Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.

Sources of Greenhouse Gas Emissions

• Overview.
• Electricity.
• Transportation.
• Industry.
• Commercial/ Residential.
• Agriculture.
• Land Use/ Forestry.

Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere.

By 2030, China aims to lower carbon dioxide emissions per unit of GDP by over 65 percent from the 2005 level, raise the share of non-fossil energy in primary energy use to around 25 percent, and bring the total installed capacity of wind and solar electricity to more than 1200GW.

The Chinese government announced in March 2018 that it had achieved its Copenhagen emission reduction targets for 2020, which included reducing carbon intensity by 40 to 45 percent and raising the share of non-fossil fuel energy sources to 15 percent.

The Chinese government also devotes much attention to water and soil conservation. It has effectively prevented soil erosion and improved the ecological environment and agricultural conditions. At present, 25 key soil erosion control areas have been established at the national level.

TOKYO — As Prime Minister Yoshihide Suga declared recently that Japan will become carbon neutral by 2050, the country has begun to move toward effectively slashing carbon dioxide emissions to zero within the next three decades. Japan will now expand the previous policy goal of an 80% cut by 2050.

Many governments are now moving in the right direction. By early 2021, countries representing more than 65 per cent of global carbon dioxide emissions and more than 70 per cent of the world economy, will have made ambitious commitments to carbon neutrality.

This balance – or net zero – will happen when the amount of carbon we add to the atmosphere is no more than the amount removed. To reach net zero, emissions from homes, transport, agriculture and industry will need to be cut.

The United States has set a goal to reach 100 percent carbon pollution-free electricity by 2035, which can be achieved through multiple cost-effective pathways each resulting in meaningful emissions reductions in this decade.

The government aims to reduce the more than 1 billion tons of greenhouse gases the country emitted in 2018, according to the trade ministry, to 930 million in 2030 and net zero by 2050. At the same time, the ministry projects that domestic demand for electricity will grow by between 30% and 50% by 2050.

In 2019 Japan emitted 1212 Mt CO2eq and was the 5th largest producer of carbon emissions. As of 2019 greenhouse gas emissions by Japan are over 2% of the annual world total, partly because coal supplies about a third of its electricity….Greenhouse gas emissions.
