This nine-part history of Exxon’s engagement with the emerging science of climate change is the result of an eight months-long investigation conducted in 2015. The stories span four decades, and are based on primary sources, including internal company documents dating back to the late 1970s; interviews with former company employees; and other evidence published for the first time by ICN.

The following text was released by the Governments of the United States of America and the European Union.
Today, the United States, the European Union, and 11 countries launched the Global Methane Pledge Energy Pathway to catalyze methane emissions reductions in the oil and gas sector, advancing both climate progress and energy security.

It refers to future increases in global temperatures that will be caused by greenhouse gases that have already been emitted. In other words, if the clean energy transition happened overnight, how much warming would still ensue?

This fast-track consensus study will develop a framework for evaluating global anthropogenic greenhouse gas (GHG) information to support decision making. The committee will examine emerging approaches that supplement self-reported data with other independent data sources in the development and evaluation of global anthropogenic GHG emissions inventories.

A wide range of strategies are available to help organizations reduce their greenhouse gas (GHG) emissions. Below are a list of resources and guides to help your organization identify and implement GHG reduction opportunities.

Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are:

Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions. The first graph shows atmospheric CO2 levels measured at Mauna Loa Observatory, Hawaii, in recent years, with the average seasonal cycle removed. The second graph shows CO2 levels during the last three glacial cycles, as reconstructed from ice cores.

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years.1 The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.

Methane is the world’s simplest hydrocarbon, with a chemical formula of CH4 (one atom of carbon and four

ncreases in the abundance of atmospheric greenhouse gases since the industrial revolution are mainly the result of human activity and are largely responsible for the observed increases in global temperature [IPCC 2014]. Because climate projections have large model uncertainties that overwhelm the uncertainties in greenhouse gas measurements, we present here an observationally based index that is proportional to the change in the direct warming influence since the onset of the industrial revolution (also known as climate forcing) supplied from these gases.
