Canada's Air: Strategies For Pollution Reduction

Air pollution is a pressing issue in Canada, with far-reaching consequences for human health, the environment, and the economy. The problem is driven by a range of factors, including population growth, economic expansion, and the continued reliance on fossil fuels. To reduce air pollution, the Government of Canada has implemented various measures, including regulations, incentives, and investments in cleaner technologies. Additionally, individuals and communities can play a crucial role in improving air quality by adopting more sustainable practices, such as using public transportation, reducing energy consumption, and supporting renewable energy sources. Addressing air pollution requires a collective effort and is essential to safeguard the health and well-being of Canadians and protect the environment.

Reduce emissions by using public transport, walking, carpooling, or riding a bike

Canada is taking steps to reduce air pollution and fight climate change by establishing national air quality standards, investing in cleaner technologies, and implementing regulations. The Government of Canada is also committed to protecting Canadians from the adverse health effects of air pollution, including wildfire smoke, through various initiatives and funding.

One of the most effective ways to reduce emissions and improve air quality is to shift from private cars to public transportation. Transportation is the largest source of carbon emissions, and in many cities, personal automobiles are the single greatest polluters. By choosing public transportation, such as buses or trains, individuals can reduce their carbon footprint significantly. For example, switching from a car to public transportation can reduce up to 2.2 tons of carbon emissions annually per person. Additionally, public transportation reduces CO2 emissions by 45% compared to driving, leading to improved air quality and healthier communities.

Walking and biking are also excellent ways to reduce emissions and improve air quality. These modes of transportation are naturally the least carbon-intensive, and increasing their use can have a substantial impact. For example, even moderate increases in bicycle use can save an estimated 6 to 14 million tons of carbon emissions annually. Canada's Active Transportation Fund promotes the use of human-powered activities, such as walking and cycling, and invests in projects that encourage their use, ultimately reducing emissions and providing tangible benefits to communities.

Carpooling is another effective strategy to reduce emissions. If commuters carpooled 20 days a month, driving costs would decrease by 40-50%, and there would be less wear and tear on individual cars. Car-sharing programs, such as Flexcar and ZipCar, also offer low-emission or hybrid car options, reducing the number of cars on the road and the need for manufacturing new vehicles.

By implementing these changes, Canadians can play a crucial role in reducing emissions, improving air quality, and creating a healthier and more sustainable future for themselves and their communities.

Improve fuel efficiency and buy fuel-efficient vehicles

Motor vehicles are a major contributor to air pollution, especially in large urban areas with heavy traffic. In Canada, nearly 2 million new light-duty vehicles (LDVs) were sold in 2019, with an average fuel consumption of 8.6 litres of gasoline equivalent (Lge/ 100 km), higher than all other major LDV markets. This high consumption is partly due to the growing popularity of SUVs and pick-up trucks, which now make up 67% of LDV sales.

To improve fuel efficiency and reduce air pollution, Canadians can adopt fuel-efficient driving techniques. These techniques can lower a vehicle's fuel consumption and carbon dioxide emissions by up to 25%. Here are some ways to achieve this:

• Gentle acceleration: Ease onto the accelerator gently to use less fuel. Take 5 seconds to accelerate to 20 km/h from a stop.
• Steady speed: Maintain a consistent speed to reduce fuel usage. Varying your speed between 75 and 85 km/h every 18 seconds can increase fuel consumption by 20%. Using cruise control on highways can help maintain a steady speed.
• Anticipate traffic: Keep a safe distance from the vehicle ahead and anticipate pedestrian and vehicle movements to maintain a steady speed and use less fuel.
• Avoid high speeds: Most vehicles are most fuel-efficient when travelling between 50 and 80 km/h. Above this range, fuel consumption increases with speed.
• Coast to decelerate: Instead of braking, take your foot off the accelerator and coast to slow down, conserving fuel.
• Avoid idling: Turn off your engine when stopped for over 60 seconds, except in traffic. Idling wastes fuel and increases emissions.
• Proper tire maintenance: Check your tire pressure monthly. Under-inflated tires increase fuel consumption and reduce tire life.
• Remove unnecessary weight: Take out items like salt, sand, and sports equipment. Lighter vehicles consume less fuel.
• Aerodynamic considerations: Remove roof or bicycle racks when not in use. Aerodynamic drag from these racks can increase fuel consumption by up to 20% on highways.
• Reduce air conditioning use: Air conditioning can increase fuel consumption. Open windows in the city, and use the flow-through ventilation system on highways.

In addition to these driving techniques, Canadians can also consider purchasing a fuel-efficient vehicle. Hybrid, electric, and plug-in vehicles are becoming more popular, and the Canadian government provides incentives for the purchase of zero-emission vehicles. The EnerGuide label, found on all new light-duty vehicles, provides information on fuel consumption, fuel type, and vehicle emissions, helping consumers make informed choices.

Reduce energy use by making homes more energy-efficient

The Canadian government has acknowledged that buildings, including homes, account for 13% of the country's greenhouse gas emissions, with this figure rising to 18% when space and water heating, electricity use for cooling, lighting, and appliances are taken into account. As such, the government has committed to helping Canadians make their homes more energy efficient, thereby reducing their energy bills and making their lives more affordable and environmentally friendly.

