cleaner cooking solutions can save millions of lives, but far more investment is needed

This week is the June 5 comesWorld Environment Day, and this year\'s focus is on the vital topic of air pollution, which causes premature deaths of 7 to 8 million people around the world each year.
The cost of overall air pollution is staggering.
More than 90% people around the world cannot breathe clean air.
Air pollution costs the global economy $5 trillion a year. Ground-
By 2030, ozone pollution levels are expected to reduce production of major crops by 26%, which is alarming, more than half the annual death toll from air pollution, up to 4 million people a year. Indoor air pollution is caused by wood, charcoal, coal, feces or kerosene.
Even today, however, more than 3 billion people around the world use these dangerous fuels for cooking.
Exposure to indoor air pollution by cooking with these fuels is a major factor in children\'s pneumonia, chronic pulmonary disease, heart disease, stroke, and lung cancer.
When pregnant women face domestic air pollution due to cooking, their risk of stillbirth, low birth weight and decreased lung function increases.
Every year, 400,000 children under the age of 5 die from domestic air pollution.
Even in all outdoor air pollution, 12% comes from indoors or in the home, mainly cooking.
In fact, the data may underestimate the role of indoor air pollution.
A new study last week found that in India, indoor air pollution caused by cooking and heating is the main single source of outdoor pollution, accounting for 1-quarter to one-
Third, environmental air pollution.
In India alone, more than 800,000 people die prematurely each year from indoor air pollution.
In addition, the black carbon soot produced by cooking is the main cause of black carbon pollution and is itself the main factor causing climate change.
But the news is not all bad news.
We know how to make cooking cleaner and safer.
A report by the clean cooking alliance this year on the clean cooking technology industry found that progress is being made in the sustainable private sector
According to information provided by more than 40 cleaning cooking companies from 2015 to 2017, the led industry.
But the overall downturn in investment continues to drag the industry.
The clean cooking Alliance found that the total amount of financing in 2017 accounted for only about 1% of the $4 billion needed to achieve universal clean cooking in 2030.
Although the report clearly states that some emerging companies are achieving financial sustainability on a large scale, it is clear that the clean cooking challenge needs to create incentives for large-scale private sector investment solutions.
There are many cleaner options-
Including biogas, charcoal, ethanol, kerosene, liquefied petroleum gas, natural gas, biomass particles and coal balls, electricity and solar energy--
If they reach the end user
Some countries are expanding the supply of clean electricity through microcomputers
Grid, distributed resources like villages
Expand the scale of solar, wind and biofuels by using government procurement, as well as significant advances in energy efficiency.
A successful example is to subsidize poor households to access cleaning services.
Burn fuel like India does with liquefied petroleum gas (LPG).
The Indian government has effectively lowered the entry threshold for domestic LPG users by sending cash transfers directly to consumers\' bank accounts, while ensuring that commercial users continue to pay market prices.
In the past two years, about 50 million households have been linked to liquefied petroleum gas, and the government hopes to add another 30 million households by March 2020.
Another way is for companies to provide more efficient and cleaner services to consumers.
Burn the stove for free or below cost, while hoping to make a profit by selling dedicated fuels such as concentrated sawdust particles.
The wide application of technology and mobile phones has also opened up new options for energy access.
For example, the \"pay side\" model allows consumers to pay in mobile currency only for the fuel they use, without having to save money for the entire LPG cylinder.
With the successful transition to clean stoves and fuels, studies have shown that the duration of severe pneumonia and respiratory infections in young children is significantly reduced, blood pressure in pregnant women is reduced, birth weight increases, and gestational age increases during childbirth.
Long-term efforts are needed to achieve these positive health outcomes.
Get high for a long time
High quality stoves and fuels;
Consumer education promotes the continuous use of new technologies and policies to increase the availability and affordability of clean stoves and fuels.
Improving the health and life of nearly half the world\'s people is at stake.
When we celebrate World Environment Day with a meal, we must remember that billions of people lack clean cooking opportunities and millions die prematurely.
Clean cooking is probably the least invested environmental and health problem in the world.
Global leaders and ordinary citizens must all support more efforts and invest more in many clean cooking solutions that can now save millions of lives.
