There is clear agreement among scientists that climate change is accompanied by more frequent and intense natural disasters, from droughts and wildfires to hurricanes and coastal floods. While the exact extent of the economic damage cannot be determined, there is strong evidence that the damage may be Too severe. The challenge facing policymakers is In determining the amount of spending on measures to reduce gas (Co2 emission ) greenhouse. And to do that, they have to be able to compare Contingent options costs, including renewable energy sources and electric cars.
This challenge has become more pressing in the world of politics, with climate scientists stressing that emissions reductions must be rapid and deep, with a view to bringing net emissions to zero by 2050.
To calculate the cost of reducing greenhouse gas emissions in the short term, economists estimate the upfront cost and divide it by the amount of carbon dioxide sequestered (tonnes or equivalent). For example, suppose the government spends $20 million to encourage the development of wind farms to generate electricity and reduce million tons of carbon dioxide emissions, so the cost of reducing emissions will be $20 per ton. This method is a useful way to compare the cost of different ways to reduce emissions.
A significant reduction in greenhouse gas emissions requires the necessary cost accounting So in the long run. Kenneth Gillingham
Renewable energy technologies are among the least expensive technologies ever compared to the technologies currently used in the generation of electricity from coal (In dollars per ton of carbon dioxide, based on 2018 dollar value.
Most surprisingly, renewable energy technologies are the least expensive of all. (This finding can be applied outside the United States since most of these technologies for renewable energy are traded in global markets.) In fact, the cost of using wind or solar energy may be lower than forecasts if implicit or explicit subsidies are taken into account.
However, these estimates do not account for interruptions in renewable energy generation—the sun doesn’t shine and the wind doesn’t blow all the time and in cases where large amounts of energy are not used, storage technologies should be used as a complement to renewable energy, such as hydroelectric storage, batteries, or other forms of power generation that can quickly fill the gap when wind or solar power fades.
Is it possible to reduce carbon emissions enough to come close to meeting the net-zero emissions target by 2050? Yes, it is even possible nowadays — the technologies for this already exist. But this massive transformation of the energy system will be costly and difficult if we try to complete it in one step, especially because of the huge cost of this transition in the short term in developing countries dependent on fossil fuels. There are, of course, inexpensive measures that can now be implemented, including energy conservation, efficiency incentives, and the replacement of fossil fuels by renewable energy in electric power generation.
And if we take into account the estimated social cost of carbon, these measures will actually be less costly compared to the cost of climate change damage that could be avoided through these measures. But many other approaches are too costly in the short term, especially the effort to encourage the use of new low-carbon technologies. However, policies that have a strong potential to encourage innovation may significantly reduce the overall cost in the longer term. Therefore, when thinking about ways to address climate change.
Adopt a long-term perspective based on innovation. Innovations such as compact nuclear reactors and carbon sequestration technologies could be a turning point in reducing net greenhouse gas emissions to zero at a low cost. And, of course, prediction is an order, “as the Danish physicist Niels Bohr says, because of the trajectory.” Very difficult, especially to predict the future of technology is not known, the most we can do is to predict the cost of achieving the net zero emissions target. However, we can plan ahead without regret by offering incentives to encourage the use of low-cost means to reduce greenhouse gas emissions and low Carbon innovations, such as adopting an economy-wide carbon pricing system, while making rational investments in new technologies.
reduction of greenhouse gas emissions is not enough to stop climate change: gases already emitted accumulate in the atmosphere and the phenomenon will continue for a long time, after 2100
according to the IPCC *.
Changing climatic conditions therefore imposes a new situation: infrastructures, current investments and human activities must take into account the future development of climate and allow you to gradually adapt to it
This is the top priority! To do this, we must limit our greenhouse gas emissions, especially those of CO2, as much as possible. Everyone has to get started!
Each of us can help limit greenhouse gas emissions: avoid waste, reduce energy consumption by insulating our home, equip ourselves with energy-efficient appliances, travel as little as possible by car, by scooter or plane, prefer local and seasonal fruits and vegetables …
For their part, the leaders discuss the future of the planet during international conferences, in particular during the Conferences of the Parties (COP). In their country, they must then find compromises between all the actors of society to fulfill the commitments they have made. Manufacturers have already improved their manufacturing processes to save energy and reduce the weight of raw materials and packaging. Some are developing less polluting products and eco-designed products in which all stages of the product’s life (from manufacture to disposal) are more environmentally friendly.
Cities are putting in place systems such as Urban Travel Plans. They facilitate travel by developing public transport, walking and cycling!
