Oil has production contribution to more climate change. Coronavirus carbon emissions.

The research, published in the scientific journal Nature, indicates methane emissions from fossil fuel sources are between 25% and 40% higher than previously estimated.

Scientists looked at ancient air bubbles trapped in Greenland’s ice sheet.

They measured a rare radioactive isotope to work out how much atmospheric methane comes from fossil sources, as opposed to biological sources. They found that nearly half of the methane in our air comes from oil and gas production.

The reduction in emissions is mostly a result of lower output from oil refineries and lower coal use for power generation and steel-making, as China's government struggles to control the epidemic.

One of the deadliest epidemics in decades has dented energy demand and industrial output in China, cutting carbon dioxide emissions by about 100 million metric tonnes-close to what Chile emits in a year.

Over that period in 2019, China emitted 400 million metric tonnes of carbon dioxide; this year's figure is likely closer to 300 million metric tonnes.

There were over 74,000 confirmed cases of people infected with the coronavirus in mainland China as of Feb 18, according to the National Health Commission with the death toll at 2,004.

Research from BloombergNEF released on Tuesday shows that, despite the erosion in China's productivity, the country's emissions could still increase due to an infrastructure-focused stimulus package being prepared by the government, which will require the country to continue burning coal and increase its use of cement and steel.

More than 100 cities around the world, including Mexico City, Cape Town, New York, and Boston have been named on CDP’s Cities A List for their transparency and action on climate change.

Designed to push cities to ramp up their climate action and ambition, CDP’s scoring and A List is based on data reported by more than 850 cities through the CDP-ICLEI Unified Reporting System in 2019.

Cities measure and report key environmental data like their emissions, climate-related vulnerabilities, and actions to reduce emissions and adapt to risks. They are scored A to D based on completeness and quality of their data, and the level of action taken.

To score an A, a city must have a city-wide emissions inventory, have set an emissions reduction target, published a climate action plan, and have completed a climate adaptation plan to demonstrate how it will tackle climate hazards now and in the future, among other actions.

Analysis has shown that, on average, cities on the A List are taking more than three times as many climate actions as non-A List cities. This represents five times as many actions to cut emissions and curb future warming, and twice as many to adapt to current climate hazards, from flooding to extreme heatwaves.

Examples of city climate leadership include: Greater Manchester, United Kingdom: The city set the target to become carbon neutral by 2038 — 12 years ahead of the UK Government. This is a target that demands annual emissions reductions of 15%. The city is working to add at least an extra 45MW of locally generated and renewable electricity to the grid by 2024.

eThekwini, South Africa: The city aims for 40% of electricity consumption to be met by renewables by 2030. It will also ensure that 70% of private electricity demand is supplied by self-generated renewable energy by 2050. To make this technology accessible, eThekwini has launched a number of solar energy and energy efficiency programs, such as a GIS-based solar map and framework, which will enable users to plan rooftop installations. Additionally, the city is poised to enact a by-law requiring buildings to be retrofitted with energy efficient technologies by 2030, and all new buildings to be net zero carbon by 2030.

Petaling Jaya, Malaysia: In 2011, the city of Petaling Jaya launched a low carbon tax assessment scheme that provides tax rebates to residents that undertake low carbon building retrofit measures and make more sustainable lifestyle choices, such as ownership of hybrid/electric vehicles. Since its inception, the project has achieved estimated emissions reductions of 200tCO2e per annum. The only local council in Asia to launch such an incentive for homeowners, the Petaling Jaya Homeowners Low Carbon and Green Initiative, has waived RM414,380 or USD101,700 for 1,240 households in the city up to 2018.

Fayetteville, USA: One of 125 city signatories of the “We Are Still In” agreement, Fayetteville, AR has committed to convert all facilities to 100% renewable energy by 2030, and reduce emissions 40% by 2030 and 80% by 2050.

In response to local and regional governments calling for a simpler reporting process, the CDP-ICLEI Unified Reporting System was launched in April 2019. The same year, more than 850 cities disclosed information, compared to 43 in 2011. This steep increase reflects the growing number of cities taking action to lead the transition to a low carbon, sustainable econom.y
