The framework, introduced in 2009 by co-author Professor Johan Rockström and colleagues, defines Planetary Boundaries as the safe operating thresholds for nine critical processes that maintain Earth system stability and resilience. The stratospheric ozone layer is one of the nine processes, and it is highlighted as the first and only example of a planetary system imperiled by humans yet pulled back towards health in the coming decades by collective action of scientists, consumer boycotts, public policy, and technical innovation. This paper explains how policymakers, facing an existential risk from fluorocarbon emissions, listened to science and acted at a global level with adoption of the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) that, along with complementary actions by citizen and corporate leaders, avoided health and environmental hazards of stratospheric ozone depletion. The paper also explains how the Montreal Protocol has delayed climate tipping points through:

1) the phaseout of ozone-depleting substances (ODSs) that are also powerful greenhouse gases (GHGs),

2) the ongoing phasedown of non-ozone-depleting hydrofluorocarbon (HFC) GHGs, and;

3) the associated protection of aquatic and terrestrial carbon sinks from ultraviolet (UV) radiation.

The Montreal Protocol is proof that humans can organize to protect the global commons against exceeding planetary boundaries. The paper shows how it is possible to restore the health of other planetary boundaries beyond stratospheric ozone and climate by using the Montreal Protocol’s successful model of trusted scientific and technical wisdom, deep human connections, and a commitment to fairness.

Includes a Case Study of MAC Secondary-Loop Architecture Vital to Economic and Environmental Performance of All-Electric Vehicles.

This publication offers the back and front story, the timeline, and the comprehensive bibliography of leadership in the full spectrum of environmentally improved motor vehicle air conditioning, including ozone-safe and climate-friendly refrigerants, leak-tight systems, repair before recharge with recovery and recycle, energy efficiency, and end-of-life recovery and recycle or destruction. It also elaborates on the partnerships that developed secondary-loop motor vehicle air conditioning (SL-MAC), which is a powerful driver of improved performance of all-electric vehicles that are necessary to avoid climate tipping points. The co-authors are insiders to this technical breakthrough.

SL-MAC technology developed through collaboration between government and industry is almost patent-free and is easily adaptable to the special circumstances of passenger and commercial vehicles, small or large, on-road or off-road, and internal combustion, hybrid, or all-electric.

By phasing out production and consumption of most ozone-depleting substances (ODSs), the Montreal Protocol on Substances that Deplete the Ozone Layer (Montreal Protocol) has avoided consequences of increased ultraviolet (UV) radiation and will restore stratospheric ozone to pre-1980 conditions by mid-century, assuming compliance with the phaseout. However, several studies have documented an unexpected increase in emissions and suggested unreported production of trichlorofluoromethane (CFC-11) and potentially other ODSs after 2012 despite production phaseouts under the Montreal Protocol. Furthermore, because most ODSs are powerful greenhouse gases (GHGs), there are significant climate protection benefits in collecting and destroying the substantial quantities of historically allowed production of chemicals under the Montreal Protocol that are contained in existing equipment and products and referred to as ODS “banks”. This technical note presents a framework for considering offsets to ozone depletion, climate forcing, and other environmental impacts arising from occurrences of unexpected emissions and unreported production of Montreal Protocol controlled substances, as recently experienced and likely to be experienced again. We also show how this methodology could be applied to the destruction of banks of controlled ODSs and GHGs or to halon or other production allowed under a Montreal Protocol Essential Use Exemption or Critical Use Exemption. Further, we roughly estimate the magnitude of offset each type of action could provide for ozone depletion, climate, and other environmental impacts that Montreal Protocol Parties agree warrant remedial action.

The Global Cooling Watch report, Keeping it Chill: How to meet cooling demands while cutting emissions – by the UN Environment Programme-led Cool Coalition – lays out sustainable cooling measures in three areas: passive cooling, higher-energy efficiency standards, and a faster phase down of climate-warming refrigerants. The report is released in support of the Global Cooling Pledge, a joint initiative between the United Arab Emirates as host of COP28 and the Cool Coalition. 

IGSD Chief Scientist Dr. Gabrielle Dreyfus served as the lead topical author of the chapter on refrigerants.

This paper reviews MLF accomplishments, summarizes TEAP assessment of funding required to replenish MLF, and offers analyses of the benefits that could be achieved with more funding.

