There are many low -cost and cost -effective ways to stop global warming

Solar energy prices have dropped by 85% in one year

Solar energy prices have dropped by 85% in one year.

Not only do we have the tools to reduce emissions and prevent global warming by 2030, but half of the carbon -cutting options available are less expensive and more cost -effective. according to UN experts.

There is no money bubble, but a mosaic of activities – from the development of solar and wind technology, to the global economy – recognized by the UN’s Intergovernmental Panel on Climate Change (IPCC) as low yield.

The IPCC says less than three years of age will stop global melting, and in less than ten years it will reduce them by 43 percent from 2019 levels. give us a shot at keeping global warming at 1.5 degrees Celsius.

But current policies support the use of fossil fuels and take the world in the wrong direction, the IPCC said, in a flagship report on fossil fuels. warming, published on Monday.

Despite the fixed time limit, the IPCC said the ability to cut carbon in all areas “is enough to reduce global emissions by half or less”.

While this requires action among a number of options, the report of low -volume measurements said “more than half of this could be available for all regions”.

“The market benefits of some options outweigh their cost,” he added.

Wind and sun

By 2019, it will be 59 billion tonnes, or gigatonnes, of CO.2 or similar to other cleaning gases.

The nature of the options is expected to reduce emissions by 31 to 44 gigatonnes by 2030.

There are four key areas where carbon reduction potential is highest between now and the end of the decade – solar and wind energy, deforestation, and with the restoration of forests and other ecosystems.

Of those, sun and wind are some of the lowest options available due to the sharp fall in the prices of these technologies – down 85 and 55 percent between 2010 and 2019, respectively. as shown.

This “shows that by strengthening sound policies and economic systems, climate change can be invested in a big and fast way,” said Michael Wilkins, head of at the Center for Climate Finance and Investment at Imperial College Business School.

It can be seen that more solar emissions can be seen by reducing emissions to between two and seven gigatonnes of CO.2 as of 2030. Wind speed can save between 2.1 and 5.6 gigatonnes.

Most of that is likely, according to the report, to have unhealthy costs of living because it is much cheaper than fossil fuels.

The reduction of methane in the production of fossil energy is also the lowest.

Other energy development options are overall low cost, with high cost, such as nuclear power and hydroelectricity.

Food and forests

Protecting and restoring natural areas is the second most important area to reduce CO.2 release.

Forests are important for transporting CO2 man -made activities, and the IPCC has found that reducing deforestation and deforestation can reduce net emissions by between three and nearly eight gigatonnes, e.g. mostly at a low price.

Restoration of these ecosystems would save one to five gigatonnes. But the work in this area is much more expensive than the level expected by the IPCC.

Switching to “sustainable” foods and reducing food waste could save more than two gigatonnes, the IPCC said, but did not offer a price because of the size. global diversity and lack of data.

‘Equal balance’

The car segment is noted for the fact that no single option has the potential to reduce emissions.

But close to what can be done – switching to public transport and trucks, the need for fuel in road vehicles, shipping and airports – comes at unfavorable prices.

In the construction industry, the reduction in energy demand and the efficiency of materials such as lighting is seen as low -cost options, albeit with limited efficiency.

The construction of the most energy -efficient buildings is much more expensive (between as little as one and more than two gigatonnes), while the costs are still at an all -time high.

In industry, of course, most of the options – rather than improving energy efficiency and cutting other gas emissions – involve higher costs.

However, the region has the potential to reduce emissions, which means switching to carbon-intensive energy sources.

“The costs of climate protection are very high when viewed at the global level and across generations,” said Elmar Kriegler, of the Potsdam Institute for Climate Impact Research, one of the IPCC authors.

But, he said, costs vary from country to country, with developing countries facing higher costs of moving away from fossil fuels.

“That’s why equity is so important, not just in one country but all over the world.
