The main CAUSE of climate change is carbon emmissions produced from human activities (e.g. driving cars, builing houses) which adds to the greenhouse effect, trapping heat and further warming the Earth's surface. Canada has commited to keep global warming to below an increase of 2 degrees celcius (relative to preindustrial levels).LEARN MORE
British Columbia has commited to reducing its carbon emmissions to:
33% below 2007 levels by 2020
70% below 2007 levels by 2050
More Floods & Droughts
Hotter, drier, summers & more intense rainstorms will cause more severe and frequent floods and droughts.
Rising Sea Level
Estimated increase of sea level in coastal BC by 2100 is 1m or more. We will lose homes, communities, and ecosystems (an estimated total damage $30 billion by 2050).
The urban forest includes a variety of vegetation and landscape types such as parks, streetscapes, natural areas, and
private yards, which together form a complex system of urban greenery.
A healthy urban forest will be vital in a hotter, unpredictable future to protect human health during heatwaves, reduce our reliance on air conditoning, reduce flooding, absorb carbon, and provide habitat to wildlife. An urban forest also increases property value and happiness. Our gardens can further help us adapt to climate change by growing food (reducing reliance of imported produce).
Vancouver's urban forest today is made up of:
140,000 street trees
300,000 park trees
Unknown number of private trees
11% of canopy on streets
27% of cnapopy in parks
62% of canopy on private property
Vancouver aims to increase tree canopy from 18% to 22% by 2055
through better management and replanting 150,000 trees by 2020.
"Over the past two decades, 23,490 healthy, mature trees were removed from private properties (including residential,
institutional, commercial and industrial land). In 2013...about 5 healthy, mature trees were removed everyday."

BC's carbon reduction targets and tree planting targets are for all of our benefits; we must do our share to keep to 2°C of warming.
We also need to prepare for the impacts of climate change. We can begin to cut our emissions, for example, by taking better care of trees in our neighbourhood, switching to renewable energy sources, driving less, or switching to hybrids or electric vehicles, and taking better care of our neighbourhood trees.

Renewable energy is the energy generated from natural processes that is continuously replenished. This includes sunlight,
geothermal heat, wind, tides, water, and various forms of biomass, which will not be exhausted and is constantly renewed.
Renewable energy will become one of the most effective tools for us to combat climate change as these sources displace traditional carbon-intensive fossil fuels (the main cause of anthropogenic climate change). Furthermore, the technologies can save us money and increase more job opportunities in the long run.

Vancouver aims to
- Derive 100% of the energy used in Vancouver from renewable sources before 2050.
- Reduce greenhouse gas emissions by at least 80% below 2007 levels before 2050.

Why do we need renewable energy?
Renewable energy sources diversify and localize energy supplies, emit little or no carbon into the atmosphere, and lower the costs of building maintenance. They are also less detrimental to human health than fossil fuels.
Why does Vancouver aim to achieve this goal?
Metro Vancouver, has massive capacity (rich in natural resources such as wind power, hydrology and biomass) to provide its own renewable energy within the borders, but this potential is currently barely utilized. As cities continue to grow, we must look at local sources of heat, cooling, and electricity that are sustainable in the long-term.
