Net-zero carbon emissions: Plan to limit global warming to 1.5°C by 2050

By 2035, internal combustion engine vehicles will be discontinued

Net-zero carbon emissions is an international scientific consensus to reduce global warming by the second half of the twenty-first century.

To prevent the worst climate damage, net global human-caused carbon dioxide (_CO2) emissions must be reduced by about 45% from 2010 levels by 2030, reaching net zero around 2050.

Global warming is proportional to cumulative_CO2 emissions, meaning the planet will continue to warm as long as global emissions remain above freezing.

This implies that climate damage, caused by global warming, will continue to increase as long as emissions continue.

The path to reach the proposed goal in 2050 passes through the following milestones, according to the International Energy Agency (IEA).

Fossil fuel heaters should be phased out by 2025.

These consist of cauldrons powered by coal, gas or oil, which transmit heat to buildings through pipes with water.

This year, 50% of the electricity generated in the world should come from sources with low_CO2 emissions.

By 2030, 60% of new vehicles on the market are expected to be electric. At least 8% of the emissions generated by cement production are expected to be stored and stored.

In the cement industry, large amounts of CO2 are emitted, about one ton of_CO2 for every ton of _clinker.

About 40% comes from burning fuels, fine grinding and others.

The remaining 60% originates from the decarbonization of limestones to form the minerals that make up Clinker.

goals

The main objectives for 2035 are as follows:

The world’s most advanced economies must reach net zero_CO2 emissions in their electricity sectors.

That will be the last year that personal transport vehicles with internal combustion engines will be produced. Commitments in this regard by developed countries are encouraging.

It is aimed at three gigatons (3,000 million tons) of carbon emissions have been captured.

This process consists of storing carbon dioxide emissions generated in industrial production, which is then transported and accumulated in geological formations underground.

By 2040, electricity is expected to account for 40% of the total energy consumed in industries.

50% of the buildings will have to be retrofitted to a ready level of zero carbon emissions.

This year it is expected that five gigatons of_CO2 can be captured.

The production of trucks and other forms of high-tonnage transport with internal combustion engines should end by 2045.

Also, 50% of the heating needs will have to be covered by the use of heat pumps. The technology used by the latter does not generate heat itself.

What they do is redistribute the temperature of the air or the ground, through a refrigerant that circulates between the indoor unit of the fan coil (water-air conditioning device) and the outdoor compressor to transfer the heat.

In cooling mode, this system absorbs heat from inside the home and releases it to the outside.

2050

Finally, by 2050 it is intended that 90% of the electricity generated comes from renewable sources.

Currently, wind and photovoltaic are the fastest growing alternatives globally.

New technological developments are expected to accelerate change.

Electrolysis is a promising option for producing_CO2-free energy, splitting water into hydrogen and oxygen.
