Guidance Document - Heavy-Duty Vehicle and Engine Greenhouse Gas Emission Regulations

Amendments that modify Heavy-Duty Engine and Vehicle Regulations

Amended

Law passed

The purpose of these Regulations is to reduce greenhouse gas emissions from heavy-duty vehicles and engines by establishing emission standards and test procedures that are aligned with the federal requirements of the United States. On June&nbsp;29,&nbsp;2021, the United States Environmental Protection Agency (U.S. EPA) published a Final Rule in the Federal Register, entitled <a rel="noopener noreferrer" href="https://www.federalregister.gov/documents/2021/06/29/2021-05306/improvements-for-heavy-duty-engine-and-vehicle-test-procedures-and-other-technical-amendments" target="_blank">Improvements for Heavy-Duty Engine and Vehicle Test Procedures, and Other Technical Amendments</a> that introduces technical amendments to the U.S. EPA emission regulations to modify existing test procedures and other provisions for vehicles and engines.Canadian vehicle and engine emission regulations are aligned with the U.S. EPA emission regulations Consequently, on December 18, 2021, the Heavy-duty Vehicle and Engine Greenhouse Gas Emissions Regulation was amended to maintain alignment with the corresponding technical amendments in the US EPA’s Final Rule.&nbsp;

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.

The management and allocation of funds, assets and investments to meet various objectives

A long-lived, colourless gas, chiefly emitted from fossil fuel combustion, deforestation and cement production.

Production of electricity and heat from solar irradiation.

This sector provides communication services, software development, and IT solutions.

The activities of industries that transforms raw materials into finished goods through industrial processes.

Air pollution involves harmful contaminants in the air, affecting both indoor and outdoor environments. It can lead to health issues like respiratory diseases and heart problems, and climate impacts such as global warming. Pollutants can damage plants, trees, habitats, and water bodies like rivers and lakes.

Oil is a combustible liquid fossil fuel composed mainly of hydrocarbons, occurring as crude oil and refined into petroleum products such as petrol, diesel and kerosene.

Codes and standards are regulatory instruments that specify minimum standards to protect health and safety. This ranges from performance standards, which prescribe outcomes while allowing flexibility to achieve compliance, to the more prescriptive approach of technology-specific standards.

A potent, short-lived greehouse gas, largely released from livestock, fossil fuel extraction and waste management.

This sector involves activities to move goods and people, alongside the storage of products.

Fossil gas, commonly known as natural gas, is a fossil fuel consisting chiefly of methane with smaller amounts of other hydrocarbons and trace gases, found in underground deposits.
