How We Measure Greenhouse Gas Emissions

When we talk about Climate Change we usually talk about the need to reduce greenhouse gases (GHGs). Each year in the region, 15 million tonnes of greenhouse gases are released. Metro Vancouver wants to reduce these emissions by 80 per cent by the year 2050.

But, how do you measure 15 million tonnes of GHGs??
Well, turns out you don’t – they’re calculated.

Greenhouse gases are created when fuels are burned. If you know how much fuel is being burned you can figure out how many GHGs are being created. So, the data nerds and engineers at Metro Vancouver gather fuel consumption data from a whole bunch of sources, add in some chemical formulas, and then mass of emissions can be estimated.

GHG calculation

For things that move around like the family car, ships, aircraft, trains, heavy duty trucks, bulldozers and tractors, federal agencies like Transport Canada and provincial agencies like ICBC, can tell us how many of these vehicles there are in the region. Combine that with fuel consumption data and you can come up with a good idea of total emissions.

GHGs federal agencies

So that makes up about a half of the greenhouse gases – of which about 30 per cent is from cars and trucks. Next, coming in at about 25 per cent are things that stay put: namely, buildings.
For example, rooftop vents release CO2 in the process of heating and cooling buildings. Natural gas provider FortisBC provides the information needed for most of these calculations. Industrial facilities also track their fuel use and report to Metro Vancouver. And then those data nerds go to work to calculate the GHGs emitted by this sector.

Data is also collected on a range of other emission contributors, like cement production, petroleum refining, landfilling, and agriculture. There is a bit more fine tuning to meet United Nations International Climate Change protocols, but generally, that’s how we measure greenhouse gas emissions.

Improving Access to EV Charging in Multi-family Dwellings

Most electric vehicle charging takes place at home, which can be a challenge for apartment dwellers as multi-family buildings comprise about half the housing choices in the region. New bylaws and incentives are advancing EV charger requirements in multi-family dwellings in the region, such as the City of North Vancouver’s newly established guidelines.

Metro Vancouver Close Up – West Vancouver Looks Forward With Community Energy and Emissions Plan

West Vancouver Community Energy and Emissions Plan (CEEP) MVCU from Metro Vancouver on Vimeo.

mvconnectHoverWest Vancouver’s location between the Burrard Inlet and the North Shore mountains makes for a beautiful setting. But it also leaves it vulnerable to climate change impacts — such as sea level rise and extreme weather events. So the municipality is looking to the future and seeking local input in the effort to reduce greenhouse gas emissions — through the creation of a community energy and emissions plan (CEEP).

Caring for the Air – How Metro Vancouver’s Wood Stove Programs Reduce the Impact of Wood Smoke

Screen Shot 2015-09-08 at 5.06.23 PM

Modern units can reduce harmful particulate emissions compared to traditional stoves and fireplaces

Many people believe that wood smoke is natural and not harmful to breathe. Actually, wood smoke is made up of fine particulate matter (PM2.5) and a mix of chemicals that can be hazardous to human health. Also, wood smoke is estimated to be the leading contributor of PM2.5 emissions in the region. To reduce the impacts of wood smoke on our air quality Metro Vancouver offers homeowners a cash incentive to upgrade their fireplace or wood stove.
