April 1 (Reuters) - Many European energy majors have in

recent weeks weakened their emissions cuts and renewable energy

targets, as big U.S. oil and gas producers still lag their

European rivals in setting climate targets.

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 have different approaches to intensity-based

targets and how they 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, biofuels or carbon offsets 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.

In March, TotalEnergies said its indirect emissions would

likely rise as it sells more natural gas, and that the planet's

overall emissions would fall as gas replaced dirtier fuels,

including coal and fuel oil.

In February, BP revamped its strategy to cut spending on

renewables and lower-carbon solutions and dropped a target for

absolute Scope 3 emissions cuts by 2030.

In recent weeks, Equinor ( EQNR ) scrapped its 2030 target for

investments in renewables, cut its installed renewable energy

goal and softened its medium-term net carbon intensity targets.

Eni confirmed its main decarbonisation targets in February

and said it would press ahead with its strategy to sell stakes

in its low-carbon units Plenitude and Enilive.

The table below shows details by company (in alphabetical

order).

NOTES:

1) Scope 1 refers to emissions from a company's direct

operations, such as a diesel generator on an offshore platform.

2) Scope 2 emissions include those from the power a company

uses for its operations and from its fleet of vehicles.

3) Scope 3 includes emissions from the combustion of the

products a company sells, such as gasoline or jet fuel.

Typically these account for around 90% of emissions at an

integrated oil and gas company.
