The literature contains several sources that present a description of the energy sources that are available or are expected to be available during the 21st century. Today's energy options include fossil fuels, nuclear energy, solar energy, renewable fuels, and alternative sources. Fossil fuels are the dominant energy source in the modern global economy, but environmental concerns are prompting changes to an energy supply that is clean. Natural gas is a source of relatively clean energy. Oil and gas fields are considered conventional sources of natural gas.
Recently, global climate change and air quality have become increasingly important environmental concerns. Consequently, there has been a rise in collaborative international efforts to reduce the concentration of greenhouse gases and criteria pollutants. Greenhouse gases include carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), occurring naturally and as the result of human activity. In addition, criteria pollutants (1970 amendments to the Clean Air Act required EPA to set National Ambient Air Quality Standards for certain pollutants known to be hazardous to human health) include emissions of nitrogen oxide, sulfur dioxide, carbon monoxide, and total unburned hydrocarbons. International and national governments are implementing more regulations on air emissions.

It’s no secret that oil majors are among the biggest corporate emitters of pollution. What may be surprising is that they’re reducing their greenhouse-gas footprints every year, actively participating in a trend that’s swept up most corporate behemoths. The Canadian and Alberta governments and three energy companies said on 11 May that they will spend CAD 70 million (USD 51.14 million) to develop three new clean technology projects, aimed at cutting costs and carbon emissions in the country’s oil sands.
OSHA still has a lot of items on its regulatory agenda for 2017-2018, despite President Trump's plans to shrink the agency. The government of Canada has released its proposal for the first federal regulations on greenhouse gas emissions applicable specifically to the upstream oil and gas sector. Canadian regulators are formally proposing rules to reduce methane pollution from the oil and natural gas sector.
Although the Environmental Defense Fund and ExxonMobil are not always aligned on certain important issues, the organizations are working together to understand and reduce methane emissions. Exxon Mobil sent a letter to the US Environmental Protection Agency in support of methane gas emission rules put in place under the Obama administration, according to a copy of the letter seen by Reuters. ExxonMobil announced greenhouse gas reduction measures that are expected to lead to significant improvements in emissions performance by 2020, including a 15% decrease in methane emissions and a 25% reduction in flaring. In November, ExxonMobil signed a commitment with several companies aimed at reducing methane emissions. That agreement built off earlier efforts the company had announced to enhance voluntary methane reduction.
The oil and gas major has set aside $100 million to fund projects that will deliver new greenhouse gas emissions reductions in its upstream oil and gas operations. Chevron plans to set greenhouse gas emissions targets and tie executive compensation and rank-and-file bonuses to the reductions, the oil major said in its latest climate report.
The oil and gas major has set aside $100 million to fund projects that will deliver new greenhouse gas emissions reductions in its upstream oil and gas operations. The emissions intensity of upstream Canadian oil sands production will continue to decline in coming years, falling to 30% below 2009 levels by 2030, a new report by business information provider IHS Markit says. On 26 April 2018, Canada's minister of environment and climate change announced new regulations under the Canadian Environmental Protection Act, 1999, to reduce methane emissions in the oil and gas sector by almost half.
The House voted 218–195 to strip funding for an Obama-era EPA effort to limit methane emissions from new oil and gas drilling sites. A federal appeals court is letting the Trump administration put on hold an Environmental Protection Agency methane pollution rule for oil and natural gas drilling. Public interest groups and local stakeholders at a public hearing on 10 July urged the Environmental Protection Agency to continue to enforce methane regulations. The Trump administration asked a federal appeals court on 7 July to allow it to delay enforcement of an Obama administration rule to limit methane pollution from oil and natural gas drilling. A federal appeals court in Washington ruled on 3 July that the head of the Environmental Protection Agency (EPA) overstepped his authority in trying to delay implementation of an Obama administration rule requiring oil and gas companies to monitor and reduce methane leaks.
