“…Today's air-conditioners rely on chemicals called HFCs (hydrofluorocarbons), which are potent greenhouse gases. HFCs have been used to replace ozone-depleting substances, and their emissions have increased rapidly in the past two decades (Purohit et al, 2022). Rapid industrialization is a significant contributing factor to the pollution ratio.…”

Today, the rapid development of technology has caused both positive and negative effects and environmental changes. While enjoying the convenience provided by technology, people should have the right mindset in keeping and protecting their environment healthy. Therefore, this study aims to examine the factors that impact the green product purchase behaviour of Malaysian shoppers in Klang Valley, Malaysia. Five independent variables were used in this research project to identify the factors that influence working consumers’ purchasing behaviour toward green products: social influences, environmental attitudes, environmental concern, and perceived effectiveness of environmental problems and perceived effectiveness of environmental behaviour. Six hundred consumers are the solely targeted respondents in this study. It is found that there are no significant differences for the gender and race variables, whereas the monthly income variable found a significant difference. In addition, the study findings also discovered a significant relationship between the factors influencing consumers’ purchasing behaviour towards green products. Consequently, these research findings have provided insights and feedback to businesses facing many challenges in convincing consumers to purchase green products. By gathering this information, marketers can understand the route that shifts the environmental factors to green purchase behaviour. They also would be able to formulate their various strategies to effectively attract more consumers to purchase green products.

“…Consequently, this multilateral treaty, ratified by all 198 United Nations member states, has prevented large-scale detrimental effects of elevated UV-B radiation on agricultural productivity, terrestrial organisms and ecosystems [ 2 – 4 ]. Moreover, because many of the ozone-depleting compounds regulated by the Montreal Protocol are also potent greenhouse gases, this treaty and its Kigali Amendment are playing an important role in mitigating global warming and other environmental effects of climate change [ 5 , 6 ].…”

Terrestrial organisms and ecosystems are being exposed to new and rapidly changing combinations of solar UV radiation and other environmental factors because of ongoing changes in stratospheric ozone and climate. In this Quadrennial Assessment, we examine the interactive effects of changes in stratospheric ozone, UV radiation and climate on terrestrial ecosystems and biogeochemical cycles in the context of the Montreal Protocol. We specifically assess effects on terrestrial organisms, agriculture and food supply, biodiversity, ecosystem services and feedbacks to the climate system. Emphasis is placed on the role of extreme climate events in altering the exposure to UV radiation of organisms and ecosystems and the potential effects on biodiversity. We also address the responses of plants to increased temporal variability in solar UV radiation, the interactive effects of UV radiation and other climate change factors (e.g. drought, temperature) on crops, and the role of UV radiation in driving the breakdown of organic matter from dead plant material (i.e. litter) and biocides (pesticides and herbicides). Our assessment indicates that UV radiation and climate interact in various ways to affect the structure and function of terrestrial ecosystems, and that by protecting the ozone layer, the Montreal Protocol continues to play a vital role in maintaining healthy, diverse ecosystems on land that sustain life on Earth. Furthermore, the Montreal Protocol and its Kigali Amendment are mitigating some of the negative environmental consequences of climate change by limiting the emissions of greenhouse gases and protecting the carbon sequestration potential of vegetation and the terrestrial carbon pool.

“…More climate benefits can be achieved by taking earlier action. 7,24,25 If the production of HFCs ceases in 2023, radiative forcing could be reduced to about 0.03 W/m 2 by 2050; 7 if HFC emissions cease by 2030, more than 90% of the climate impacts associated with HFCs could be avoided. 25 Therefore, achieving zero HFC emissions as soon as possible will help mitigate temperature overshoot and achieve more significant climate benefits.…”

Global hydrofluorocarbon (HFC) cumulative emissions will be more than 20 Gt CO2-equiv during 2020–2060 and have a non-negligible impact on global warming even in full compliance with the Kigali Amendment (KA). Fluorochemical manufacturers (including multinationals) in China have accounted for about 70% of global HFC production since 2015, of which about 60% is emitted outside China. This study built an integrated model (i.e., DECAF) to estimate both territorial and exported emissions of China under three scenarios and assess the corresponding climate effects as well as abatement costs. Achieving near-zero territorial emissions by 2060 could avoid 23 ± 4 Gt CO2-equiv of cumulative territorial emissions (compared to the 2019 Baseline scenario) during 2020–2060 at an average abatement cost of 9 ± 6 USD/t CO2-equiv. Under the near-zero emission (including territorial and abroad) pathway, radiative forcing from HFCs will peak in 2037 (60 ± 6 mW/m2) with a 33% peak reduction and 8 years in advance compared to the path regulated by the KA, and the radiative forcing by 2060 will be lower than that in 2019. Accelerated phase-out of HFC production in China could provide a possibility for rapid global HFC abatement and achieve greater climate benefits.
