Sustainable Development: Challenges in Energy and Environment Economy

Dear Colleagues，

Since the onset of the Russian–Ukrainian conflict, Russia has threatened to cut off energy supply to Europe, forcing countries to start thinking about their own energy security. Different alternatives face various difficulties. The development of traditional fossil energy is facing the problems of increasing carbon emissions and environmental pressure, which will increase the cost of energy use and the risk of energy security in reliant countries. The replacement of traditional fossil energy by clean energy and nuclear power is difficult to achieve in the short term. In addition, the sources of uranium supply that the development of nuclear power relies on are concentrated in Australia, Canada, Russia, etc., which leads to more opposing viewpoints between those who advocate and oppose the development of nuclear energy. At the same time, the development of nuclear power also faces difficulties in safety and spent fuel disposal. Improving energy efficiency through technological innovation and increasing investment in energy-saving projects are faced with the dilemma of insufficient capital investment. The energy and environmental trade-offs facing developing countries are even more severe. Therefore, in the context of the Russian–Ukrainian conflict, it is of great theoretical and practical value to discuss energy accessibility, alternative energy options, energy prices and energy security, and the role of finance in improving energy security.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
