Pandemi Covid-19 telah mengubah pola mobilitas masyarakat. Pembatasan pergerakan harian diperkirakan akan mengubah banyak aspek dalam kehidupan manusia, termasuk diantaranya persepsi pada interaksi dan aktivitas secara daring, penggunaan kendaraan umum, maupun pola konsumsi. Penelitian ini mengonfirmasi bahwa secara umum terjadi reduksi jejak karbon setelah pandemi Covid-19 menyerang. Penelitian ini fokus pada kelompok mahasiswa yang mengalami perubahan karakteristik aktivitas perkuliahan semenjak pandemi. Data tentang frekuensi pergerakan, penggunaan peralatan listrik, dan konsumsi makanan dikumpulkan dari populasi mahasiswa Perencanaan Wilayah dan Kota Universitas Sebelas Maret sebagai dasar perhitungan perubahan jejak karbon mahasiswa sebelum dan saat implementasi kebijakan belajar dari rumah. Analisis dengan metode kuantitatif menunjukkan bahwa jejak karbon mahasiswa berkurang, baik pada aspek kegiatan harian, aktivitas akademik maupun transportasi. Persentase terbesar pada aspek akademik ditunjukkan dengan lebih dari 80% pengurangan penggunaan kertas. Perubahan lingkungan tinggal mahasiswa menunjukkan bahwa mahasiswa yang kembali ke rumah mencatat penurunan jejak karbon yang lebih besar ketimbang mahasiswa yang masih bertahan untuk tinggal di kost di sekitar kampus UNS. Perubahan kebiasaan dalam aktivitas harian mahasiswa selama pandemi menunjukkan bahwa pandemi membawa efek positif dalam pengurangan jejak karbon. Penelitian ini merekomendasikan kolaborasi pembelajaran dalam jaringan dengan luar jaringan pada saat pandemi berakhir untuk mengurangi jejak karbon mahasiswa dalam jangka waktu yang lebih lama.

Climate change is one of the global issues that require the participation of all stakeholders for handling. In addition, the climate change issue is listed as one of the sustainable development goals (SDGs). The Government of Mataram city, as one of the stakeholders, has committed to involve the climate change consideration into its planned program, including the development of agro-edutourism facility. This study aims to calculate a carbon footprint of agroedutourism facility during the operational stage in order to implement the Greenhouse Gas (GHG) emission reduction strategy. The method used is a life cycle assessment approach with ReCiPe analysis, and the functional unit is an annual carbon footprint per m² area of agro-edutourism. The study showed that the total carbon footprint per m² was 2.88 KgCO2-e per annum with the primary environmental hotspot was fossil fuel utilization in energy source of agro-edutourism facility (Electricity State-own Company) and visitor vehicles. Therefore, some strategies could be applied for reducing the carbon footprint, such as increasing the utilization percentage of renewable energy (solar panel), using energy-saving bulbs, preparing the facilities for zero-emission vehicles, and applying the green building concept or design. Further research is required to assess the energy management concept from the technical feasibility aspect and economic aspect for complimenting this study. [ABSTRACT FROM AUTHOR]

Climate change is one of the biggest challenges faced by cities of the developing world. Of no exception is the rapid development in Kuala Lumpur, the capital city of Malaysia. Like other developing cities, the emissions of greenhouse gases (GHG), such as carbon dioxide (CO2) from activities in the urban areas, industrial and emissions from motor vehicles. The objective of this study is to analyze the carbon footprint of the human breathing and the ability of green spaces (large gardens) to absorb the release of CO2 from breathing activities in Kuala Lumpur. An that 1,406 million kg tonnes CO2 / man / year were released by 1.67 million people in Kuala Lumpur. The release of CO2 from humans in Kuala Lumpur was estimated at 559,906.56 tonnes / man / year, while the CO2 absorption capacity for large gardens was 484,367.62 tonnes / man / year. The implication of this study showed that the total area of plants were not capable in absorbing the released carbon within the city. [ABSTRACT FROM AUTHOR]
