COP28's Cooling Pledge:68% Emission Reduction Target by 2050



  Oct 31, 2023

COP28's Cooling Pledge



Context:

The COP28 climate summit is set to unveil a "cooling pledge" aimed at reducing cooling-related emissions by 68% by the year 2050. Cooling technologies, like air conditioners and refrigerators, currently contribute to over 7% of global greenhouse gas emissions.

Key Points:

Emissions Target: The pledge seeks a 68% reduction in cooling-related emissions by 2050 compared to 2022 levels.

High-Stakes Players: Countries like China and India, where the demand for cooling technologies is surging, have not yet committed to the pledge.

UN Warning: The United Nations warns that without policy changes, emissions from cooling technologies could rise 90% above 2017 levels by 2050.

Global Impact: Cooling technologies are significant but short-lived pollutants with potentially exponential global warming effects.

Agenda: The summit will also discuss other crucial climate issues like fossil fuels, renewable energy, and financial arrangements for adaptation in the developing world.

Implications:

The cooling pledge could be a milestone in global efforts to curb climate change. However, its success largely depends on the participation of countries with rapidly growing demand for cooling technologies.

Cooling Technologies 101: A Brief Overview

Introduction:

Cooling technologies encompass a range of devices designed to lower temperatures and provide comfort or preserve resources. These devices include air conditioners, refrigerators, freezers, and fans, among others.

Key Components:

Air Conditioners: Use refrigerants to remove heat from indoor air and release it outside.

Refrigerators and Freezers: Employ a cooling cycle to maintain low temperatures and preserve food.

Fans: Circulate air but don't change temperature. Effective for immediate comfort.

Cooling Towers: Used in industrial settings to remove excess heat from machinery or buildings.

Chillers: Cool water or other liquids used in various industrial applications.

Environmental Impact:

Greenhouse Gas Emissions: Cooling technologies are responsible for over 7% of global greenhouse emissions.

Energy Consumption: These devices often require significant amounts of electricity.

Refrigerants: Some older technologies use CFCs or HCFCs, harmful to the ozone layer.

Alternatives and Improvements:

Eco-friendly Refrigerants: Replacements for harmful CFCs and HCFCs are being developed.

Energy-Efficiency: Newer models aim to provide the same cooling effect with less energy.

Natural Cooling: Techniques like green roofs and passive solar design aim to reduce the need for mechanical cooling.
