Macau is a Special Administrative Region (SAR) of the People's Republic of China. The Macau SAR government aims to develop Macau into a sustainable city. In 2010, Macau implemented regulations and policies for solar energy development, which has encouraged the country to take on the approach of rooftop solar panels and grid-connected photovoltaic systems. Macau is set to build into a smart city with its development plan that started in 2016, making positive progress. In addition, e-payment, e-banking, and e-government have considerably eased the Macanese livelihood during the global COVID-19 pandemic. What's more, the Macanese are wisely and passionately embracing plant-based foods. Currently, Macau has over 25 vegan/vegetarian restaurants.North Macedonia is a small nation in the Balkan Peninsular of Southeast Europe.

Madagascar actively promotes solar energy which has stimulated continuous economic growth from 2010 to 2019 for 20% of the population in urban areas. The government aims to benefit the rural areas by increasing the electricity connection rate to 70 % by 2030. In January 2017, the Malagasy government implemented a new nationality law guaranteeing equal rights for women and men to bestow their nationality on their children. Heavy forest loss in Madagascar has brought a tremendous threat to its exceptional biodiversity and the livelihood of rural communities. Recognizing this, on January 19, 2020, Madagascar launched a national drive to plant 60 million trees. His Excellency President Rajoelina's administration initiated a plan to plant 40,000 hectares per year.