The Canada Greener Homes Grant, launched by Prime Minister Justin Trudeau, is a key initiative in this effort. The grant provides up to $5,000 to Canadian homeowners for energy-efficient retrofits to their primary residences and up to $600 for home energy evaluations. Eligible improvements include replacing windows and doors, adding insulation, sealing air leaks, upgrading heating and cooling systems, and adopting renewable energy sources like solar panels.

Beyond government initiatives, Canadians can take several steps to make their homes more energy efficient. Firstly, it is important to view your home as a system where all elements interact. For example, sealing air leaks may require subsequent changes to ventilation. Secondly, when purchasing major appliances and heating or cooling equipment, consult the EnerGuide labels, which indicate the energy performance rating of a product based on Canada's Energy Efficiency Regulations. Thirdly, consider getting an EnerGuide home evaluation by an energy advisor, who can provide insights into your home's energy performance and suggest renovation options.

Additionally, simple actions such as turning off lights and electrical items when not in use, unplugging rarely used devices, and using smart power bars can significantly reduce energy consumption and associated costs.

Limit the use of wood-burning appliances and fossil fuels for home heating

In Canada, much of the home heating is produced by burning fossil fuels such as coal, gas, and oil, or wood. Using less energy for home heating and reducing your use of electricity will help clean the air. Here are some ways to limit the use of wood-burning appliances and fossil fuels for home heating:

Use a Heat Pump Instead of a Furnace

Many people in Canada rely on fossil fuels to heat their homes, which creates a lot of emissions, mostly from natural gas. Natural gas is largely composed of methane, a potent greenhouse gas and major contributor to climate change. By switching to electric heating, most Canadians can significantly decrease their emissions at home. Heat pumps are energy efficient and a great climate solution. They also save money and work in cold weather.

Replace Your Gas Water Heater with a Heat Pump Water Heater

Water heaters are the second most energy-intensive appliance in the home, after space heaters. In Canada, water heaters account for nearly 20% of the energy used in the average house and 21% of residential greenhouse gas emissions. By heating your water with electricity rather than fossil fuels, you can drastically lower your emissions. Heat pump water heaters are also eligible for rebates, and they will save you money in the long run.

Trade Your Gas Stove for an Induction Stove

Gas stoves emit harmful pollutants like nitrogen dioxide, which can cause respiratory issues, especially in children with asthma, as well as heart disease and other illnesses. An induction stove is a healthier, more climate-friendly alternative to gas. An induction stove uses magnetic induction to heat a pot or pan, whereas a gas stove uses thermal induction. Induction stoves are also far more energy efficient than traditional electric and gas stoves.

Replace Your Gas Fireplace with an Electric One

Wood-burning fireplaces release dangerous toxins, but gas fireplaces are not a safe alternative. Ventless fireplaces send combusted air, which can include pollutants like carbon dioxide and nitrogen dioxide, directly into your living space. An electric fireplace will make your home look cosy without burning wood or fossil fuels. If you have a heat pump, you can use that to heat your home instead.

Use Your Wood-Burning Appliance Properly

If you must use a wood-burning appliance, make sure to use it properly to reduce emissions. Only use your wood-heating appliance when necessary, and keep alert for warnings of winter smog in your area. Make a small hot fire with dry, clean wood, and use hardwoods such as oak, maple, or birch instead of softwoods. Comply with regulations prohibiting the burning of materials such as plastic, treated wood, or painted wood in domestic heating appliances.

Plant trees and vegetation to improve air quality and increase biodiversity

Planting Trees and Vegetation to Improve Air Quality and Increase Biodiversity

Planting trees and vegetation is an effective strategy for improving air quality and reducing air pollution in Canada. Trees act as a natural air filtration system, absorbing carbon dioxide and releasing clean oxygen for us to breathe. Additionally, they help to reduce air temperatures, which can lower the need for energy-intensive air conditioning and further reduce greenhouse gas emissions.

When it comes to selecting the right trees for air pollution reduction, not all trees are created equal. Some trees, like maple, are particularly effective at trapping air pollution particles. Coniferous trees, such as pines and cypresses, are excellent natural air purifiers due to their dense needle-like leaves that effectively trap pollutants. Their evergreen nature also makes them ideal year-round filters. However, their sensitivity to salt levels in the soil and their potential to block sunlight from reaching the ground need to be considered.

To maximize the impact of tree planting, it is crucial to plant the right trees in the right places. Trees should be strategically planted close to pollution sources, and the wind direction and landscape structure should be taken into account to ensure effective pollution dispersion. Additionally, a diverse range of tree species should be planted to enhance biodiversity and ensure the long-term resilience of the ecosystem.

Beyond trees, other vegetation can also play a role in improving air quality. Plants with hairy leaves, such as silver birch, yew, and elder, are particularly effective at trapping and reducing particulate matter. When planning urban green spaces, a mix of trees and other vegetation can create a diverse and resilient ecosystem that improves air quality and provides habitats for wildlife.

By planting the right trees and vegetation in the right places, communities can improve air quality, enhance biodiversity, and create healthier and more sustainable urban environments for people and wildlife to thrive.
