BC Ferries urged to chart a new course around LNG

"...“The new ships are a step in the right direction, but when it comes to the transition to fully electric vessels — later is too late,” Barford said. The ferry service needs to wean itself off fossil fuels, and especially liquified natural gas (LNG), and electrify the fleet faster to achieve 2030 emissions target, according to Stand. earth’s new Fracked Ferries report released Tuesday..."

New emissions targets may sink LNGs pitch as a shipping fuel

"...The new accounting method means LNG can no longer sail under the radar when it comes to emissions, said Elissama Menezes, global campaign director for the Say No to LNG coalition. “It’s a huge step and quite exciting to see,” Menezes told Canada’s National Observer. What people are reading Canada’s Conservatives are courting constitutional chaos By Max Fawcett | Opinion, Politics | July 11th 2023 “At the end of the day, it really brings some accountability to the shipping sector, which for too many years has not really been responsible for the whole footprint of its emissions..."

Montreal fireworks cancelled over wildfire smoke

"...Dr. David Kaiser, deputy medical director of Montreal's public health department, said a 2022 report on the city's air quality indicated that fireworks displays can lead to concentrations of air pollutants — known as fine particulate matter — of 300 particles per cubic metre, a level considered very unhealthy. "There is a measurable impact that lasts for a few hours and that touches mostly the neighbourhoods that are surrounding the fireworks show," he told reporters alongside Émond, adding that those areas have some of the worst air quality in the city at normal times, due to vehicle traffic and industrial sites..."

Quebec launches North Americas largest electric bus project to lead the way for climate-friendly transit

"...There are roughly 2,000 buses operating in Metro Vancouver, where 35 per cent of emissions come from road transportation. The province requires 50 per cent of new bus purchases between 2026 and 2028 to be zero-emission buses, with 100 per cent of purchases being emission-free starting in 2029 and beyond, said Murray Sinclair, public affairs officer for B.
