中国温室气体排放总量可望2025年出现拐点

北欧绿色邮报报道(记者陈雪霏)根据伦敦经济学院(LSE)下属的两所研究院6月8日公布的一项研究结果显示,按照目前的趋势,中国的温室气体排放量可能将于2025年达到峰值,即125-140亿吨,比中国自己预期的要提前五年。

中国自己预计是到2030年才能达到峰值,然后下降,这也是2013年北京出现严重雾霾时有关专家说的治理需要18年的说法。

但伦敦经济学院研究者在一项声明中称,”这项研究显示,世界将更有可能避免全球变暖超过工业化前平均气温2摄氏度以上。”

报告撰写人是著名的气候经济学家尼可拉斯·斯泰恩(Nicholas Stern)和分析家菲尔古斯·格林(Fergus Green)。

“从对主要排放领域的分析中我们得出结论,中国的温室气体排放很可能不会等到2030年达到峰值,而是很可能到2025年就已达到峰值。甚至还可能更早。”  声明说。

报告指出,中国的煤炭消费2014年和2015年第一季度都出现下降,此前多年里,中国的煤炭消费一直增长,导致城市出现严重的空气污染以及大量温室气体排放。研究者通过计算得出结论,中国的煤炭用量已经达到”结构性的最大值”,今后5年里将维持这样的水平,而天然气用量将迅速上升。导致这一变化的原因是中国经济的结构性调整以及政策上更重视可持续发展、减少对环境的破坏。

中国对全球减排至关重要

空气污染已经成为中国最大的挑战之一

从本周一至周五,联合国成员国代表正在德国波恩就全球气候协议展开讨论,为今年底巴黎全球气候大会签署协议做准备。新的气候协议将于2020年开始生效,目标是将全球气候变暖控制在2摄氏度之内。

按照联合国政府间气候变化专门委员会的要求,要达到这一目标,至2050年,全球每年必须在2010年的基础上减少40-70%的温室气体排放。

报告认为,全球是否能在2020年或之后达到将气温升高控制在2摄氏度的目标,关键取决于中国减排的速度和能力。

格林表示,目前全球的温室气体排放约为500亿吨二氧化碳当量,中国约占四分之一。

此间舆论认为,该报告结果表明,中国政府过去一年采取的严厉措施,确实减少了煤炭的使用,对减少温室气体排放起到了切实效果。原来所说的18年,也有望缩短到13年甚至更短。凡事有惯性,一旦形成良性循环,中国环境在10年内出现巨大改善也不是不可能的。 当然,这需要政府,企业,社会和全中国人民齐心协力的共同努力。

China Headlines: Beijing holds breath for effective smoking ban

China Headlines: Beijing holds breath for effective smoking ban

BEIJING, June 1 (Greenpost) — A downtown hotpot restaurant was the first business to get an official warning for breaking Beijing’s toughened smoking ban, as inspectors swooped to enforce the new regulation on Monday.

On the first day of the ban, which prohibits smoking in all indoor public places, workplaces, and on public transport, authorities sent more than 1,000 inspectors to government agencies, hospitals, schools, hotels, restaurants and entertainment venues to ensure it is being followed.

The inspectors found cigarette butts in the hotpot restaurant’s washroom on Monday morning, with the restaurant also failing to publicize the smoking complaint hotline 12320 on its no-smoking posters.

Inspectors said they will visit again in two days to check the restaurant’s compliance, and warned of a fine up to 100,000 yuan (1,614 U.S. dollars) if it fails to comply.

The new ban was passed by Beijing’s municipal legislature in November. Individuals caught smoking in public places may be fined 200 yuan (32 U.S. dollars), while businesses will have to pay up to 100,000 for failing to discourage smoking on their premises.

As the world’s largest tobacco maker and consumer, China has more than 300 million smokers, almost the size of the U.S. population, and another 740 million people are exposed to second-hand smoke each year.

Ma Yongsheng, who runs a restaurant in Beijing, canceled a wedding banquet reservation on Monday, as a guest insisted on smoking during the meal.

“If we continue to host guests who smoke, we’ll surely be fined,” Ma said.

