william van geest, interim executive director of ecology ottawa, was among the speakers urging the city to ramp up efforts to plant more trees.
“trees are one of our best defences against climate change, whether for mitigation or resilience, and the return on investment is almost unbeatable,” he said.
paul tulloch, a data scientist who studies methane mitigation across the world, said ottawa had invested in its green bin program to divert organic matter from landfills. that’s a great step forward, but the program is under-utilized.
“we’ve looked at countries like germany and japan, where organic diversion is almost part of their culture. there’s a culture change that needs to be addressed, not just hardware and capital costs,” he said. “i recommend, at least, an action plan to look at accelerating green bin usage.”
capital ward coun. shawn menard, the chair of the committee, said many of the data questions were due to be answered in the coming months, including an emissions inventory and updates on the climate change master plan and city’s tree canopy.
“you’re absolutely right,” menard told johnson. “we’ve seen this shrinking canopy in our city, and it’s certainly alarming and something we’re working to mitigate, not just through replanting, but keeping more trees.”
