Primary production includes the smelting or refining of base metals from feedstock that comes primarily from ore. Secondary production processes includes the recovery of base metals from various feedstock materials, such as recycled metals. Process activities may include the removal of impurities using carbonate flux reagents, the use of reducing agents to extract metals or slag cleaning, and the consumption of carbon electrodes.

Carbon dioxide equivalent (CO₂ eq) means a unit of measure for comparison between greenhouse gases that have different global warming potentials (GWPs). Since many greenhouse gases (GHGs) exist and their GWPs vary, the emissions are added in a common unit, CO₂ equivalent. To express GHG emissions in units of CO₂ equivalent, the quantity of a given GHG (expressed in units of mass) is multiplied by its GWP.

CAS Registry Number means the Chemical Abstracts Service Registry Number.

Cement production means all processes used to manufacture portland, ordinary portland, masonry, pozzolanic or other hydraulic cements.

CEMS means Continuous Emission Monitoring system.

CKD means cement kiln dust.

Fugitive emissions means releases from venting, flaring or leakage of gases from fossil fuel production and processing; iron and steel coke oven batteries; CO₂ capture, transport, injection and storage infrastructure.

GHGs means greenhouse gases.

GWP means global warming potential and allows the comparison of the global warming impacts of different gases. It is a measure of how much energy the emissions of 1 tonne of a certain gas will absorb over a given period of time, compared to the emissions of 1 tonne of carbon dioxide (CO₂). The time period for GWPs used for GHG reporting as per international reporting standards is 100 years. The larger the GWP, the more the given gas impacts global warming compared to CO₂.

Background

Canada is working towards fulfilling its climate change policy objectives, in part by ensuring that it has the capacity to quantify, track and report progress on the reduction of greenhouse gas (GHG) emissions in a way that meets a required level of accuracy, thoroughness, transparency and public credibility.

The federal government, specifically Environment and Climate Change Canada (ECCC), is responsible for developing and reporting a reliable, accurate and timely Greenhouse Gas Inventory for Canada as part of its obligations under the United Nations Framework Convention on Climate Change (UNFCCC). To fulfill its obligations, Canada must estimate its national GHG emissions according to the comprehensive guidance provided by the UNFCCC, which includes reference to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC, 2006),^{Footnote 1}  a key technical document developed by the Intergovernmental Panel on Climate Change (IPCC).^{Footnote 2}

National GHG emissions and removals are reported to the United Nations Framework Convention on Climate Change (UNFCCC) according to the manner, format and frequency dictated by the UNFCCC Reporting Guidelines.^{Footnote 3} Canada’s GHG Inventory is a comprehensive inventory of GHG data and information covering all sources and sinks of GHGs caused by human activity in Canada. The inventory is largely based on emission estimates developed from national and provincial statistics. The facility data collected under the GHGRP is used to compare, validate and in some cases develop the national inventory estimates from industrial sources.

The Government of Canada established the GHGRP in March 2004 under the authority of section 46 of the Canadian Environment Protection Act, 1999 (CEPA) to collect GHG emissions information annually from the largest emitting Canadian facilities. The GHGRP was launched through the publication of the first Canada Gazette notice in March 2004, which set out basic emissions reporting requirements. A Canada Gazette notice is published every year requiring the reporting of GHG emissions for the calendar year specified in the notice and the facility data collected is published annually.

This program is part of Canada’s effort to develop, in collaboration with Canadian provinces and territories, a harmonized and efficient mandatory GHG reporting system that minimizes duplication and reporting burden for industry and governments. Key objectives of the program are to provide Canadians with consistent information on GHG emissions, support the development of emission estimates presented in the Canada’s GHG Inventory and support regulatory initiatives.

In December 2016, ECCC issued a notice of intent in the Canada Gazette indicating its intent to pursue an expansion to the GHGRP in order to enable direct use of the reported data in Canada’s GHG Inventory, to increase the consistency and comparability of GHG data across jurisdictions and to obtain a more comprehensive picture of emissions by Canadian facilities. Notices that were published to require reporting of 2017 and 2018 data represented phases 1 and 2 of the expansion, respectively.
