Nov 12 (Reuters) - The world's biggest oil and gas

companies have set varying targets to reduce greenhouse gas

emissions from their operations and the combustion of the

products they sell.

On Tuesday, Shell won an appeal against a landmark 2021

ruling that required it to cut its absolute carbon emissions by

45% by 2030 compared to 2019 levels, including those caused by

the use of its products.

Scientists say the world must cut greenhouse gas emissions

by around 43% by 2030 from 2019 levels to stand any chance of

meeting the 2015 Paris Agreement goal of keeping warming well

below 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial

levels.

Direct comparisons of the oil companies' climate plans are

difficult as they emphasise different approaches to

intensity-based targets and how to include greenhouse gases from

the combustion of their fuels - known as Scope 3 emissions.

Intensity-based targets measure the amount of greenhouse gas

(GHG) emissions, such as methane and carbon dioxide, per unit of

energy or barrel of oil and gas produced.

That means absolute emissions can rise even if the headline

intensity metric falls - for example with the addition of

renewables or biofuels to the product mix.

Reducing emissions will require a well-functioning market

for carbon, the scaling up of carbon capture and storage

technology, and the development of competitive uses of hydrogen,

many of the companies have said.
