The world’s clean air is becoming more and more difficult to achieve, as emissions of carbon dioxide and other pollutants from burning fossil fuel continue to grow.
As global emissions continue to increase, the question of what to do about air pollution is once again being debated.
This week, the UN released a report on air quality in the world’s major cities, and its main recommendations include the introduction of a national clean air strategy and stricter restrictions on industrial emissions, including new carbon taxes.
These new measures are part of the new Paris climate accord, which aims to limit global warming to 2C above pre-industrial levels.
But many climate campaigners have called for a new approach to tackling pollution in the countrys major cities.
While some countries, such as China, have adopted a zero-emission strategy, other cities such as New York have not.
The Paris Agreement calls for the emission of no more than 40 per cent of the worlds total annual emissions of greenhouse gases, and this is the target most developed countries have yet to reach.
According to data from the World Bank, the US has the lowest carbon intensity of any major economy, and China has the highest.
“The world needs a strategy to fight climate change that includes cutting emissions from transport and energy and making the investments necessary to meet the targets,” said Mark Sayer, Climate Action Tracker director.
However, the report also suggested that the world is not yet ready to go all-out on cleaning its air, and there are still major challenges to be overcome.
In particular, the study found that air quality is a big concern for people in many cities.
“The majority of people living in urban areas are affected by the impact of air pollution,” said Professor Michael Schott of the London School of Hygiene and Tropical Medicine.
For example, more than 50 per cent said they regularly use indoor air purifiers to limit their exposure to harmful particles, and more than 60 per cent reported breathing more than 20 times the legal limit for ozone, a greenhouse gas.
Professor Schott said that in many cases, the health consequences of air quality problems are difficult to detect, and that it is often difficult to measure in real time.
If we are to reduce pollution, we need to understand what’s happening in the real world, and how it affects people, he said.
Some cities have already set a goal to reduce their emissions by 30 per cent by 2030.
On the global level, the Paris Agreement says that emissions reductions should be achieved through voluntary measures such as carbon taxes, which are also used in many other countries.
So, is it feasible to achieve a 30 per of cut in emissions, without changing the way we live and work?
The new Paris Climate Agreement will likely include new carbon tax measures, but for now, Professor Schott is hopeful that the global community can work together to achieve the ambitious goal of reducing carbon emissions.
Although this sounds ambitious, it does mean that countries will be required to invest in the right infrastructure to meet this target, and it also means that countries have to meet other targets to reduce emissions.
But even if we could achieve the 30 per cut in CO2 emissions, it is unlikely that we would be able to completely eliminate pollution from the atmosphere.
Air pollution can also affect our health and wellbeing.
Research by the UN’s World Health Organization found that the levels of unhealthy air particles in the air can lead to respiratory illnesses, which can cause bronchitis, chronic obstructive pulmonary disease (COPD), lung cancer, and heart disease.
Other studies have also shown that air pollution can be harmful to our immune system.
We are also concerned about the impact air pollution has on our mental health.
“It is often very hard to quantify the impact and its impact on people’s mental health,” said Prof Schott.
When we consider the many health problems caused by pollution, it’s clear that tackling air pollution will require a global commitment.
