Climate change mitigation consists of actions to limit global warming and its related effects. Due to massive price drops, wind power and solar photovoltaics PV are increasingly out-competing oil, gas and coal [5] though these require energy storage and improved electrical grids. Once that low-emission energy is available, transport and heating can shift to these mostly electric sources. Mitigation of climate change may also be achieved by reforestation and forest preservation [3] and the enhancement of carbon sinks. Methane emissions, which have a high short-term impact, can be targetted by reductions in cattle and more generally by reducing meat consumption. Political and economical responses include carbon taxes and other emission pricing models, abolishing fossil fuel subsidies , simplified regulations for the integration of low-carbon energy and divestment from fossil fuel finance.

Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide CO2 when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [ 1 ]. The drilling and extraction of natural gas from wells and its transportation in pipelines results in the leakage of methane, primary component of natural gas that is 34 times stronger than CO2 at trapping heat over a year period and 86 times stronger over 20 years [ 3 ]. Whether natural gas has lower life cycle greenhouse gas emissions than coal and oil depends on the assumed leakage rate, the global warming potential of methane over different time frames, the energy conversion efficiency, and other factors [ 5 ]. One recent study found that methane losses must be kept below 3. And if burning natural gas in vehicles is to deliver even marginal benefits, methane losses must be kept below 1 percent and 1.

Climate Accountability Institute releases treasure trove of data on fossil fuel company operational and product-related emissions. Update 8 October Accounting for carbon and methane emissions, Top Twenty investor-owned and state-owned oil, gas, and coal companies CAI has updated all Carbon Majors to activity data, and we post a sample of the results and individual worksheets below:. Heede concludes that nearly two-thirds of carbon dioxide emitted since the s can be traced to the 90 largest fossil fuel and cement producers, most of which still operate today. The primary objective is to quantify and trace historic and cumulative emissions of carbon dioxide and methane to the largest extant fossil fuel and cement producers.

Climate change mitigation

The combustion of fossil fuels is by far the largest human source of global greenhouse gas emissions, releasing more than 30 billion tonnes of carbon dioxide CO 2 into the atmosphere each year IPCC Reducing fossil fuel combustion is thus a top priority for climate policy. For decades, national policymakers and international agreements have sought to achieve this goal through promoting energy efficiency, low-carbon technologies, carbon pricing, and other measures aimed at reducing the demand for fossil fuels. Recognizing this shortcoming, policymakers, investors, researchers, and civil society actors have begun to look at the supply side of the fossil fuel economy—and the potential for supply-side measures to complement demand-side climate policies. A key insight driving these new approaches is that the political and economic interests and institutions that underpin fossil fuel production help to perpetuate fossil fuel use and even to increase it. From this emerging vantage point, continued investment in fossil fuel exploration, extraction, and delivery infrastructure makes global climate protection objectives much harder to achieve.

Climate change mitigation

All emission estimates from the Inventory of U. Greenhouse Gas Emissions and Sinks: — Larger image to save or print 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 years.

Kasting Much has been said and written about the probable effects of human activities on the Earth's climate. Without question, the concentrations of carbon dioxide and the other greenhouse gases that act to keep the planet warm--and therefore habitable--are increasing very rapidly, and governments around the world are rightfully concerned about what we need do about it. A wealth of information has been gathered on different aspects of the problem, and since the Intergovernmental Panel on Climate Change IPCC has published a continuing series of reports that represent an unprecedented international consensus of scientific and economic thinking.
