Vancouver releases plan to reduce embodied energy emissions
On November 17, 2020, the Vancouver Council approved the Climate Emergency Action Plan to reduce the city’s carbon pollution by 50 per cent by 2030. The plan is in alignment with the findings of the United Nations Intergovernmental Panel on Climate Change, calling for measures to limit global warming to 1.5°C.“Our plan builds on our previous climate plans and focuses on cutting carbon pollution from our biggest local sources – burning fossil fuels in our vehicles (39 percent) and in our buildings (54 percent),” says the City of Vancouver’s website.
In addressing the emissions from buildings, the City states that it aims to cut the carbon pollution from the operation of new and existing buildings in half by 2030, compared to 2007. This goal is achieved mainly by increasing buildings’ energy efficiency and switching to renewable energy.
The plan also sets embodied carbon targets for new buildings, based on a set of benchmarks established from existing buildings. This mandate—a first of its kind in North America—takes responsibility for carbon pollution created while extracting, manufacturing, assembling, replacing and disposing of building materials, such as concrete, metals, and insulation.
A third of the emissions from buildings and construction can be attributed to embodied carbon. By 2030, Vancouver will ensure 40 percent less embodied emissions from new buildings and construction projects compared to 2008.
The embodied carbon goals will be met by measures including:
- Using materials more efficiently
- Reusing existing buildings and materials
- Building more from sustainably sourced wood and mass timber
- Using lower-carbon blends of concrete
- Powering construction sites with renewable energy instead of diesel fuel
- Using low-carbon insulation instead of spray foam, and putting less parking in buildings
To reduce transportation emissions, the Plan sets the following targets for 2030:
- 90 percent of Vancouver citizens will live within an easy walk or roll of their daily needs
- Two-thirds of trips will be by active transportation and transit
- Half the kilometers driven on Vancouver’s roads will be by zero-emissions vehicles
“This plan means change. It means residents, businesses and the City doing our part to transition off fossil fuels. It is designed to make it easier for you to live a carbon-free life. We’ll continue to gather public input on the actions as we move forward to make this an effective and equitable climate plan,” says the City’s website.
