Canada has announced new goals to greenhouse gas emissions to thirty percent below 2005 levels by 2030. The announcement has received criticism for not addressing the oil sands in Alberta. The pledge comes just prior to a meeting between the Canadian provinces in June and a major climate change conference in Paris in December. The pledge was formally submitted to United Nations Framework Convention on Climate Change on Friday.
Legislation introduced by New York City Councilman Donovan Richards (D-Queens) would prohibit the exterior and interior lighting at night for roughly 40,000 buildings. The bill is a part of the city’s plan to reduce greenhouse gas emissions by 80 percent by 2050. Decreased lighting usage is of particular interest to meet this goal as 70 percent of New York’s carbon emissions come from buildings in the city. The bill states that a $1000 fine will be issued for non-compliance.
Australia is required to reduce by 30% the emissions of carbon dioxide by 2025. The decision was made in the context of the World Conference on climate change, which took place in Paris with the participation of all the developed countries.
Some of the world’s largest cities could face temperatures up to 8°C higher than those of today, because of the combination of increased greenhouse gas emissions and the ‘urban heat island’ effect, as cement and asphalt amplify the impact of climate change.
