巴黎限制汽车显著改善了空气质量
#地球

过去二十年,巴黎经历了一场大改造:汽车干道变成了自行车道,绿地增加,取消了 50,000 个停车位。跟踪巴黎空气质量的独立组织 Airparif 报告,自 2005 年以来,PM 2.5 水平下降了 55%,二氧化氮水平下降了 50%。 二氧化氮是由化石燃料燃烧产生的,20 年前巴黎几乎每个社区的二氧化氮水平都超过了欧盟的限值。到 2023 年,高水平二氧化氮地区只限于最繁忙的道路和高速公路。上个月,巴黎居民在公投中投票决定将另外 500 条街道移交给行人。一年前,巴黎大幅提高了 SUV 停车费,迫使司机支付比小型汽车多三倍的费用。巴黎还将塞纳河沿岸从繁忙的主干道变成了步行区,禁止大部分汽车驶入瑞弗里大道 (rue de rivoli)购物大道。

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.

The Singapore stock market has alternated between positive and negative finishes through the last five trading days since the end of the two-day winning streak in which it had added more than a dozen points or 0.4 percent. The Straits Times Index now sits just above the 3,060-point plateau and it's likely to see a narrow trading range on Monday.