In an effort to provide insight into six Southeast Asian (SEA) markets at risk of environmental dumping, CLASP and IGSD assessed the RAC markets for Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. The six countries represent 90% of the regional SEA market.

Currently energy efficiency policies in Southeast Asia lag behind the innovation in RAC technology and the policies of surrounding countries. As low-efficiency and high global warming potential refrigerants are banned in markets around the world, SEA is at risk of becoming a dumping ground for obsolete appliances manufactured by multinational companies that are banned in their own domestic markets. Rolling out and enforcing national energy efficiency policies coupled with accompanying measures would halt this trend.

The transition away from the production and consumption of high global warming potential (GWP) hydrofluorocarbons (HFCs) under the 2016 Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer has prompted air conditioning, refrigeration, and heat pump equipment manufacturers to seek alternative refrigerants with lower direct climate impacts. Additional factors affecting alternative refrigerant choice include safety (i.e., flammability and toxicity), environmental, and thermodynamic constraints. At the same time, manufacturers are incentivized to seek refrigerants with higher energy efficiency, which saves on electricity costs and reduces indirect greenhouse gas emissions from electricity generation. The life cycle climate performance (LCCP) metric is commonly used to assess the combined direct and indirect climate impacts of refrigerant-use equipment. Here, we consider an additional impact on climate performance: the degradation of refrigerant in equipment, i.e., the direct climate impacts of high-GWP byproducts that can form as the result of adding trifluoroiodomethane (CF3I) to refrigerant blends to reduce flammability. Such a production of high-GWP gases could change the acceptability of CF3I-containing refrigerants. Further, it highlights the need to understand refrigerant degradation within equipment in calculations of the environmental acceptability of new cooling technology.

Each year, one-third of the total food for human consumption is either lost or wasted even as millions worldwide experience food insecurity. Similarly, over 25 percent of vaccines are wasted each year while millions die from vaccine-preventable illnesses Sustainable cold chain infrastructure can significantly reduce post-harvest food loss and vaccine wastage and deliver social and climate benefits. However, acknowledging the need for cold storage alone does not ensure food security or access to vaccines, and must be supported by policies and resources, including technologies. Cooperation among G20 countries on cold chains can help coordinate the policies and resources necessary to advance food security, public health, and climate change mitigation.

Heating and cooling demand for space conditioning and refrigeration accounts for around a fifth of global final energy consumption. Climate change, urbanization, and economic development have tripled electricity demand for cooling alone since the 1990s, with the majority coming from the use of inefficient cooling equipment, which burdens electricity grids, especially during peak hours. It is imperative to address the energy required to provide cooling. The Kigali Amendment to the Montreal Protocol addresses these needs by setting ambitious global targets to phase down refrigerants with high global warming potential while improving energy efficiency. Integrating energy efficiency and the refrigerant transition will contribute to economic security, well-being, energy access and security, and sustainability among the G20 countries.

Environmentally harmful product dumping (“environmental dumping”) of new and used low-efficiency cooling appliances with obsolete ozone-depleting and greenhouse gas refrigerants in African countries impoverishes communities, hinders economic development, threatens ecological systems, and harms public health. The use of lowefficiency cooling appliances increases energy demand, leading to higher power plant emissions and limiting affordable energy access in African countries. These low-efficiency appliances and products contain ozone-depleting refrigerants with high global-warming potential (GWP) or ozone-safe refrigerants with high GWP. Environmental dumping of these appliances and products makes it more difficult for countries to meet their international climate obligations and for the world to meet the Paris Agreement’s climate change mitigation targets. Ghana faces high levels of environmental dumping, despite a national ban on importing used cooling appliances and established efficiency standards for new air conditioners and refrigerators. Through the Energy Commission’s Office of Renewable Energy, Energy Efficiency, & Climate Change (REEECC), the government of Ghana is partnering with the Institute for Governance & Sustainable Development (IGSD) to stop environmental dumping. This article provides a list of interventions that can be implemented by Ghana, by governments in countries that export to Ghana, and by industry and other stakeholders. Notably, these actions focus on the shared responsibility of exporting countries and manufacturers by calling on exporting countries to update and enhance enforcement of their laws, and on global manufacturers to stop exporting inefficient products with obsolete refrigerants to Ghana and other African countries.
