Cooking Oil and Climate Change
- What most people don't know, however, is that conventional methods for
extracting oil from plant materials require enormous amounts of energy, which in
turn produce significant greenhouse gas emissions.

Burning Takes Bite Out of Landfill Gas
- Understanding more about emissions from these stationary sources — and the
effectiveness of technologies being used to control them.

Study Examines Sources and Formation of Particulates
- an effort to better understand the sources, formation and distribution of
particulate matter and ground-level ozone.

New Technologies Turn Out Cleaner Dirt
- The Membrane-Assisted Soil Leaching (MASL) process is designed to remove heavy metals, such as mercury, lead, arsenic,
chromium, copper and cadmium, from sites contaminated by mining, smelting, old
batteries, leaded fuels and other spills.

In the Thick of the Slick
- Now, after more than 10 years of research and development, scientists are flight-testing a prototype sensor
that can measure the thickness of an oil slick on water from the air.

Tapped Tailpipes Help Profile Particles
- The project is aimed at developing detailed emissions profiles—including chemical make-up and size distribution—of fine particulate
matter emitted from motor vehicles.

Missile Sites Targeted for Clean-Up
- Environment Canada recently completed a training and technology transfer project aimed at enabling the former Soviet republic to return this land to arable
use.

Portable Burner to Clean Canada's Arctic
- Leaking or corroded fuel containers are an environmental hazard in any
region of the country, but pose a particularly serious threat in fragile
ecosystems like the Arctic.

The two-stroke solution
- In Pakistan, vehicle emissions account for 90% of air pollution. EC and others
are working on a way to reduce the fumes from a major troublemaker—the
auto-rickshaw.

Bio-Markers Clues in Chemical Sleuthing
- When the Exxon Valdez ran ashore off the coast of Alaska ten years ago,
there was no doubt as to the source of the oil that washed over the coastline
and threatened the fragile ecosystem.

Sensor a Revolution in Spill Detection
- Beginning early this year, the world's most advanced system for detecting and
classifying oil spills will begin operation aboard a DC-3 aircraft based in
Ottawa.

The Leader of the Pack
- tests conducted at Environment Canada’s Environmental Science and Technology Centre (ESTC)
show that individually, motorcycles can emit considerably higher levels of air
pollutants than cars and light-duty trucks.
