STATEMENT: Government’s New Climate Target Cements Canada’s Position as a Global Laggard

Enviromental Defense

A target of 45 to 50 per cent reductions from 2005 levels by 2035 represents no meaningful increase in ambition from Canadas current 2030 target. In recent advice to the government, the Net Zero Advisory Body made clear that even a 50 to 55 per cent reduction wouldnt represent Canada doing its fair share in reducing greenhouse gas pollution.

The CO2 problem in six easy steps (2022 Update)

Real Climate

Step 1: There is a natural greenhouse effect. Thus there must be a large amount of IR absorbed by the atmosphere (around 158 W/m 2 ) – a number that would be zero in the absence of any greenhouse substances. Step 2: Trace gases contribute to the natural greenhouse effect. The Earth’s Energy Budget (NASA).

It is significant because if its huge public health benefits and because it has provided the basis for EPA regulation of greenhouse gases. This California law imposes limits on greenhouse gas emissions from new vehicles, a breakthrough in U.S. If I were listing laws in order of importance, I would put the CAA on top. Pavley Act.

How Does Transit Help the Climate?

Union of Concerned Scientists

Transportation is now the largest source of US greenhouse gas emissions. The country had a dip in transportation emissions around 2005 after Hurricane Katrina, when damage to refineries and production caused oil prices to spike above $70 a barrel (that’s a lot). Bleviss, 2020 ).

Statement on Canada’s Latest Greenhouse Gas Emissions Data

Enviromental Defense

The new information shows that in 2021 GHG emissions were over eight per cent lower than in 2005. However, to reach the federal government’s 2030 climate targets – a 40-45 per cent reduction from 2005 levels – significantly more reductions are needed. This reduction in emissions is a critical indicator of climate progress.
