Change Mitigation

COVID-19 has had wide-ranging impacts on organisations with the potential to disrupt efforts to decarbonise their operations. To understand how COVID-19 has affected the climate change mitigation strategies of Airport Operators (AOs), questionnaires and semi-structured interviews with Sustainability Managers were undertaken in late 2020 amidst a period of disruption. While all reported that COVID-19 impacted delivery of interventions and projects to mitigate climate change, the majority stated that it would not impact their long-term climate goals, such as Net Zero by 2050. The most popular climate change mitigation interventions AOs intend to deploy between now and 2030 are on-site renewables and Electric Vehicles and related infrastructure. Engineered carbon removal interventions were considered highly unlikely to be deployed in this timeframe, with potential implications for Net Zero decarbonisation pathways. Despite the severe impacts of COVID-19 on the sector, results indicate that AOs remain committed to decarbonisation, with climate change action remaining the key priority for airports. Given ongoing financial and resource constraints, AOs will need to explore new business models and partnerships and nurture collaborative approaches with other aviation stakeholders to not only maintain progress toward Net Zero but “build back better”. Government support will also be needed to stimulate the development of a sustainable, resilient, low-carbon aviation system.

Global wind resources greatly exceed current electricity demand and the levelized cost of energy from wind turbines has shown precipitous declines. Accordingly, the installed capacity of wind turbines grew at an annualized rate of about 14% during the last two decades and wind turbines now provide ~6–7% of the global electricity supply. This renewable electricity generation source is thus already playing a role in reducing greenhouse gas emissions from the energy sector. Here we document trends within the industry, examine projections of future installed capacity increases and compute the associated climate change mitigation potential at the global and regional levels. Key countries (the USA, UK and China) and regions (e.g., EU27) have developed ambitious plans to expand wind energy penetration as core aspects of their net-zero emissions strategies. The projected climate change mitigation from wind energy by 2100 ranges from 0.3–0.8 °C depending on the precise socio-economic pathway and wind energy expansion scenario followed. The rapid expansion of annual increments to wind energy installed capacity by approximately two times current rates can greatly delay the passing of the 2 °C warming threshold relative to pre-industrial levels. To achieve the required expansion of this cost-effective, low-carbon energy source, there is a need for electrification of the energy system and for expansion of manufacturing and installation capacity.

Change Mitigation

The paper deals with the exposition of the main barriers and drivers of renewable energy usage in rural communities. Climate change mitigation is causing governments, policymakers, and international organizations worldwide to embark on policies, leading to increased use of renewable energy sources and improvement of energy efficiency. Climate change mitigation actions, including the Green Deal strategy in the EU, require satisfying the expanding energy demand and complying with the environmental restrictions. At the same time, the prevailing market structure and infrastructure relevant to the energy systems are undergoing a crucial transformation. Specifically, there has been a shift from centralized to more decentralized and interactive energy systems that are accompanied by a low-carbon energy transition. Smart Grid technology and other innovations in the area of renewable energy microgeneration technologies have enabled changes in terms of the roles of energy users: they can act as prosumers that are producing and consuming energy at the same time. Renewable energy generation that is allowing for deeper involvement of the citizens may render higher social acceptance, which, in turn, fuels the low-carbon energy transition. The collective energy prosumption in the form of energy cooperatives has become a widespread form of renewable energy initiatives in rural communities. Even though renewable energy consumption provides a lot of benefits and opportunities for rural communities, the fast penetration of renewables and energy prosumption encounter several important barriers in the rural areas. This paper analyses the main barriers and drivers of renewable energy initiatives in rural areas and provides policy implications for the low-carbon energy transition in rural areas.

Faced with forthcoming international obligations related to climate change mitigation measures, primarily planned to be reflected through the Law and Action Plan on Low Carbon Development Strategy, as well as the Law on Climate Change, all of which are currently being defined and adopted, Serbia is increasingly facing a need to switch its coal-fired facilities to alternative, environmentally more acceptable options. The related measures will have to be implemented much sooner than initially planned. Knowing that 80% of national GHG emissions originate from the energy sector, as well as that the dominant portion of those emissions results from the use of locally available coal, it is clear that the most efficient climate change mitigation measure would be a switch to alternative fuel options. However, having in mind that such an energy transition process is coupled with significant technological, environmental, economic, social, and other difficulties, the EU has initiated several projects, and one of them is TRACER, launched under the Horizon 2020 program, that strives to shed light on the best research and innovation strategies facilitating easier transition to the sustainable, low carbon energy system. The project addresses actions across nine coal-intensive European regions, including Kolubara Region in Serbia. The paper presents technological, environmental, and social challenges in the transition process, with an emphasis on the Kolubara region, and a proposal for the energy transition in Serbia respecting R&I strategies and Smart Specialization.

Change Mitigation

Through a dynamic model of energy system change the paper examines the role of innovation in bringing about a low carbon energy system. The processes of innovation and technological substitution are cumulative, dynamic, and highly non-linear processes such that how the energy system evolves in the long term is extraordinarily sensitive to the strength and duration of the initial policies. It is possible, under some policy assumptions, that energy systems would continue to depend on fossil fuels for so long as fossil fuels remain abundant and the least cost resource; and under other assumptions, after allowing for the unavoidable lags associated with investment and the building up of a new capital stock, that fossil fuels would become almost wholly displaced by the non-carbon alternatives. The implication is that the external benefits of innovation, which include the creation of options and the reduction of costs arising directly from innovation itself, and the reduction of environmental damage, are far greater, perhaps by orders of magnitude, than the traditional cost–benefit models used for the analysis of climate change mitigation. The analysis suggests why a focus on discovery and innovation offers a promising way forward for national and international policies on climate change.
