mitigation efforts to reduce emissions and address development gaps for low-carbon spatial planning whilst contributing to objectives for social justice.
