R-2000 Protecting Our Environment

Protecting Our Environment

The effects of climate change

Climate change is affecting the weather and the stability of ecosystems in Canada and around the world. Every time we use energy from fossil fuels, we create the greenhouse gases that contribute to climate change. The Government of Canada is committed to reducing these emissions in order to protect the environment from the widespread effects of climate change.

How R-2000 helps

When you choose an R-2000 certified home, not only do you get an advanced new home, you also help combat climate change and the depletion of our natural resources.

R-2000 homes lessen our impact on the environment by:

Reducing greenhouse gases

The energy efficiency built into every R-2000 home helps reduce the production of greenhouse gases. Carbon dioxide (CO2) that is produced when we burn oil, natural gas and other fossil fuels is the most significant cause of climate change. The average new home in Canada releases five tones of CO2 each year. R-2000 certified homes cut these emissions by about 30 percent.

Creating a market for recycled products

R-2000 certified homes use a range of advanced building products made from recycled materials. This can include drywall, wood and steel studs, insulation, roofing, concrete and even carpeting. By providing a market for these new products, R-2000 helps make our recycling efforts work.

Making better use of natural resources

Many new building systems used in R-2000 homes make better use of natural resources. For instance, engineered wood products ranging from floor systems to support beams are made from the fibre of fast-growing tree species that aren't suitable for lumber production.

Protecting water quality

R-2000 homes also help protect the water quality in our rivers and lakes. Every R-2000 home comes with a number of water-conserving fixtures such as toilets, faucets and showers. This means your community has less water to purify and less sewage to treat. Water conservation makes great environmental sense. It also cuts your monthly energy and utility costs.

How does your home compare with an R-2000 certified home?

R-2000 certified homes are more environmentally friendly than newly built conventional homes.

The chart below shows the average yearly CO2 emissions resulting from energy use in homes of different ages.

For the purposes of this comparison:

all houses are:

  • Based on HOT2000* archetype houses developed for climate change studies
  • Use natural gas for space heat and hot water for a house located in Ottawa
  • Conventional houses built in 1970 to 1980 have space heat energy normalized for a house with a volume of 720 m3
  • Greenhouse gas emissions are CO2 equivalent
  • 1 t = 1 (metric) tonne = 1000 kg
