Solution for global warming

The Sustainable Development Goals spell out how we can protect our environment and slow climate change, from forests to oceans to everywhere in between. Think about your electricity use and your travel. Check your dinner table. Reuse whatever you can. The possibilities for action are many – and add up fast. Save energy at home Much of our electricity and heat are powered by coal, oil and gas. Use less energy by reducing your heating and cooling use, switching to LED light bulbs and energy-efficient electric appliances, washing your laundry with cold water, or hanging things to dry instead of using a dryer. Improving your home’s energy efficiency, through better insulation for instance, or replacing your oil or gas furnace with an electric heat pump can reduce your carbon footprint by up to 900 kilograms of CO2e per year. Change your home's source of energy Ask your utility company if your home energy comes from oil, coal or gas. If possible, see if you can switch to renewable sources such as wind or solar. Or install solar panels on your roof to generate energy for your home. Switching your home from oil, gas or coal-powered energy to renewable sources of energy, such as wind or solar, can reduce your carbon footprint by up to 1.5 tons of CO2e per year. Walk, bike or take public transport The world’s roadways are clogged with vehicles, most of them burning diesel or gasoline. Walking or riding a bike instead of driving will reduce greenhouse gas emissions -- and help your ...

Ensuring a safe future below the 1.5°C mark requires the world to cut 30 gigatonnes greenhouse gas emissions annually by 2030. Transport and industry are not enough. We need to cut carbon emissions by managing our land and resources more efficiently, including building smart cities and curbing deforestation and food waste.

Forego Fossil Fuels—The first challenge is eliminating the Oil is the lubricant of the global economy, hidden inside such ubiquitous items as plastic and corn, and fundamental to the transportation of both consumers and goods. Coal is the substrate, So try to employ alternatives when possible—plant-derived plastics, biodiesel, wind power—and to invest in the change, be it by divesting from oil stocks or investing in companies practicing carbon capture and storage. Infrastructure Upgrade—Buildings worldwide contribute around one third of all greenhouse gas emissions (43 percent in the U.S. alone), even though Of course, it takes a lot of cement, a major source of greenhouse gas emissions, to construct new buildings and roads. The U.S. alone contributed 50.7 million metric tons of carbon dioxide to the atmosphere in 2005 from cement production, which requires heating limestone and other ingredients to 1,450 degrees Celsius (2,642 degrees Fahrenheit). Mining copper and other elements needed for electrical wiring and transmission also causes globe-warming pollution. But energy-efficient buildings and Move Closer to Work—Transportation is the second leading source of greenhouse gas emissions in the U.S. (burning a single gallon of gasoline produces 20 pounds of CO 2). But it doesn't have to be that way. One way to dramatically curtail transportation fuel needs is to move closer to work, use mass transit, or switch to walking, Cutting down on long-distance travel would also help...

Update 7/2/2020: The lifecycle emissions figures were revised to reflect more recent data on electricity carbon intensity and battery manufacture. Electric vehicles (EVs) are an important part of meeting global goals on climate change. They However, while no greenhouse gas emissions directly come from EVs, they run on electricity that is, in large part, still produced from fossil fuels in many parts of the world. Energy is also used to manufacture the vehicle – and, in particular, the battery. Here, in response to recent misleading media reports on the topic, Carbon Brief provides a detailed look at the climate impacts of EVs. In this analysis, Carbon Brief finds: • EVs are responsible for considerably lower emissions over their lifetime than conventional (internal combustion engine) vehicles across Europe as a whole. • In countries with coal-intensive electricity generation, the benefits of EVs are smaller and they can have similar lifetime emissions to the most efficient conventional vehicles – such as hybrid-electric models. • However, as countries decarbonise electricity generation to meet their climate targets, driving emissions will fall for existing EVs and manufacturing emissions will fall for new EVs. • In the UK in 2019, the lifetime emissions per kilometre of driving a Nissan Leaf EV were about three times lower than for the average conventional car, even before accounting for the falling carbon intensity of electricity generation during the car’s lifetime. • Co...
