Abstract
Greenhouse gases are: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. In December 2020, the European Council approved a new target for reducing greenhouse gas emissions by 2030 and a net domestic emission reduction of at least 55% compared to 1990, and climate neutrality for 2050. Careful monitoring of emissions is needed to achieve these goals. The paper aims to evaluate and compare the carbon dioxide emission coefficient, in the case of burning different fuels: petroleum fuels and biofuels. The calculation model was developed based on the mathematical relationships taken from specific publications. Kerosene, Liquiefied Petroleum Gas, Gasoline COR 95 Euro 5 and Diesel Euro 5 are the petroleum fuels used in the study. The used biofuels are: Bioethanol, Biobuthanol, Biodiesel (soybean) and Biodiesel (rapeseed). The results provide data on the amount of CO2 that reaches into the atmosphere. Based on the information obtained, a fuel ranking can be made and decisions can be taken regarding their choice.
Highlights
Carbon dioxide, methane and nitrogen protoxide are the main greenhouse gases
The concept of sustainable development is part of the strategy of the European environment policy. It refers to the reduction of the greenhouse gas (GHG) emissions [1, 2]
In September 2020, the Commission proposed to reduce the GHG emissions by 55% until 2030 in comparison with the 1990 levels and a neutrality of carbon dioxide emissions by 2050 [3]
Summary
Methane and nitrogen protoxide are the main greenhouse gases. They prevent the release of terrestrial heat into space, causing global warming. For years 2016 – 2030, Romania suggests a national strategy regarding economic growth and climate change based on low carbon emissions. According to this plan, the global share of energy from renewable sources in the final gross energy consumption is 30.7 %. The Integrated Carbon Observation System (ICOS) quantifies the GHG balance in Europe and other regions It is a research infrastructure which provides key observations of the greenhouse gas emissions. Around the world, the energy demands have been incredibly altered by the Government policies It has been a decrease by 17 % of the daily global CO2 emissions by early April 2020 compared with the 2019 levels. The duration of the restrictions enforces the impact on 2020 annual emissions [10]