At Beijing Capital International Airport, people gathered at two designated outdoor smoking areas to have a last puff as indoor smoking rooms in the airport’s three terminals have all been closed.

While regulators has vowed strict implementation, some still doubt the feasibility of the new ban and fear authorities’ resolve to curb smoking could taper over time and leave the ban as ineffective as its predecessors.

Beijing has had smoking bans in place since as far back as the 1990s, and stepped up the campaign before the 2008 Olympics, but the bans have always been weakly enforced.

A Xinhua reporter spotted people smoking indoors in a downtown hospital on Monday.

“I hope the government’s momentum to curb smoking can last this time,” said someone with the screen name “@skywalker” on microblog Sina Weibo. “Just don’t let this ban become another barely-enforced policy nobody remembers after six months.”

At a bus stop during the morning rush hour, a volunteer asked scores of people to finish smoking elsewhere before lining up.

“Most stub out their cigarettes at our request but that’s the most we can do,” the volunteer said. “We are not authorized to fine those who refuse to obey the ban.”

The World Health Organization (WHO) suggested mobilizing the public to help enforce the ban.

“If you see someone smoking in a restaurant, tell them to stop! Talk to the manager or owner, or call the national health hotline 12320 to complain,” said WHO China Representative Bernhard Schwartlander.

China signed the WHO Framework Convention on Tobacco Control (FCTC) in 2003.

“Beijing’s ban on smoking indoors is consistent with China’s commitment to the FCTC of protecting the health of non-smokers through enhanced legal support,” said Wang Qingbin, a professor with China University of Political Science and Law who helped draft the new smoking ban.

The new ban also serves as a test case for a similar move nationwide. Draft legislation for a national ban has been published to solicit public opinions.

In April, China’s top legislature adopted an amendment to the Advertisement Law, banning tobacco advertising in mass media, in public places, public vehicles and outdoors.

China also raised consumption tax on cigarettes at the wholesale level on May 10, a move expected to cut cigarette consumption by 4 to 5 percent and add 100 billion yuan to annual tax revenue.

Data from local price monitoring departments across the country shows the tax rise has largely been passed on to consumers. Cigarettes priced under 20 yuan per pack have seen a price hike of between 0.5 and one yuan. Those priced above 20 yuan have generally been subject to a price rise of around two yuan.

Angela Pratta, who leads the WHO’s Tobacco Free Initiative in China, has urged the government to lead by example in enforcing the ban.

“Strong enforcement is critical to ensuring the effectiveness of smoke-free laws, so too is leadership. Senior officials and leaders in government offices need to lead the way by setting an example and supporting enforcement efforts,” Pratta said. Enditem

瑞典北极光令人震撼

瑞典北极光令人震撼

北欧绿色邮报报道(记者陈雪霏)--今年是北极光频发的年份。3月17日,记者正好在看极光最好的位置,基律纳。

瑞典太空研究所所长亲切地接受了记者的采访。他认为,无论如何,人类对太空的认识还是非常有限的,因此需要进一步深入研究观察。他的研究所地理位置优越,正好处在人烟极其稀少的地方。这里天空中的各种现象观察清楚,发射卫星也容易。因此这里也是卫星发射试验基地。
针对天气极光现象,他说虽然现在是太阳活动频率下降的时候,但是,也有可能发生极光,而且各种色彩都不同。不过,一般美的东西,往往是有毒的。因此需要认真研究。下面就请欣赏极光吧!

北欧绿色邮报报道(记者陈雪霏)--河北省石家庄中雅房地产代表团11月6日访问了瑞典最宜居的城市恩雪平。

此间,李立景等三名代表团成员听取了恩雪平市政水务官员哈尔贝

的介绍。恩雪平号称是瑞典最中心的城市,尽管只有4万人,但她

周围却是首都斯德哥尔摩,乌普萨拉和维斯特罗斯。周边聚集着瑞典60%的人口的大公司,因此,这里的地理位置十分优越。

恩雪平以其优美的环境和合理的布局,成为舒适的宜居城市。

他们用天然的方法治理雨水污染的办法事半功倍,一次投资,一劳永逸。处理后的水如图所示非常清凉。

市中心的小花园使这个小城市显得非常漂亮。IMG_5182
