The sharing economy is an umbrella term for different business models that seem to have a positive impact on sustainability. To achieve sustainable development, the UN has created 17 Sustainable Development Goals (SDGs) as an instrument and guide for countries and individuals. This paper sheds light on the relationships between the sharing economy, sustainability and SDGs through the content analysis of 74 papers from the database Web of Science that consider these factors through the topics of the environment, consumer values, business characteristics and urban impact regarding sectors such as mobility and accommodation. Results express that the sharing economy helps to achieve all SDGs. However, further research is needed because of the novelty of the topic and the existence of many gaps. The sharing economy has a positive effect on the dimensions of sustainability from the economic, social and environmental points of view.

Purpose: This paper takes a critical view of synergies and trade-offs and discloses the practices that countries and companies should apply to achieve sustainable development.Design/methodology/approach: This paper offers a systematic literature review of 408 papers to find models of sustainable development goals (SDGs) interaction with the aim of shedding light on the existing synergies and trade-offs and finding solutions to enhance these synergies and minimize the trade-offs.Findings: Both rich and developing countries should follow multiple strategies to improve the quality of life of their citizens. Developing countries should focus on eradicating poverty. Rich countries should apply new economic models that are more likely to be environmental-friendly. Finally, the topic of SDGs should be revisited by the United Nations.Practical implications: Boosting the quality of education and providing clean energy are two of the most relevant actions that should to be taken by countries, as they will accelerate the fulfilment of all the other SDGs. The use of circular economic models or new business models, such as the sharing economy, is essential to the achievement of sustained economic growth without negative environmental impact.Originality/value: The paper analyzes SDG interactions and offers a critical vision of practices that countries and companies should adhere to for achieving sustainable development.
