In order to avoid dangerous climate change, global greenhouse gas emissions must peak and then rapidly decline to near zero by mid-century. Healthy ecosystems can provide 37 percent of the mitigation needed to limit global temperature rise, but damaged ecosystems release carbon instead of storing it. Food production is a major source of carbon dioxide, methane, and other greenhouse gases. Lucas Chancel's recent report estimates that the carbon emissions per passenger for an 11-minute spaceflight are at least 75 tons.
Developed countries must reduce their emissions faster than developing countries in the short term for reasons of equity and fairness. Carbon inequality analysis should be placed at the heart of governments' efforts to reduce emissions. The Emissions Gap Report evaluates the gap between anticipated emissions in 2030 and levels consistent with the 1.5°C and 2° C targets of the Paris Agreement each year. To reduce emissions in industry, materials must be used more efficiently, products must be reused and recycled, and waste must be minimized.
Under an Emissions Trading System (ETS), the price of carbon fluctuates according to market demand for emissions, but the total amount of emissions is known. Stopping rampant deforestation, especially of the world's rainforests, which account for up to 10% of the world's carbon dioxide emissions, is also a vital step. Reverse your lagging global position on climate issues and demonstrate your commitment to reducing GHG emissions using the most modern and effective techniques available. By 2030, Chinese citizens will be responsible for nearly a quarter (23 percent) of the emissions of the richest 1 percent, U.
S. citizens one-fifth (19 percent) and Indian citizens one-tenth (11 percent). The Working Group on National Greenhouse Gas Inventories develops methodologies for measuring emissions and removals.The European Union Emissions Trading Scheme (EU ETS) is the largest and most famous cap-and-trade system that covers emissions from factories, power plants and other facilities in 30 countries (all EU countries plus Iceland, Liechtenstein and Norway), resulting in coverage of about 40% of the EU's greenhouse gas emissions.If no action is taken, international flights could produce more than 20% of global CO2 emissions by 2050 as other sectors decarbonize. Only the emissions of the richest 10 percent could push us beyond the agreed limit in the next nine years.
The price of carbon will force companies to reevaluate their long-term investment decisions, leaving aside emission-intensive production towards low-carbon technologies.
