China Focus: Clean heating powers China's green development endeavor******

HARBIN, Nov. 1 (Xinhua) -- Winter in north China used to herald smoggy skies and suffocating air quality due to the extensive burning of coal for heating. Nowadays, with the widespread adoption of renewable energy, the situation has changed drastically.。

Centralized winter heating has kicked in ahead of schedule in many northern regions in response to continued low temperatures. On Monday, Tianjin Municipality and Hebei Province started off winter heating. Beijing began debugging the city's heating system in late October and will officially start heating service according to weather conditions.。

"The heating system in our residential quarter makes use of heat from wastewater instead of burning coal," said Li Shifu, a resident of Harbin, capital of northeast China's Heilongjiang Province.。

The sewage heating system has been developed by KINT, a Harbin-based clean energy enterprise. It has provided sewage heating for more than 80 million square meters of building space in dozens of Chinese cities. Compared with coal-powered heating, the system reduces the emission of pollutants such as carbon dioxide and sulfur dioxide by more than 4.7 million tonnes every year.。

"We extract and utilize heat energy from the waste. There is no foul smell in radiators," said Li Jinfeng, who works at KINT.。

Clean and renewable energy is part of China's efforts in striving toward a low carbon economy.。

China will make further efforts to promote clean heating and ensure that clean energy is used for heating in more than 70 percent of the households in northern China. The use of clean heating in the southern part of the country will also be explored, stated a guideline issued by the National Energy Administration in April.。

Data from the China Association of Building Energy Efficiency showed that by the end of 2020, there were 8,200 enterprises engaged in businesses related to clean heating in China, with a total output value of 900 billion yuan (about 140 billion U.S. dollars) and more than 1.19 million employees.。

In Huaibei, a major coal-producing base in east China's Anhui Province, ground source heat pumps, which extract heat from the ground, are being used to substitute coal-powered electricity.。

In a residential quarter alone, such pumps are expected to help reduce carbon dioxide emissions by 32,000 tonnes, sulfur dioxide emissions by 217 tonnes, nitrogen oxides emissions by 205 tonnes and soot emissions by 127 tonnes every year.。

Hongtong Heating is responsible for offering heating services to more than 100 residential quarters in Harbin. On Oct. 26, the company's second phase of biomass power generation project began operations, which is expected to make use of about 600,000 tonnes of agricultural and forestry waste every year.。

"The price of biomass fuel is about 300 yuan per tonne, less than one-third of the current coal price," said Li Jianwei with the company. Enditem。

World leaders gather in Glasgow for make******


Police officers patrol Glasgow Green near the Scottish Event Centre in Glasgow, Scotland, on Saturday, ahead of the United Nations COP26 climate summit.。

World leaders began descending on the Scottish city of Glasgow yesterday for the United Nations COP26 summit, billed as a make-or-break chance to save the planet from the most calamitous effects of climate change.。

Delayed by a year due to the COVID-19 pandemic, COP26 aims to keep alive a target of capping global warming at 1.5 degrees Celsius above pre-industrial levels – the limit scientists say would avoid its most deadly consequences.。

Meeting that goal, agreed in Paris to much fanfare in 2015, will require a surge in political momentum and diplomatic heavy-lifting to make up for the insufficient action and empty pledges that have characterized much of global climate politics.。

The conference needs to secure more ambitious pledges to further cut emissions, lock in billions in climate finance, and finish the rules to execute the Paris Agreement with the unanimous nod of the nearly 200 countries that signed it.。

"Let's be clear – there is a serious risk that Glasgow will not deliver," UN Secretary General Antonio Guterres told leaders of the Group of 20 rich nations last week. "Even if recent pledges were clear and credible – and there are serious questions about some of them – we are still careening towards climate catastrophe."

The existing pledges to cut emissions would see the planet's average temperature rise 2.7 degrees this century, which the UN says would supercharge the destruction that climate change is already causing by intensifying storms, exposing more people to deadly heat and floods, killing coral reefs and destroying natural habitats.。

The signals ahead of COP26 have been mixed. A new pledge last week from China, the world's biggest polluter, was labelled a missed opportunity that will cast a shadow over the two-week summit. Announcements from Russia and Saudi Arabia were also lackluster.。

The return of the United States, the world's biggest economy, to UN climate talks will be a boon to the conference, after a four-year absence under president Donald Trump.。

But like many world leaders, President Joe Biden will arrive at COP26 without firm legislation in place to deliver his own climate pledge as Congress argues over how to finance it and new uncertainty about whether US agencies can even regulate greenhouse gas emissions.。

Leaders of the G20 meeting in Rome this weekend will say they aim to cap global warming at 1.5 degrees, but will largely avoid firm commitments, according to a draft statement.。

The joint statement reflects tough negotiations, but details few concrete actions to limit carbon emissions.。

The G20, which includes Brazil, China, India, Germany and the US, accounts for about 80 percent of global greenhouse gas emissions, but hopes the Rome meeting might pave the way to success in Scotland have dimmed considerably.。

Adding to the challenging geopolitical backdrop, a global energy crunch has prompted China to turn to highly polluting coal to avert power scarcity, and left Europe seeking more gas, another fossil fuel.。

Ultimately, negotiations will boil down to questions of fairness and trust between rich countries whose greenhouse gas emissions caused climate change, and poor countries being asked to de-carbonize their economies with insufficient financial support.。

COVID-19 has exacerbated the divide between rich and poor. A lack of vaccines and travel curbs mean some representatives from the poorest countries cannot attend.。

COVID-19 will make this UN climate conference different from any other, as 25,000 delegates from governments, companies, civil society, indigenous peoples, and the media will fill the event venue.。

World leaders will kick start COP26 today with two days of speeches that could include some new emissions-cutting pledges, before technical negotiators lock horns over the Paris accord rules. Any deal is likely to be struck hours or even days after the event's November 12 finish date.。
