WHAT HAS YOUR AIR CONDITIONING GOT TO DO WITH THE WORLD CLIMATE AND HOW MUCH DOES IT COST?

Kigali Project

Air-conditioning is important for well-being and even for health. However, in Brazil it consumes a significant amount of energy and has an environmental impact. More efficient air-conditioning respects the environment and reduces the cost of the electricity bill. The Kigali Project aims to help change the energy consumption profile of air conditioners in Brazil by adopting the best international practices. It also encourages the use of refrigerants that have a low potential for global warming.

A COUNTRY WITH HEATED NUMBERS

Today, one in every five Brazilian households has at least one air conditioner. With the increase in temperature and the number of hotter days, which are caused by climate change, this amount is growing. Air-conditioning provides thermal comfort but it is also responsible for greenhouse gases emissions, as well as accounting for a considerable portion of the cost of electricity bills.

Current Household Energy Demand

Air-conditioning will soon become the the main item in residential and commercial eletricity consumption.

The time for the peak use of air-conditioning is from noon to mid-afternoon, which is precisely when the peak demand for electricity occurs. This makes it necessary to activate thermal power plants, which are more polluting and more expensive – and makes energy tariffs increase. In addition, the vast majority of the equipment available today in Brazil uses HCFC-22 and HFC-410A refrigerants, which are substances that add significantly to greenhouse gas emissions. For example, the global warming potential of these substances is two thousand times greater than CO2!

The best way to tackle this problem is to increase the energy efficiency of air conditioning equipment and also to replace refrigerants with less potential for global warming – as provided for in the Kigali Amendment.

The models currently available in Brazil are less efficient compared to the standards adopted in most countries and changing this situation is much simpler than it seems. The air conditioning sector has great potential for this change. More efficient air-conditioning respects the environment and, in the medium and long term, also costs less for the consumer – and for you!

MORE EFFICIENCY, LESS WARMING;
MORE EFFICIENCY, LOWER ELECTRICITY BILL

If we were to use 30% more efficient air conditioning than today in Brazil, by 2030 we could save 32 GW of electricity at peak times, avoiding the activation of 52 medium-sized thermal power plants. We would also reduce greenhouse gas emissions from the electricity sector by. 23%, i.e., there will be the equivalent of 16.79 million tons of CO2 that is not released into the atmosphere.

Total equipment

There are about 1.6 billion air conditioners in commercial and residential use.

Sales in 2016

In 2016 alone, almost 135 million units were sold.

g

Consumption

They consume about 2,000 Terawatt-hours (TWh) – the equivalent of 5x the energy production of all the combined Brazilian hydroelectric plants in 2016.

10% of Generated Energy

This consumption corresponds to 10% of all the electric energy generated on the planet (21,000 TWh).

Emissions

It represents the emission of 1,150 MtCO2 (Metric tonnes of carbon dioxide equivalent).

Total Emissions

If we include the emissions from refrigerants, this number rises to 1,450 MtCO2, or 4.5% of the global CO2 emissions from the energy sector

At the current rate, if nothing is done, the cooling will represent
20% of global greenhouse gas emissions by 2050.
