City's path to 'net zero' emissions by 2050 to cost billions

City staff calculate it will cost more than$30 billion in today's dollars to hit Ottawa's targets forreducing greenhouse gas emissions by 2050, but they also say the savings will more than offset that daunting price tag.

The figure "jumps off the page" in a new report headed to thestanding committee on environmental protection, water and waste management on Tuesday, admitted Coun. Scott Moffatt, who chairs the committee.

• Net-zero emissions plan a pipe dream without funding help, chair says
• Ottawa's weather to get warmer, wetter and wilder: study

The idea is not that the cost would be borne by the municipality, but that upper levels of government and the private sector would do their part over many years, he said. Moffatt gave the example that hepersonallyneeds the automotive industry to shift before he canbuy an electric vehicle to drive from rural North Gower to city hall.

Council last year declared a climate emergency, and in January seta more ambitious target for reducing greenhouse gas emissions. Moffattsaid he sees it as his job to make sure Ottawa is "serious" about that goal.

"Municipalities across the country, across North America, have passed the motion. They make the commitment. I've yet to see anyone actually monetize it or say what needs to happen to get there.So we've done that," said Moffatt.

Report sees savings by 2032

The new target calls for the wider community to eventually reduce emissions so that 30 years from now they are100 per cent below 2012 levels, or "net zero."

Getting there would take major retrofits of buildings and homes, and a rethink of how they're heated and cooled. It would also require congestion charges and car-free zones, and would assume all new vehicles are electric.

• City's climate plan calls for smaller homes, cleaner cars

After four years of work on what's known as the city's"energy evolution" plan, staff have now produced a final strategy and calculated such a vision would cost $57.4 billion, or $31.8 billion in today's dollars.

But the savings of those more efficient buildings and electric cars would start to offset the costs by 2032, staff report, so that by 2050, Ottawa as a wholewould have saved $28.4 billion, or $2.7 billion in 2020 dollars.

Local economy can managethe shift

City staff acknowledge the strategycomes with many risks, from lack of government or private fundingto limited uptake by residents and industry, and even competing city council priorities.

But experts say the cost itself is realistic, given the much larger size of Ottawa's economy, and the fact the changes would roll out over three decades.

Nicholas Rivers, the Canada Research Chair in Climate and Energy Policy at the University of Ottawa, has seen many climate change plans at the national and international levels, but says he has yet to see a city-level price tag for hitting greenhouse gas emissions targets.

Such expenditures would be justified, he said, and the costs of climate change and doing nothing would be much greater.

"It's not fair to look at one side of the ledger," Rivers said.

Ralph Torrieagreed. He's a seniorassociate with the firm that worked with Ottawa on its strategy, and an adviser for Low Carbon Cities Canada, of which Ottawa is a member.

"It is a big job, but the Canadian economy is capable of making this transition," he wrote in an email."With interest rates down and the economy in need of a reset, this is the time to go all-in for a green recovery."

As for the coming five years, city staff have come up with a list of 20 projectsto tackle such as making sure energy priorities form part of Ottawa's new official plan, and working on programs to encourage building retrofits.
