The awareness of the environment, climate, and nature that emerged worldwide in the 1970s has paralleled the actions taken in the European Union (EU) under the United Nations. In the EU, the environmental title was given a legal basis for the first time with the entry into force of the Single European Act, and action on the environment and climate change became the main priorities of the EU in all areas with the amendments in the founding treaties. This study examines environmental and climate policy in the EU and the process known as the green transition in the EU. The study consists of three sections. The first section discusses the environment and the development of climate change awareness in the world and the EU, while the second section underlines the EU's environmental and climate change approaches and policies. The third and final section highlights the development and green transition strategy adopted by the EU in 2019 and the “Green Deal” strategy paper. The study concludes that the “Green Deal” is at the heart of the so-called green transition process in the EU, that the goals sought by the Deal are very ambitious, that it is almost impossible to achieve the corresponding goals without an effective/coercive political mechanism, and that the EU is planning a green transition rather than a green transformation.

How are our cities confronting the challenges posed by a warming climate, the loss of biodiversity, and the increasing urban heat island effect? ― This chapter discusses the opportunities and benefits of applying the concepts of renaturalization and rewilding of cities. It introduces nature-based solutions (NBS) in urban planning that are integrated with the aim to enhance urban resilience and to slow down the biodiversity decline, which can be applied in two areas: through the conception of new green neighborhoods and through the regeneration and regreening of existing but neglected parts of the city, such as postindustrial brownfields or economically weak districts.

Contact to nature is essential for human existence, urban well-being, and a good quality of life. Green spaces in cities – big or small – all contribute to health and well-being. However, many cities do not offer residents easy access to green space within the city. Improving better access and extending gardens and parks will deliver a large number of benefits, such as ecosystem services, better water management for enhanced urban flood control, and slowing down the biodiversity loss, with the potential to restore damaged ecosystems. Furthermore, additional green space and NBS help to keep cities cool during heat waves and improve the urban microclimate.

In this context, NBS and regreening can generate significant benefits for citizens, improve urban health and well-being, and offer an opportunity to effectively deploy nature to resolve major societal challenges ― such as social inclusion, food security, and disaster risk reduction. However, it is essential that the design of NBS is fully integrated with other complementary planning interventions and seeks synergies across all sectors.

The hotel sector in South Africa is also aware of the detrimental impact of its activities on the environment. As a result, it has taken steps to mitigate such effects, evidenced by implementing green hotel practices. ‘Green hotels’ refers to lodging establishments that try to consume less energy, water and materials while still offering high-quality services. Unfortunately, although the hotel sector contributes significantly to employment and economic growth globally, its activities harm the environment through pollution, overuse of natural resources and solid and liquid waste.

This chapter discusses the concepts of green hotels and green practices. This chapter also highlights the need for green practices and identifies a case study on green hotels and practices in a South African context. This chapter found that the green hotel sector implements green practices, such as water-saving practices due to the risk of water insecurity, the growing demand for sustainability and the necessity to boost revenues. Green hotels and practices are a step to actualise the objectives of Sustainable Development Goals (SDGs) 12 and 13, which focus on clean water and sanitation and climate change, respectively. The study underscores the importance of green practices and how South Africa responds to the challenge. It is believed that hotels contribute significantly to environmental degradation, but they can also help to preserve the environment through their activities through green practices. Strategies like adopting green practices would be a remedy to mitigate pollution and its effects on environmental sustainability.

The chapter explores how tourism creates even more dependence as spaces become gentrified and too expensive for local occupation through colonial tropes, and accumulation models. Tourism consumes gently. In the wake of Hurricanes Irma, Maria, and Dorian, The Bahamas and Puerto Rico have experienced an accelerated strike on their natural and social resources: from land deals and tax concessions to power infrastructure and school closures. Debt has plagued the countries; the policies designed to get them out of debt prior to the natural disasters, then converted into man-made disasters, have only deepened dependence and indebtedness. In fact, both have become externalized communities where land is being accumulated through dispossession. Tourism is more than just hotels and resorts; it is now the gated communities and private islands that build on coloniality and inequalities. Tourism, disaster capitalism, and green grabbing accumulate by dispossessing locals of land in the name of improving their economic health. Economic well being seems to result in loss.
